Flexible nanoimprint lithography enables efficient fabrication of biomimetic microstructures The common projection lithography methods are very sensitive to the shape of the substrate, so the accuracy of microstructure definition may be reduced when the substrate has large warps or irregular shapes. Researchers from Wuhan University propose a flexible nanoimprint lithography technique that enables high-throughput and high-quality processing of bionic microstructures on curved surfaces. https://lnkd.in/gX5-BcNY #nanotechnology #biotechnology #lithography #materials #3dprinting #electronics #technology #engineering

FSU researchers identify unique phenomenon in Kagome metal The researchers identified for the first time the existence of plasmons in CsV3Sb5 and found that the wavelength of those plasmons depends upon the thickness of the metal. https://lnkd.in/gp5umhss #nanotechnology #materialsscience #quantum #engineering #electronics #photonics #scienceandtechnology

Nonlinear encoding in diffractive optical processors based on linear materials The UCLA research team, led by Professor Aydogan Ozcan, evaluated various nonlinear encoding strategies using different datasets to assess their statistical inference performance. Their findings revealed that data repetition within a diffractive volume, while enhancing inference accuracy, compromises the universal linear transformation capability of diffractive optical processors. As a result, data repetition-based diffractive blocks cannot serve as optical analogs to fully-connected or convolutional layers commonly used in digital neural networks. https://lnkd.in/gYgn3WfP #nanotechnology #photonics #optics #materials #electronics #technology #engineering

Researchers study cicadas’ antimicrobial properties to develop new antibacterial surfaces When microbes land or move on the nanopillars, their outer membrane becomes damaged. Microbial contamination threatens cicadas and is a prevalent issue in human society: in shipping industries, underwater pipelines, medical implants and other devices and appliances. https://lnkd.in/gtQfhkvb #nanotechnology #biotechnology #materials #lifesciences #technology #medicine #innovation

Reducing electronic waste with biodegradable luminescent polymers At the end of life, this new polymer can be degraded under either mild acidic conditions (near the pH of stomach acid) or relatively low heat treatment (> 410 F). The resulting materials can be isolated and remade into new materials for future applications. https://lnkd.in/gKMcv7mr #nanotechnology #innovation #greentech #electronics #engineering #materialsscience

AI method radically speeds predictions of materials’ thermal properties It is estimated that about 70 percent of the energy generated worldwide ends up as waste heat. If scientists could better predict how heat moves through semiconductors and insulators, they could design more efficient power generation systems. However, the thermal properties of materials can be exceedingly difficult to model. https://lnkd.in/g38X66Rd #nanotechnology #materialsscience #advancedmaterials #engineering #electronics #AI #technology #scienceandtechnology

Paving the way to extremely fast, compact computer memory For decades, scientists have been studying a group of unusual materials called multiferroics that could be useful for a range of applications including computer memory, chemical sensors and quantum computers. In a study published in Nature, researchers from The University of Texas at Austin and the MPSD in Hamburg have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices that are extremely fast and compact. https://lnkd.in/gWA52sp8 #nanotechnology #computing #materials #electronics #engineering #technology #innovation

Metamaterials for the data highway 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 reports in the journal Advanced Electronic Materials, these findings could pave the way for novel types of data storage and sensors, including even magnetic variants of neural networks. https://lnkd.in/g-VkUYHc #nanotechnology #innovation #data #scienceandtechnology #electronics #engineering #sensors

Mapping the surfaces of MXenes atom by atom reveals new potential for the 2D materials Using advanced imaging techniques, known as scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS), the team, which also includes researchers from California State University Northridge, and Lawrence Berkeley National Laboratory, mapped the electrochemical surface topography of the titanium carbide MXene — the most-studied and widely used member of the family. Their findings, published in the 5th anniversary issue of the Cell Press journal Matter, will help to explain the range of properties exhibited by members of the MXene family and allow researchers to tailor new materials for specific applications. https://lnkd.in/gQFe_FcR #nanotechnology #materialsscience #mxenes #2dmaterials #electronics #engineering #technology #microscopy #spectroscopy #chemistry

SLAC’s high-speed electron camera uncovers a new ‘light-twisting’ behavior in an ultrathin material The ultrathin material was a mere 50 nanometers thick. This is 1,000 to 10,000 times thinner than what we typically need to induce this type of response. This work represents another element in our toolbox for manipulating terahertz light fields, which in turn could allow for new ways to control materials and devices in interesting ways. https://lnkd.in/gD29XcT2 #nanotechnology #materialsscience #2dmaterials #electronics #engineering #technology
