Researchers have introduced a new method of detection that allows the entire class of methamphetamine drugs to be detected in water. A probe equipped with synthetic receptor molecules responds to a grouping of atoms that is present in all methamphetamines.
Sandia National Laboratories has come up with an inexpensive way to synthesize titanium-dioxide nanoparticles and is seeking partners who can demonstrate the process at industrial scale for everything from solar cells to light-emitting diodes (LEDs).
Scientists are using a pioneering method of 'caging' and cooling water molecules to study the change in orientation of the magnetic nuclei at the centre of each hydrogen atom - a process which transforms the molecule from one form of water to another.
The European Commission and its non-food Scientific Committee on Emerging and Newly Identified Health Risks, SCENIHR, published the final opinion on 'Nanosilver: safety, health and environmental effects and role in antimicrobial resistance'.
Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, and electric vehicles. If successful, the batteries will last longer and perform better, leading to a cost advantage for electric vehicles.
Nanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.
Physicists have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nanocavities.
Processes on the atomic scale can only be described accurately by using the laws of quantum mechanics. Physicists have now succeeded for the first time to completely determine the state of such a quantum mechanical system in experiments.
What links legendarily sharp Damascene swords of the past with flexible electronics and high-performance electrical wiring of the future? They all owe their remarkable properties to different structural forms of carbon.
