*H migration-assisted MvK mechanism for efficient electrochemical NH synthesis over TM-TiNO.

The electrochemical NH synthesis on TiNO is proposed to follow the Mars-van Krevelen (MvK) mechanism, offering more favorable N adsorption and activation on the N vacancy (Nv) site, compared to the conventional associative mechanism. The regeneration cycle of Nv represents the rate-determining step in this process. This study investigates a series of TM (Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, and Pt)-TiNO to explore the *H migration (from TM to TiNO)-promoted Nv cycle.

Promoted photocatalytic N fixation to ammonia over floatable TiO/Bi/Carbon cloth through relay pathway.

The floatable photocatalyst at N-water interface allows the adequate supply of N reactant and the utilization of photothermal energy for photocatalytic N fixation, however, the presence of non-volatile NO product poses a challenge to the stability as it easily covers the catalytic active sites. Herein, a floatable TiO/Bi/CC (Carbon cloth) photocatalyst was designed, in which the non-volatile NO can be transformed to the volatile NH via the newly synergistic relay photocatalysis pathway (N → NO → NH) between TiO (N → NO) and Bi (NO → NH). Attractively, the spontaneous NO → NO step occurs on Bi component to promote the relay pathway performing.

NiRu-MoTiCO as an efficient catalyst for alkaline hydrogen evolution reactions: the role of bimetallic site interactions in promoting Volmer-step kinetics.

The Volmer step in alkaline hydrogen evolution reactions (HERs), which supplies H* to the following steps by cleaving H-O-H bonds, is considered the rate-determining step of the overall reaction. The Volmer step involves water dissociation and adsorbed hydroxyl (*OH) desorption; Ru-based catalysts display a compelling water dissociation process in an alkaline HER. Unfortunately, the strong affinity of Ru for *OH blocks the active sites, resulting in unsatisfactory performance during HER processes.

Synergistic Effect of Co(HPO)(OH) Cocatalyst and AlO Passivation Layer on BiVO Photoanode for Enhanced Photoelectrochemical Water Oxidation.

Bismuth vanadate (BVO) is regarded as an exceptional photoanode material for photoelectrochemical (PEC) water splitting, but it is restricted by the severe photocorrosion and slow water oxidation kinetics. Herein, a synergistic strategy combined with a Co(HPO)(OH) (CoPH) cocatalyst and an AlO (ALO) passivation layer was proposed for enhanced PEC performance. The CoPH/ALO/BVO photoanode exhibits an impressive photocurrent density of 4.

Ultrawide-view achromatic circular polarization dynamic converter using an easy-to-integrate multi-layer structure.

What we believe to be a novel integrated circular polarization dynamic converter (CPDC) is proposed based on the four-layer mirror symmetry structure. By designing the twisted structure and rearranging the orientation direction of liquid crystal molecules for each layer, the application wavelength range could be broadened. For the viewing angle expansion, negative birefringent films are selected to compensate for the retardation deviation under oblique incidence.

Nano-biosensor for SARS-CoV-2/COVID-19 detection: methods, mechanism and interface design.

The epidemic of coronavirus disease 2019 (COVID-19) was a huge disaster to human society. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which led to COVID-19, has resulted in a large number of deaths. Even though the reverse transcription-polymerase chain reaction (RT-PCR) is the most efficient method for the detection of SARS-CoV-2, the disadvantages (such as long detection time, professional operators, expensive instruments, and laboratory equipment) limit its application.

The Effect of Nitrogen Annealing on the Resistive Switching Characteristics of the W/TiO/FTO Memory Device.

In this paper, the effect of nitrogen annealing on the resistive switching characteristics of the rutile TiO nanowire-based W/TiO/FTO memory device is analyzed. The W/TiO/FTO memory device exhibits a nonvolatile bipolar resistive switching behavior with a high resistance ratio (R/R) of about two orders of magnitude. The conduction behaviors of the W/TiO/FTO memory device are attributed to the Ohmic conduction mechanism and the Schottky emission in the low resistance state and the high resistance state, respectively.

Monodisperse MoS/Graphite Composite Anode Materials for Advanced Lithium Ion Batteries.

Traditional graphite anode material typically shows a low theoretical capacity and easy lithium decomposition. Molybdenum disulfide is one of the promising anode materials for advanced lithium-ion batteries, which possess low cost, unique two-dimensional layered structure, and high theoretical capacity. However, the low reversible capacity and the cycling-capacity retention rate induced by its poor conductivity and volume expansion during cycling blocks further application.

Facile preparation of nickel phosphide for enhancing the photoelectrochemical water splitting performance of BiVO photoanodes.

The photoelectrochemical (PEC) water splitting performance of BiVO (BVO), a promising photoanode material, is constrained by its extremely short hole diffusion length and slow water oxidation kinetics. Modification of oxygen evolution cocatalysts (OECs) by appropriate methods is a practical solution to enhance the PEC water splitting performance of BVO. In this work, two different nickel phosphides NiP and NiP were prepared by a facile and mild one-step solvothermal method, and used as OECs to modify a BVO photoanode for enhancing the PEC water splitting performance.

Vanadium nitride nanoparticle decorated N-doped carbon nanotube/N-doped carbon nanosheet hybrids a CN self-sacrificing method for electrochemical capacitors.

Owing to the wide negative potential window (∼1.2 V) along with high specific capacitance (1340 F g) in alkaline electrolyte, vanadium nitride (VN) has been served as promising negative supercapacitor electrode material. However, VN is easy to dissolve during cycling process and shows low capacitance retainability.

This hybrid combines the high conductivity of CNTs and double adsorption of CNTs and NiO (physical and chemical adsorption) to improve the electrochemical performance for the sulfur electrodes.

C3c deposition predicts worse renal outcomes in patients with biopsy-proven diabetic kidney disease in type 2 diabetes mellitus.

Background: Although extensive efforts have been paid to identify reliable predictors for renal outcomes of diabetic kidney disease (DKD) patients in type 2 diabetes mellitus (T2DM), there are still only a limited number of predictive factors for DKD progression. Increasing evidence reported the role of the overactivated complement system in the pathogenesis of DKD. Whether renal complement depositions are associated with renal outcomes of DKD in T2DM is of interest.
