Hydrogels are polymer networks infiltrated with water, widely used for tissue engineering vehicles of drug delivery and novel platforms for biomedical engineering. Emerging applications for new hydrogel materials call for ...
(Phys.org) —Impressive things were happening in physics and the sciences in general last week, starting with a radical new theory from physicists at Griffith University—they are proposing the idea of the existence and ...
Engineers can now capture and predict the strength of metallic materials subjected to cycling loading, or fatigue strength, in a matter of hours—not the months or years it takes using current methods.

(PhysOrg.com) -- Scientists in the US have developed a disposable, non-invasive new biosensor to monitor levels of the stress hormone, cortisol, and say the ultrasensitive electrochemical impedance technique it uses could ...
(PhysOrg.com) -- The normal structure of metals is crystalline. Glass, on the other hand, is amorphous. But it's possible to make amorphous forms of metal, metallic glasses, which can be remarkably strong, having many properties ...
