Abstract As a favorite descriptor, the size effect of Cu‐based catalysts has been regularly utilized for activity and selectivity regulation toward CO 2 /CO electroreduction reactions (CO /CORR). However, little progress made in regulating Cu nanoclusters at atomic level. Herein, size‐gradient from single atoms (SAs) to subnanometric clusters (SCs, 0.5–1 nm) (NCs, 1–1.5 on graphdiyne matrix are readily prepared via an acetylenic‐bond‐directed site‐trapping approach. Electrocatalytic...
Using renewable electricity to synthesize ammonia from nitrogen paves a sustainable route making value-added chemicals but yet requires further advances in electrocatalyst development and device integration. By engineering both electrolyzer simultaneously regulate chemical kinetics thermodynamic driving forces of the electrocatalytic reduction reaction (ENRR), we report herein stereoconfinement-induced densely populated metal single atoms (Rh, Ru, Co) on graphdiyne (GDY) matrix (formulated...
Electrochemical nitrogen fixation under ambient conditions is an attractive prospect to produce ammonia, yet the process still suffers from sluggish kinetics and extremely sensitive structures of catalysts. Metal-free materials with tunable electronic properties represent as alternative catalysts for electroreduction N2. Here, we develop a corrosion engineering strategy that enables heteroatom doping etching host graphdiyne (GDY) simultaneously, leading consequent Cl-doped ultrathin GDY...
Abstract The M‐to‐N 2 π‐backdonation weakens the triple bond of N and shall promote sluggish electrochemical nitrogen reduction reaction (ENRR). By using weak σ‐ π‐donating graphdiyne (GDY) as a supporting material, herein, versatile approach is described to stabilize low‐valence metal single atoms (SA) on GDY (M SA/GDY; M = Cr, Mo, W, Mn, Re). Under rigorous ENRR protocol, an activity trend Re SA/GDY > Mo Cr W >> Mn (no activity) delivered. Theoretical calculations reveal that...

1,2-Dichloroethane (1,2-DCE) is a prevalent environmental contaminant, and our study revealed its induction of testicular toxicity in mice upon subacute exposure. Melatonin, prominent secretory product the pineal gland, has been shown to offer protection against pyroptosis male reproductive toxicity. However, exact mechanism underlying 1,2-DCE-induced comprehensive extent melatonin's protective effects this regard remain largely unexplored. Therefore, we sequenced testis piRNAs exposed...

Chemotherapy is the most common therapeutic strategy for treatment of unresectable hepatocellular carcinoma. However, efficacy limited by low delivery efficiency chemotherapeutics and severe toxicity towards healthy tissues. To address these challenges, active-targeting mesoporous silica nanoparticles conjugating a platinum(iv) prodrug were developed as therapy liver cancer first time. Taking advantage liver-targeting lactobionic acid (LA), smart nano-carriers not only enhanced circulation...

1,2-Dichloroethane (1,2-DCE) is a pervasive environmental pollutant, and overexposure to this hazardous material causes brain edema demyelination in humans. We found that 1,2-DCE inhibits aquaporin 4 (AQP4) primary pathogenic effector of 1,2-DCE-induced animals. However, AQP4 down-regulation's link with cortex after exposure remains unclear. Thus, we exposed wild-type (WT) CD-1 mice knockout (AQP4-KO) 0, 100, 350 700 mg/m3 by inhalation for 28 days. applied label-free proteomics cell...
