Nanoengineers have developed a mouth guard that can monitor health markers, such as lactate, cortisol and uric acid, in saliva and transmit the information wirelessly to a smart phone, laptop or tablet.
Researchers have developed the first nano/micro-textured highly slippery surfaces able to outperform lotus leaf-inspired liquid repellent coatings, particularly in situations where the water is in the form of vapor or tiny droplets.
A new paper demonstrates the rapid and scalable production of Zinc Oxide nanomaterials using a technique called electrochemical anodization. The technique can be controlled to give rise to a wide range of interesting structures, with different sizes and shapes, which can be tailored towards specific applications.
Liquid Bi shows a peculiar dispersion of the acoustic mode, which is related to the Peierls distortion in the crystalline state. These results will provide valuable inspiration to researchers developing new materials in the nanotechnology field.
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.
