The phase evolution and crystal growth of VO <sub>2</sub> nanostructures under hydrothermal conditions was comprehensively investigated and the feasibility of the Ostwald's step rules towards VO <sub>2</sub> polymorph evolution was for the first time demonstrated.
A convenient and efficient method was developed to prepare stable polymer nanoparticles with varied morphology and pH-responsive AIE properties, based on the amphiphilic block copolymer self-assembly, crosslinking, and post-functionalization techniques.
The use of proline-functionalized graphene quantum dots offers the fastest reaction rate and highest yield. The sensor based on the nanohybrid exhibits a higher sensitivity than that of other reported sensors.
In this paper, green synthesis of gold nanoparticles (AuNPs) using leaf extract of Lavender (\nLavandula\nangustifolia\n) and their antioxidant activity was evaluated under the ambient aqueous phase condition. As-\nsynthesized AuNPs were characterized by visual, ultraviolet?visible?near infrared (UV?vis?NIR) spectrosc…
In order to overcome the drawback of traditional photoluminescence materials, which are usually opaque, expensive and non-thermoplastic, a new family of photoluminescence alternate copolymers made from maleic anhydride and different olefin derivatives with very low cost have been developed and are reported in this pap…
Stress–strain curves in three modes (intact, scratched and healed) for; (a) neat epoxy and (b) sample containing 5 wt% microcapsules. SEM micrographs of scratched area of; (c) neat epoxy film, and (d) film with 5 wt% microcapsule.
Sugarcane fibres, in the form of bagasse, are abundant by-products from the sucro-alcohol industry and are commonly used as reinforcement in composite materials. The main objective of this work concerns the modification of the sugarcane bagasse fibers (in natura and pulps rich in cellulose) by benzoylation. Unfortunat…
Solid oxide fuel cell (SOFC) is expected to be a crucial technology in future power generation due to its advantages of high efficiency, fuel adaptability, all-solid state, modular assembly, and low pollution. The Ni/YSZ (yttrium-stabilized zirconia) cermet is the most popular anode material in SOFCs. However, a major…
Using first principles calculations within density functional theory, we investigate multiphase property and phase transition of monolayer MoS2. All the quantities are calculated using the Vienna ab initio simulation package. Calculations are performed within the generalized gradient approximation with van der Waals c…
Multilayer insulation (MLI) is essential for the thermal insulation of cryostat because the apparent thermal conductivity is much lower than that of other vacuum insulation such as evacuated fibrous insulation or powdered insulation. Thermal radiation through MLI is effectively suppressed by thin aluminized polyester…
Various aspects of preparing band-structure-engineered materials involving nanostructured building blocks are examined in this review. In continuation with enjoying great success in controlling the charge carrier transport propertiesof crystalline semiconductors, it was found better to choose a periodic structure comp…
Polypropylene (PP) is a thermoplastic that is used in many applications. Hence, the recycling of PP is very important for the sustainability of the environment. However, the properties of recycled PP (rPP) are lower compared to virgin polypropylene due to the rupturing of its structure during the recycling process. On…
We have revealed experimentally a movement of the topological defects of optical indicatrix orientation, which takes place in CaB 4 O 7 glass with residual mechanical stresses under application of external compressive mechanical stresses. The effect is explained basing on the equation of optical indicatrix perturbed b…

The mass attenuation coefficients and partial interactions of BaO-ZnO-B 2 O 3 glasses have been investigated using WinXCom program at difference photon energy. BaO-ZnO-B 2 O 3 glasses were prepared in composition xBaO: 20ZnO: (80-x)B 2 O 3 (where x = 15 and 20 mol %) by melt quenching technique under normal atmosphere…
To achieve ultrasonic casting of 35 CrMo steel,the waveguide unit for introducing ultrasound into liquid steel was studied numerically and experimentally.The structure and length of the ultrasonic waveguide were optimized by modal analysis.The simulation results showed that a T-shaped waveguide unit matched the vibrat…
0.028%のリンを含有するリン脱酸銅管とリンを含まない無酸素銅管を用いて蟻の巣状腐食発生試験を行った．100，1000，10000ppmのギ酸および酢酸溶液により形成される気相中に，リン脱酸銅管と無酸素銅管を暴露したところ，リン脱酸銅管，無酸素銅管のいずれにも蟻の巣状腐食が発生した．腐食進展速度はリン脱酸銅管のほうが無酸素銅管よりも速かった．一方，全腐食量は無酸素銅管のほうがリン脱酸銅管よりも大きくなった．100，1000ppmのギ酸および酢酸溶液にリン脱酸銅管と無酸素銅管を浸漬する試験においては，酢酸溶液中の無酸素銅管を除き蟻の巣状腐食が発生した．リンを含まない無酸素銅管においても蟻の巣状腐食が発生することから，銅中のリンは蟻…
Представлен обзор современных монокристаллических сплавов на никелевой основе, включая их химический состав, структуру и свойства. Показано влияние легирующих элементов на стабильность структуры, формирование нежелательных фаз и механизм упрочнения, а также редкоземельных элементов – на структуру и высокотемпературные…
Thermally molded commodity plastics become self-healable by the incorporation of heat-resistant and anti-aging healants.
