Many more bacteria have electrically conducting filaments
Microbiologists led by Derek Lovley at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or 'nanowires' in the bacterium Geobacter, announce in a new paper this month that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments.

Science Advances
Three kinds of information from a single X-ray measurement
The way in which electronic devices operate relies on the interaction between various materials. For this reason, researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists of University Jena, Germany, have now developed an innovative method that enables them to obtain several different types of information simultaneously from the interior of a nanoscale building block, and this while it is in the active state.

Revolutionizing electronics using Kirigami
A research team in the Department of Electrical and Electronic Information Engineering and the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at Toyohashi University of Technology has developed an ultrastretchable bioprobe using a 'Kirigami' designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.

Scientist's accidental exhale leads to improved DNA detector
Researchers at the Universities of Rochester and Ottawa have developed a novel nanoscale device for detecting DNA biomarkers. The device, described in Nano Letters, preconfines translocating molecules using an ultrathin nanoporous silicon nitride membrane separated from a single sensing nanopore by a nanoscale cavity. The membrane serves as a pre-filter and improves the DNA sensing capabilities of the nanopore in multiple ways. The article will be featured on the cover the February issue of the high impact journal Nano Letters.

A 100-fold leap to GigaDalton DNA nanotech
As reported in Nature, a Wyss Institute team leapfrogged their 'DNA bricks' technology by two orders of magnitude, enabling next-generation DNA bricks to self-assemble into three-dimensional nanostructures that are 100 times more complex than those created with existing methods. The study provides user-friendly computational tools to design DNA nanostructures with complex cavities (and possibly surfaces) that have the potential to serve as building components in numerous nanotechnological applications in medicine and engineering.

DNA-origami surpasses important thresholds
It is the double strands of our genes that make them so strong. Using a technique known as DNA origami, biophysicist Hendrik Dietz has been building nanometer-scale objects for several years at the Technical University of Munich (TUM). Now Dietz and his team have not only broken out of the nanometer realm to build larger objects, but have also cut the production costs a thousand-fold. These innovations open a whole new frontier for the technology.

Towards data storage at the single molecule level
Similar to normal hard drives, so-called spin-crossover molecules can save information via their magnetic state. A research team from Kiel University has now managed to place a new class of spin-crossover molecules onto a surface and to improve its storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in journal Nano Letters.

Bioelectronic 'nose' can detect food spoilage by sensing the smell of death
Strong odors are an indicator that food has gone bad, but there could soon be a new way to sniff foul smells earlier on. As reported in ACS Nano, researchers have developed a bioelectronic "nose" that can specifically detect a key decay compound at low levels, enabling people to potentially take action before the stink spreads. It can detect rotting food, as well as be used to help find victims of natural disasters or crimes.

Flipping the electron spin
When lithium-ion batteries are charged too quickly, metallic lithium gets deposited on the anodes. This reduces battery capacity and lifespan and can even destroy the batteries. Scientists at the Technical University of Munich (TUM) and the Forschungszentrum Jülich have now presented a process that, for the first time ever, allows this so-called lithium plating process to be investigated directly. This puts new strategies for quick-charging strategies close at hand.

Nanomaterials: How to separate linear and ring-shaped molecules
What is the difference between linear chains and rings composed of the same material? The molecular building blocks are identical, but from a mathematical point of view the structures have distinct topologies, ring and linear chain. This difference is readily recognizable on a macroscopic scale, but represents a tricky task on the microscopic scale. Physicists around Lisa Weiss and Christos Likos of the University of investigated strategies to separate nano- and microparticles of distinct topology.

Hybrid electrolyte enhances supercapacitance in vertical graphene nanosheets
Supercapacitors can store more energy than and are preferable to batteries because they are able to charge faster, mainly due to the vertical graphene nanosheets that are larger and positioned closer together. Using VGNs as the material for supercapacitor electrodes offers advantages that can be enhanced depending on how the material is grown, treated and prepared to work with electrolytes. In this week's Journal of Applied Physics, researchers discuss ways to improve the material's properties.

Copper will replace toxic palladium and expensive platinum in the synthesis of medications
Chemists of Ural Federal University with colleagues from India proved the effectiveness of copper nanoparticles as a catalyst on the example of analysis of 48 organic synthesis reactions. One of the advantages of the catalyst is its insolubility in traditional organic solvents. This makes copper nanoparticles a valuable alternative to heavy metal catalysts, for example palladium, which is currently used for the synthesis of many pharmaceuticals and is toxic for cells.
