BMEMat, EarlyView.MiR‐29b is enriched in extracellular vesicles (EVs) via a tetraspanin transporter‐dependent endocytosis and sorting complex required for the endosomal transport (ESCRT)‐dependent pathway. These EVs target the 3′ untranslated region (3′UTR) of TGFB2, thereby inhibiting the TGF‐β/Smad3 signaling pathway and repairing endometrial damage in intrauterine ...

Carbon Energy, EarlyView.Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for
