Researchers Design Broad-Range Luminescent Boltzmann Thermometer

Luminescent thermometers become progressively essential for remote, non-invasive temperature sensing at particularly small lateral dimensions, as contact-based detection methods only function in a partial way or even not at all. Standard application areas are temperature recording on catalytic surfaces or in biomedical procedures.

UH Researcher Develops New Fluid that can be Cut Open by Light

Jiming Bao, professor of electrical and computer engineering at the University of Houston, has developed a new fluid that can be cut open by light and demonstrated macroscopic depression of ferrofluid, the kind of fluid that can be moved around with a magnet.
