A collaborative effort between research groups demonstrates that the physical properties of SrTiO3, or strontium titanate, in its single crystal form can be changed by a relatively simple electrical treatment. SrTi03 is a mineral often studied for its superconducting properties.
Using minute quantities of nanoparticles, or FDA-approved polymer (polyethylene glycol), or higher amounts of sucrose, researchers were able to stabilize vaccines at room temperature for several weeks or, in some cases, months.
Scientists describe a new system to encase chemotherapy drugs within tiny, synthetic nanocarrier packages, which could be injected into patients and disassembled at the tumor site to release their toxic cargo.
It could be a crystal ball from a mythical age showing the swirling mists of time, but this image, which has won this year's Department of Engineering Photography Competition, actually shows graphene being processed in alcohol to produce conductive ink.
