Dec 12, 2024 (Nanowerk News) For experiments that require ultra-precise measurements and control over atoms — think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates — lasers are the technology of choice, the more spectrally pure (emitting a single color/frequency), the better. Conventional lab-scale laser technology currently achieves this...
Superflares once per century
Dec 12, 2024 (Nanowerk News) There is no question that the Sun is a temperamental star, as alone this year’s unusually strong solar storms prove. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious? Evidence of the most violent solar...
Hydrogel robots for targeted drug delivery
Dec 11, 2024 (Nanowerk News) In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres. Such robots would have a long and challenging list of...
Researchers discover new third class of magnetism that could transform digital devices
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...
Groundbreaking research unveils unified theory for optical singularities in photonic microstructures

This research presents a unified theoretical scheme that sheds light on...
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...
