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....
Heterogeneous catalysis with core-shell structures has been a large area of focus for many years. This paper reviews the most recent work and research in coreshell catalysts utilizing noble metals, specifically gold, as the core within a metal oxide shell. The advantage of the core-shell structure lies in its capacity to retain catalytic activity u...
Throughout Hu Jintao's leadership, Ling accompanied Hu on trips abroad and was often seen with Hu on inspection visits around the country. As one of Hu Jintao's closest associates and most trusted advisors, in addition to being of an appropriate level of seniority, Ling seemed long destined for higher office. Ling's political fortunes, however, took an abrupt turn in 2012. On March 18, Ling's only son, then 23-Year old Ling Gu, was involved and killed in a car crash on Beijing's 4th Ring Road while driving a black[1] Ferrari 458 Spider accompanied by two women, reportedly of minority ethnic background, who survived.[5] Ling Gu was said to have been found naked, and the women were described as either naked or otherwise "scantily clad," which seemed to suggest sexual activity while driving.[6] While this account was later disputed, the widely discussed "Ferrari crash" was juicy tabloid fodder and exacerbated public cynicism over the debauchery and conspicuous consumption often associated with children of the Communist ruling elite.[7]
When England became an empire, English began borrowing less and became the prolific word lender it is today, Haspelmath told me. If we start borrowing again—the way Arabic stopped exporting words to the rest of the world once its empire crumbled and started borrowing more from French and English—we’ll know we’ve seen the apex of our cultural influence. Until then, at least we’ll be able to find a hot yoga class just about anywhere in the world.
CO oxidation is an important reaction both experimentally and industrially, and its performance is usually dominated by the surface charge state. For example, CO oxidation on platinum (Pt) surface requires a proper charge state for the balance of adsorption and activation of CO and O2. Here, we present a “Mott−Schottky modulated catalysis” on Pt na...
THERE’S NOTHING LIKE visiting Finland to make an English-speaker appreciate the value of words borrowed from other languages. Finnish, as I learned during a trip earlier this month, is an agglutinative language, in which parts of words stay distinct instead of fusing together. This makes for very long words, like “kahdenneksikymmenenneksiyhdeksänneksi” (one way to say “29,” according to my guidebook), and considerable bewilderment for a visitor. To me, it might as well have been Klingon, only with more umlauts. Every now and then, though, a light would shine through the darkness: I’d catch something like “hot jooga” or “muffensi” or “grill maisteri,” and sigh with relief.

Monodisperse cobalt (Co) nanoparticles (NPs) were synthesized and stabilized against oxidation via reductive annealing at 600C. The stable Co NPs are active for catalyzing the oxygen evolution reaction (OER) in 0.1 M KOH, producing a current density of 10 mA/cm2 at an overpotential of 0.39 V (1.62 V vs. RHE, no iR-correction). Their catalysis is s...
