Abstract Thermoelectric Mg 3+ δ (Sb, Bi) 2 Zintls have attracted significant attention because of their high‐performing, eco‐friendly, and cost‐effective features, but thermoelectric properties still need improvement for application to practical devices. Here an outstanding ZT ≈1.87 at 773 K a high average ≈1.2 in n‐type Y‐doped 3.2 Sb 1.5 Bi 0.49 Se 0.01 are reported, both which rank as top values among the reported literature. First‐principles calculations indicate that substituting site...
Further reducing total nitrogen (TN) and phosphorus (TP) in the secondary effluent needs to be realized effectively an eco-friendly manner. Herein, four pyrite/sawdust composite-based biofilters were established treat simulated for 304 days. The results demonstrated that TN TP concentrations from under optimal hydraulic retention time (HRT) of 3.5 h stable at <2.0 0.1 mg/L, respectively, no significant differences observed between inoculated sludge sources. had low N2O, CH4, CO2 emissions,...

A highly enantioselective synthesis of trisubstituted allenes has been achieved through Cu(I)-catalyzed cross-coupling aryldiazoalkanes and terminal alkynes with chiral bisoxazoline ligands. Alkynyl migratory insertion Cu(I) carbene is proposed as the key step for construction axial chirality.
C–C Bond formation and β-F elimination have been achieved in a Cu(I)-catalyzed cross-coupling reaction of terminal alkynes trifluoromethyl ketone N-tosylhydrazones. The represents an efficient synthesis 1,1-difluoro-1,3-enyne derivatives. Mechanistically, the migratory insertion copper carbene intermediate leads to bond formation, which is followed by C–F cleavage.
A highly efficient and operationally simple palladium-catalyzed formal [4 + 1] annulation reaction has been developed. The is featured by the formation of two different C–C bonds on a carbenic center. It represents concise method for synthesis wide range polycyclic aromatic hydrocarbons (PAHs) 1H-indenes with easily available (trimethylsilyl)diazomethane as carbene source. Metal migratory insertion C(sp2)–H bond activation are proposed key steps in this transformation. further demonstrates...
