Novel approach towards nanomaterials developed
During this process, the team discovered an intriguing phenomenon
26-Sep-2023 - Scientists from the Friedrich Schiller University Jena and the Friedrich Alexander University Erlangen-Nuremberg, both Germany, have successfully developed nanomaterials using a so-called bottom-up approach. As reported in the scientific journal ACS Nano, they exploit the fact that crystals often ...
Precisely arranging nanoparticles
Research team develops plasmonic molecules from nanoparticles
19-Sep-2023 - In the incredibly small world of molecules, the elementary building blocks – the atoms – join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect. A research team at the University of Göttingen ...
Observing nanoparticles with unprecedented precision
Illuminated: Researchers investigate new physical phenomena on the nanoscale with microstructured fibers
15-Sep-2023 - Researchers at Leibniz IPHT have succeeded in contributing to significant advances in deciphering tiny nanoobjects: Using special optical fibers, they identified a new optical mode that enables uniform illumination along the entire length of the fiber, and determined the resolution limit of ...
Cleaning water with ‘smart rust’ and magnets
New method for pollutants such as crude oil, glyphosate, microplastics and hormones
22-Aug-2023 - Pouring flecks of rust into water usually makes it dirtier. But researchers of FAU have developed special iron oxide nanoparticles they call “smart rust” that actually makes it cleaner. Smart rust can attract many substances, including oil, nano- and microplastics, as well as the herbicide ...
Gold buckyballs, oft-used nanoparticle ‘seeds’ are one and the same
Rice lab discovers commonly used nanoparticles are cousins of original buckyballs
21-Aug-2023 - Rice University chemists have discovered that tiny gold “seed” particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spherical molecules that are cousins of the carbon buckyballs discovered at Rice in 1985. Carbon buckyballs ...
Molecular movie shows displaced electrons drive gold nanoparticle oscillations
Result defies established models of nanoparticle behaviour
03-Aug-2023 - Photocatalysis, sensors, solar cells: nanoparticles that are excited by light promise a variety of applications, if the processes behind their behaviour can be controlled. One such process is a type of collective electron motions. These movements lead to energy exchange in the nanoparticle that ...
Surface analysis of catalyst particles in aqueous solutions
The results are relevant for the development of efficient photoelectrodes for the production of green hydrogen
25-Jul-2023 - Green hydrogen can be produced directly in a photoelectrochemical cell, splitting water with solar energy. However, this requires the development of super-efficient photoelectrodes that need to combine many talents at the same time: They must be excellent at converting sunlight into electricity, ...
New material transforms light, creating new possibilities for sensors
“This process gives us a whole new way of designing materials”
22-Jun-2023 - A group of scientists and engineers that includes researchers from The University of Texas at Austin have created a new class of materials that can absorb low energy light and transform it into higher energy light. The new material is composed of ultra-small silicon nanoparticles and organic ...
New recipes for better solar fuel production
Researchers optimize production of solar fuels by using novel combinations of methods and materials to create new types of photocatalysts
20-Jun-2023 - Just as a superb meal requires the right ingredients prepared expertly, the production of better green fuel alternatives requires combining the right materials and methods. Recently, a team of researchers from China and the UK have found new ways to optimise the recipe for the production of solar ...
Shrimp from Finding Nemo could help keep your white bread white
Ben-Gurion University researchers discover new principle in optics
01-Jun-2023 - The Pacific Cleaner Shrimp may hold the secret to keeping white bread white. Inorganic nanoparticles such as titanium dioxide and zinc oxide are widely used as whitening agents in foods, cosmetics, and paints. However, due to health concerns, there is currently an intensive search to find ...
