Dec 22, 2025 Observations of red giant R Doradus suggest stardust grains are too small for starlight to drive winds, challenging a key model. (Nanowerk News) Starlight and stardust are not enough to drive the powerful winds of giant stars, transporting the building blocks of life through our galaxy. That’s...
Universal growth conditions yield transfer-free monolayer graphene on perovskite oxides
Dec 22, 2025 Identical growth conditions yield uniform monolayer graphene on three different perovskite oxides, suggesting gas-phase chemistry enables universal fabrication without the defects that transfer methods introduce. (Nanowerk Spotlight) Stacking graphene onto perovskite oxides creates hybrid structures with electronic properties that neither material possesses alone. Graphene on strontium titanate,...
Engineered vesicles train immune cells to suppress harmful responses
Dec 22, 2025 A new class of engineered extracellular vesicles induces antigen-specific regulatory T cells, offering a targeted strategy for treating autoimmune and allergic diseases. (Nanowerk News) A research team at the Nano Life Science Institute (WPI-NanoLSI) and the Faculty of Medicine at Kanazawa University has developed a new class...
Chemists create a gold nanocluster with an open channel running through its atomic core
Dec 22, 2025 A 40-atom gold nanocluster breaks from gold's signature dense packing, forming square atomic planes with a central channel that accelerates electron relaxation about 80x. (Nanowerk Spotlight) Gold refuses to behave like other metals. It ignores oxygen, shrugs off acids that dissolve platinum, and maintains its lustrous gleam...
Washing machine filters that trap micro- and nanoplastics before they reach waterways
Dec 22, 2025 Tests show a new washing machine filter cuts polyester microfibres and captures particles down to 20 microns, helping keep plastics out of waterways. (Nanowerk News) A single laundry load containing synthetic clothing can release thousands of plastic microfibres from nylon, acrylic and polyester materials. Lab testing of...
