How molecules interact with a laser field

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin ...

Carrying and releasing nanoscale cargo with "nanowrappers"

This holiday season, scientists at the Center for Functional Nanomaterials (CFN)—a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory—have wrapped a box of a different kind. Using ...

The Cygnus Loop

The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the detritus of the explosive death of a massive star about ten to twenty thousand years ago. Detailed modeling of its spectacular filamentary shape ...

Nanodiamonds as photocatalysts

Climate change is in full swing and will continue unabated as long as CO2 emissions continue. One possible solution is to return CO2 to the energy cycle: CO2 could be processed with water into methanol, a fuel that can be ...

Caribbean to test greenhouse-gas linked ocean acidity

Tourism and fishery-dependent Caribbean nations plan to test the acidity of the Caribbean Sea as a result of increased absorption of greenhouse gases, a senior regional official said Friday.

Composite significantly reduces electromagnetic pollution

In a paper published in Nano, a group of researchers from Anhui University of Science and Technology have synthesized PANI/Zn ferrite composites which have shown excellent microwave absorption performance. They could be used ...

Urea-absorbing ability of giant clams

NUS biologists have discovered that the fluted giant clam absorbs urea from its surroundings and the absorption rate is enhanced by exposure to light.
