New research demonstrates that liquids can be investigated by X-ray emission spectroscopy without using membranes after all. At the synchrotron source BESSY II, a group of scientists has built a special setup -- the LiXEdrom. It is unique in that the liquid is shot as a jet through the X-ray beam.
The precious commodity of water

Water is a valuable resource, which is why researchers are demonstrating how we can extract precious drinking water from air, discover a leak in pipeline systems and even effectively clean sewage water.
Playing snooker with atoms

Scientists speak of sputtering when energy-rich ions hit a solid object and cause atoms to be released from its surface. The phenomenon can be exploited to apply microscopically thin coatings to glass surfaces. A research team has developed a special sputtering technique that greatly increases the efficiency of the coating process.
Graphene may hold key to speeding up DNA sequencing

Researchers have demonstrated that graphene can act as an artificial membrane separating two liquid reservoirs. By drilling a tiny pore just a few-nanometers in diameter, called a nanopore, in the graphene membrane, they were able to measure exchange of ions through the pore and demonstrated that a long DNA molecule can be pulled through the graphene nanopore just as a thread is pulled through the eye of a needle.
Many roads lead to superconductivity

Researchers have discovered a magnetic signature that occurs universally among all iron-based superconductors, even if the parent compounds from which the superconductors are made possess different chemical properties.
CRISPR critters: Scientists identify key enzyme in microbial immune system

Using protein crystallography beamlines at Berkeley Lab's Advanced Light Source, a team of researchers has resolved the atomic-scale crystal structure of an enzyme called "Csy4" that plays a key role in a microbial immune system. The research provides important new clues to the fundamental role of RNA in the evolution of life.
