Physicists create world's smallest semiconductor laser

Physicists at The University of Texas at Austin, in collaboration with colleagues in Taiwan and China, have developed the world's smallest semiconductor laser, a breakthrough for emerging photonic technology with applications ...

Rewriting quantum chips with new laser technique

(Phys.org) -- The promise of ultrafast quantum computing has moved a step closer to reality with a technique to create rewritable computer chips using a beam of light. Researchers from The City College of New York (CCNY) ...

New energy source for future medical implants: sugar

MIT engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed ...

Synthetic cells used to bioengineer new forms of silica

(Phys.org) -- Scientists do not fully understand how nature uses proteins to develop new materials and minerals, but learning more about the natural processes could lead to bioengineering methods such as the biological synthesis ...

An unlikely route to ferroelectricity

(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain materials. This ...

3-D, after-the-fact focus image sensors invented

(PhysOrg.com) -- At the heart of digital photography is a chip called an image sensor that captures a map of the intensity of the light as it comes through the lens and converts it to an electronic signal.

New device could bring optical information processing

(PhysOrg.com) -- Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.

Nano bundles pack a powerful punch

Rice University researchers have created a solid-state, nanotube-based supercapacitor that promises to combine the best qualities of high-energy batteries and fast-charging capacitors in a device suitable for extreme environments.
