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 ...

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 ...

Cutting light with a comb

(Phys.org)—Quantum physicists from ETH Zurich have discovered special properties in a laser, thanks to which portable devices can be built to analyse gases and liquids accurately and reliably in the future.

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 ...

Vibrating 2-D materials

Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure ...

Researchers find new shape for hydrophobic molecules in water

The embedding of hydrophobic molecules in water looks quite different than previously assumed. In water, hydrophobic molecules are surrounded by a two different water populations: the inner shell forms a two-dimensional network ...
