Mar 11, 2024 (Nanowerk News) Researchers at Tohoku University have addressed one of the key challenges of electromagnetic waves in the terahertz frequency range by developing a new type of tuneable filter for signals in the terahertz wave band. Electromagnetic waves in the terahertz frequency range offer many advantages for...
Paper AI sensor mimics brain for health monitoring
Mar 11, 2024 (Nanowerk News) From creating images, generating text, and enabling self-driving cars, the potential uses of artificial intelligence (AI) are vast and transformative. However, all this capability comes at a very high energy cost. For instance, estimates indicate that training OpenAI's popular GPT-3 model consumed over 1,287 MWh,...
Design rules and synthesis of quantum memory candidates
Mar 11, 2024 (Nanowerk News) In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those...
Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists
Mar 11, 2024 (Nanowerk News) When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the "Hubble Tension," is that the current rate of the expansion of the universe is faster than what astronomers expect it to be,...
Breakthrough LCD tech creates full-color dynamic hologram displays
Mar 11, 2024 (Nanowerk Spotlight) Holography, the technique of using light to reconstruct three-dimensional images, has long captured the imagination of scientists and the public alike. By recording and later recreating the complete waveform of light reflected off an object, holograms can display images that shift and change perspective based...
Combined microscopy technique catches light-driven polymers in the act
Mar 11, 2024 (Nanowerk News) Expanding our scientific understanding often comes down to getting as close a look as possible at what is happening. Now researchers from Japan have observed the nanoscale behavior of azo-polymer films while triggering them with laser light. In a study published in Nano Letters ("In-situ...
Quantum-mechanical ‘molecules’ spotted in superconducting devices
Mar 11, 2024 (Nanowerk News) Electronic states that resemble molecules and are promising for use in future quantum computers have been created in superconducting circuits by physicists at RIKEN (Nature Communications, "Phase-dependent Andreev molecules and superconducting gap closing in coherently-coupled Josephson junctions"). The most obvious advantage of superconductors – materials...
A simple and robust method to add functional molecules to peptides
Mar 11, 2024 (Nanowerk News) Peptides are short strands of amino acids that are increasingly used therapeutically, as biomaterials and as chemical and biological probes. The capacity to isolate, manipulate and label peptides and larger proteins is limited, however, by the ability to reliably attach functional molecules, such as fluorescent...
