Microbial-induced Synthesis of nano NiFe LDH for High-efficiency Oxygen Evolution.
Chemistry
January 2025
Wuhan University of Technology - Mafangshan Campus: Wuhan University of Technology, School of Material Science and Engineeringl, CHINA.
NiFe layered double hydroxide (LDH) currently are the most efficient catalysts for the oxygen evolution reaction (OER) in alkaline environments. However, the development of high-performance low cost OER electrocatalysts using straightforward strategies remains a significant challenge. In this study, we describe an innovative microbial mineralization-based method for in situ-induced preparation of NiFe LDH nanosheets loaded on nickel foam and demonstrate that this material serves as an efficient oxygen evolution electrocatalyst.

DNA methylation is a crucial epigenetic modification that orchestrates chromatin remodelers that suppress transcription, and aberrations in DNA methylation result in a variety of conditions such as cancers and developmental disorders. While it is understood that methylation occurs at CpG-rich DNA regions, it is less understood how distinct methylation profiles are established within various cell types. In this work, we develop a molecular-transport model that depicts the genomic exploration of DNA methyltransferase within a multiscale DNA environment, incorporating biologically relevant factors like methylation rate and CpG density to predict how patterns are established.

Bicontinuous particle-stabilized emulsions (bijels) are unique soft materials that combine the bulk properties of two immiscible fluids into a single interconnected structure. This structure is achieved through the formation of two interwoven fluid networks, stabilized by an interfacial layer of colloidal particles. Bijels with submicron-scale domain networks can be synthesized solvent transfer-induced phase separation (STrIPS).

DNA methylation is a crucial epigenetic modification used as a biomarker for early cancer progression. However, existing methods for DNA methylation analysis are complex, time-consuming, and prone to DNA degradation. This work demonstrates selective capture of unmethylated DNAs using ZnO nanowires without chemical or biological modifications, thereby concentrating methylated DNA, particularly those with high methylation levels that can predict cancer risk.

College of Chemistry, International Phosphorus Laboratory, Zhengzhou University, Zhengzhou 450001, P. R. China.
We synthesized a series of polychlorinated trityl radical substituted phenylphosphines. Through UV-vis photoluminescence (PL) spectroscopy and cyclic voltammetry, we explored the influence of the chemical modifications (oxidation/reduction, coordination, and methylation) of the phosphorus center(s) on tuning the optical and redox properties of the tris(2,4,6-trichlorophenyl)methyl (TTM) radical framework. Those compounds hold promise for applications in coordination chemistry and luminescent materials, particularly in systems where both radical and phosphine-based functionalities can be leveraged for innovative properties.
