IMPACT: From High Technology to Low Technology

Bridging the gap between the energy grid and sources of renewable energy

A team of Ohio State researchers debuted the world’s first solar battery that offers a 20 percent energy savings over traditional lithium-iodine batteries. A solar panel on top and flowing water inside puts this technology in the new class of battery called aqueous flow batteries. Created in the lab of Yiying Wu (chemistry and biochemistry), the technology can be easily integrated with current technologies and could potentially bridge today’s energy grid with sources of renewable energy. The Wu Lab’s ultimate goal is to increase the solar cell’s energy savings to 100 percent, meaning a fully solar-rechargeable battery.

Catching memory problems early

A simple pen-and-paper test created by Douglas Scharre (neurology) is helping people and their medical professionals determine if they are experiencing early signs of dementia. The Self-Administered Gerocognitive Examination (SAGE) test can be taken at home and shared with physicians to help spot early symptoms of cognitive issues such as early dementia or Alzheimer’s disease. Scharre’s SAGE test has been downloaded from Ohio State’s website more than 1.5 million times.
