Abstract Constructing and manipulating hetero‐interfaces for the electrocatalytic hydrogen evolution reaction (HER) is highly desirable, but still poses a significant challenge. Herein, this work adopts facile way to controllably synthesize three different by anchoring ultrafine Ru nanoparticles on various MoO x nanotube (NT) substrates, including 2 , /MoO 3 . Remarkably, @Ru NT displays excellent HER activity with tiny overpotentials of 89 131 mV delivering large current densities 500 1000...
Abstract Perovskite solar cells (PeSCs) using FAPbI 3 perovskite films often exhibit unfavorable phase transitions and defect‐induced nonradiative interfacial recombination, resulting in considerable energy loss impairing the performance of PeSCs terms efficiency, stability, hysteresis. In this work, a facile interface engineering strategy to control surface structure energy‐level alignment by tailoring between film hole‐transporting layer 4‐hydroxypicolinic acid (4HPA) is reported....
The hybrid structure composed of aluminum alloy and carbon fiber reinforced plastics could combine their advantages. In order to investigate the weldability these two lightweight materials, joints 5052 (AA5052) polyether ether ketone composites (CF-PEEK) were fabricated by friction stir spot welding. variance analysis revealed that dwell time plunge speed most significant factors. By optimizing welding parameters, ultimate tensile shear load reached 2690±64 N (the time: 8 s, speed: 10...
Direct growth of graphene on the metal surface opens a door for obtaining high-performance composites in simple way. In order to obtain both high strength and enhanced damping property porous metal, we prepared graphene-coated nickel hybrid foams by chemical vapor deposition technique investigated static dynamic mechanical properties using analyzer vibration testing systems detail. We found that presence layers could greatly improve foams. The exhibited yield strength, compressive modulus,...
A thermal-state model experimental study was performed in lab to investigate the thermal performance of a wet cooling tower with different kinds filling layout patterns under windless and 0.4 m/s crosswind conditions. In this paper, contrast analysis focused on comparing uniform pattern one kind optimal non-uniform when environmental speed is 0 m/s.

Abstract This study reports a mid‐infrared Ho 3+ :BaY 2 F 8 laser directly pumped by diodes (LDs). A finite element method (FEM) was used to calculate the temperature and thermal stress distributions inside :BYF crystal. The damage conditions have been evaluated on basis of experimental results. Using 889 nm LDs with repetition frequency pulse duration 13 Hz 100 μs, respectively, an output energy 1.05 mJ at 3.9 μm for pump 336.8 achieved. might be useful constructing compact robust laser.

Cotton grafted through crosslinking reaction based on citric acid in presence sodium...
The effects of two types recycled micro-powder (concrete powder and brick powder) replacing part cement on the mechanical properties mortar were studied. results show that contribution concrete to strength is slightly stronger than powder. In a certain range dosage, performance close pure cement. When content less 10 %, compressive flexural will not be greatly affected: over 20% decrease significantly. grinding 5 even increased by 4.5 %. relationship between almost linear limit. more is,...
Abstract Baicalin, an active flavonoid ingredient of Scutellaria baicalensis Georgi, was extracted by heat reflux extraction and showed the same significance UV absorption property with standard baicalin. Active films were prepared from polyvinyl alcohol (PVA) containing baicalin extract casting method.
