Researchers are using a technique they developed to observe minute distortions in the atomic structure of complex materials, shedding light on what causes these distortions and opening the door to studies on how such atomic-scale variations can influence a material's properties.
A production facility for start-ups in the field of nanotechnology may be built in the Science Village in Lund, a world-class research and innovation village that is also home to ESS, the European Spallation Source.
Since 2012, the NanoMICEX project has been investigating ways to mitigate the risk and control workers' exposure to nanomaterials used in the inks and pigments industry. The project is nearing completion, and it is keen to share its knowledge with industrial stakeholders, scientists and policy-makers on how it has mitigated risks commonly faced in the sector.
Interest in the use of engineered nanomaterials (ENMs) as either nanomedicines or dental materials/devices in clinical dentistry is growing. This new review paper details the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks.
Scientists have shown that gold nanotubes have many applications in fighting cancer: internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells. A new study details the first successful demonstration of the biomedical use of gold nanotubes in a mouse model of human cancer.
Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers propose a new type of transistor made from these materials.
Atom probe tomography, a powerful atomic-scale microscopy and micro-analysis technique, allowed researchers to make out the enamel's nanoscale composition and structure. This research identified never-before-seen amorphous biominerals and how they contribute to both mechanical hardness and the resistance of enamel to acid dissolution.
New research looks at how to create various non-spherical particles by releasing droplets of molten wax into a cool liquid bath. The physics behind this research shows how a range of non-spherical shapes can be produced and replicated with many possible industrial applications.
