The group of ZHANG Lixin used gene silencing and other techniques to clarify the roles of promoters in Streptomyces secondary metabolite production in S. avermitilis, using lycopene production as a model. Based on a single cell reporter gene (sfGFP) and flow cytometry, a synthetic module of regulatory elements could be designed which activates S. avermitilis gene cluster expression, greatly improving the yield and efficiency of lycopene production.

The team regenerated cellulose by co-dissolving a pore-forming agent resulting in a nanopore, macroporous cellulose sponge matrix which could be used to separate surfactant-stabilized oil-in-water emulsion. Without chemical modification, this sponge had special wetting properties and could be used for oil-air, or underwater applications.

The group of DU Pingwu used a crystalline Ni2P catalyst which anchors semiconductor nanorods. After excited by light, the Ni2P catalyst generates an active electron which reduces water and generates hydrogen. When the system was excited at 450nm, the apparent quantum yield reached ~41%. One milligram material could produce 1200umol hydrogen per hour.

At least 80 % of apps and services available in China were compatible with the Beidou Navigation Satellite System (BDS), an alternative to US-operated GPS. Services based on the BDS are used not only for industrial purposes such as geographic surveying, traffic monitoring and agriculture, but also for car navigation and positioning services on mobile phones. Annual revenue is reported as 134 billion Yuan in 2014. China launched the 18th and 19th BDS satellites in July, for 2020 a complete set of 35 satellites is planned.
