Over the recent decades, China experienced several emerging virus outbreaks including those caused by the severe acute respiratory syndrome- (SARS-) coronavirus (Cov), H5N1 virus, and H7N9 virus. The SARS tragedy revealed faults in China's infectious disease prevention system, propelling the Chinese government to enact reforms that enabled better combating of the subsequent H1N1 and H7N9 avian flu epidemics. The system is buttressed by three fundamental, mutually reinforcing components: (1) enduring government administration reforms, including legislation establishing a unified public health emergency management system; (2) prioritized funding for biotechnology and biomedicine industrialization, especially in the areas of pathogen identification, drug production, and the development of vaccines and diagnostics; and (3) increasing investment for public health and establishment of a rapid-response infectious diseases prevention and control system. China is now using its hard-gained experience to support the fight against Ebola in Africa and the Middle East Respiratory Syndrome in its own country.

Ag/Ag4V2O7 nanocomposites with Ag nanoparticles supported on Ag4V2O7 nanorods have been synthesized with the assistance of sodium dodecyl sulfate (abbreviated to SDS) by a facile one-step hydrothermal reaction and perform high photoelectrochemical response. Ag4V2O7 nanorods are pointed at both ends with an average width of ca. 200 nm. Ag nanoparticles are formed in-situ on the surfaces of the Ag4V2O7 nanorods. The crystal structures and morphologies of samples are affected significantly by the SDS concentration and hydrothermal reaction time. The possible crystal growth process of Ag/Ag4V2O7 nanocomposites induced by SDS has been discussed preliminarily.
