Plants sense and respond to hyperosmotic stress via quick activation of sucrose nonfermenting 1-related protein kinase 2 (SnRK2). Under unstressed conditions, the protein phosphatase type 2C (PP2C) in clade A interact with and inhibit SnRK2s in subgroup III, which are released from the PP2C inhibition via pyrabactin resistance 1-like (PYL) abscisic acid receptors. However, how SnRK2s are released under osmotic stress is unclear.

We investigate a continuous electrochemical pH-swing method to capture CO from a gas phase. The electrochemical cell consists of a single cation-exchange membrane (CEM) and a recirculation of a mixture of salt and phenazine-based redox-active molecules. In the absorption compartment, this solution is saturated by CO from a mixed gas phase at high pH.

Carbon capture and storage (CCS) and CO-based geothermal energy are promising technologies for reducing CO emissions and mitigating climate change. Safe implementation of these technologies requires an understanding of how CO interacts with fluids and rocks at depth, particularly under elevated pressure and temperature. While CO-bearing aqueous solutions in geological reservoirs have been extensively studied, the chemical behavior of water-bearing supercritical CO remains largely overlooked by academics and practitioners alike.

Although microporous carbons can perform well for CO2 separations under high pressure conditions, their energy-demanding regeneration may render them a less attractive material option. Here, we developed a large-pore mesoporous carbon with pore sizes centered around 20-30 nm using a templated technical lignin. During the soft-templating process, unique cylindrical supramolecular assemblies form from the copolymer template.

Antibiotic organic pollutants not only pose a significant threat to human health but also generate a large amount of carbon dioxide (CO) during the treatment process of advanced oxidation processes (AOPs). Herein, the antibiotics aqueous solution was firstly degraded and mineralized by light-assisted peroxymonosulfate (PMS) activation over hollow manganese dioxide (MnO) catalyst and then the corresponding released CO was effectively captured by calcium oxide (CaO) particles in the same sealed reactor, achieving wastewater treatment with zero carbon releasing. Under simulated light conditions, hollow MnO is excited to generate electron-hole pairs.
