Modeling impairment of ionic regulation with extended Adaptive Exponential integrate-and-fire models.

J Comput Neurosci

January 2025

Paris-Saclay University, Centre National de la Recherche Scientifique (CNRS), Institute of Neuroscience (NeuroPSI), 91198, Gif sur Yvette, France.

To model the dynamics of neuron membrane excitability many models can be considered, from the most biophysically detailed to the highest level of phenomenological description. Recent works at the single neuron level have shown the importance of taking into account the evolution of slow variables such as ionic concentration. A reduction of such a model to models of the integrate-and-fire family is interesting to then go to large network models.

Switching CO2 Electroreduction toward C2+ Products and CH4 by Regulate the Protonation and Dimerization in Platinum/Copper Catalysts.

Angew Chem Int Ed Engl

January 2025

Beijing Institute of Technology, Research Center of Materials Science, School of Materials Science and Engineering, No.5 South Street of Zhongguancun, Haidian District, 100081, Beijing, CHINA.

Copper (Cu)-based catalysts exhibit distinctive performance in the electrochemical CO2 reduction reaction (CO2RR) with complex mechanism and sophisticated types of products. The management of key intermediates *CO and *H is a necessary factor for achieving high product selectivity, but lack of efficient and versatile strategies. Herein, we designed Pt modified Cu catalysts to effectively modulate the competitive coverage of those intermediates.

Rapid Charge Transfer Endowed by Heteroatom Doped Z-Scheme Van Der Waals Heterojunction for Boosting Photocatalytic Hydrogen Evolution.

Small

January 2025

College of Ecology and Environment, Co-Innovation Center for the Sustainable Forestry in Southern China, Nanjing Forestry University, Nanjing, 210037, P. R. China.

Constructing heterojunctions between phase interfaces represents a crucial strategy for achieving excellent photocatalytic performance, but the absence of sufficient interface driving force and limited charge transfer pathway leads to unsatisfactory charge separation processes. Herein, a doping-engineering strategy is introduced to construct a In─N bond-bridged InS nanocluster modified S doped carbon nitride (CN) nanosheets Z-Scheme van der Waals (VDW) heterojunctions (InS/CNS) photocatalyst, and the preparation process just by one-step pyrolysis using the pre-coordination confinement method. Specifically, S atoms doping enhances the bond strength of In─N and forms high-quality interfacial In─N linkage which serves as the atomic-level interfacial "highway" for improving the interfacial electrons migration, decreasing the charge recombination probability.

Diabetes significantly increases the risk of serious health issues, including prolonged skin inflammation and delayed wound healing, owing to inferior glucose control and suppression of the immune system. Although traditional hydrogen (H2) therapy is slightly effective, its ability to tailor the release of H2 on the skin is limited. Accordingly, this study proposed a novel strategy for electrocatalytic H2 release under neutral conditions to promote wound healing in diabetic mice and rabbit.
