A high current matching over full-swing and low-glitch charge pump (CP) circuit is proposed. The current of the CP is split into two identical branches having one-half the original current. The two branches are connected in source-coupled structure,

Abstract: Dimethyl sulfoxide (DMSO) is not only a common and cheap aprotic polar solvent with low toxicity but also serves as an efficient and multipurpose reactant, and has widely been used in organic synthesis. DMSO as an important precursor can ef

Double hydrothiolation of bis enol ether macrocycles was achieved under photo-mediated conditions. The thiol-ene reactions afford a fully regioselective anti-Markovnikov post-functionalization. Thanks to the use of ethanedithiol as reagent, moderate

Pt supported on CoFe2O4 and NiFe2O4 spinel oxides were much more active for low temperature CO oxidation compared to those supported on monometallic oxides (i.e. Co3O4, Fe2O3 and NiO). The Pt/CoFe2O4 catalyst gave the best performance, with a turnove

Spinal cord injury (SCI) induces aberrant expression of microRNAs (miRNAs), causing various secondary injury responses, including inflammation, apoptosis and oxidative stress. However, the mechanisms underlying miRNA‑mediated apoptosis have not bee

Ankylosing spondylitis (AS) is a common form of seronegative spondyloarthritis. We had identified differentially expressed genes (DEGs) in AS based on our previous RNA-sequencing results. Our study aimed to identify key genes in AS by integrated micr

By the chemical sequential extraction method, various chemical speciation of phosphorus were extracted from shallow sediments of Nansi Lake. Aiming at the existing problems of lower concentration of phosphorus, the method combined the original sequen
