Visible Light Absorption of Titanium Dioxide Through Cerium Synchronous Doping in Anatase The introduction of rare earth elements into TiO2 can effectively improve the electron-hole separation of TiO2 and prolong the visible light response of TiO2. Cerium (Ce) shows variable valence states Ce3+/

Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.

If this can scale up, it's a game-changer.

A new ferroelectric polymer that efficiently converts electrical energy into mechanical strain has been developed by Penn State researchers. This material, showing potential for use in medical devices and robotics, overcomes traditional piezoelectric limitations. Researchers improved performance by

Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers -- materials composed of molecular chains and commonly used in plastics, drugs and more -- can be difficult.

Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers—materials composed of molecular chains and commonly used in plastics, drugs and more—can be difficult, according to Qiming Zhang, distinguished professor of electrical engineering.
