Ice-like phonons in liquid water discovered

For more than 100 years, scientists have debated what the underlying molecular structure of water is, and the common view has been that H2O molecules are either "water-like" or "ice-like." Now through computer simulation ...

How to make a "perfect" solar absorber

The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that reach Earth's surface ...

The water dance

Water (H2O) is a unique molecule that holds amazing properties. Scientists have a good grasp of the structure and chemistry of individual molecules of water. But understanding how large numbers of these molecules move and ...

Manipulating Lorentz and Fano spectral line shapes

(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the ...

Hydrogen-making algae's 'Achilles' heel' discovered

(PhysOrg.com) -- Scientists have discovered how oxygen stops green algae from producing hydrogen. The findings could help those working towards 'solar H2-farms' in which microorganisms produce hydrogen fuel from sunlight ...

Ubiquitous Energy sets focus on solar cell technology

(Phys.org)—Can windows, tablets and e readers turn light into power? Can a surface coated with solar cells take sunlight and the glow of bulbs and change them into energy? As reported in Technology Review, expert scientists ...
