Tungsten Oxide/g-CN Heterostructures: Composition, Structure, and Photocatalytic Applications.

Langmuir

March 2025

School of Material Science and Engineering, University of Jinan, Jinan, 250022, PR China.

The construction of heterostructures promotes extending the light adsorption range of graphitic carbon nitride (g-CN) materials, improving the photogenerated charge carrier separation/transfer efficiency for attaining much enhanced performances. Because defective tungsten oxide (WO) materials possess rich composition/morphology and an extended light response in the near-infrared region, WO is a quite popular nanocomponent for modifying g-CN, forming heterostructures that can be used for various photocatalytic applications involving water splitting, CO reduction, NO removal, HO generation, and related chemical to fuel conversion reactions. In this review, important aspects of WO/g-CN heterostructure photocatalysts are reviewed to provide paradigms for composition adjustment, structural design, and photocatalytic applications of these materials.

Updated Insights Into the Mechanism of Salt-Induced Aggregation-Based Single-Molecule Surface-Enhanced Raman Spectroscopy.

Adv Sci (Weinh)

March 2025

Key Laboratory of Biomedical Information Engineering of Ministry of Education, School of Life Science and Technology, Xi'an Jiaotong University, Xi'an, Shaanxi, 710049, P. R. China.

Since its discovery in 1997, the single molecule surface-enhanced Raman spectroscopy (SM-SERS) has attracted wide interest owing to its enormous potential in many fields. However, the commercialized applications of SM-SERS are still limited by the lack of a clear understanding of the relevant mechanism in the famous SM-SERS experiments. In this study, a salt-gradient model is proposed to deeply investigate the physical nature and update insights into the morphological, structural, and component evolution processes of Ag NPs from dispersed nanostructures to aggregation states in the salt-induced aggregation SERS strategy.

Peripheral nerve injuries (PNIs) often lead to semi or complete loss of motor, sensory and autonomic functions. Although autografts are still the best option for PNI repair, their use is restricted due to the morbidity and availability of donor nerves. Because electrospun scaffolds may replicate the structure of native extracellular matrix (ECM), they provide a viable alternative.

Harnessing intelligence from brain cells in vitro requires a multidisciplinary approach integrating wetware, hardware, and software. Wetware comprises the in vitro brain cells themselves, where differentiation from induced pluripotent stem cells offers ethical scalability; hardware typically involves a life support system and a setup to record the activity from and deliver stimulation to the brain cells; and software is required to control the hardware and process the signals coming from and going to the brain cells. This review provides a broad summary of the foundational technologies underpinning these components, along with outlining the importance of technology integration.

Effects of tea polyphenols disinfectant on microbial communities and potential pathogenic bacteria in water.

Environ Technol

March 2025

Key Laboratory of Urban Stormwater System and Water Environment, Ministry of Education, Beijing University of Civil Engineering and Architecture, Beijing, People's Republic of China.

The structural and abundance changes in water disinfected by tea polyphenols were investigated in high-abundance microbial communities (HAMC), medium-abundance microbial communities (MAMC), and low-abundance microbial communities (LAMC), also included the interactions within and between these communities. The antibacterial effect of tea polyphenols was observed at concentrations of 20-300 mg/L. If the tea polyphenols concentration is greater than or equal to 200 mg/L, it can continue to inhibit the growth of bacteria, and keep the total number of bacteria in 48 hours no more than100 CFU/ml, and this reflected the continuity of tea polyphenols disinfectant in the pipe network.

Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) due to their tunable bandgaps, which allow the active layers to be optimized for artificial light sources. However, significant non-radiative carrier recombination under low-light conditions has limited the full potential of perovskite-based IPVs. To address this challenge, an integration of perylene diimide (PDI)-based sulfobetaines as cathode interlayers (CILs) is proposed and the impact of varying alkyl chain length (from 1,2-ethylene to 1,5-pentylene) between the cationic and the anionic moieties is examined.

Electromagnetic materials with adjustable dielectric and magnetic properties are constantly sought after in electronic and industrial fields. In this study, an innovative strategy that customizes anchored Co-based nanoparticles to optimize the electronic behaviors is proposed for the first time, enabling a controllable and high-efficiency evolution of the macroscopic electromagnetic response of Co-based (C/CoT) nanoplates across the X-ray, light in the solar band and gigahertz band. Specifically, in the gigahertz band, the C/Co and C/CoSe nanoplates with high-power loss capabilities can effectively attenuate and convert electromagnetic energy into heat energy, which not only prevents space electromagnetic radiation but also powers energy for various electromagnetic devices such as thermoelectric generators and microwave actuators.

The crystalline CoP@ amorphous WP core-shell nanowire arrays are oriented grown on the Ni foam (CoP@WP/NF). The amorphous WP shell provides more active sites, and the interface charge coupling accelerates the kinetic of the catalytic reaction, making the CoP@WP/NF catalysts excellent activity. In acidic, only 13 and 97 mV overpotentials are needed to reach 10 mA cm and 100 mA cm, respectively, which are the lowest overpotentials among all reported Transition metal phosphide (TMP) catalysts, of course, much lower than that of the Pt/C catalyst (31 mV at 10 mA cm, 120 mV at 100 mA cm).

Patients with severe hemophilia A (HA) often develop undesired immune responses to therapeutic factor VIII (FVIII) that hamper replacement therapy with FVIII-derived products. The transplacental delivery of two Fc-fused FVIII domains in pregnant HA mice was shown to induce partial FVIII-specific immune tolerance in the offspring. Here, we evaluated whether the transplacental delivery of Fc-fused FVIII (rFVIIIFc) induces complete immune tolerance towards FVIII.

Layered-Hierarchical Dual-Lattice Strain Suppresses NiSe Surface Reconstruction for Stable OER in Alkaline Fresh/Seawater Splitting.

Small

March 2025

College of Materials Science and Engineering, Hunan Joint International Laboratory of Advanced Materials and Technology for Clean Energy, Hunan University, Changsha, 410082, P. R. China.

Transition metal selenides (TMSe) are promising oxygen evolution reaction (OER) electrocatalysts but act as precursors rather than the actual active phase, transforming into amorphous oxyhydroxides during OER. This transformation, along with the formation of selenium oxyanions and unstable heterointerfaces, complicates the structure-activity relationship and reduces stability. This work introduces novel "layered-hierarchical dual lattice strain engineering" to inhibit the surface reconstruction of NiSe by modulating both the nickel foam (NF) substrate with MoN nanosheets (NM) and the NiSe nanorods-nanosheets catalytic layer (NiSe-NiSe-NiO, NSN) with ultrafast interfacial bimetallic amorphous NiFeOOH coating, achieving the optimized NM/NSN/NiFeOOH configuration.
