Keeping an eye on our food is the bi-national government agency Food Standards Australia and New Zealand (FSANZ), which has just released two long-awaited reports on the safety of nanoparticles in food, one on additives and one on packaging.
Researchers managed to increase light absorption in silicon by means of nanostructures etched onto photovoltaic cells. This increases the efficiency obtained in these electronic devices which are made of this element and which transform solar energy into electricity.
The Defense Advanced Research Projects Agency has awarded a $1.3 million grant to fund the development of a next-generation infrared detector that could be used in fields as varied as night vision, meteorology and space exploration.
It has been an open question whether interacting collections of quantum particles can also localize, a phenomenon known as many-body localization. Now, researchers have directly observed this localization in a system of 10 interacting ions, trapped and zapped by electric fields and lasers.
DNA is one of the most amazing molecules in nature, providing a way to carry the instructions needed to create almost any lifeform on Earth in a microscopic package. Now scientists are finding ways to push DNA even further, using it not just to store information but to create physical components in a range of biological machines.
Researchers have demonstrated an implantable triboelectric nanogenerator for in vivo biomechanical energy harvesting, which has a multilayered structure and exhibits outstanding in vivo performance and stability.
Researchers have developed a method for embedding light-emitting nanoparticles into glass without losing any of their unique properties - a major step towards 'smart glass' applications such as 3D display screens or remote radiation sensors.
