Researchers show that they can turn this pollutant into something useful - a material in high demand for high- tech batteries that are needed to store 'green' energy such as solar power, while limiting the environmental impact of current power plants.
Stacking layers of nanometer-thin semiconducting materials at different angles is a new approach to designing the next generation of energy-efficient transistors and solar cells. Researchers used the vibrations between two layers to decipher their stacking patterns. Their study provides a platform for engineering two-dimensional materials with optical and electronic properties that strongly depend on stacking configurations.
Future radar imaging systems and 5G communication systems will generate improved resolution and provide higher data-transmission rates when operated at higher frequencies, but at the cost of increased power consumption. To reduce power consumption, increase performance, and lower costs, the European project INSIGHT is aiming at developing III-V CMOS technology.
Scientists have developed structures on a nanometric scale that can be used as biosensors for medical, food or environmental sectors to detect diseases, allergens or contaminants; or can be used to reduce the reflection of solar cells in order to increase their efficiency.
Researchers have made the first direct measurement that characterizes the exotic physics in a photonic platform. These techniques may be extended to more complex systems, such as one in which strong interactions and long-range quantum correlations play a role.
Utilizing self-assembly on atomically flat, transparent substrates, a team of scientists has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabrication of optoelectronic devices with molecular precision.
A technique called acoustic force spectroscopy uses standing sound waves in a fluid channel to tug on DNA and other biomolecules in a precise and easily controllable way, revealing information about the molecules' structure and mechanical properties.
Researchers involved in a national effort to develop cancer treatments that harness nanotechnology are recommending pivotal changes in the field because experiments with laboratory animals and efforts based on current assumptions about drug delivery have largely failed to translate into successful clinical results.
