and hence the phonon dispersion curves, thermal properties such as lattice specific heat, internal energy, entropy, etc. are of great importance. Recently, the phonon dispersion curves of HfN and ZrN have been obtained using inelastic neutron
considerable research interest to prepare Cs film but the scope of preparing pure Cs film has been largely limited due to the thermal and stability performance of Cs [ 4 – 6 ]. A good thermal property toward the application of Cs in various fields is an
present paper describes the studies on the cure reaction of NADIC/PA modified unsaturated (epoxy) polyesters with styrene initiated by BPO or the mixture of BPO and THPA. Moreover, the thermal properties of copolymers based on those prepared polyesters
coated on the surface of cotton fabrics. The purpose of this research was to investigate the influence of the hybrid coating on thermal properties of cotton fabrics. The characteristics were evaluated through TG, TG-FTIR, and MCC experiments
that higher doses can make this wood specie more susceptible to biological damages. So, the aim of this study is to evaluate the effects of gamma radiation on thermal properties of Pinus ( Pinnus patula and Pinnus cunninghamia ), Cedro
and thermal properties of blends based on PSIA containing 11 or 27 mol% of itaconic acid (PSIA11, PSIA27) and poly( n -butyl methacrylate-co-4-vinylpyridine) containing 26 or 37 mol% of 4-vinylpyridine (PBM4VP26, PBM4VP37) were investigated by various

Abstract
Bi2Te3 nanoparticles (NPs) have been synthesized at 50 °C by a low-cost wet chemical route. The structural properties of product sample were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy. Thermal properties of product sample were investigated by differential scanning calorimetry (DSC), thermogravimetric (TG), and transient plane source techniques. The XRD and selected area electron diffraction of Bi2Te3 NPs result showed the polycrystalline nature with a rhombohedral (R3m) structure of the nanocrystallites. The average grain size of Bi2Te3 NPs was found to be about 30 nm by XRD and TEM measurements. DSC result shows one endothermic peak and one exothermic peak. TG result shows that only 48 % mass loss has occurred in Bi2Te3 sample. The obtained lower thermal conductivity of Bi2Te3 NPs is about 0.3 W m−1 K−1 at room temperature, which is caused by considering the crystalline nature of this material.
