Apr 05, 2024 (Nanowerk News) RIKEN physicists have used ultrasonic waves to measure a magnetic material known as an antiferromagnet (Physical Review Letters, "Acoustically driven magnon-phonon coupling in a layered antiferromagnet"). This advance will make it much easier to probe its properties, boding well for the development of new devices...
Nanodevices can produce energy from evaporating tap or seawater
Apr 05, 2024 (Nanowerk News) Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the earth drives evaporative processes. Since 2017, researchers have been working to harness the energy potential of evaporation via the...
Improving infectious disease testing with gold nanoparticles
Apr 05, 2024 (Nanowerk News) By harnessing the power of composite polymer particles adorned with gold nanoparticles, a group of researchers have delivered a more accurate means of testing for infectious diseases. Details of their research was published in the journal Langmuir ("Gold Nanoparticle-Decorated Polymer (GNDP) Particles for High-Optical-Density Immunoassay...
CHEOPS detects a ‘rainbow’ on an exoplanet
Apr 05, 2024 (Nanowerk News) The CHEOPS space telescope, whose scientific operations centre is based at the University of Geneva (UNIGE), is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterised by an asymmetry between the amount of light observed on its eastern terminator - the...
Scientists develop novel method to control the geometry of chiral gold nanoparticles using copper ions
Apr 05, 2024 (Nanowerk Spotlight) Noble metal nanoparticles like gold and silver have been extensively studied for their optical, electronic, and catalytic properties, which can be finely tuned by controlling their size, shape, and composition. However, creating nanoparticles with specific geometries and desired properties has remained a significant challenge, limiting...
New micromaterial releases nanoparticles that selectively destroy cancer cells
Apr 05, 2024 (Nanowerk News) Researchers at the Universitat Autònoma de Barcelona (UAB), in collaboration with the Sant Pau Research Institute and the CIBER-BBN, have developed micromaterials made up only of proteins, capable of delivering over an extended period of time nanoparticles that attack specific cancer cells and destroy them....
First results from DESI make the most precise measurement of our expanding universe
Apr 05, 2024 (Nanowerk News) Researchers have used the Dark Energy Spectroscopic Instrument to make the largest 3D map of our universe and world-leading measurements of dark energy, the mysterious cause of its accelerating expansion. Key Takeaways DESI mapped galaxies and quasars with unprecedented detail, creating the largest 3D map...
Detecting objects without any physical interaction
Apr 05, 2024 (Nanowerk News) INL researchers have explored a fascinating quantum ability which lacks a classical explanation: the capacity to detect objects without traditional physical interaction. Rafael Wagner and Anita Camillini, INL PhD candidates, alongside the research group-leader Ernesto F. Galvão, have published a paper describing the revolutionary approach...
hexagonal building blocks are better
Apr 05, 2024 (Nanowerk News) Complex systems in nature, like their synthetic counterparts in technology, comprise a large number of small components that assemble of their own accord through molecular interactions. Gaining a better understanding of the principles and mechanisms of this self-assembly is important for the development of new...
