Jun 08, 2022 (Nanowerk News) A team of Brown University researchers has developed a new responsive material that is able to release encapsulated cargo only when pathogenic bacteria are present. The material could be used to make wound dressings that respond quickly to burgeoning infections, but only deliver medication on-demand....
Experiments in twisted, layered quantum materials offer new picture of how electrons behave
Jun 08, 2022 (Nanowerk News) A recent experiment detailed in the journal Nature ("One-dimensional Luttinger liquids in a two-dimensional moiré lattice") is challenging our picture of how electrons behave in quantum materials. Using stacked layers of a material called tungsten ditelluride, researchers have observed electrons in two-dimensions behaving as if...
Strange radio burst raises new questions
Jun 08, 2022 (Nanowerk News) Astronomers have found only the second example of a highly active, repeating Fast Radio Burst (FRB) with a compact source of weaker but persistent radio emission between bursts. The discovery raises new questions about the nature of these mysterious objects and also about their usefulness...
Sponge-like solar cells could be basis for better pacemakers
Jun 08, 2022 (Nanowerk News) Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn’t be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter. In a new study, University of...
Researchers can customize cavities in new porous material
Jun 08, 2022 (Nanowerk News) Researchers at the University of Gothenburg have produced a porous and stable material in which the cavities can be used to store various substances. The material can be used both in the pharmaceutical industry and for filtration at the molecular level. Porous materials are very...
Microbubble technology enhances cancer immunotherapy
Jun 08, 2022 (Nanowerk News) Researchers at UT Southwestern have developed a first-of-its-kind ultrasound-guided cancer immunotherapy platform that delivers immune-stimulating agents to cells for the development of systemic anti-tumor immunity. The technology, termed Microbubble-assisted Ultrasound-guided Immunotherapy of Cancer (MUSIC), was described in a study published in Nature Nanotechnology ("Cancer immunotherapy...
Fuel-cell waste reduction goes platinum
Jun 08, 2022 (Nanowerk News) Fuel cells generate electricity from hydrogen, a “clean” fuel that produces only water when burned. Platinum is a key catalyst in this process. However, platinum degrades unevenly in fuel cells, resulting in still-usable platinum being discarded when “worn out” fuel cells are replaced. To improve...
Nanosensor detects pesticides on fruit in minutes
Jun 07, 2022 (Nanowerk News) Researchers at Karolinska Institutet in Sweden have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique, described as a proof-of-concept in a paper in the journal Advanced Science ("SERS Hotspot Engineering by Aerosol Self-Assembly of Plasmonic Ag Nanoaggregates...
Yolk-shell nanocrystals with movable gold yolk: Next generation of photocatalysts
Jun 07, 2022 (Nanowerk News) Owing to their unique permeable, hollow shell structures with inner, movable cores, yolk-shell nanocrystals are suitable for a wide variety of applications. Yolk-shell nanocrystals consisting of a gold core with various semiconductor shells have been developed by Tokyo Tech researchers, using a novel sequential ion-exchange...
Investigating electrons with a traditional scanning microscope
Jun 07, 2022 (Nanowerk News) Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. The procedure is considerably cheaper than the technology that has been used to date, and also enables a wider range...
