Physical Review X
Steering chemical reactions with laser pulses
Ultra short laserpulses in the femtosecond-range give scientists a powerful new method of controlling chemical reactions. A team of researchers could now show that the fragmentation of carbohydrates can be controlled by these pulses.

7th International Nanotoxicology Congress
PETA science consortium to present hazard testing strategy at nanotoxicology meeting
PETA International Science Consortium will present a non-animal tiered-testing strategy for nanomaterial hazard assessment at the 7th International Nanotoxicology Congress being held in Antalya, Turkey on April 23-26, 2014. The proposed strategy will generate meaningful information on nanomaterial properties and their interaction with biological systems. It's cost-effective, reduces animal use, and can be applied for assessing risk and making intelligent regulatory decisions regarding the use and disposal of nanomaterials.

First size-based chromatography technique for the study of living cells
Using nanodot technology, Berkeley Lab researchers demonstrated the first size-based form of chromatography for studying the membranes of living cells. This unique physical approach to probing cellular membrane structures reveals critical information that can't be obtained through conventional microscopy.

Vacuum ultraviolet lamp of the future created in Japan
A team of researchers in Japan has developed a solid-state lamp that emits high-energy ultraviolet (UV) light at the shortest wavelengths ever recorded for such a device, from 140 to 220 nanometers. This is within the range of vacuum-UV light -- so named because while light of that energy can propagate in a vacuum, it is quickly absorbed by oxygen in the air.

Cloaked DNA nanodevices survive pilot mission
By mimicking a viral strategy, scientists at Harvard's Wyss Institute for Biologically Inspired Engineering have created the first cloaked DNA nanodevice that survives the body's immune defenses. Their success opens the door to smart DNA nanorobots that use logic to spot cancerous tissue and manufacture drugs on the spot to cripple it, as well as artificial microscopic containers called protocells that detect pathogens in food or toxic chemicals in drinking water.

Nanomaterial outsmarts ions
Ions are an essential tool in chip manufacturing, but they can also be used to produce nano-sieves. A large number of electrons must be removed from the atoms for this purpose. Such ions either lose a large amount of energy or almost no energy at all as they pass through a membrane that measures one nanometer in thickness. Researchers report in the journal Physical Review Letters that this discovery is an important step towards developing novel types of electronic components made of graphene.

Like a hall of mirrors, nanostructures trap photons inside ultrathin solar cells
'We want to make sure light spends more quality time inside a solar cell,' said Mark Brongersma, a professor of materials science and engineering at Stanford. He and two co-authors surveyed 109 scientific papers involving ways to maximize the collisions between photons and electrons in the thinnest possible layer of photovoltaic material. The goal is to reveal trends and best practices that will help lower solar energy costs.

RNA shows potential as boiling-resistant anionic polymer material for nanoarchitectures
Nanotechnology researchers at the University of Kentucky have discovered new methods to build boiling-resistant nanostructures and arrays using a new RNA triangle scaffold. These new RNA nanoarchitechtures can be used to form arrays with a controllable repeat number of the scaffold, resembling monomer units in a polymerization reaction. Their enhanced structural stability and controllability at the nano scale offer key advantages over traditional chemical polymers.

High-performance, low-cost ultracapacitors built with graphene and carbon nanotubes
By combining the powers of two single-atom-thick carbon structures, researchers at the George Washington University's Micro-propulsion and Nanotechnology Laboratory have created a new ultracapacitor that is both high performance and low cost. The device, described in the Journal of Applied Physics, capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties.

Innovative strategy to facilitate organ repair
A significant breakthrough could revolutionize surgical practice and regenerative medicine. A team led by Ludwik Leibler from the Laboratoire Matiere Molle et Chimie (CNRS/ESPCI Paris Tech) and Didier Letourneur from the Laboratoire Recherche Vasculaire Translationnelle (INSERM/Universites Paris Diderot and Paris 13), has just demonstrated that the principle of adhesion by aqueous solutions of nanoparticles can be used in vivo to repair soft-tissue organs and tissues.

Global scientific team 'visualizes' a new crystallization process
By combining a synchrotron's bright X-ray beam with high speed X-ray cameras, scientists from Stanford University in California and KAUST in Saudi Arabia shot a 'movie' showing how organic molecules form into crystals. This is a first. Their new techniques will improve our understanding of crystal packing and should help lead to better electronic devices as well as pharmaceuticals -- indeed any product whose properties depend on precisely controlling crystallization, as this paper describes.
