Single-atom catalysts (SACs) with atomic dispersion active sites have exhibited huge potentials in peroxymonosulfate (PMS)-based Fenton-like chemistry water purification. However, four-N coordination metal (MN 4 ) moieties often suffer from such problems as low selectivity and narrow workable pH. How to construct SACs a controllable strategy optimized electronic structures is of great challenge. Herein, an innovative (i.e., the “4 + 1” fabrication) was devised precisely modulate first-shell...
In this study, isotopic compositions of atmospheric total gaseous mercury (TGM) were measured in the Mt. Changbai (MCB) temperate deciduous forest and Ailao (MAL) subtropical evergreen over a 1-year period. Higher δ202HgTGM values observed under canopy than above MCB forest. The vertical gradients Δ199HgTGM are positively correlated with satellite-based normalized difference vegetation index (NDVI, representing photosynthetic activity), suggesting that strong activity (high NDVI) induces...
Significance In this study, we identify a process that recaptures atmospheric Hg in glacier-retreated areas driven by global warming. Melting of glaciers is known to release originally locked ice into the atmosphere and downstream ecosystems. Recession promotes rapid establishment vegetative ecosystems capture more over long run than released from glacier melting. The increased biomass climate change can result significant changes cycling.
Abstract. Land surface emissions are an important source of atmospheric total gaseous mercury (TGM); however, its role on the variations TGM isotopic compositions and concentrations has not been properly evaluated. In this study, isotope compositions, a powerful tracer for sources transformation Hg, were measured at 10 urban sites one rural site in China. higher summer than winter most cities except Guiyang Guangzhou low latitudes. The summertime high coincided with prevailing δ202Hg Δ199Hg...

Recent advancement in small-molecule as novel probes living cells was also discussed. Keywords: Fluorophore, Synthesis, Fluorescent imaging, Molecular probe, Cellular molecules, Live
This study examined the isotopic composition of particulate bound mercury (PBM) in 10 Chinese megacities and explored associated sources transformation mechanisms. PBM these cities was characterized by negative δ202Hg (mean: -2.00 to -0.78‰), slightly highly positive Δ199Hg -0.04 0.47‰), Δ200Hg 0.02 0.06‰) values. The signatures were likely caused physiochemical reactions aerosols. Δ199Hg/Δ201Hg ratio varied from 0.94 1.39 increased with increase corresponding mean Δ199HgPBM value. We...
An electricity-promoted method for Friedel–Crafts acylation of biarylcarboxylic acids is described in this research. Various fluorenones can be accessed up to 99% yields. During the acylation, electricity plays an essential role, which might motivate chemical equilibrium by consuming generated TFA. This study predicted provide avenue realize a more environmentally friendly process.
Proton transport channels in biological systems are constructed by the specific amino acid residues with hanging carboxylic groups acting as proton donors and acceptors, enabling rapid conduction via Grotthuss mechanism. Hydrogen‐bonded organic frameworks (HOFs) promising candidates for artificially simulating due to their designable structure abundant sources network. However, these protons were usually immobilized within hydrogen bonds between two building blocks, which require a high...
Abstract Modulating the electronic states of active metal sites through microenvironment engineering is a promising strategy for enhancing catalytic performance. However, precise control and stabilization present substantial challenges that require further investigation. Herein, an ionic hydrogen‐bonded organic framework (HOF) incorporating 2,6‐pyridinedicarboxylic acid (PDA) moieties constructed. The rigid tridentate coordination cores generate net dipole moment along metal‐nitrogen axis at...

Manganese‐based layer‐structured oxide materials are considered as one of the most competitive cathode for sodium‐ion batteries due to their low cost and efficient sodium intercalation chemistry. Their electrochemical performance, however, is hindered by mechanical chemical failures stemming from weak interlayer interactions, Jahn‐Teller effect Mn3+ unstable surfaces. To address these issues, a quenching method was employed fabricate robust multiphase structure with fluorine dislocation‐rich...
