The oxygen evolution reaction (OER) is of vital importance for electrochemical energy conversion technologies. use metal–organic framework (MOF) catalysts after postprocessing an important method to optimize catalytic activity; however, little attention has been paid the transformation electronic structure and coordinated ions under operando conditions. Here, we focus on a Prussian blue analogue (PBA) with formula Na2Co2+[Fe2+(CN)6]·nH2O at temperature 400 °C. exhibit significant improvement...
Abstract Modulating the coordination environment of metal active center is an effective method to boost catalytic performances metal–organic frameworks (MOFs) for oxygen evolution reaction (OER). However, little attention has been paid halogen effects on ligands engineering. Herein, a series MOFs X─FeNi‐MOFs (X = Br, Cl, and F) constructed with different microenvironments optimize OER activity. Theoretical calculations reveal that increase in electronegativity ions terephthalic acid...
Cu single-atom catalysts are considered as efficient candidates to boost the electrocatalytic CO2 reduction CH4, but source of *H species for CH4 formation during multiple electron–proton transfer process is still elusive. Herein, we reported a facile strategy large-scale preparation via solid-state pyrolysis strategy, with content 3.86 wt %. The single atoms were coordinated by four nitrogen atoms, which allowed accelerate water dissociation form and stabilize key intermediates toward CH4....
Synergistic effects are often used for interpreting the enhanced electrochemical oxygen evolution reaction (OER) activity of catalysts with two or more elements. However, mechanism behind this synergy remains ambiguous. Here, we report an Fe-doped Ni2Mo3O8 (Ni2−xFexMo3O8, where x = 0.1, 0.3, 0.5, 0.7, and 1.0) series high OER (only 196 mV at 10 mA cm−2 0.5) stability over 200 h a current density 500 cm−2. Our in situ X-ray absorption spectroscopies indicated valence-state transition from...
Vitamin D (VD) levels are closely related to the occurrence of post-COVID-19 conditions (PCCs), but specific mechanism is still unclear. Here, a total 50 PCC patient serum samples were divided into VD sufficient group (VD ≥ 30 ng/mL), insufficient (20 ng/mL ≤ < and deficiency 20 ng/mL) then subjected proteomic analysis. We identified 15 differential abundance proteins (DAPs) between groups, including 5 immunoglobulin (JCHAJN, IGHV4–28, GHV4–34, IGHM, IGLV2–11), which significantly negatively...
The global demand for electric power has been greatly increasing because of industrial development and the change in people’s daily life. A lot overhead transmission lines have installed to provide reliable across long distancess. Therefore, research on inspection is very important preventing sudden wide-area outages. In this paper, we propose an Overhead Transmission Line Classifier (OTL-Classifier) based deep learning techniques classify images returned by future unmanned maintenance...
COVID-19 viral infection results in dysregulation of the complement system and a decrease cortisol adrenocorticotropin hormone (ACTH) levels. This study aimed to explore system, as well ACTH responses patients with post-COVID-19 conditions (PCC) type 2 diabetes mellitus (T2DM).
Ion doping is generally an effective strategy for improving the electrochemical performance of electrode materials in protonic ceramic fuel cells (PCFCs). However, specific mechanism by which dopant affects proton transfer remains unclear.

Abstract Electrochemical water‐splitting is vital in energy storage and conversion applications. However, the sluggish kinetics of oxygen evolution reaction (OER) hinders electrochemical water‐splitting. Therefore, developing efficient catalysts understanding OER mechanism are highly desirable.
