Magnetite nanowires with sharp insulating transition

Magnetite (Fe3O4) is best known as a magnetic iron ore, and is the source of lodestone. It also has potential as a high-temperature resistor in electronics. In new research led by Osaka University, published in Nano Letters, ...

Caught in the act: Images capture molecular motions in real time

Researchers have used ultra-high-speed X-ray pulses to make a high-resolution "movie" of a molecule undergoing structural motions. The research, published in Nature Chemistry, reveals the dynamics of the processes in unprecedented ...

Charge transfer within transition-metal dyes analysed

Transition-metal complexes in dye-based solar cells are responsible for converting light into electrical energy. A model of spatial charge separation within the molecule has been used to describe this conversion. However, ...

Could vacuum physics be revealed by laser-driven microbubbles?

A vacuum is generally thought to be nothing but empty space. But in fact, a vacuum is filled with virtual particle-antiparticle pairs of electrons and positrons that are continuously created and annihilated in unimaginably ...

Chemists give chance a helping hand

Whether they are synthetic materials such as PET and Teflon, medicines or flavourings, life without synthetically produced compounds is barely conceivable. The chemical industry depends on efficient, long-term methods of ...

Laser trick produces high-energy terahertz pulses

A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were able to produce ...
