TL;DR: A novel KOAc-promoted α-position C-H activation and alkynylation of ethers with alkynYL bromides to 2-alkynyl ethers has been developed under transition-metal-free and simple reaction conditions.

TL;DR: A novel copper-catalyzed direct α-ketoesterification of propiophenones with acetophenones via C(sp(3))-H oxidative cross-coupling was developed, utilizing O2 as a clean oxidant with high atom economy.

TL;DR: In this article, a double network scaffold was made by poly(2-hydroxyethyl methacrylate) and modified gelatin to facilitate cell behavior on the hydrogels.

TL;DR: Further explorations of the catalytic potential of the dinuclear carbene palladium complexes as catalysts for the Pd-catalyzed transformations have been performed under microwave irradiation conditions, and the complexes exhibited moderate to good catalytic activity in the Hiyama coupling reaction of trimethoxyphenylsilane with aryl chlorides.

TL;DR: In this paper, the authors analyzed the annual and seasonal variability in precipitation and temperature during 1960-2016 using monthly data from 25 national meteorological stations in the Qilian Mountains and found that precipitation increased by 6.2, 4.1, and 8.9 mm/decade for the whole regions, oasis, and mountains, respectively.
