Nanocomposite material provides photonic switching

(PhysOrg.com) -- Integrated photonic devices represent the wave of future technology. These devices will be extremely small, making use of photons on the nanoscale, and (hopefully) be very efficient in terms of power use. ...

'Molecular levers' may make materials better

(Phys.org)—In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could use these molecular ...

Nanovaccine boosts immunity in sufferers of metabolic syndrome

A new class of biomaterial developed by Cornell researchers for an infectious disease nanovaccine effectively boosted immunity in mice with metabolic disorders linked to gut bacteria – a population that shows resistance ...

The origin of ultrahigh piezoelectric response

All ferroelectric materials possess a property known as piezoelectricity in which an applied mechanical force can generate an electrical current and an applied electrical field can elicit a mechanical response. Ferroelectric ...

Chemists characterize 3-D macroporous hydrogels

Carnegie Mellon University chemists have developed two novel methods to characterize 3-dimensional macroporous hydrogels—materials that hold great promise for developing "smart" responsive materials that can be used for ...
