Tiny generators turn waste heat into power

The second law of thermodynamics is a big hit with the beret-wearing college crowd because of its implicit existential crunch. The tendency of a closed systems to become increasingly disordered if no energy is added or removed ...

'Plasmonic nanoantennas' show promise in optical innovations

(PhysOrg.com) -- Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, ...

Wizard at circuits, physics

Sensitive nano oscillator can detect pathogens

(PhysOrg.com) -- By watching how energy moves across a tiny device akin to a springing diving board, Cornell researchers are a step closer to creating extraordinarily tiny sensors that can instantly recognize harmful substances ...

Researchers explain magnetic field misbehavior in solar flares

When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away ...
