In water, hydrophobic molecules are surrounded by a two different water populations: the inner shell forms a two-dimensional network of water molecules.
Stress wave propagation through grainy, or granular, materials is important for detecting the magnitude of earthquakes, locating oil and gas reservoirs, designing acoustic insulation and designing materials for compacting powders.
Researchers at the Beckman Institute for Advanced Science and Technology have developed a new method to improve the detection ability of nanoscale chemical imaging using atomic force microscopy.
Picosun Group reports excellent results in ALD-organic bilayer encapsulation of metal electrodes for neuroprosthetics and bioelectronic medicine. Group also reports superior hermetic barrier performance of its ALD nanolaminates against corrosive ion diffusion in aqueous media. This is an important result for medical ALD applications and implantology, where metal components and sensitive microelectronics need to be protected against corrosion caused by human body fluids.
Whether crumbling tunnel walls, cracks in concrete facades or porous bridge piers, according to statistics from the National Association of Corrosion Engineers (NACE), damage to concrete structures caused by various environmental influences accounts for several billion euros worldwide every year.
Researchers from Basel, Bochum and Copenhagen have gained new insights into the energy states of quantum dots.
Scientists from the Center for Photonics and 2D Materials of the Moscow Institute of Physics and Technology, the University of Oviedo, Donostia International Physics Center, and CIC nanoGUNE have proposed a new way to study the properties of individual organic molecules and nanolayers of molecules.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for example in the automotive industry, because a laser operates with virtually no wear, is very fast and offers high precision.
Drones and other aircraft effectively spray pesticides over miles of crops, but the method also can pollute the environment if wind carries the mist off-target.
The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago has been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature Physics.
