Researchers have developed a new system that can produce stable, amorphous nanoparticles in large quantities that dissolve quickly. But that's not all. The system is so effective that it can produce amorphous nanoparticles from a wide range of materials, including for the first time, inorganic materials with a high propensity towards crystallization, such as table salt.
Discovery of a compound that undergoes a colorimetric response to a whole host of different ions. However, the most remarkable facet of the chemistry is that the detecting species is not made directly by the scientist, but because the response spontaneously self-assembles to give a sensor for each specific anion.
Physicists succeeded in synthesizing boron-doped graphene nanoribbons and characterizing their structural, electronic and chemical properties. The modified material could potentially be used as a sensor for the ecologically damaging nitrogen oxides.
Silicon electronics faces a challenge: the latest circuits measure just 7nm wide - between a red blood cell (7,500nm) and a single strand of DNA (2.5nm). The size of individual silicon atoms (around 0.2nm) would be a hard physical limit (with circuits one atom wide), but its behaviour becomes unstable and difficult to control before then.
Miniscule artificial scaffolding units made from nano-fibre polymers and built to house plant cells have enabled scientists to see for the first time how individual plant cells behave and interact with each other in a three-dimensional environment.
The University of Nottingham is to lead a GBP6.5m research project which aims to make the leap from 2D to 3D in the development of advanced materials and realise the true potential of regenerative medicine and medical devices for the future.
