Finally, at 15, Wang’s grandfather allowed him to start his suona training. In addition to practicing on the instrument, every day, he was to blow through a hollow reed into a basin of water to improve his breathing technique. At first, he couldn’t even make bubbles. After a year of practicing for hours each day, his grandfather gave him his first performance opportunity — but stage fright got the best of him.
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....

“It’s quite hard for us to find jobs,” Wang says. “We’re not young, and we don’t have other skills.” When he first started doing short-term construction work earlier this year, he didn’t even know how to mix concrete, but other workers were friendly and helped teach him the basics. He doesn’t mind the labor, though it leaves him sore. He feels his cheeks are stiff after days away from the suona — a reminder that he was once a master musician.
Lanthanum-transition-metal perovskites with robust meso-scale porous frameworks (meso-LaMO3) are synthesized through the use of ionic liquids. The resultant samples demonstrate a rather high activity for CO oxidation, by taking advantage of unique nanostructure-derived benefits. This synthesis strategy opens up a new opportunity for preparing functional mesoporous complex oxides of various compositions.
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
