Mar 04, 2024 (Nanowerk News) Credit cards embedded chips, national mints printed watermarks, and high-profile locations installed retina scanners all for the same reason—to protect information. As attackers grow smarter, so must defense. Sheng Shen, along with collaborators at Penn State University, have developed a pixel-by-pixel approach to visible camouflage...
Network of quantum sensors boosts precision
Mar 04, 2024 (Nanowerk News) Quantum sensor technology promises even more precise measurements of physical quantities. A team led by Christian Roos at the University of Innsbruck has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions...
Revolutionizing programmable metasurfaces with wireless power transfer
Mar 04, 2024 (Nanowerk Spotlight) Programmable metasurfaces have shown great potential for advanced electromagnetic wave manipulation in wireless communications, sensing, and other applications. However, a major limitation has persisted – the need for cumbersome wired DC power connections to supply control circuitry embedded in these metasurfaces. This has hampered adoption,...
Novel nanosheet method revolutionizes brain imaging for multi-scale and long-term studies
Mar 04, 2024 (Nanowerk News) The human brain has billions of neurons. Working together, they enable higher-order brain functions such as cognition and complex behaviors. To study these higher-order brain functions, it is important to understand how neural activity is coordinated across various brain regions. Although techniques such as functional...
Nanothin printing of electronics hardware could slash costs

The process comes amid increasing worldwide demand for memory devices, which require...
Nanoscale topcoat can turbocharge supported gold nanoparticle catalysts
Mar 02, 2024 (Nanowerk News) Researchers from Tokyo Metropolitan University have developed a way to add single nanosheets of mixed metal oxide to gold nanoparticles supported on silica to enhance their catalytic activity. Converting carbon monoxide to carbon dioxide, they found that the temperature required for the reaction was greatly...
The first protective layer for 2D quantum materials
Mar 01, 2024 (Nanowerk News) As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers at the Würzburg-Dresden Cluster of Excellence ct.qmat...
Astronomers reveal a new link between water and planet formation
Mar 01, 2024 (Nanowerk News) Researchers have found water vapour in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never...
Building bionic jellyfish for ocean exploration (w/video)
Mar 01, 2024 (Nanowerk News) Jellyfish can't do much besides swim, sting, eat, and breed. They don't even have brains. Yet, these simple creatures can easily journey to the depths of the oceans in a way that humans, despite all our sophistication, cannot. But what if humans could have jellyfish...
Faster charging with diamond nanomembranes
Mar 01, 2024 (Nanowerk News) Diamond is known for its outstanding thermal conductivity. This makes the material ideal for cooling electronic components with high power densities, such as those used in processors, semiconductor lasers or electric vehicles. Researchers at Fraunhofer USA, an independent international affiliate of the Fraunhofer-Gesellschaft, have succeeded...
