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 ...
Low-cost molybdenum complex paves the way for sustainable photochemistry
Scientists use molybdenum for photocatalysis and photon upconversion
06-Sep-2023 - Given the urgent need for transforming how we use and produce energy, researchers are working hard to find sustainable and cost-effective materials for light-driven chemical applications. To date, this research field heavily relies on expensive precious metal or rare-earth metal complexes with ...
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 ...
Tracing invisible particles
Automated analysis of microplastics
28-Jul-2023 - How high are concentrations of microplastics in the environment, in our drinking water or in foods? Researchers at the Technical University of Munich (TUM) have developed an automated analysis method for the identification and quantification of particles. Microplastics are everywhere in the ...
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, ...
Detecting nanoplastics – in fractions of a second
Basis for new measurement devices
19-Jul-2023 - Tiny plastic particles are an environmental problem. They can even penetrate living cells. A method has now been developed at TU Wien to detect such particles quickly and with high sensitivity. It is well known that microplastics are a problem: They are tiny, barely visible plastic particles that ...
Using particle showers to scan the interior of structures
HZDR researchers seek to harness muon imaging for bridges, chemical parks, and Castor containers
30-Jun-2023 - Earth is constantly being struck by cosmic particles. High-energy muons can easily penetrate several meters of steel or concrete. A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) seeks to harness the potential of this unavoidable background radiation to view the interior of industrial ...
