Researchers Review Technical Solutions for Safe Utilization of Heavy Metal-polluted Farmland in China[Jun 24, 2019]

Dr. LI Xiaofang from the Centre for Agricultural Resources Research, Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences proposed two criteria for evaluating candidate technologies, particularly the metal immobilizers to formulate a responsible technical scheme.

Scientists Determine Bremsstrahlung Emission for Thermal Feature in GRB 130925A X-Ray Afterglow[Jun 24, 2019]

Researchers from Yunnan Observatories of the Chinese Academy of Sciences proposed that bremsstrahlung radiation in a metal-rich and dusty environment can be one possible mechanism to explain the thermal component above 10 keV in X-ray afterglow by theoretically analysing the origin of the thermal X-ray emission of ultral-long gamma-ray burst (GRB) source- GRB 130925A.

Researchers Reveal the Historical Trajectories of China's Water Scarcity[Jun 24, 2019]

Dr. ZHOU Xinyao at the Center for Agricultural Resources Research, together with her colleagues, analyzed the trend of water scarcity and quantified the impact of upstream water use on downstream water scarcity for the past 50 years over China's 12 large basins by reconstructing natural surface runoff and comparing with observed runoff.

Researchers Reveal Role of Autophagy in Glucocorticoid-Induced BAT Whitening[Jun 24, 2019]

A study led by Prof. GUO Feifan from the Shanghai Institute of Nutrition and Health revealed that autophagy inhibition prevents glucocorticoid-increased adiposity via suppressing brown adipose tissue whitening. Glucocorticoids (GCs) are a class of steroid hormones and exert effects by binding to the glucocorticoid receptor.

Defect Repairing Reveals Enhanced Nonlinear Optical Properties of Monolayer[Jun 18, 2019]

Recently, a study led by Prof. WANG Jun from Shanghai Institute of Optics and Fine Mechanics investigated the effect of bis-(trifluoromethane) sulfonimide (TFSI) treatment on the nonlinear optical properties of monolayer S-based transition metal dichalcogenides (TMDs) and found that the TFSI-treated MoS₂ and WS₂ showed enhanced two-photon absorption (TPA) and two-photon luminescence (TPL) performances compared to the untreated counterparts.
