Dec 12, 2024 (Nanowerk News) A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times. Altermagnetism is...
Novel MOF materials with almost perfect water repellency
Dec 12, 2024 (Nanowerk News) Scientists from Karlsruhe Institute of Technology (KIT) and the Indian Institute of Technology Guwahati (IITG) have developed a surface material that repels water droplets almost completely. Using an entirely innovative process, they changed metal-organic frameworks (MOFs) – artificially designed materials with novel properties – by...
reversible sliding motion in ammonium-linked ferrocene
Dec 12, 2024 (Nanowerk News) Artificial molecular machines, nanoscale machines consisting of a few molecules, offer the potential to transform fields involving catalysts, molecular electronics, medicines, and quantum materials. These machines operate by converting external stimuli, like electrical signals, into mechanical motion at the molecular level. Ferrocene, a special drum-shaped...

Exploring microtubule lattice at submolecular resolution
Dec 12, 2024 (Nanowerk News) In a study recently published in the journal Nano Letters ("Visualizing the Submolecular Organization of αβ-Tubulin Subunits on the Microtubule Inner Surface Using Atomic Force Microscopy"), researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, Kanazawa, Japan, used frequency-modulated atomic force microscopy to reveal the...
Scientists create customizable 3D-printed radiation detectors with perovskite materials
Dec 12, 2024 (Nanowerk Spotlight) When a patient receives radiation therapy for cancer treatment, doctors must carefully control the radiation dose to target tumor cells while sparing healthy tissue. This requires precise monitoring of radiation patterns in three dimensions. However, current radiation detectors, which convert radiation into measurable light signals,...
Astronomers discover magnetic loops around supermassive Black Hole
Dec 12, 2024 (Nanowerk News) NGC 1068 is a well-known, relatively nearby, bright galaxy with a supermassive black hole at its center. Despite its status as a popular target for astronomers, however, its accretion disk is obscured by thick clouds of dust and gas. A few light-years in diameter, the...
Nanofluidic devices redefining matter manipulation at an unprecedented level
Dec 12, 2024 (Nanowerk News) One of the great ambitions in the scientific world is to use tiny objects – such as molecules, viruses, and nanoparticles – as building blocks to construct essential macromolecules and materials, much like constructing intricate designs with LEGO bricks. However, achieving this requires overcoming significant...
A black hole jet stumbles into something in the dark (w/video)
Dec 12, 2024 (Nanowerk News) Even matter ejected by black holes can run into objects in the dark. Using NASA’s Chandra X-ray Observatory, astronomers have found an unusual mark from a giant black hole’s powerful jet striking an unidentified object in its path. A paper describing these results appears in...
Fast, rewritable computing with DNA origami registers
Dec 12, 2024 (Nanowerk News) DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are faster and smaller than today’s silicon-based versions. As...
