The excessive use of fossil fuel energy has caused serious environmental problems. Hydrogen (H2) is a clean energy carrier with zero-carbon emission and can be produced by water electrolysis driven by renewable energy, which is beneficial for future global carbon neutrality. Polymer electrolyte membrane (PEM) electrolyzer technology is highly efficient and allows for high hydrogen production rates with current densities up to 2,000 mA cm−2, but suffers from problems of poor stability, high c

Academician He Kebin had on a warm and welcoming smile when we first met for the interview. As the Dean of the Institute of Environment and Ecology (iEE) at Tsinghua Shenzhen International Graduate School (Tsinghua SIGS), he gave off a strong sense of mission, belief, and responsibility as we talked about issues of ecological and environmental protection, discipline construction and talent cultivation.The Tsinghua SIGS iEE was officially established in October 2020. According to the core require

Fish ecosystems perform ecological functions that are critically important for the sustainability of marine ecosystems, such as global food security and carbon stock among others. Without lack of generality, by studying a coastal fish community in Japan, Dr. Convertino (Associate Professor at the Institute of Environment and Ecology) and his former Ph.D. student, Jie Li (now at the University of Amsterdam), investigated the causal effects of fluctuations of sea temperature in fish species

Lithium (Li)-based batteries, particularly Li-ion batteries, have dominated the market of portable energy storage devices for decades. However, the specific energy of Li-ion batteries is approaching their theoretical limit (300 Wh kg-1), making it difficult to satisfy the requirement for long-distance driving with a single charging of electric vehicles.To further increase the energy density of Li-based batteries, the upgrading of electrode and electrolyte materials is urgently desired.

A team of SIGS students competed with six hundred and ninety others at this year’s China Competition on Virtual Reality and won first prize.

The Tsinghua SIGS 2nd International Interdisciplinary Innovation Forum (2021) took place on the morning of October 14th (Beijing time) in a hybrid online and offline format.
