In this paper, a complete lattice study of thorium telluride (ThTe) in the effects of three-body interaction (TBI) in the framework of RIM and RSM models is reported. By use of the present model, I have theoretically reported elastic constants, pressure derivatives, dispersion relation curve, specific heat curve, combined density of states (CDS) and equation of state of the ThTe compound. The achieved results are good with experimentally reported results and have given very important information about this compound for further investigation. [ABSTRACT FROM AUTHOR]

In this communication, author is presenting ultrasonic and thermophysical properties of potassium fluoride (KF) and potassium chloride (KCl) by van der Waals three body force shell model with the help of second and third order elastic constants at 100 K-300 K. The elastic constants have been calculated by using Coulomb and Born-Mayer potential with the help of two parameters-distance of nearest neighbour and hardness parameter. We evaluated ultrasonic properties such as elastic constants, wave velocities, Debye temperature-average velocity, conductivity, and ultrasonic attenuation due to phonon-phonon interaction along in different direction [100],[110], and [111] orientations. The achieved results are hold good and are given very important information of these crystal for further investigation. [ABSTRACT FROM AUTHOR]

In this article author's are reporting lattice dynamical properties of naphthalene (C10H8) by use of van der Waals three-body force shell (VTBFS) model. we also report the combined density of states (CDS), dispersion relation and elastic properties of naphthalene. So, use of the present model the lattice property of naphthalene is reported successfully.

The unique features and physical properties of the ND4I has given an increased interest in the study of their lattice dynamics by using the present model modified three-body force shell model (MTSM), which includes van der Waals interactions, three-body interactions and second neighbour repulsive interactions into the framework of rigid shell model (RSM). Due to availability of experimental results on dispersion relations, combined density of states (CDS), Debye temperature and elastic property of ND4I has motivated to the author for the theoretical lattice dynamical study of ND4I.A Dispersion curve for translational phonons propagating in the high-symmetry directions of ND4I was determined by the elastic neutron scattering from single crystals. The discrepancies like observed phonon energies with general repulsive short-range forces, second-neighbors discrepancies in the PDC and some other anomalies, we have successfully explained through the present model. The merits of these models have performed with a critical comparison of theoretical and experimental results. [ABSTRACT FROM AUTHOR]

The lattice dynamical investigation of Copper (Cu) has been made on the basis of improved by van der Waals three body force shell models [VTBFSM]. The present model includes van der Waals interactions (VWI) and three-body interactions (TBI) in the framework of both ion polarizable rigid shell models (RSM). van der Waals interactions and three-body interactions in the structure of Rigid Shell model (RSM) with short-range interactions viable up to the second neighbor. In the present communication author has reported thermodynamic properties, dispersion relation and density of state (DOS) of copper by the utilization of the present model [VTBFS] and Phonon-programming. We concentrated on here the lattice dynamics, metal Cu on our approach by figuring phonon dispersion relations along the three principal symmetry directions, entropy, internal energy, free energy, heat capacity at the temperature of 300K and 1356K and density of state (DOS) in THz. The model expectations are sensible for the total harmonic dynamical conduct of the crystals and will concurrence with their experimental reported results. [ABSTRACT FROM AUTHOR]

Applications for nanotechnology, which is constantly gaining prominence, have been found in a variety of industrial applications. Due to the multiple benefits associated with it, including an eco-friendly, pollution-free, cost-effective, and non-toxic synthesis method, the green way to synthesize nanostructures utilizing waste biomasses has become one of the key focuses of the current researches globally. Additionally, lignocellulasic biomass (LCB), which is a waste of the food crops, can be used as one of the potential substrates for the synthesis of a variety of nanostructures. Among different types of LCB, rice straw is a potential food waste biomass and can be efficiently employed during the synthesis of different types of nanostructures for a range of technological applications. Here, diverse phenolic compounds found in rice straw as well as reducing sugars can be used as natural reducing and capping agents to prepare a range of nanostructures. Based on the aforementioned facts, the objective of this review is to investigate the viability of using rice straw to produce nanostructured materials using rice straw as a renewable biosource following an environmentally friendly method. Additionally, it is noted that various organic compounds present on the surface of nanostructures produced using rice straw extract/hydrolyzate through a green approach may be more successful in terms of antibacterial efficacy, which might be of considerable interest for a variety of biomedical applications. Based on the possibility of enhancing the antimicrobial activity of developed nanostructures, the review also provides overview on the feasibility, characteristics, and availability of using rice straw extract in the synthesis of nanostructures.
