Developed Self-Controlling ‘Smart’ Fuel Cell Electrode Material

A Highly Active and Redox-Stable SrGdNi0.2Mn0.8O4±δ Anode with in Situ Exsolution of Nanocatalysts

A research team led by Professor Kang Taek Lee in the Department of Energy Science and Engineering developed electrode material for a new form of high-performance Solid Oxide Fuel Cell (SOFC). Since SOFC, which generates electricity by reacting hydrogen (fuel) with oxygen in the air, emits only water after reaction, is ecofriendly, and has little restrictions in installation place, it is drawing limelight as a new and renewable energy technology that is appropriate for distributed generation . However, it has been difficult to obtain stable supply due to the rapid performance decline of electrode generating power amidst sudden stop and the suspension of fuel supply.

Professor Lee’s team ...

Scientists study the energetic particles behind stunning light show. Scientists have quantitatively confirmed how energetic an auroral breakup can be. Using a combination of cutting-edge ground-based technology and new space-borne observations, they have demonstrated the essential role of an auroral breakup in ionizing the deep atmosphere. The research furthers our understanding of one of the most visually stunning natural phenomena.

Auroras, also known as Northern or Southern lights depending on whether they occur near the North or South Pole, are natural displa...

High intake of Dietary Fiber and Whole Grains associated with reduced risk of non-communicable diseases

Image result for High intake of dietary fiber and whole grains associated with reduced risk of non-communicable diseases

Carbohydrate quality and human health: a series of systematic reviews and meta-analyses
January 10, 2019DOI: https://doi.org/10.1016/S0140-6736(18)31809-9

Observational studies and clinical trials conducted over nearly 40 years reveal the health benefits of eating at least 25g to 29g or more of dietary fiber a day, according to a series of systematic reviews and meta-analyses. People who eat higher levels of dietary fibre and whole grains have lower rates of non-communicable diseases compared with people who eat lesser amounts, while links for low glycaemic load and low glycaemic index diets are less clear...

Molecular Insights into Spider Silk


This is a schematic scheme of a spidroin consisting of an assembled C-terminal domain (cyan), the unfolded central domain (white line) and the N-terminal domains (green). Right hand side: scheme of a tapering spinning duct.

Spider silk belongs to the toughest fibers in nature and has astounding properties. Scientists have now discovered new molecular details of self-assembly of a spider silk fiber protein. They are lightweight, almost invisible, highly extensible and strong, and of course biodegradable: the threads spiders use to build their webs. In fact, spider silk belongs to the toughest fibres in nature. Based on its low weight it even supersedes high-tech threads like Kevlar or Carbon...
