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....
Silicon (Si) has been regarded as next-generation anode for high-energy lithium-ion batteries (LIBs) due to its high Li storage capacity (4200 mA h g−1). However, the mechanical degradation and resultant capacity fade critically hinder its practical application. In this regard, we demonstrate that nanocoating of Si spheres with a 3 nm titanium diox...

Yet some young villagers share the government’s objections to suona funeral performances. To 27-year-old Dong Chengcheng, the funeral reforms are a positive step toward easing the burden on younger generations. “Although the price for booking a suona band is not such a big deal, it still costs money,” he explains. With each funeral typically requiring three days of ceremonies and banquets, the expenses add up — especially as family planning policies have left today’s young people with fewer siblings to share the costs.

On September 19, 2007 Ling was promoted to become Director of General Office of the Communist Party of China, the nerve center of the party that was in charge of all manner of administrative activities of the party's central authorities, including communications and leaders' scheduling and agendas. He also became a Secretary of the Central Secretariat, in charge of the implementation of tasks set forth by the party's Politburo.
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...
