2 become 1 with the 3-D NanoChemiscope
The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "seeing."

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.

New tests for determining health and environmental effects of nanomaterials
A group of international experts from government, industry and academia have concluded that alternative testing strategies that don't rely on animals will be needed to cope with the wave of new nanomaterials emerging from the boom in nanoscience and nanotechnology. Their consensus statement from a workshop on the topic appears in the journal ACS Nano.

3D graphene: Solar cells' new platinum?
Platinum is a key material in dye-sensitized solar cells, where it is used to make counter electrodes. A new, 3D form of graphene made from carbon monoxide and lithium oxide was used to replace the platinum with virtually no loss in electrical generating capacity.

'Groovy' hologram creates strange state of light
A new three-in-one optical element can control light's amplitude, phase, and polarization through a wedding of old-fashioned holograms and state-of-the-art nanoscale features. An unusual state of light, a radially polarized beam, which is important for microscopy and particle manipulation, has been created by sending conventional laser light through this holographic plate.

First time: NJIT researchers examine dynamics of liquid metal particles at nanoscale
Two NJIT researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale. "Numerical simulation of ejected molten metal nanoparticles liquified by laser irradiation: Interplay of geometry and dewetting," appeared in Physical Review Letters (July 16, 2013).

Graphene nanoscrolls are formed by decoration of magnetic nanoparticles
Researchers at Umeå University in Sweden, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets. The new material may have very good properties for application as electrodes in for example Li-ion batteries.

Scientists find asymmetry in topological insulators
New research shows that a class of materials being eyed for the next generation of computers behaves asymmetrically at the sub-atomic level. This research is a key step toward understanding the topological insulators that may have the potential to be the building blocks of a super-fast quantum computer that could run on almost no electricity.

High-angle helix helps bacteria swim
It's counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers at Brown University have figured out why. It's the angle of the coil that matters. Findings are reported in Physical Review Letters.
