Al-doped ZnO (AZO) is pursued as an alternative low-cost transparent conductive oxide (TCO) to expensive ITO. Atomic layer deposition grown AZO films showing resistivity of 5 × 10−3 Ωcm and transmittance >85% in the visible region are reported. Au-assisted GaAs nanowires are grown directly on an optimized AZO coated g…
Abstract A novel cyclotriphosphazene polymer (PDP) was synthesized by one‐step method with hexachlorocyclotriphosphazene (HCCP) and 4,4′‐biphenol (DOD) as raw materials. The effects of different reaction time and molar ratio of reactants on PDP yield and molecular weight were investigated. The results showed that when…
We report the synthesis of SiC/Si3N4 coatings on carbon/carbon composites via pack cementation and heat treatment with nitrogen gas, the latter of which improves the coating wear resistance. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron…
Regulation of cell-substrate interactions is an important factor for modulating cell behaviors. Tailoring the physical and chemical properties of the substrates to better mimic the extracellular matrix (ECM) of native tissue is a more effective strategy for enhancing the cell-substrate contact. In current work, we aim…
Various polymerase chain reaction- (PCR-) based methods with varying positivity rates were designed to detect the Helicobacter pylori babA2 gene. To compare different primer sets, babA2 prevalence was determined in 279 H. pylori-positive pediatric samples using the 832 bp, 139 bp, and 271 bp PCR primer sets, resulting…
In this work, various reciprocating cycle times of 80, 160, 240, and 320 sec in the diamond wire sawing (DWS) process were adjusted to improve the slicing ability in solar industry. During the same slicing time, the long reciprocating cycle time had less velocity inverse points in comparison with the short reciprocati…
Abstract Poly(ethyl crotonate)s (PECs), possessing various disyndiotacticities, were synthesized by group-transfer polymerization using several silicon Lewis acid catalysts like N-(trialkylsilyl)bis(trifluoromethanesulfonyl)imides (trialkylsilyl = trimethylsilyl, triethylsilyl, tert-butyldimethylsilyl, and triisopropy…
In this study, a novel mechanical‐variable‐flux interior permanent magnet motor (MVF‐IPMM) is presented, which employs rotatable magnetic poles and a mechanical flux‐adjusting device placed on both sides of the rotor. The device can regulate the magnetic circuit by rotating magnetic poles and adjusting the angle of th…
Knowing about metal coating (electroplating) is the electrodeposition of coatings or coatings attached to the electrodes to protect the substrate by giving surface properties and dimensions different from the base metal or finishing technique, by coating metal that is easily corroded (corrosion) with metals that are r…
Abstract In this study, In2O3, Bi2WO6, and cubic heterojunction In2O3/Bi2WO6 were synthesized and characterized by several techniques. Their photocatalytic properties in removal of florfenicol (FLO) antibiotic from aqueous media were evaluated from experimental and theoretical perspectives. The effect of catalyst type…
Flexible and wearable electronics have huge potential applications in human motion detection, human-computer interaction, and context identification, which have promoted the rapid development of flexible sensors. So far the sensor manufacturing techniques are complex and require a large number of organic solvents, whi…
Abstract We have compared the E‐change pulses occurring in the upper positive charge region (UPCR) and the middle negative charge region (MNCR) of 41 normal intracloud (IC) flashes. E‐change pulses can be roughly grouped into isolated pulses and pulse trains with both positive and negative polarities. Although isolate…
Abstract The oxidative polymerisation of catechols in the presence of amino groups is an important reaction leading to polymers or oligomers of great practical importance. We present here, the oxidative polymerisation in the presence of nitro‐substituted aryl hydrazines using ammonium peroxydisulfate (APS) as oxidizin…
The optical band gap of methylammonium lead iodide (CH 3 NH 3 PbI 3 ) is known to increase with temperature; such a dependence is referred to as an unusual behavior when compared to conventional semiconductors. In addition, the band gap exhibits a sharp decrease in a narrow temperature range during the orthorhombic-to…
Abstract Monolayer C 2 N has been successfully synthesized. To explore the enhancement of its stability and the expansion of its potential applications in electronics and optoelectronics, a vertical van der Waals heterostructure is constructed by C 2 N monolayer integrated with h -BN monolayer. The first-principles ca…
Abstract The development of organic nanoagents that integrate diagnosis and therapy has gained considerable attention over the last decades. Here, phthalocyanine‐based nanodots (ZnPc‐NDs) are developed through a facile hydrothermal method. The self‐aggregation of molecules in nanostructures facilitates the fluorescenc…
Tunable elastic interface states in soft materials have been successfully observed in experiments recently, which provides great application potentials in dynamic vibration energy‐harvesting devices or mechanical control of soft robotics. However, the generation of the proposed tunable elastic interfacial states relie…
Lithium-sulfur (Li-S) batteries have been widely studied in recent years, but the utilization of sulfur cathode is still limited by the low conductivity of cathode material and dissolution of polysulfides. A polypyrrole (PPy) coated reduced graphene oxide/S (RGO/S@PPy) material was synthesized in this study. It is sho…
Bioelectrochemical system (BES) exhibits great potential for the wastewater treatment, which can achieve the energy storage simultaneously. However, the application of BES is limited due to the interior structure and composition of electrode materials. Here, a hybrid nano-structure reduced graphene oxide-Mn 3 O 4 (rGO…
The objective of this study was to evaluate the efficiency of glauconitic siltstone as a multi-nutrient source for flooded rice. Two experiments were carried out under greenhouse conditions, one using a Ferralsol and the another an Arenosol. Glauconitic siltstone was applied in different doses (0, 5, 20, 40, and 80 mg…
