Stretchable sensors are attracting more and more attention in conformal electronic devices and wearable electronics. Nevertheless, the fabrication of active flexible sensors with merits of high sensitivity is still a great challenge. Herein, a self-powered stretchable strain sensor is introduced by using PVDF film. Du…
The condition of railroads is the main determinant of train safety. The recent railroads inspection conducted by the mechanic results inaccurate inspection and it cannot be conducted continuously. Therefore, this research develops the inspection by using Image Processing Method. Image processing facilitates and accele…
Warm rolling of medium Mn steel is a promising technology to meet the needs of vehicle weight reduction and energy conservation while ensuring the safety for passengers. In this study, a novel Nb-Mo microalloyed 6.6Mn steel was subjected to a series of warm rolling tests at temperatures ranging from 630 to 690 ºC, bas…
The demand for fuel is increasing every year that the supply comes to decrease. Biodiesel is an alternative energy for diesel fuel. It has the same characteristics as diesel fuel. It also renewable and environmentally friendly. The mixture of biodiesel and diesel fuel lessens the concentration of hydrocarbons and incr…
In this paper, the nanostructured reactive multilayer films (RMFs) are used as the intermediate layer to assist laser welding of Ti6Al4V alloy. During the welding process, the heat of the laser ignites the RMFs, and the heat released by the RMFs reaction instantaneously reaches the liquidus temperature in the center o…
The development of an effective strategy to improve the elastic performance of non-phase-transformation high-entropy alloys (HEAs), as well as the investigation on the effect of metastability on HEAs, is of great significance both practically and theoretically. The structure, morphology and mechanical properties of th…
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging…
The short-stress-path rolling mill is a mechatronics equipment which is widely used in the steel manufacturing industry. China has the largest number of used rolling mills in the world. Most of the rolling mills are served under the harsh environment of high temperature, high humidity and fretting wear, which leads to…
The W-Mo-Cu alloy was rapidly prepared by a large current electric field sintering method at 875-1000℃. Effect of sintering temperature on microstructure, hardness and electrical conductivity was investigated. Based on the dimensional change during alloy sintering, the sintering characteristic index was obtained by fi…
Nano-SiO2 surface grafted APTES (T-SiO2) was realized by covalent functionalization technology, and functionalized nano-SiO2 modified epoxy resin composite (T-SiO2/EP) was prepared. The surface functional groups and chemical elements of the functionalized nano-SiO2were analyzed and the mechanical and tribological prop…
In order to study the nature of interaction between Ba2+ and the KDP crystal surface, the adsorption behavior of Ba2+ on the KDP (100) surface was calculated by using density functional theory (DFT). The results show that the adsorption energies of Ba2+ on the KDP (100) surface are negative, indicating the adsorption…

Synthesis of nanocomposite material, chromium-gadolinium doped with various concentrations of yttrium was investigated for their dielectric properties. Nanocompositional hybrid materials were prepa…
Abstract Electron–phonon (e–ph) interaction in monolayer Janus MoSSe has been investigated using ab initio approach. We find that the asymmetric structure induced net dipole moment in MoSSe introduce an enhanced e–ph interaction compared to the symmetric MoS2. Through the mode resolved scattering analysis, we demonstr…
Abstract Continuous fiber reinforced ceramic matrix composite (CFRC CMC) possessed low density, high temperature resistance, high strength and high toughness, which have been identified as a key and promising military material for replacing the traditional super alloy. CFRC CMC had been used in some hot section compon…
