Mar 18, 2022 (Nanowerk News) When it comes to porous metamaterials – ubiquitous, sponge-like materials used in everything from sound absorption to self-cleaning glass – it’s all about how you slice it. In a new paper from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and...
Researchers develop the world’s first power-free frequency tuner using nanomaterials (w/video)
Mar 18, 2022 (Nanowerk News) In a paper published in Nature Communications ("Real-time nanomechanical property modulation as a framework for tunable NEMS"), researchers at the University of Oxford and the University of Pennsylvania have found a power-free and ultra-fast way of frequency tuning using functional nanowires. Think of an orchestra...
Three space station studies helping scientists understand the early universe
Mar 18, 2022 (Nanowerk News) Research conducted aboard the International Space Station is helping scientists answer questions about the formation of the universe and origins of life on Earth. During its 21 years of operation, the orbiting lab has hosted more than 3,000 scientific experiments aimed at helping improve life...
Turning any camera into a polarization camera
Mar 18, 2022 (Nanowerk News) Polarization, the direction in which light vibrates, provides a lot of information about the objects with which it interacts, from aerosols in the atmosphere to the magnetic field of stars. However, because this quality of light is invisible to human eyes, researchers and engineers have...
New insight into the possible origins of life
Mar 18, 2022 (Nanowerk News) Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity, following Darwinian evolution. This has provided the first empirical evidence that simple biological molecules can lead to the emergence of complex...
Are 2D interfaces really completely flat?
Mar 18, 2022 (Nanowerk News) When two or more atomically thin sheets of materials – like graphene – are placed on top of each other, their properties change and a material with novel hybrid properties emerges. The in-plane stability of the individual 2D materials is provided by strong covalent bonds....
Gene regulation at its brightest
Mar 18, 2022 (Nanowerk News) Tohoku University scientists in Japan have developed a virus-based approach for measuring variations in gene regulatory elements, called transcription factors, as conditions change in live organisms. The research, published in the journal iScience ("PCR-based profiling of transcription factor activity in vivo by a virus-based reporter...
Magnet-free chiral nanowires for spintronic devices
Mar 18, 2022 (Nanowerk News) Researchers from the Basque Nanoscience Research Center CIC nanoGUNE (San Sebastian, Spain), in collaboration with POLYMAT (San Sebastian, Spain), the Institute of Physics of the Martin Luther University Halle-Wittenberg and the Max Planck Institute of Microstructure Physics (both in Halle, Germany) demonstrate the all-electrical generation,...
With machine learning to new supramolecular materials
Mar 17, 2022 (Nanowerk News) A team of scientists at the TUM Innovation Network ARTEMIS (Artificial Intelligence Powered Multifunctional Material Design), named after the Greek goddess of hunting, are researching supramolecular materials. They are investigating their use in medicine and energy production supported by machine learning. “The idea of ARTEMIS...
Web3 technology puts farmers in charge of their data
Mar 17, 2022 (Nanowerk News) Innovations such as Web3, the third generation of the internet, and easy-to-use video-based technologies in local languages have the potential to drive change in agriculture in developing countries, say technology advocates. Web3, which refers to efforts to create a decentralised version of the internet based...
