Enhanced Fertilizer Additions Impose Detrimental Effects on Bryophytes[Aug 30, 2016]

Prof. LIU Wenyao and his team of Xishuangbanna Tropical Botanical Garden (XTBG) carried out a manipulative experiment in a subtropical montane cloud forest in the Ailao Mountains National Nature Reserve (23° 36′–24° 56′ N 100° 44′–101° 30′ E). They hypothesized that N fertilization had adverse impacts on physiological performance of epiphytic bryophytes, whereas the combined fertilization with P and S would mitigate the physiological stresses induced by excessive N.

Scientists Uncover Formation Mechanism of Environmentally Persistent Free Radicals in PAHs-contaminated Soil[Aug 30, 2016]

EPFRs have been detected in PAHs-contaminated soil under ambient environmental conditions. A research team led by Prof. WANG Chuanyiat at Xinjiang Technical Institute of Physics and Chemistry (XTIPC) of Chinese Academy of Sciences found the formation mechanism of EPFRs induced by PAHs on Fe3+-clay surface. This work, for the first time, provides experimental evidence for EPFRs formation on the PAHs-contaminated soil under environmentally relevant conditions.

Researchers Develop Sunlight-sensitive MnO2/C Composite Catalyst to Degrade Herbicide[Aug 29, 2016]

According to previous studies, it is necessary to effectively decontaminate the GP residue to lower its environmental impact. Given this, a study team led by Professor WU Zhengyan in Institute of Technical Biology and Agriculture Engineering, developed an alternative MnO2/C composite catalyst based on KMnO4 and graphite using high energy electron beam (HEEB). irradiation.

Researchers Identify Novel Electronic Structure in CaFeAsH-based Superconductors[Aug 29, 2016]

Recently, in order to uncover the novel electronic structure of hydride superconductor CaFeAsH, Prof. ZOU Liangjian in the Key Laboratory of Materials Physics, Institute of Solid State Physics (ISSP), Hefei Institutes of Physical Sciences, join hands with Prof. Warren Pickett from the Department of Physics, University of California Davis, USA to investigate the electronic and magnetic properties of CaFeAsH using the first-principle method and analytical method.
