Unassisted Switchable Dual-Photoelectrode Devices Utilizing p-n Carbon Quantum Dots as "Semiconductor Electrolytes": Optimization Between HO and Solar Electricity Production.

Switchable self-driven photoelectrochemical (PEC) devices are developed to boost HO or electricity generation under visible-light illumination, in which p-n type carbon quantum dots (N-CQDs) is applied as conceptually-new "semiconductor electrolytes". The N-CQDs contains N-dopants, and both negatively- and positively-charged surface groups. This allows N-CQDs to act as the electrolyte and to interact with both a BiVO photoanode and a CuO photocathode.

Microglia modulate integrity of myelin and proliferation of oligodendrocyte precursor cells in murine model of bone cancer pain.

Cancer pain, a frequent complication in patients with cancer, adversely affects quality of life and survival rates. Microglia promote nociceptive information transmission by modulating myelin integrity during pain perception. However, the specific mechanisms by which microglia regulate myelin in the context of cancer pain remain poorly understood.

[Status quo of ED-related studies in China: A bibliometric analysis].

Objective: To summarize and visualize the status quo, future hotspots and development trend of ED-related researches in China through bibliometric analysis.

Methods: We searched the Web of Science Core Collection (WOSCC) and the database of Chinese National Knowledge Infrastructure (CNKI) for ED-related studies published in China from January 1, 2010 to August 14, 2023. Using the CiteSpace and VOSviewer softwares, we bibliometrically analyzed and visualized the related journals, regions, institutions, authors, key words, co-citations and other indexes of the identified studies.

Gradient Lithium Ion Regulation Current Collectors for High-Performance and Dendrite-Free Li Metal Batteries.

Lithium metal anode has attracted wide attention due to its ultrahigh theoretical specific capacity, lowest reduction potential, and low density. However, uncontrollable dendritic growth and volume change caused by uneven Li deposition still seriously hinder the large-scale commercial application of lithium metal batteries, even causing serious battery explosions and other safety problems. Hence, gold nanoparticles with a gradient distribution anchored on 3D carbon fiber paper (CP) current collectors followed by the encapsulation of polydopamine (PDA) (CP/Au/PDA) are constructed for stable and dendrite-free Li metal anodes for the first time.

Heterologous expression of a deacetylase and its application in L-glufosinate preparation.

With potent herbicidal activity, biocatalysis synthesis of L-glufosinate has drawn attention. In present research, NAP-Das2.3, a deacetylase capable of stereoselectively resolving N-acetyl-L-glufosinate to L-glufosinate mined from Arenimonas malthae, was heterologously expressed and characterized.

MicroRNA-based regulatory mechanisms underlying the synergistic antioxidant action of quercetin and catechin in HO-stimulated HepG2 cells: Roles of BACH1 in Nrf2-dependent pathways.

The microRNA-based mechanisms underlying the antioxidant action(s) of co-existing flavonoids in response to oxidative stress are of high interest. This study aimed to extend the existing knowledge and provide insights into the potential regulatory network in response to oxidative stress and the co-presence of quercetin and catechin antioxidants, via a preclinical approach using HO-stimulated HepG2 cells. It was confirmed that BACH1 serves as an essential and direct negative regulator of the Keap1-Nrf2 signaling pathway and the antioxidant synergism between quercetin and catechin.

Three-Dimensional Simulation of DRIE Process Based on the Narrow Band Level Set and Monte Carlo Method.

A three-dimensional topography simulation of deep reactive ion etching (DRIE) is developed based on the narrow band level set method for surface evolution and Monte Carlo method for flux distribution. The advanced level set method is implemented to simulate the time-related movements of etched surface. In the meanwhile, accelerated by ray tracing algorithm, the Monte Carlo method incorporates all dominant physical and chemical mechanisms such as ion-enhanced etching, ballistic transport, ion scattering, and sidewall passivation.
