New light at the end of the tunnel

Who wants to decant liquids in the kitchen without spilling knows to value a funnel. Funnels are not only useful tools in the kitchen. Light can also be efficiently concentrated with funnels. In this case, the funnels have to be about 10.000-times smaller.

Battery research: Bionics reduces filling time

The latest development by engineers of KIT is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physico-chemical effect that also provides for transport in trees. The new process increases the throughput of battery production and reduces investment costs.

Bristly particles could be boon for powerplants

A well-known method of making heat sinks for electronic devices is a process called sintering, in which powdered metal is formed into a desired shape and then heated in a vacuum to bind the particles together. But in a recent experiment, some students tried sintering copper particles in air and got a big surprise.

Researchers do precise gene therapy without a needle

For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle. The technique uses electricity to "shoot" bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.

Frustration inspires new form of graphene

Researchers at Northwestern University have developed a new form of graphene that does not stack. The new material - inspired by a trash can full of crumpled-up papers - is made by crumpling the graphene sheets into balls.

A hidden order unraveled - microscopic views on quantum fluctuations

Fluctuations are fundamental to many physical phenomena in our everyday life, such as the phase transitions from a liquid into a gas or from a solid into a liquid. But even at absolute zero temperature, where all motion in the classical world is frozen out, special quantum mechanical fluctuations prevail that can drive the transition between two quantum phases. Researchers have now succeeded in directly observing such quantum fluctuations.
