Simultaneous greenhouse gas capture and electricity generation marks a paradigm shift from energy-consuming to energy-producing systems

A joint international research team has, for the first time, unveiled the crucial link between the structure of the solid electrolyte interphase (SEI) and the efficiency of lithium-mediated nitrogen reduction to ammonia, a promising eco-friendly approach to fertilizer production. Using in situ spectroscopy, the team directly observed the previously poorly understood SEI formation process, revealing that the ethanol-to-water ratio in the electrolyte significantly impacts ammonia conversion efficiency. This discovery opens a new avenue for sustainable fertilizer production by reducing reliance on fossil fuels and lowering greenhouse gas emissions.

- Professor Choi Jong-min’s research team at DGIST has developed groundbreaking solar cell technology that retains 96.7% of its performance over 140 days and demonstrates high-temperature resistance, thanks to the use of hydrogen-bonding additives. - They discovered that the strong hydrogen-bonding capability of functional additives plays a crucial role in stabilizing the ions that make up perovskite.

Traditional hydrogen peroxide production is energy and emission intensive, and so scientists have sought to synthesize it electrochemically. But tailoring the cobalt-nitrogen-carbon (Co-N-C) catalyst has been challenging. Using a theoretical prediction, which was then experimentally verified, an international research group has designed a Co-N-C catalyst that alleviates this problem.

A research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has presented an external-power-free single-structured PRB, named a dye-sensitized photo-rechargeable battery (DSPB) with an outstanding light-to-charge energy efficiency (ηoverall) of 11.5% under the dim light condition.

A material aims to deliver a one-two punch: recycling atmospheric carbon dioxide for the production of more sustainable hydrocarbon fuels.

DGIST researchers are getting closer to developing a material that delivers a one-two punch: recycling atmospheric carbon dioxide for the production of cleaner hydrocarbon fuels.

A research team led by Tohoku University in Japan has developed new materials for supercapacitors with higher voltage and better stability than other materials. Their research was recently published in the journal Energy and Environmental Science.
