Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material
Jul 16, 2024 (Nanowerk News) Industrial emissions are one of the main sources of climate change-inducing carbon dioxide (CO2). While adopting renewable and clean energy alternatives is one option for mitigating these carbon emissions, carbon capture technology is another solution to control CO2 emissions. In big CO2-emitting industries, such as...
A new metamaterial concept offering the potential for more efficient data storage
Jul 16, 2024 (Nanowerk News) Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Chemnitz, TU Dresden and Forschungszentrum Jülich have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers. As the team...
Researchers achieve unprecedented nanostructuring inside silicon
Jul 16, 2024 (Nanowerk News) Silicon, the cornerstone of modern electronics, photovoltaics, and photonics, has traditionally been limited to surface-level nanofabrication due to the challenges posed by existing lithographic techniques. Available methods either fail to penetrate the wafer surface without causing alterations or are limited by the micron-scale resolution of...
Breakthrough in quantum computing components with atomically thin transducers
Jul 15, 2024 (Nanowerk News) Quantum computers have to be kept cold to function — very cold. These machines generally run at “just a few degrees above absolute zero,” says Yoseob Yoon, assistant professor of mechanical and industrial engineering at Northeastern University. “It’s colder than outer space.” Yoon’s research focuses...
New model unveils galaxy color-distance relationship for measuring cosmic structures
Jul 15, 2024 (Nanowerk News) Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our telescopes in the night sky: galaxies like our own Milky Way, clusters of galaxies, and...
Polymer library for RNA-based therapeutic approaches
Jul 15, 2024 (Nanowerk News) RNA therapy with polymer nanoparticles is considered a promising approach for the treatment of various illnesses. It involves the use of polymers as “nanocarriers” to transport RNA drugs precisely to the correct target cells. Manufacturing such polymers, however, has proven to be complex and difficult....
New techniques enhance brightness and control of quantum defects in nanodiamonds
Jul 15, 2024 (Nanowerk Spotlight) The quest to harness the power of quantum mechanics for practical applications has been a driving force in physics and materials science. At the heart of this endeavor lies the challenge of creating and manipulating quantum systems that can operate reliably at room temperature. While...
Structured electrons with chiral mass and charge
Jul 13, 2024 (Nanowerk News) Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons. The electrons are shaped into chiral coils of mass and charge. Such engineered elementary particles may open new research avenues in fundamental physics and electron microscopy....
Atomically controlled MXenes enable cost-effective green hydrogen production
Jul 15, 2024 (Nanowerk News) 137 countries around the world have signed a "net-zero" climate change agreement to end fossil fuel use and achieve zero carbon emissions by 2050. Hydrogen is being touted as the next green energy source because it emits only water and oxygen when utilized as an...
