N. G. Patel Institute of Technology, Bardoli, Gujarat, India Email: [email protected], [email protected], [email protected] In the field of engineering and technology, drawing is taken as an expressing medium to express or explain any idea, concept, or principle. And measuring phenomena play a vital role in the drawing which obviously involves measuring instruments. Whether it is physics, chemistry or biology measurement is the key. Therefore, measurement is a phenomenon that is present everywhere. As modern technology increases, different measuring instruments are introduced, but they have certain limitations, such as one instrument can measure up to 4-5 quantities maximum, material failures such as wear and tear errors, decreased accuracy based on prolonged duration, etc.To address these drawbacks and limitations, the development of a unique multi-purpose measuring device that operates on the concept of light source driven by a programmed chip and modern technology-based software that is compact in size, more precise, more stable, more robust and easier to measure.

5th National e-Conference on Advanced Materials and Radiation Physics(AMRP-2020) Electronic and Optical Properties of CuSbS2 Monolayer as a Direct Band Gap Semiconductor for Optoelectronics N. Prudhvi Rajua), Saurav Lahirib) and R. Thangavelc) Condensed Matter Physics Laboratory, Department of Physics, Indian Institute of Technology (Indian School of Mines) Dhanbad-826004, Jharkhand, India Email: a) [email protected], b) [email protected]; c) Corresponding author: [email protected] This work aims to explore the enrich structural, optoelectronic properties of CuSbS2 monolayer using Tran and Blaha modified Becke-Johnson (TB-mBJ) potential within WIEN2k code. The calculated bandgap from the electronic band structure is found to be 0.75 eV, which is direct bandgap in nature. From the partial density of states (PDOS), the conduction band minimum (CBM) is formed mainly with the contribution of Cu-d and Sb-p states, whereas the valance band maximum (VBM) is formed by Cu-d and S-p states. The calculated effective mass of electrons and holes are 0.38 mo and 0.4 mo respectively. Thus, CuSbS2 monolayer showed direct bandgap with optical absorption coefficient > 10-4 cm -1, which makes it suitable candidate for the candidate solar cells. AM-04 Calculation of Force Constants of Sodium by De Launay Angular Force Model Meena Devi Research Scholar, Department of Physics, Jayoti Vidyapeeth Women’s University, Jaipur, Rajasthan, India Email: [email protected] Many Lattice dynamic models were developed in the past to study the lattice dynamics of metals and their properties. In this present study force constants of Sodium metal have been calculated with the help of De Launay Angular force model. The number of force constants varies with the nature and range of atomic interactions. In the phenomenological theories the force constants of Sodium are evaluated by making use of the experimental data on elastic constants at selected wave vectors. The basic equation of De Launay Angular force model relates three elastic constants, force constants as well as two zone boundary frequencies. In the present study, ion-ion interactions of Sodium are considered by neglecting its electron-ion interaction from the proposed relation of DAF model because sodium is the best example of free electron. The force constants of Sodium are calculated here by restricting the range of interaction up to third nearest neighbor. The third angular force constant is considered as neglected because of weaker interaction due to conduction electrons. The purpose of this paper is to calculate force constants of Sodium by De Launay Angular Force Model which can be used in calculation of phonon frequencies of Sodium. Keywords: Conduction electrons, Elastic constant, Force constant, Sodium, Wave vectors, Weak interactions, Zone boundary frequency AM-05 21

Gorakhpur University, Gorakhpur, Uttar Pradesh, India a) Corresponding author: [email protected], b) [email protected] Locked nucleic acid (LNA) has suggested as a potential substitute of Ribose nucleotide in the application of RNA-TFO in blood clearance in cellular processes due to early degradation of Ribose nucleotide. In this work we designed different Recombinant triplexes by substituting LNA in two different sequences of DNA and verify the stability of such type of modified triplexes and determined the binding affinity of TFO with natural DNA duplex. The molecular dynamics principles were used in the simulation. Binding free energies were determined by Molecular Mechanics Generalized Born Surface Area (MMGBSA) approach. The results of simulation suggest that substitution of LNA in DNA sequence can be used as a better substitute for RNA in application modified TFO AM-06 Effect of Dispersion of Ceramic Filler on Thermal, Structural and Transport Properties of Polymer Electrolyte for Electrochemical Applications Nidhi1 a), Sandhya Patel and Ranveer Kumar 1Department of Physics, Dr. Harisingh Gour Vishwavidyalaya, Sagar, M.P. 470003, India a) Corresponding author:[email protected] Nanocomposite polymer electrolyte (NCPE) thin films have established an extraordinary position among all other electrolyte materials because of their applications in electrochemical devices- solid state batteries, sensors and electrochemical display devices etc. Now day’s research interest has been devoted to magnesium ion conducting electrolytes dispersed with nanoparticles, due to their good electrical, thermal and electrochemical properties. This paper provides a NCPE comprises of Polyvinylideneflouride (PVDF) as a host, Magnesium nitrate (Mg(NO3)2) as a ionic salt and TiO2 nanoparticles as a filler have been prepared by solution cast technique. The prepared polymer electrolyte films were characterized by X-Ray Diffraction, Fourier Transform Infrared (FTIR) Spectroscopy and Differential Scanning Calorimetry-Thermal Gravimetric Analysis technique (DSC-TGA). The X-Ray Diffraction (XRD) and FTIR patterns of polymer electrolyte films confirmed the formation of complex. Reduction in the degree of crystallnity of polymer with addition of salt and nano-filler confirmed by DSC Analysis. The composition, frequency and temperature dependence of ionic conductivity measured through Impedance spectroscopy technique of these films. The highest conductivity achieved for composition i.e. PVDF: Mg(NO3)2: TiO2 (70:30:3). The activation energy calculated from the slope of log σ - 1/T plot. The dielectric study was done in wide range of frequency and temperature. A test cell (battery) has been fabricated comprising Mg | NCPE|C-cell (C+ I2+ electrolyte, 5:5:1) and their discharge profile have been drawn. The preliminary studies indicate the suitability of NCPE as electrolyte in solid state magnesium battery. AM-07 22

Among such materials geometrically frustrated spinel system CdCr2S4 has gained vibrant interest as it shows several interesting behaviors and phase transitions in the field-dependent dielectric and magnetic measurements.. In addition it is found that a metal-insulator transition in CdCr2S4 is triggered by the electrical field. In magnetic fields, the resistivity of CdCr2S4 responds similarly to that of CMR (colossal magnetoresistance) manganites making CdCr2S4 the unique compound to possess all four properties of the colossal magnetocapacitive, colossal electrocapacitive, colossal electroresistance (CER), and CMR. These findings open a new venue for searching new materials to show CMR by tuning electric and magnetic fields. These properties can be affected by local distortions and therefore an introduction of suitable local probe technique would be useful to reinterpret the coupling of different physical degrees of freedom in the present system. AM-08 Synthesis and Characterization of BaTi1-xFexO3 Ceramics Devendra Singh1, Anju Dixit1 and Pramod S. Dobal2,a) 1Department of Physics, UIET, C. S. J. M. University, Kanpur-208024. 2Department of Physics, VSSD College, Kanpur-208002. a)Corresponding author: [email protected] In this work, BaTi1-xFexO3 ceramics for x=0 to 0.5 were prepared using solid-state reaction technique and the structural, dielectric, ferroelectric, and ferromagnetic properties of resulting BaTi1-xFexO3 (0.0 ≤ x ≤ 0.5) compositions have been studied. Structural investigations using X-ray diffraction reveal that the Fe doping leads to the development of hexagonal phase as well as an increase in average grain size. The coexistence of tetragonal and hexagonal phases strongly depends upon the Fe concentration. The lattice strain was found to decrease from 4.37 x 10-3 lin-2nm for x=0.0 to 2.31 x 10-3 lin-2nm for x=0.5, whereas the dislocation density was found decreasing from 12.73 x 10-4 to 4.85 x 10-4 dislocations per nm2 with increasing Fe content from x=0.0 to 0.5. A reduction in dielectric constant (from 1534 to 305) and Remnant polarization (from 1.105 μC/cm2 to 0.015 μC/cm2) was observed with increasing x from 0 to 0.5. All Fe doped samples exhibit ferromagnetic ordering with increasing saturation magnetization (Ms) 0.084 emu/g at x=0.1 to 0.511 emu/g for x=0.5 samples. The increase in Ms was found in corroboration with the hexagonal volume fraction in the samples. The ferromagnetic behavior makes Fe doped BT more useful for switching and other applications such as magnetically recorded ferroelectric memory etc. 23

5th National e-Conference on Advanced Materials and Radiation Physics(AMRP-2020) AM-09 An Eddy Current Hall Effect in Semiconductors Aditya N. Roy Choudhury 1,2,a) 1 Department of Energy Science and Engineering, Indian Institute of Technology Bombay, Mumbai 400076, India. 2 A major part of this work was carried out during the author’s PhD at the Department of Physics, Indian Institute of Science, Bangalore 560012, India. a) Corresponding author: [email protected] It is widely known that a time-varying magnetic field induces an eddy current in a conducting material. In a semiconductor, the eddy current and the field jointly generate a time-varying Hall voltage. First investigated more than 50 years ago, this Hall effect is yet to be accurately detected in a laboratory. One of the primary unresolved issues with its measurement is a noise voltage. The noise was not quantitatively investigated or addressed in any of the previously published reports. In this conference proceeding this noise voltage is discussed in details, and proper guidelines are provided so that both the noise and the signal can be individually measured without any bothering interferences. These high transient field Hall measurements can be carried out using home-built, low-cost magnets, and therefore can be setup in any laboratory.

However, phase change materials are available depending on the temperature ranges and applications. In this research work we have chosen kulkote phase change material which can be applied on textile and fibrous surfaces. Application of phase change material is carried by coating method using screen printing method. The coating thickness and percentage add-on on the material was controlled using screen printing technique so that uniformity in coating over the fabric surface can be maintained without variation in their density and distribution. The test samples included woven, knitted and non-woven fabric ones. After the application of kulkote phase change material, the test samples were cured and dried in an oven at 80 0C. The surface morphology of the test samples was studied using scanning electron images (Figure 1). The presence of chemical functional group was analyzed using FTIR spectra data obtained for coated and uncoated samples. Thermal behavior was analysed using DSC test data and graphs of these samples. The results showed the test samples were stable and occurrence of an initial endothermic peak at 50 0C. The polyester coated non-woven fabric showed a peak at 2957 cm1 24

The liquid, as well as vapor, are confined in an annular region enclosed by two rigid cylinders, and the phenomenon of heat/mass transport at the interface is also considered in this analysis. The outer cylinder is swirling in the anticlockwise with constant angular velocity and the magnetic field is applied in the axial direction of the cylindrical flow. The perturbed flow is taken as irrotational meanwhile fluids are taken to be viscous having different dynamic viscosities. A quadratic equation is achieved in terms of growth of perturbations which is depending upon various flow variables such as magnetic field, viscosity, density, swirl, heat transfer coefficient, etc. The magnetic field in the axial direction is found to have stabilizing nature in the stability analysis.

Magnetoelectric coupling requires manipulation of electrical ordering via magnetic field or vice versa. In this work, the magnetoelectric bulk composites of (1-x)Co0.5Ni0.5Fe2O4-xBaTiO3(CNFO-BT) were prepared employing solid state reaction method. The structural studies of CNFO-BT composites by X-ray diffraction method confirm lattice distortion and enlarged strain owing to BT substitution in CNFO. The dielectric and impedance measurement exhibit conventional Maxwell-Wagner polarization and confirm the existence of grain dominated non-debye relaxations phenomena in CNFO-BT composites. The magnetodielectric change and variation of ferroelectric polarization with magnetic field reveal lattice distortion, interfacial charge polarization and restricted ferromagnetic domain wall rotation arising from substitution of BT in CNFO. The magnetic hysteresis curves reveal strong ferromagnetic behavior in all composites.

The X-ray diffraction studies confirm the crystalline nature of the compounds which are formed in a pure single phase. From scanning electron micrographs, the average particle size is found to be increased with increasing Mn content and the sample is becoming porous. Magnetization versus magnetic field studies reveal that as Mn content increases, the saturation magnetization, remnant magnetization and coercivity values decreases which clearly indicates that the antiferromagnetic coupling gets strengthened. This increase in the antiferromagnetic nature is possibly due to the structural distortions in the compounds which give rise to the antiferromagnetic super exchange magnetic interactions between Fe+3 - Fe+3 and Fe+3 - Mn+3. 30

The Bi0.9La0.1FeO3 sample was further studied for frequency dependent dielectric properties at room temperature. The XRD spectrum analysis infers the sample to be crystalline in nature as well as single phased. The XRD spectral study of Bi0.9La0.1FeO3 further reveals its crystallization into the rhombohedral structure with an assigned space group R3c. The intense reflection peaks witness the crystallinity and narrow fullwidth at half maximum indicate the higher average particle size. The average particle size calculated using Scherer’s formula was 47.39nm. The lattice parameters calculated were a = b = 5.5771Å and c = 13.8021Å which witness acquired rhombohedral structure. The dielectric studies reveal the Bi0.9La0.1FeO3 sample to be good dielectric in nature with lower loss values. The ac conductivity study reveals the sample to be resistive to the applied field to a higher value thereby does not respond but after the certain limit of the applied field, the conductivity abruptly increases which is attributed to the release of the charge carriers by the trap centers after a threshold voltage. The intriguing dielectric and loss character infer the Bi0.9La0.1FeO3 sample is feasible for electo-magnetic device application.

XRD patterns of the obtained ceramics are found to be sharp and well defined having no impurity phases for all the compositions. Lattice parameter ‘a’ decreases with increase in the amount of Gadolinium. XRD, FESEM and EDX studies confirm the formation of Sr1-xGdxTi1- yTmyO3- ceramics with required cubic structure. FESEM/EDX analysis reveals that ceramics possess high density with marginal inter-granular porosity. The dielectric studies of the synthesized samples show that the synthesized samples possess high dielectric constants, high ac conductivity and low loss factors. The improvement in the dielectric properties of the synthesized samples has been observed with gadolinium and thulium doping.

University, Sirsa (Haryana)-125055, India aCorresponding author : [email protected], [email protected] In this paper, CoFe2O4 and Co0.8Zn0.1Cd0.1Fe2O4 magnetic nanoparticles have been synthesized by using sol-gel auto combustion method. In this method nitrates of Co, Fe and Cd are used as starting materials and citric acid is used as the fuel. The ratio of metal nitrates to citric acid is taken at 1:3. The prepared nano ferrite powder is sintered at 1000℃ for 1.5 h after TG/DTA thermal studies. The prepared ferrite nanoparticles were characterized by using XRD, SEM- EDS, FT-IR, TEM, VSM AND UV etc. From XRD, it is confirmed that the samples are cubic structure in nature and size of ferrite nanoparticle increases with the doping of Cd2+ due to ionic radius. The morphology and the quantitative analysis of the prepared nanoparticles are studied by using SEM-EDS. The FTIR is used to study the presence of functional groups in the ferrite samples.TEM explained that the ferrite nanoparticles are spherical by shape. Magnetic properties of the ferrite powders have been studied at room temperature using a vibrating sample magnetometer (VSM). From this analysis, the values of the saturation magnetization increase and the coercivity of CoFe2O4 nanoparticles are found to decrease with doping of Cd2+ substitution. 37

Here hydrothermal method has been used for the preparation of Ni-MOF for their application as electrode material in supercapacitors. The prepared Ni-MOF material is characterized structurally by using X-ray diffraction (XRD) and Fourier transforms infrared spectroscopy (FTIR). The electrochemical performance of the prepared Ni-MOF material has been studied by using cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) in 1M KOH aqueous electrolyte solution.

Effective interatomic interaction is deduced within the tight-binding second-moment approximation and extended up to three neighbor distance, as proposed by Karolewski [Radiation Effect & Defects in Solids, 153 (2001) 239]. By simultaneously varying density (ρ) and temperature (T), and observing the simulated system at a regular interval of time, we have estimated melting temperature (2903 K) and corresponding density (8.4915 g/cm3) in agreement with the experimental and recent ab initio MD findings. Further, the pair-correlation function g(r) deduced at presently estimated melting temperature and density is analyzed in terms of coordination number and in reference to the assumed effective interaction potential. Unexpected large coordination number (12.84) found for such a BCC → liquid transition may be attributed to the limitation of the potential. Further, the Fourier transform of g(r) is used to derive static structure factor S(k) and its long wavelength limit is exploited to find compressibility. Relative position and nature of the first and the second peak in S(k) reveal following points: (i) first peak is symmetrical and (ii) the ratio of the position of the second peak to that of the first peak is 1.9013. This confirms that the system is fully melted into the normal liquid phase. AM-43 Review of Blue Phase Liquid Crystal Devices Alka Devi1*, Suman Lal2** and Samriti Khosla1# 40

Shankar,1,a) N. K. Bhatt,1,b) A. B. Patel2 and P. R. Vyas3 1Department of Physics, Maharaja Krishnakumarsinhji Bhavnagar University, Bhavnagar – 364001, Gujarat, India 2Department of Physics and Materials Science, University of Memphis, Memphis, TN – 38152, USA 3Department of Physics, School of Sciences, Gujarat University, Ahmedabad – 380009, Gujarat, India a)Corresponding author: [email protected], b)[email protected], [email protected] Ca-based bulk metallic glasses (BMG) with their unique properties being very low density, good compressive strength and shear modulus comparable to modulus of human bones have found utility in biomedical field. Their poor oxidation and corrosion resistance can be improved substantially when they are synthesized in a glassy state. Although, according to the confusion principle, the bulk form of binary metallic system is seldom possible; recent experimental studies have aimed to achieve these goals and succeeded in preparing CaxAly binary BMG with (x, y) pair as (8, 3), (13, 14) and (61, 39). We examine and verify the amorphous structure and glass forming temperature of binary Ca61Al39(at.%) metallic glass using molecular dynamics simulations combined with an evanescent form for interaction potential at the experimental density. Good agreement is observed with recent in-situ high energy X-ray experimental findings for pair-correlation function ������(������) and static structure factor ������(������). Evidenced from the structural analysis, the estimated liquid to glass transition temperature (Tg) is found between 520 to 555 K. Large principal peak heights in ������(������) and ������(������) is attributed to the strongness of the potential, whereas the large-r Friedel oscillations results in to the oscillatory behavior of ������(������). Nevertheless, present result for co-ordination number (NC) 12.44 to 12.79 is in excellent agreement with the experimental value 11.9 ± 0.3 at Tg, and changes by about 7.6% when 41

5th National e-Conference on Advanced Materials and Radiation Physics(AMRP-2020) temperature is varied from 300 to 1200 K while keeping the density constant. Unlike the other composition pair (x, y) for Ca-based BMG, a large co-ordination number is suggestive, and proposes a closed packed structure in its probable solid phase. Since the closed packed structures are commonly observed with metallic materials, this proposition is partly supported by a successful application of the evanescent form for bare-ion local pseudopotential to analyse the structural aspect of binary Ca61Al39 metallic glass. AM-45 Effect of Sintering Temperature on the Crystal Structure of SrMnO3 Paramvir Kaur1, b) and K. Singh1, a) 1 School of Physics and Materials Science, Thapar Institute of Engineering and Technology, Patiala-147004, Punjab, India a) Corresponding author: [email protected], b) [email protected] SrMnO3 is a potential solid oxide fuel cell (SOFC) cathode material. However, the formation of different crystalline phases and poor sinterability restrict its application as a cathode in SOFC. Thus, the present study is focused on the synthesis of monophasic SrMnO3 using different sintering temperatures with variable sintering durations. The X-ray diffraction confirms the gradual transformation of hexagonal to orthorhombic SrMnO3. Minor amounts of Hausmannite Mn3O4 and Ruddlesden-popper phase Sr4Mn3O10 are also observed. The volume fraction of SrMnO3 increases with the increasing sintering temperature. At the sintering temperature of 1300℃ for 4 hours, the volume fraction of the secondary phases is the minimum.

The XRD patterns reveal polycrystalline nature of the films with hexagonal Wurtzite phase. The particle sizes calculated via Debye Scherrer formula lie between 21 to 66 nm. Presence of tensile strain is observed via Williamson Hall analysis. Almost 3.5 times strain enhancement happens when Al dopant is introduced as compared to undoped ZnO. FE-SEM images show the diverse structures when there is no dopant. Al doping causes uniform and even distribution of particle. The strain augmentation out of Al incorporation supports the creation of uniformity in morphology. 44

The concentration of Pd in nanocomposite system has been varied from 5 at.% to 40 at.%, which shows full range from well below the percolation threshold (30 at. %) to above the percolation threshold value of Pd in matrix. Structural characterizations by GAXRD studies show the presence of (111) peak at around 2θ = 39.8⁰ in nanocomposite film, which reveals the formation of FCC structure of Pd.

NM-04 Theoretical Calculation of Absorption Properties of NiFe@Au Core-Shell Nanoparticles Pradeep Bhatiaa), S. S. Verma and M. M. Sinha Department of Physics, Sant Longowal Institute of Engineering & Technology, Sangrur- 148106, Punjab, India a)Corresponding author: [email protected] The multimetallic nanostructures of a noble metal such as gold, silver, and copper have attracted great attention in alloys and core-shell configuration due to the enhanced plasmonic effect. In this theoretical study, the optical properties of bare NiFe and NiFe@Au core-shell NPs have been calculated using extended Mie theory. The core-size of nanostructures is considered 5 nm to 25 nm and shell thickness systematically varied as 3, 5, 7 and 10 nm. It is observed that the localized surface plasmon resonance peaks are red-shifted with increasing shell thickness and blue-shifted with increasing core-sizes. Further, broadening in LSPR peaks is found, as the size of core-NiFe NPs increased and optical efficiency increases with Au-shell thickness. The LSPR peaks at λmax show the absorption spectra in the range of 508-541 nm wavelengths and hence, absorption peaks are found in the visible region. In addition, LSPR peaks of NiFe (permalloy) coated with Au NPs are influenced by changing the refractive index of the embedded medium. Hence, the optical response of NiFe coated with Au nanospheres can be tuned and controlled in the visible region of the electromagnetic spectrum. From the results, it is revealed that varying either NiFe-core or Au-shell thickness and embedded medium could result in obtaining tunable light absorption in UV-visible and may find application in optical imaging, sensing, medical, and novel functional and biomagnetic devices. 45

Potty* Centre for Materials for Electronics Technology (C-MET), Scientific Society, Ministry of Electronics & Information Technology, Government of India, Shornur Road, Athani P.O, Thrissur 680 581, India Corresponding author*:[email protected] Plasmonics deals with the study of the interaction of nanometre-scale materials with light, has excellent potential in unique applications such as communication, subwavelength guiding, optical cloaking, etc. Metals such as gold and silver have been conventionally used as plasmonic materials because of the high carrier concentration. Their associated plasma frequency lies in the ultraviolet range. The significant absorption loss at lower frequencies across near-infrared and fixed carrier density of electron of metals forced researchers for alternative materials. The material system, such as conducting metal oxides with low loss and tunable optical properties, is considered as a potential candidate for plasmonic applications in the near-infrared. The response of electrons with photons can be understood on the basis of the dielectric permittivity of materials. The real part of this complex dielectric constant defines the capability of material gets polarized, while the imaginary part indicates the material loss while polarizing. In this study, indium doped zinc oxide thin films were deposited on glass substrate by spin coating (IZO1) and spray coating (IZO2) for low-loss plasmonic applications in near IR. Structural conformation of the films was carried out by XRD. Films deposited at the optimized conditions exhibited a carrier concentration of ~1020/cm3. The zero cross over wavelength of real permittivity was extracted using the dielectric permittivity. The negative real permittivity obtained beyond 2008 nm for IZO1thin film and 2126nm for IZO2 film, which confirmed the plasmonic behaviour of these in the NIR wavelength. The losses calculated for the film are smaller than that of conventional films in the near IR. These films are promising low loss alternative materials to conventional metals for the plasmonic device applications in near IR.

5th National e-Conference on Advanced Materials and Radiation Physics(AMRP-2020) A complete theoretical model is presented in this paper to study the quantum confinement and its effect on optical transitions in a CdS/ZnS core-shell quantum dot. The effect of dot size variation and size distribution on the optical transition in a CdS/ZnS core-shell quantum dot system is discussed in detail. Theoretical calculation reveals the dependency of quantum confinement on shell thickness in a core-shell quantum dot. The study shows a prominent shift in the photoluminescence peak due to change in shell thickness which attributes a change in the depth of conduction and valance band namely band-offset of the core-shell quantum dot system. Our theoretical model can verify reported experimental results successfully which validates our model strongly. NM-09 A Nanophysical Approach to Thermal Transport Ankita R.

Using the Green’s function theory of many body quantum dynamics the relaxation time (linewidth) has been derived to understand the phenomenon of phonon transport through different scattering mechanisms. These scatterings play a vital role to elaborate movement of phonons as well as thermal conduction inside the microfilm with special context of in-plane and cross-plane thermal conductivity. The obtained result shows a fair agreement with experimental observations. The theory explores the possibility of device fabrication with low heat conduction in one direction and high in the other.

Three approaches were pursued by varying two parametric factors: synthesis time and synthesis temperature. The products formed were characterized and analyzed using High Resolution Transmission Electron Microscopy (HRTEM) images. The mechanism involved in the formation of MoS2 along with the changes observed on changing the parametric factors is discussed. The Hall effect measurements give an insight regarding the important transport parameters like resistivity, mobility, type of conductivity and their charge carrier concentration.

NM-12 Hydrothermal Synthesis of Mono/Bi-metallic Nano-particles Anuradha Kashyapb), Partha Bir Barmana) and Surajit Kumar Hazra Department of Physics and Materials science, Jaypee University of Information Technology, Waknaghat, Solan, Himachal Pradesh-173234, India. a)Corresponding author: [email protected], b)[email protected] In this work, Pd, Au and Pd-Au nano-particles were synthesized via hydrothermal approach. The monometallic nano-particles were synthesized by reducing metal precursor sodium tetrachloropalladate and hydrogen tetrachloroaurate for Pd and Au respectively. In bimetallic synthesis both precursors were used simultaneously. PVP was used as a stabilizer which results in the formation of near spherical shaped nanoparticles. The study revealed that the monometallic nanoparticles were smaller in size compared to the bimetallic nanoparticles. A plausible growth mechanism is discussed to understand the difference in the size and shape attributes of the nanoparticles.

The heavy metals contaminated water is of great concern, due do its non biodegradable nature and it can bioaccumulate in the food web which caused serious health risk to humans beings such as cancer, damage of kidney, liver and CNS. Thereforeit is an urgent need to eliminate heavy metals from the water. Several remediation methods which are employed such as ion exchange, electrodialysis, chemical precipitation, adsorption and flotation. Amongst them biosorption is the best method for the removal of heavy metals due to its lower cost and environmentally friendly nature. The efficiency of the biochar can be enhanced by the loading the metal nanoparticle on the surface of biochar. The heavy metals ions adsorbed on the surface of the biochar by different mechanism reduction, surface complexation, co-precipitation, ion exchange and electrostatic interaction.

The molar ratio of aniline and ZnO has an effect on the structural, optical and morphological properties of the nanocomposites. XRD characterization was adopted to gain insight of the change in structural property of the nanocomposites by variation of monomer to metal oxide molar concentration It was found that crystallinity is improved with a decrease of molar amount of aniline. FESEM images depict agglomerated nanowire like structure. The absorption behaviour of the nanocomposites was investigated for the existence of the polaronic band. Peaks at 667 nm show redshift with increase in PAni amount, hence band gap value is found to decrease. Photoluminescence emission spectra initially show enhancement in intensity and later quenching with the increase of polymer content. CIE coordinate is shifted to the deep blue region for a higher amount of aniline in composites. Luminescence property of the nanocomposites has been found to be tuned by the variation of the molar concentration of PAni and ZnO.
