Germs add ripples to make 'groovy' graphene
Graphene, a two-dimensional wonder-material composed of a single layer of carbon atoms linked in a hexagonal chicken-wire pattern, has attracted intense interest for its phenomenal ability to conduct electricity. Now University of Illinois at Chicago researchers have used rod-shaped bacteria -- precisely aligned in an electric field, then vacuum-shrunk under a graphene sheet -- to introduce nanoscale ripples in the material, causing it to conduct electrons differently in perpendicular directions.

Researchers develop faster, precise silica coating process for quantum dot nanorods
Materials researchers have fine-tuned a technique that enables them to apply precisely controlled silica coatings to quantum dot nanorods in a day -- up to 21 times faster than previous methods. In addition to saving time, the advance means the quantum dots are less likely to degrade, preserving their advantageous optical properties.

Achieving a breakthrough in the formation of beam size controllable X-ray nanobeams
A research team in Japan has now succeeded in developing high precision X-ray deformable mirrors that can be configured as necessary. They are the first to have achieved the formation of three types of X-ray focused beams, which differ in focused spot size, without changing the experimental setup. These findings constitute a considerable step towards developing a multifunctional X-ray microscope, which will be able to perform a variety of microscopic analyses in one device.

Atomic bits despite zero-point energy?
Scientists at Jülich have found out that zero-point energy plays an important role in the stability of nanomagnets. These are of great technical interest for the magnetic storage of data, but so far have never been sufficiently stable. Researchers are now pointing the way to making it possible to produce nanomagnets with low zero-point energy and thus a higher degree of stability (Nanoletters).

Researchers improve performance of cathode material by controlling oxygen activity
An international team of researchers has demonstrated a new way to increase the robustness and energy storage capability of a particular class of 'lithium-rich' cathode materials -- by using a carbon dioxide-based gas mixture to create oxygen vacancies at the material's surface. Researchers said the treatment improved the energy density -- the amount of energy stored per unit mass -- of the cathode material by up to 30 to 40 percent.

Integrated trio of 2-D nanomaterials unlocks graphene electronics applications
Titled 'An integrated Tantalum Sulfide--Boron Nitride--Graphene Oscillator: A Charge-Density-Wave Device Operating at Room Temperature,' the paper describes the development of the first useful device that exploits the potential of charge-density waves to modulate an electrical current through a 2-D material. The new technology could become an ultralow power alternative to conventional silicon-based devices, which are used in thousands of applications from computers to clocks to radios.

From super to ultra-resolution microscopy
A team at Harvard's Wyss Institute for Biologically Inspired Engineering has, for the first time, been able to tell apart features distanced only 5 nanometers from each other in a densely packed, single molecular structure and to achieve the so far highest resolution in optical microscopy. Reported on July 4 in a study in Nature Nanotechnology, the technology, also called 'discrete molecular imaging', enhances the team's DNA nanotechnology-powered super-resolution microscopy platform with an integrated set of new imaging methods.

A drop of water as a model for the interplay of adhesion and stiction
Physicists at the University of Zurich have developed a system that enables them to switch back and forth the adhesion and stiction (static friction) of a water drop on a solid surface. The change in voltage is expressed macroscopically in the contact angle between the drop and the surface. This effect can be attributed to the change in the surface properties on the nanometer scale.
