Charge transport channel and nonmetallic plasmon synergistically augment surface reaction kinetics and charge separation for efficient photoelectrochemical hydrogen evolution of CdS/TiN-sensitized FeVO photoanode.

Achieving simultaneous enhancement in the light energy utilization efficiency, bulk charge carrier separation and surface charge carrier injection efficiency as well as the surface reaction kinetics of water oxidation is a formidable challenge for photoanodes in photoelectrochemical (PEC) water splitting hydrogen generation. Herein, nanoparticle-assembled flower-like CdS spheres and nonmetallic plasmonic TiN nanoparticles are exploited to successively sensitize FeVO nanoporous film (NPF) photoanode for achieving efficient PEC hydrogen evolution. The sensitization of TiN and CdS simultaneously integrates type-II band structure, surface plasmon resonance and Schottky junction into FeVO NPF photoanode, synergistically achieving simultaneous enhancement in the light energy utilization efficiency, bulk charge carrier separation efficiency, surface reaction kinetics of water oxidation and surface charge carrier injection efficiency.

Catalytic activation of percarbonate with synthesized carrollite for efficient decomposition of bisphenol S: Performance, degradation mechanism and toxicity assessment.

This study demonstrates the novel application of carrollite (CuCoS) for the activation of sodium percarbonate (SPC) towards bisphenol S (BPS) degradation. The effect of several crucial factors like BPS concentration, CuCoS dosage, SPC concentration, reaction temperature, water matrices, inorganic anions, and pH value were investigated. Experimental results demonstrated that BPS could be efficiently degraded by CuCoS-activated SPC system (88.

Nanolayer-Constructed TiO(OH) Microstructures for the Efficiently Selective Removal of Cationic Dyes via an Electrostatic Interaction and Adsorption Mechanism.

Efficient removal of organic dyes from contaminated water has become a great challenge and urgent work due to increasingly serious environmental problems. Here, we have for the first time prepared nanolayer-constructed TiO(OH) microstructures which can present negative charge by deprotonation of the hydroxyl group to efficiently and selectively remove cationic dyes from aqueous solution through electrostatic interaction and an attraction mechanism. The nanolayer-constructed TiO(OH) microstructures achieve a high adsorption capacity of 257 mg g for methylene blue (MB).

Efficient pollutant degradation under ultraviolet to near-infrared light irradiation and dark condition using CuSe nanosheets: Mechanistic insight into degradation.

The hydrothermally prepared two-dimensional copper selenide nanosheets (2D CuSe NSs) have been employed for the first time to degrade rhodamine B (RhB) in the presence of hydrogen peroxide (HO) under ultraviolet to near-infrared (NIR) light irradiation and dark condition. The experimental measurements demonstrate that 99.7% RhB is degraded under NIR light irradiation for 120 min.

Predictors of Change in Play-Based Communication and Behavior Intervention for High-Risk ASD: The Role of Mother-Child Dyadic Synchrony.

Interindividual variability is important in the evolution of adaptative profiles of children with ASD having benefited from an early intervention make up for deficits in communication, language and social interactions. Therefore, this paper aimed to determine the nature of factors influencing the efficacy variability of a particular intervention technique i.e.

Application of the Still-Face Paradigm in Early Screening for High-Risk Autism Spectrum Disorder in Infants and Toddlers.

Although autism spectrum disorder (ASD) can currently be diagnosed at the age of 2 years, age at ASD diagnosis is still 40 months or even later. In order to early screening for ASD with more objective method, behavioral videos were used in a number of studies in recent years. The still-face paradigm (SFP) was adopted to measure the frequency and duration of non-social smiling, protest behavior, eye contact, social smiling, and active social engagement in high-risk ASD group (HR) and typical development group (TD) (HR: = 45; TD: = 43).

CuO nanoparticles sensitize TiO/CdS nanowire arrays to prolong charge carrier lifetime and highly enhance unassisted photoelectrochemical hydrogen generation with 4.3% efficiency.

Effective separation of charge carriers and substantial prolongation of charge carrier lifetime are two vital issues for a photoanode to achieve highly efficient photoelectrochemical (PEC) hydrogen generation. Herein, a CuO-nanoparticle-sensitized TiO/CdS (TiO/CdS/CuO) nanowire array photoanode is fabricated via subtly combining successive ionic layer adsorption and reaction with a chemical bath deposition method. Both the type-II band alignment with a stair-like structure and a p-n junction are integrated into this ternary photoanode.

Methyl orange adsorption from aqueous solutions on 3D hierarchical PbS/ZnO microspheres.

In this study, three-dimensional (3D) hierarchical PbS/ZnO heterojunction microspheres were successfully fabricated by combining a facile hydrothermal method and an improved successive ionic-layer adsorption and reaction (SILAR). As an adsorbent for the first time, the adsorption activities for the methyl orange (MO) of the prepared 3D hierarchical PbS/ZnO heterojunction microspheres were investigated. By optimizing the loading of PbS nanoparticles (NPs), the 3D hierarchical PbS/ZnO heterojunction microspheres show enhanced adsorption ability for MO with a high removal rate of more than 91% and a maximum adsorption capacity of 159 mg g at equilibrium time within less than 40 min.

['s flying acupuncture for acute cerebral infarction hemiplegia: a randomized controlled trial].

Objective: To compare the efficacy difference between 's flying acupuncture combined with conventional treatment and conventional treatment alone on acute cerebral infarction hemiplegia.

Methods: A total of 120 patients were randomly divided into an observation group and a control group, 60 cases in each one. The control group was treated with conventional treatment, including anti-platelet aggregation, lipid-lowering, formula of traditional Chinese medicine which could promote circulation and remove stasis, neurotrophic medication and symptomatic treatment; mannitol was used for cerebral infarction with large area or increased intracranial pressure.
