Transparent artificial muscle plays Grieg to prove a point

In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music - it's the 'Morning' prelude from Peer Gynt, played on an ionic speaker. No ordinary speaker, it consists of a thin sheet of rubber sandwiched between two layers of a saltwater gel, and it's as clear as a window.

Novel topological crystalline insulator shows mass appeal

Physicists have theorized that topological crystalline insulators possess unique surface states as a result of crystalline symmetry. An international team of researchers has confirmed that experimental signature and revealed that disrupting the lattice-like structure imparts mass upon previously mass-less electrons. Furthermore, the researchers found manipulating structural symmetry offers a degree of control over the electronic phases of the solid-state material.

Self-powered nanoparticles developed to deliver healing drugs directly to bone cracks

A novel method for finding and delivering healing drugs to newly formed microcracks in bones has been invented by a team of chemists and bioengineers at Penn State University and Boston University. The method involves the targeted delivery of the drugs, directly to the cracks, on the backs of tiny self-powered nanoparticles. The energy that revs the motors of the nanoparticles and sends them rushing toward the crack comes from a surprising source - the crack itself.

Physicists create interface between atoms and superconductors

The coherence of quantum systems is the foundation upon which hardware for future information technologies is based. Quantum information is carried by units called quantum bits, or qubits. They can be used to secure electronic communications - and they enable very fast searches of databases. But qubits are also very unstable. Physicists have now developed a new electronic component which will help to deal with this problem.

Electrons jostling in a traffic jam

Quantum point contacts in electrical circuits are narrow constrictions that can impede the passage of electrons in unexpected ways. Physicists have now achieved a detailed microscopic understanding of this transport anomaly.

Carbon nanotube sensor almost as sensitive as a dog's nose

Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with Dr. Tiziana Bond has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.

Magnetic charge crystals imaged in artificial spin ice

A team of scientists has reported direct visualization of magnetic charge crystallization in an artificial spin ice material, a first in the study of a relatively new class of frustrated artificial magnetic materials-by-design known as 'Artificial Spin Ice'.

Nanofibers in dissolvable sutures could treat brain infections, reducing hospital stays

A plastic material already used in absorbable surgical sutures and other medical devices shows promise for continuous administration of antibiotics to patients with brain infections, scientists are reporting in a new study. Use of the material, placed directly on the brain's surface, could reduce the need for weeks of costly hospital stays now required for such treatment.

Molecular motors for nanotechnology: Much less power than expected?

An innovative measurement method was used at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw for estimating power generated by motors of single molecule in size, comprising a few dozens of atoms only. The findings of the study are of crucial importance for construction of future nanometer machines - and they do not instil optimism.

Quantum effects in nanowires at room temperature

Nanotechnologists at the UT research institute MESA+ have, for the first time, demonstrated quantum effects in tiny nanowires of iridium atoms. These effects, which occur at room temperature, are responsible for ensuring that the wires are almost always 4.8 nanometers - or multiples thereof - long.
