Unraveling Anionic Redox for Sodium Layered Oxide Cathodes: Breakthroughs and Perspectives

Advances in Materials, 2021
Sodium‐ion batteries (SIBs) as the next generation of sustainable energy technologies have received widespread investigations for large‐scale energy storage systems (EESs) and smart grids due to the huge natural abundance and low cost of sodium. Although

Redox Control, Redox Signaling, and Redox Homeostasis in Plant Cells

2003
Redox chemistry is a key feature of life. Oxidized substrates are reduced to synthesize functional molecules; reduced substrates are oxidized for energy supply. In addition, cells must fight against uncontrolled oxidation of essential constituents, a process that continuously occurs in an atmosphere of 21% O2. The redox situation is further complicated

A Comprehensive Review of Materials with Catalytic Effects in Li-S Batteries: Enhanced Redox Kinetics.

Angewandte Chemie, 2019
Use of lithium-sulfur battery (LSB) is an attractive approach to achieve cost-effective and high energy density batteries. However, the insulating nature of active materials, shuttle effect, and slow redox kinetics lead to severe capacity decay and low ...

Redox regulation: an introduction

Physiologia Plantarum, 2004
The redox‐state is a critical determinate of cell function, and any major imbalances can cause severe damage or death. The cellular redox status therefore needs to be sensed and modulated before such imbalances occur. Various redox‐active components are involved in these processes, including thioredoxins, glutaredoxins and other thiol/disulphide ...

Redox signaling

2002
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have recently been shown to be involved in a multiplicity of physiological responses through modulation of signaling pathways. Some of the specific signaling components altered by reactive oxygen and nitrogen species (RONS) have begun to be identified.

Redox Regulation of the Microcirculation

Comprehensive Physiology, 2020
AbstractThe microcirculation maintains tissue homeostasis through local regulation of blood flow and oxygen delivery. Perturbations in microvascular function are characteristic of several diseases and may be early indicators of pathological changes in the cardiovascular system and in parenchymal tissue function.

Catalyse sélective redox

Opérations unitaires. Génie de la réaction chimique, 2013
L'oxydation catalytique joue un role central dans l'industrie chimique, car au cours de la synthese de bon nombre de commodites de tous les jours, au moins une etape dans leur cycle de production est une etape d'oxydation. La catalyse heterogene d’oxydation menagee redox est presentee avec des realisations industrielles et les perspectives pour l ...
