Successful companies founded by physicists often break the Silicon Valley model

A new AIP report, titled Physics Entrepreneurship and Innovation, is based on extensive interviews with 140 PhD physicists and other professionals who co-founded and work at some 91 startup companies in 14 states that were established in the last few decades. These companies are engaged in making medical devices, manufacturing tools, nanotechnology, lasers and optical devices, renewable energy technologies and other products.

Atomic switcheroo explains origins of thin-film solar cell mystery

Treating cadmium-telluride solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why. Now, an atomic-scale examination of the thin-film solar cells has answered this decades-long debate about the materials' photovoltaic efficiency increase after treatment.

Filters made of graphene - the thinnest feasible membrane

A new nanomembrane made out of graphene is extremely light and breathable. Not only can this open the door to a new generation of functional waterproof clothing, but also to ultra-rapid filtration. The membrane is as thin as is technologically feasible.

Steering chemical reactions with laser pulses

With ultra-short laser pulses, chemical reactions can be controlled; electrons have little mass and are therefore influenced by the laser, whereas the atomic nuclei are much heavier and are hardly affected.

Disorder on the nanoscale may be responsible for solar-cell efficiency

In the past few years, perovskite solar cells have made large leaps forward in efficiency, recently achieving energy conversion with up to 16 percent efficiency. These simple and promising devices are easy enough to make and are made up of earth abundant materials, but little work has been done to explore their atomic makeup.

PETA science consortium to present hazard testing strategy at nanotoxicology meeting

PETA International Science Consortium will present a non-animal tiered-testing strategy for nanomaterial hazard assessment at the 7th International Nanotoxicology Congress being held in Antalya, Turkey on Apr. 23-26, 2014. The proposed strategy will generate meaningful information on nanomaterial properties and their interaction with biological systems.

Quantum simulators developed to study inaccessible physical systems

Quantum simulators recreate the behaviour on a microscopic scale of biological and quantum systems and even of particles moving at the speed of light. The exact knowledge of these systems will lead to applications ranging from more efficient photovoltaic cells to more specific drugs. Researchers are working on the design of several of these quantum simulators so they can study the dynamics of complex physical systems.
