Downscaling storage devices with chiral spiral magnets

Mar 22, 2024 (Nanowerk News) A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, non-volatility, and high durability. Details of their findings were published in the journal Nature Communications ("Room temperature chirality switching...

Direct laser writing on halide perovskites: from mechanisms to applications

Mar 22, 2024 (Nanowerk News) Metal halide perovskites have become well-deserved “star” materials among a variety of semiconductors owing to their excellent optoelectronics properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable bandgaps, long carrier diffusion lengths, and high defect tolerance, attracting enormous attention from both...

Plasmonic water safety detector for toxic substances

Mar 22, 2024 (Nanowerk News) Pharmaceutical waste and contaminants present a growing global concern, particularly in the context of drinking water and food safety. Addressing this critical issue, a new study by researchers at Bar-Ilan University’s Department of Chemistry and Institute of Nanotechnology and Advanced Materials has resulted in the...

An endless domino effect (w/video)

Mar 21, 2024 (Nanowerk News) If it walks like a particle, and talks like a particle… it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like...

Understanding corrosion to enable next-generation metals

Mar 21, 2024 (Nanowerk News) Researchers are using new, experimental techniques like Shear Assisted Processing and Extrusion (ShAPE™) and friction stir welding to produce metal components that are lighter, stronger, and more precise than ever before. But as we enter those new frontiers of metalworking, it’s crucial to understand the...

Is greenhouse farming releasing microplastics into water?

Mar 21, 2024 (Nanowerk News) In a recent study conducted by INL researchers, in collaboration with University of Alcalá, Madrid, it has been revealed that greenhouse plastic cover films, commonly composed of polyethylene (PE), are releasing microplastics into the environment during their usage, significantly impacting ecosystems. Microplastics are tiny plastic...

Moebius rings enable new ways to control light in twisted spaces

Mar 21, 2024 (Nanowerk Spotlight) The field of topological photonics has witnessed remarkable progress over the past decade, providing a robust platform for studying light-matter interactions and enabling the development of novel optical devices. However, the ability to control and modulate topological phase transitions has remained a significant challenge, particularly...
