In order to further improve the photocatalytic performance of the SiO2/TiO2 composite under visible light irradiation, curcumin-doped SiO2/TiO2 nanocomposites were synthesized via directly incorporating it into the structure of SiO2/TiO2 during the synthesis using an inexpensive and readily available natural pigment (…
Oxide-based memristive devices have recently been proposed for various applications, such as next-generation memory and neuromorphic devices. Microstructural alterations depending on the oxygen ion concentration, such as the formation of conductive filaments and interface reactions, have been posited as the operating…
Abstract Silver-bismuth-iodide (Ag-Bi-I) semiconductors have increasingly gathered much attention as an alternative to lead halide perovskites. However, Ag-Bi-I has not been thoroughly investigated owing to the complexity in its composition and solution process, and the power conversion efficiency (PCE) of its solar c…
In this work we present a method to quantitatively measure the optical absorption of single nanowires that can be applied over a wide range of temperatures and with a high enough sensitivity to enable the measurement of below-band-gap absorption (as well as the absorption of single molecules). The method is based on a…
Metal nanowire networks are promising materials to replace metal oxide films in transparent conductive electrodes (TCE), but they suffer from low stability in actual working conditions. Here, carbon nanotube/copper (CNT/Cu) composite fibers were fabricated via electrospinning for the first time to address this problem…
Moderator temperature coefficient (MTC) and fuel Doppler temperature coefficient (DTC) are both the key reactivity coefficients for the safety assessment of a nuclear fission reactor core. Conventional unidirectional perturbing computation exhibits a limited scope in understanding the full-core physics. To better assi…
Nano-BiOBr photocatalysts were successfully prepared by Microwave method using ethylene glycol solution. The nano-BiOBr photocatalysts were characterized and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS), and the degradation ability…
More electric aircrafts (MEA) recently attracts increasing attention due to improvements to efficiency, reduce weight, fuel cost, and carbon emissions. High-specific-power machines, and corresponding integrated motor drives have been identified as the crucial enabling technology for the realization of more electric ai…
Abstract The Pt–Fe2O3 nanoparticles embedded over N, P-doped carbon (Pt–Fe2O3/NPC) was successfully synthesized by chemical reduction method demonstrating an enhanced electrocatalytic efficacy in alkaline media toward oxygen reduction reaction (ORR). The surface morphology of Pt–Fe2O3/NPC has been characterized by ele…
Cement-stabilized macadam is an important highway construction material. To fully understand the reinforcing and toughening functions of fibers in cement-stabilized macadam, the influence of the concentration and length of polyvinyl alcohol (PVA) fibers on the performance of cement-stabilized macadam was investigated.…
After the implementation of the ultra-low emissions regulation on the coal-fired power plants in China, the problem of the excessive ammonia-slipping from selective catalytic reduction (SCR) seems to be more severe. This paper analyzes the operating statistics of the coal-fired plants including 300 MW/600 MW/1000-MW u…
The rotation of micropolar thermoelastic solid with temperature-dependent properties on micropolar material affected by the magnetic and gravity was investigated. The Green–Naghdi (G-N) theory of type II was employed to investigate our problem analytically. It is shown that there exist four reflected plane waves due t…
In the present work, SnO2 was successfully coated on mild steel (MS) by the sol–gel method at different times (15,30,45 min). These coatings were developed to improve the performance of corrosion protection of MS in a 0.5 M HCl solution. The morphological and structural characterization of obtained electrodes was inve…
Human being exposed to naturally occurring ionizing radiation throughout their lives as these radionuclides are present in different amounts in our environment. Gamma radiation emitted from uranium (U), thorium (Th), radium (Ra), potassium (K) and cesium (Cs) radionuclides and their decay products represents the essen…
Abstract All-optical modulation with two-dimensional (2D) layered materials are becoming an indispensable tool in a variety of applications due to their superior performance in photonics and optoelectronics.

The phase composition and crystal structure of the synthesized material were investigated using electron diffraction, Raman spectroscopy, and trans…
Abstract For many materials, plastic deformations under cyclic loadings differ from monotonic loading. Cyclic plastic zone with considering the strain hardening effects becomes complicated during unloading step. In this research, the effects of nonlinear kinematic and isotropic hardening behaviours on the cyclic plast…
Methylammonium lead halide ( M A P b I 3 ) is widely used as perovskite absorber material in thin-film solar cell technology because of its eminent cell performance. Recently, formamidinium lead iodide perovskite ( F A P b I 3 ) has received great attention because of its optimum bandgap value closer to the infrared s…
The conventional mechanical design approach of cooling jackets serves the goal of heat dissipation to keep motor temperature below the maximum allowable limit for thermal protection. However, the desired motor performance cannot be effectively achieved by this approach since it only employs heat transfer mechanism. Th…
Atropisomerism is a fundamental feature of substituted biaryls resulting from rotation around the biaryl axis. Different stereoisomers are formed due to restricted rotation about the single bond, a situation often found in substituted porphyrins. Previously NMR determination of porphyrin atropisomers proved difficult,…
