Sustainable battery electrode material derived from tea waste
Jan 30, 2024 (Nanowerk Spotlight) The transition to renewable wind and solar power faces a pivotal roadblock in the lack of affordable large-scale energy storage options. Without cost-effective grid-level batteries, fluctuation and intermittency issues make widespread adoption of sustainable generation impractical. After promising strides reducing production expenses for components like...
Researchers seek to understand how regions of ‘cosmic web’ influence behavior of galaxies
Jan 30, 2024 (Nanowerk News) Researchers at the University of Kansas hope to better understand intricate mechanisms behind the evolution of galaxies, which travel through a “cosmic web” of different environments during their lifespans. Gregory Rudnick, professor of physics & astronomy at KU, is leading a team that recently earned...
At the nanoscale, meteorite reveals clues to origin of life on Earth
Jan 30, 2024 (Nanowerk News) Meteorites represent the building blocks of the solar system, providing key insights into the ingredients from which the planets, including our own, are formed. Research using powerful microscopes, conducted by collaborating institutions - including the University of Leeds - has now helped to further that...
Structural color ink: Printable, non-iridescent and lightweight
Jan 30, 2024 (Nanowerk News) An object has color when light of a specific wavelength is reflected. With traditional pigments, this happens by molecules absorbing other colors from white light, but over time this interaction makes the molecules degrade and the color fades. Structural colors, on the other hand, usually...
DNA particles that mimic viruses hold promise as vaccines
Jan 30, 2024 (Nanowerk News) Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2. The vaccine, which has been tested in mice, consists of a DNA...
A manifold fitting approach for high-dimensional data reduction beyond Euclidean space
Jan 29, 2024 (Nanowerk News) National University of Singapore (NUS) statisticians have introduced a new technique that accurately describes high-dimensional data using lower-dimensional smooth structures. This innovation marks a significant step forward in addressing the challenges of complex nonlinear dimension reduction. Traditional data analysis methods often rely on Euclidean (linear)...
Quantum frustration in 3D crystal freezes electron motion
Jan 30, 2024 (Nanowerk News) Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place. The find is detailed in a study published in Nature...
Cosmic building blocks of life discovered through the electron microscope
Jan 29, 2024 (Nanowerk News) Meteorites are fragments of asteroids which find their way to Earth as shooting stars. These cosmic sediments have frozen the primordial soup from which our solar system emerged – preserving it just like a time capsule. These rocks help researchers to get to the bottom...
