High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time. Now, researchers has found a way of greatly reducing the damaging effects these metals suffer from exposure to hydrogen.
The worries that even nanotechnology proponents had in the early 2000s about possible health and environmental risks - and their impact on investor and consumer confidence - seem to have evaporated. So what's changed?
Researchers have found that quantum effects are the reason that hydrogen sulphide - which has the distinct smell of rotten eggs- behaves as a superconductor at record-breaking temperatures, which may aid in the search for room temperature superconductors.
Researchers have developed a piezo-optomechanical circuit that converts signals among optical, acoustic and radio waves. A system based on this design could move and store information in next-generation computers.
Researchers have shown that a law of physics having to do with electron transport at nanoscale can also be analogously applied to the ion transport. This discovery provides insight into a key aspect of how ion channels function within our living cells.
Scientists have developed a new method that relies on fluid flow to manipulate and assemble multiple particles. This new technique can trap a range of submicron- to micron-sized particles, including single DNA molecules, vesicles, drops or cells.
Researchers have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available - one capable of identifying a single lightweight molecule in a highly dilute solution.
