Feel the beat: implanted microlasers scan heart from inside

It sounds like science fiction - but lasers beating to the rhythm of a live heart is exactly what researchers have developed to improve the understanding of heart failure and to help develop more effective treatments.

Biocompatible, piezoelectric nanofibers can help repair broken bones

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward.

Researchers find contactless way to measure thickness of carbon nanotube films

Scientists have figured out a non-invasive way to measure the thickness of single-walled carbon nanotube films, which may find applications in a wide variety of fields from solar energy to smart textiles.

Wide graphene nanoribbon promises the next generation of miniaturized electronics

A research group introduced the widest graphene nanoribbon prepared by the bottom-up approach with electrical properties surpassing those of silicon semiconductors, promising a new generation of miniaturized electronic devices.

Mary, Mary, quite contrary, how does your crystal grow?

Researchers have managed to create structures that are a complete paradox: single, continuous crystals that have multiple domains, an asymmetric shape and curved lines; they are as complex as one could expect from a 'monumental' structure.

Light from inside the tunnel

Physicists have revealed a so-far overlooked nonlinear optical mechanism that emerges from the light-induced tunneling of electrons inside dielectrics.

How to design more reliable nano- and micro-electro-mechanical systems

Scientists present insights from sophisticated small-scale mechanical experiments explaining unexpected plastic deformation of silicon on the nanoscale.

Nanocoatings could reduce complications after implant surgery

Researchers have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body.
