 Nature Communications'Next-generation' optical tweezers trap tightly without overheating Engineers at Harvard have created a device that may make it easier to isolate and study tiny particles such as viruses. Their plasmonic nanotweezers, revealed this month in Nature Communications, use light from a laser to trap nanoscale particles. The new device creates strong forces more efficiently than traditional optical tweezers and eliminates a problem that caused earlier setups to overheat.

Journal of the American Chemical SocietyEdible carbon dioxide sponge A year ago Northwestern University chemists published their recipe for a new class of nanostructures made of sugar, salt and alcohol. Now, the same team has discovered the edible compounds can efficiently detect, capture and store carbon dioxide. The porous crystals -- known as metal-organic frameworks -- are made from all-natural ingredients and simple to prepare, giving them a huge advantage over other MOFs, which are usually prepared from materials derived from crude oil.

Nanoplasmonic Sensors and Spectroscopy Meeting Nature CommunicationsBimetallic nanoantenna separates colors of light Researchers at Chalmers University of Technology have built a very simple nanoantenna that directs red and blue colors in opposite directions, even though the antenna is smaller than the wavelength of light. The findings -- published in the online journal Nature Communications this week -- can lead to optical nanosensors being able to detect very low concentrations of gases or biomolecules.

Nature ChemistryScientists lay out plans for efficient harvesting of solar energy Solar power could be harvested more efficiently and transported over long distances using tiny molecular circuits, according to research inspired by new insights into natural photosynthesis. Contact: Clare Ryan
Public Release: 23-Sep-2011
Nature ChemistryNature offers key lessons on harvesting solar power, says U of T chemistry professor Clean solutions to human energy demands are essential to our future. While sunlight is the most abundant source of energy at our disposal, we have yet to learn how to capture, transfer and store solar energy efficiently. According to University of Toronto chemistry professor Greg Scholes, the answers can be found in the complex systems at work in nature. Contact: Kim Luke

Physical Review LettersScientists observe how superconducting nanowires lose resistance-free state Physicists have measured the temperatures at which collections of electrons build up enough heat to force regions along superconducting aluminum nanowires to switch to a non-superconducting state. The information could help engineers build more reliable nanowires and more efficient nano-electronics. Contact: Ashley Yeager

NatureLike fish on waves: electrons go surfing Physicists at the RUB, working in collaboration with researchers from Grenoble and Tokyo, have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighbouring QD. The researchers report in Nature. Contact: Prof. Dr. Andreas Wieck

Nature MaterialsHow to produce flexible CIGS solar cells with record efficiency The technology yielding flexible solar cells with an 18.7 percent world record efficiency developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, has now been published in Nature Materials. Key to the breakthrough is the control of the energy band gap grading in the copper indium gallium (di)selenide semiconductor, also known as CIGS, the layer that absorbs light and converts it into electricity.

NatureSlippery slope:Researchers take advice from a carnivorous plant Adopting the pitcher plant's slick prey-catching strategy, a group of applied scientists at Harvard have created a material that repels just about any type of liquid, including blood and oil, and does so even under harsh conditions like high pressure and freezing temperatures. The bio-inspired liquid repellence technology should find applications in biomedical fluid handling, fuel transport, and anti-fouling and anti-icing technologies. It could even lead to self-cleaning windows and improved optical devices.

Nature NanotechnologyWhy carbon nanotubes spell trouble for cells Carbon nanotubes and other long nanomaterials can spell trouble for cells. The reason: Cells mistake them for spheres and try to engulf them. Once they start, cells cannot reverse course, and complete ingestion never occurs. Researchers at Brown University detail for the first time how cells interact with carbon nanotubes, gold nanowires and asbestos fibers. Results are published in Nature Nanotechnology.
