Lead-free ceramic capacitors reach high energy density at moderate fields
Apr 29, 2026 Polarizable nanodomains in lead-free BNT ceramics overcome the trade-off between energy storage density and efficiency at moderate electric fields. (Nanowerk News) A team of materials scientists has engineered a lead-free bismuth sodium titanate (BNT)-based ceramic that achieves both high recoverable energy storage density and high efficiency at...
what works, what is early, and what is hype
Apr 29, 2026 Our evidence guide separates real nano-enabled biohacking from marketing claims, from glucose sensors and nanoformulations to peptides and smart materials. (Nanowerk Spotlight) Biohacking sells itself as control: track more signals, tune more pathways, recover faster, age more slowly. The promise is seductive because it sounds measurable. But...
The most common planets in the galaxy don’t appear around the most common stars
Apr 29, 2026 New research finds the galaxy's most common stars host many super-Earths but almost no sub-Neptunes, reshaping planet formation theories. (Nanowerk News) Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our...
New nitride magnets let electricity flip hidden spin patterns
Apr 29, 2026 New nitride materials could let electricity control hidden magnetic spin patterns, pointing toward faster and more stable future electronics. (Nanowerk Spotlight) A material used to store information must satisfy a demanding bargain. It has to keep its state when the power is off, resist noise from its...
New roadmap highlights surface acoustic wave technologies
Apr 29, 2026 A new roadmap charts the next decade for surface acoustic wave technology, spanning signal processing, quantum tech, and life sciences applications. (Nanowerk News) The application of surface acoustic waves is widespread. The spectrum ranges from modern communication technologies, for example wireless data transmission with smartphones, to the...
Nanozymes against brain tumors
Apr 29, 2026 Researchers are developing nanozymes that can attack brain cancer cells directly during tumor surgery, offering new hope when conventional therapies fall short. (Nanowerk News) Among malignant brain tumors, astrocytoma is particularly common and equally dangerous: Surgical removal of this aggressively growing tumor can be difficult because the...
Nano-tin interlayer solves interfacial instability in all-solid-state batteries
Apr 29, 2026 Researchers developed a nano-tin interlayer that stabilizes solid-state battery interfaces, achieving 350 Wh/kg energy density and 81% capacity retention over 500 cycles.
