That isn’t tea, but the paradox still applies: Dispersing gold nanoparticles in an aqueous chlorine solution. (Courtesy: Ai Du) Topics: Aerogels, Einstein, Materials Science, Nanomaterials, Soft Materials If you stir a colloidal solution containing nanoparticles, you might expect the particles to disperse evenly through the liquid. But that’s not what happens. Instead, the particles endContinue reading “Liquid Squeezing…”

Stronger Than Steel…
Researchers from the University of Connecticut and colleagues have created a highly durable, lightweight material by structuring DNA and then coating it in glass. The resulting product, characterized by its nanolattice structure, exhibits a unique combination of strength and low density, making it potentially useful in applications like vehicle manufacturing and body armor. (Artist’s concept.)Continue reading “Stronger Than Steel…”

Beyond Attogram Imaging…
When X-rays (blue color) illuminate an iron atom (red ball at the center of the molecule), core-level electrons are excited. X-ray excited electrons are then tunneled to the detector tip (gray) via overlapping atomic/molecular orbitals, which provide elemental and chemical information about the iron atom.

Graphical abstract. Credit: Nanomaterials (2023). DOI: 10.3390/nano13081404 Topics: Biology, Environment, Nanomaterials, Nanotechnology Among the biggest environmental problems of our time, micro- and nanoplastic particles (MNPs) can enter the body in various ways, including through food. And now, for the first time, research conducted at MedUni Vienna has shown how these minute particles manage to breach the blood-brainContinue reading “Mice, Men, and Nanoparticles…”

FIG. 1. (a) Sketches of the excitations of surface plasmons polaritons – SPP (top), localized surface plasmons – LSP (middle), and magnetic plasmons – MP (bottom). All these excitations are associated with a collective motion of surface charges under light illumination. (b) Diagram of MP-based plasmonic nanostructures that are used for both fundamental studies and theirContinue reading “Magnetic Plasmons in Nanostructures…”
