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.

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.

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.

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.

Researchers of the Opto-electronic Materials section of the TU Delft and Toyota Europe have demonstrated that several mobile electrons can be produced by the absorption of a single light particle in films of coupled quantum dots. These multiple electrons can be harvested in solar cells with increased efficiency.
