Upside-Down Rivers of Warm Ocean Water Threaten Stability of Floating Ice Shelves in Antarctica

“Upside-down rivers” of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder’s National Snow and Ice Data Center. The study highlights how parts of Antarctica’s ice sheet may be weakening due to contact with warm ocean water.

Fairchild’s 1200V SiC Diode for Next-Generation Solar Inverters, Industrial Motor Controls and Welders

Fairchild, a leading global supplier of high-performance semiconductor solutions, released its first 1200V silicon carbide (SiC) diode, the FFSH40120ADN, in its series of upcoming SiC solutions. The 1200V diode’s combination of superior switching performance, higher reliability and low electromagnetic interference (EMI) make it ideal for next-generation solar inverters, industrial motor controls and welders which are all increasingly required to be more energy efficient at higher power densities.

NASA Scientists Study Influence of Tidal Movements on Antarctic Ice Shelves

Ice shelves, the floating extensions of the Antarctic and Greenland ice sheets, are not simply resting on the ocean waters: they rise, fall and bend with the tides. Ultimately, these oceanic motions impact the flow of ice coming from the glaciers that these ice shelves buttress. Ryan Walker and Christine Dow, researchers with the Cryospheric Sciences Laboratory at NASA Goddard Space Flight Center in Greenbelt, Maryland, recently spent more than a month doing fieldwork in Antarctica to study the influence of tidal movements on a small, little-studied ice shelf.

POSTECH Research Team Creates Miniaturized Solid Oxide Fuel Cell

Drones are used for various applications such as aero picturing, disaster recovery, and delivering. Despite attracting attention as a new growth area, the biggest problem of drones is its small battery capacity and limited flight time of less than an hour. A fuel cell developed by Prof. Gyeong Man Choi (Dept. of Materials Science and Engineering) and his research team at POSTECH can solve this problem.
