Article Abstract
The laccase polymerization of catechol was performed using different reactors namely a water bath (WB), an ultrasonic bath (US) and a high-pressure homogenizer (HPH). The total content of free OH and the MALDI-TOF spectra of polymers obtained demonstrated that reactions are favored in the presence of high-energy environments. Higher conversion yields and polymerization degrees (DP) were obtained after polymerization using US or HPH. Molecular dynamic simulation studies supported these findings by revealing a more open enzyme active site upon environments with high molecular agitation. The higher mass transport generated by US and HPH is the main feature responsible for a higher substrate accessibility to the enzyme which contributed to produce longer polymers.

Alkaline zinc-iron flow batteries (AZIFBs) are one of the promising aqueous redox chemistries for large-scale energy storage due to their intrinsic safety and low cost. However, the energy efficiency (EE) and power density of batteries with low-cost polybenzimidazole (PBI) membranes are still limited due to the relatively poor ionic conductivity of PBI in an alkaline medium. Here, this study proposes a novel chemical approach for regulating the chemical environment of the PBI membrane.

Aqueous batteries have become a prospective future energy storage system because of their low coefficient of cost and stability. However, their lower energy density limits their applications. Ammonium ions (NH) have a small hydration radius and light molar mass, and aqueous ammonium ion batteries (AAIBs) are anticipated for solving the inherent low-energy density problem of aqueous batteries.

The quest for sustainable and clean energy sources has led to significant research into photocatalytic water splitting, a process that converts solar energy into hydrogen fuel. This study demonstrates constructing a high-performance CdTe/CN van der Waals heterojunction for solar-driven water splitting hydrogen evolution. The proposed CdTe/CN heterojunction, investigated using first-principles calculations, integrates favorable structural stability and features a direct bandgap of 1.
