University research team's new approach enhances quantum-based secure communication
University of Calgary scientists have overcome an "Achilles' heel" of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets. The team's research -- published in the journal Physical Review Letters back-to-back with similar work by a group from Hefei, China -- also removes a big obstacle to realizing future applications of quantum communication, including a fully functional quantum network.

Researchers discover breakthrough technique that could make electronics smaller and better
An international group of researchers from the University of Minnesota, Argonne National Laboratory and Seoul National University have discovered a groundbreaking technique in manufacturing nanostructures that has the potential to make electrical and optical devices smaller and better than ever before. A surprising low-tech tool of Scotch Magic tape ended up being one of the keys to the discovery.

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.

Almost as sensitive as a dog's nose
Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with US researcher 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.

Molecular motors: Power much less 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 instill optimism.

Process devised for ultrathin carbon membranes
A research team working with Professor Dr. Armin Gölzhäuser of Bielefeld University has succeeded in developing a new path to produce carbon nanomembranes. In the future, such nanomembranes are expected to be able to filter out very fine materials.The advantage of the new method of fabrication is that it allows a variety of different carbon nanomembranes to be generated which are much thinner than conventional membranes.
