Despite the many advances in portable electronic devices, one thing remains constant: the need to plug them into a wall socket to recharge. Now researchers, reporting in the journal ACS Nano, have developed a light-weight, paper-based device inspired by the Chinese and Japanese arts of paper-cutting that can harvest and store energy from body movements.

Portable electronic devices, such as watches, hearing aids and heart monitors, often require only a little energy. They usually get that power from conventional rechargeable batteries...

The experimental realization of ultrathin graphene – which earned two scientists from Cambridge the Nobel Prize in physics in 2010 – has ushered in a new age in materials research. What started with graphene has evolved to include numerous related single-atom-thick materials, which have unusual properties due to their ultra-thinness...

Physicists probe exotic state of nuclear matter at Europe’s LHC. Findings from Rice University physicists working at Europe’s Large Hadron Collider (LHC) are providing new insight about an exotic state of matter, “quark-gluon plasma” that occurs when protons and neutrons melt. LHC is able to smash together the nuclei of atoms at nearly the speed of the light. The energy released in these collisions is vast and allows physicists to recreate the hot, dense conditions that existed in the early universe...

Two black diamonds on a superconducting chip (12x4mm). The wiggly line is a resonator, coupling the two diamonds.

Atomic defects in diamonds can be used as quantum memories. Researchers at TU Wien have been studying the quantum properties of such diamonds, but only now have they succeeded in coupling the specific defects in two such diamonds with one another. This is an important prerequisite for the development of new applications, such as highly sensitive sensors and switches for quantum computers.

“Unfortunately, quantum states are very fragile and decay very quickly,” explains Johannes Majer, head of the hybrid quantum research group, Institute of Atomic and Subatomic Physics at TU Wien...
