DURING our work on the available thermionic emission from mixtures of the alkaline earth oxides (barium, strontium and calcium oxides), we have studied the properties of the system barium ...

A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific ...

Solid oxide fuel cells (SOFCs) have great potential for stationary and mobile applications. Stationary use ranges from residential applications to power plants. Mobile applications include power for ...

What Is an Upper GI Series? An upper GI series is a group of X-ray tests that look at your GI tract -- your food pipe (the esophagus), stomach, and the first part of your small intestine (the duodenum ...

(Left) ZT of all four cobalt oxide films increases with increasing temperature. The barium cobalt oxide film (red diamonds) has the highest ZT among the four, reaching a high ZT value of ~0.55 at 600 ...

An air contrast barium enema is a test for your colon. These days, doctors don’t use it as often to look for colorectal cancer. Instead, it’s more common to get a colonoscopy, which can find smaller ...
