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...
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.
Several weeks prior to the announcement of the investigation, Ling continued to make appearances on state television in his positions of CPPCC Vice Chairman and United Front chief. On December 15 Ling had penned an article on the Communist theory publication Qiushi brimming with praise for the signature political philosophies of Xi Jinping such as the "Chinese Dream". This was seen by observers as a 'last-ditch' declaration of fealty to the new Chinese leader with whom Ling was thought to have lost favour.
The most successful band in Pingyi County is headed by 29-year-old Liu Ji. In jeans and a tight white T-shirt, with a gleaming stud in his ear, Liu looks the perfect antithesis of Wang, the traditionalist in gray trousers and a loose white shirt. Yet Liu, too, learned to play the suona with a reed and a water basin, he says, practicing through hot summer days until the sweat from his feet soaked prints into the ground. He, too, inherited his band from his family, but he added young acrobats, dancers, singers, and Western instruments.
After Wang took over his grandfather’s band in 2007, he felt immense pressure to sustain the reputation and tradition he had inherited, but prospective clients kept asking for new instruments and styles of music. Eventually, Wang caved, learning the electric keyboard and trumpet and recruiting an opera singer. But work continued to dry up, and Wang now often plays with other bands that have navigated the market more shrewdly.
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 Ferrari 458 Spider accompanied by two women, reportedly of minority ethnic background, who survived. 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. 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.
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....
