Dr. Jangwoo Kim has a resume’ that puts a great many qualifications together that spell “battery designer.”  He has a B.S. degree in chemical engineering from Yonsei University, one of three “Sky Universities” regarded as South Korea’s most prestigious.  At Cornell University, he received M. S. and Ph.D degrees in chemical engineering, and then worked for LG Chem on lithium-ion battery pack design.  After that, he returned to Cornell to work on his Ph.D, investigating “next-generation rechargeable battery technology, including Li-Air and Li-Sulfur, specialized in inorganic nanomaterial synthesis and polymer processing via an electrospraying method.”  He joined IBM Research, Almaden Research Center in 2016 and participated in the Battery 500 project, aiming to build a battery pack with a specific energy …

Twisting, Turning and Nailing the Landing

We like to think that our mastery of aerobatics is second to none, but aircraft only achieve a small part of the birds’ ability to hover, swoop, and perch on a target at zero forward airspeed.  Researchers in Switzerland and England, though, are making progress toward deeper emulation of nature’s masters of flight. Our Fine Feathered Drone Dano Floreano and his team of researchers at  Switzerland’s École Polytechnique Fédérale De Lausanne’s (EPFL) Laboratory of Intelligent Systems, obviously spent lots of time observing birds in flight, noting that our avian friends alter their wing configuration to “change direction, increase their speed or counter headwinds.”  Changing wing shape helps birds make near-instantaneous maneuvers. Floreano, attempting to mimic the birds’ movements, helped develop …
