This study is focused on the preparation and performance of a building energy storage panel (BESP). The BESP was fabricated through a mold pressing method based on phase change material particle (PCMP), which was prepared in two steps: vacuum absorption and surface film coating. Firstly, phase change material (PCM) was incorporated into expanded perlite (EP) through a vacuum absorption method t...
High-performance piezoelectrics are lead-based solid solutions that exhibit a so-called morphotropic phase boundary, which separates two competing phases as a function of chemical composition; as a consequence, an intermediate low-symmetry phase with a strong piezoelectric effect arises. In search for environmentally sustainable lead-free alternatives that exhibit analogous characteristics, we ...
– We investigate how the normal energy transport is realized in one-dimensional quantum systems using a quantum spin system. The direct investigation of local energy distribution under thermal gradient is made using the quantum master equation, and the mixing properties and the convergence of the Green-Kubo formula are investigated when the number of spin increases. We find that the autocorrela...
Ahstraet -A mathematical model for healing tendon was developed refkcting correlations of biomlchanical and biochemical factors. The model provided values for the physical and mechanical property changes during isometric thermal denaturation utilizing differences associated with treatment and length of healing period, along with the selected biochemical covariates of hydroxyprobne, protein, and...

In the present article, the thermal analysis of the cylinder and the piston in four-cylinder engines, made of functionally graded materials (FGMs), has been performed by using the super element method. The objective of using FGMs in the cylinder and the piston is to increase their performance. FGMs include a combination of ceramics and metals. Inside the cylinder, the ceramic is considered and ...
Future gravitational-wave detectors operated at cryogenic temperatures are expected to be limited by thermal noise of the highly reflective mirror coatings. Silicon nitride is an interesting material for such coatings as it shows very low mechanical loss, a property related to low thermal noise, which is known to further decrease under stress. Low optical absorption is also required to maintain...
In this work, the influence of crystallographic texture on mechanical properties was investigated by X-ray diffraction in the superelastic Ti-24Nb-4Zr-8Sn alloy. Different textures were obtained by changing the cold rolling reduction rate and the following thermal treatment (solution treatment or flash thermal treatment). The tensile tests performed show that Young’s modulus, elongation at rupt...
