new plastic is recyclable and fully ocean-degradable

Nov 26, 2024 (Nanowerk News) Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) have developed a durable plastic that won’t contribute to microplastic pollution in our oceans. The new material is as strong as conventional plastics and biodegradable, but what makes it special is...

3D-printing breakthrough mitigates three defects simultaneously for failure-free metal parts

Nov 25, 2024 (Nanowerk News) University of Wisconsin-Madison engineers have found a way to simultaneously mitigate three types of defects in parts produced using a prominent additive manufacturing technique called laser powder bed fusion. Led by Lianyi Chen, an associate professor of mechanical engineering at UW-Madison, the team discovered the...

The first-ever 2D spintronics device constructed entirely from proximitized structures

Nov 25, 2024 (Nanowerk News) Researchers from CIC nanoGUNE, in collaboration with international partners, have achieved the first seamless 2D spintronics device made entirely from proximitized structures. They report a two-dimensional graphene spin valve that is enabled by proximity to the van der Waals magnet Cr2Ge2Te6. Published in Nature Electronics...

Metafiber tips for generating optical skyrmions with subwavelength polarization features

Nov 25, 2024 (Nanowerk Spotlight) Skyrmions, known for their intricate spin textures, are topological quasiparticles initially studied in particle and solid-state physics. They hold great promise as next-generation information carriers for data storage. Recently, their photonic counterparts—optical skyrmions—have emerged as topologically structured light forms with significant potential to revolutionize optical...
