Porous particles of calcium and silicate show potential as building blocks for a host of applications. A Rice University laboratory tested calcium-silicate particles to see how they hold up under pressure and found that size influenced the toughness of individual particles but not assemblies.
Scientists designed the first subwavelength dielectric resonators for light trapping at the nanoscale that appears to be the simple silicon cylinder hundred times thinner than a human hair. Such a structure is capable to trap light ten times longer than any conventional resonator. Along with a simple shape and small size, it makes this new resonator a promising basis for a design of powerful nanolasers, biosensors, and various light transmitting devices. The results were published in Physical Review Letters.
A 'quantum material' that mimics a shark's ability to detect the minute electric fields of small prey has been shown to perform well in ocean-like conditions, with potential applications from defense to marine biology.
By encapsulating bilirubin within tiny nanoparticles, researchers from North Carolina State University and the Ohio State University have improved the survival rates of pancreatic islet cells in vitro in a low-oxygen environment. The work has implications for the treatment of Type 1 diabetes in both canine and human patients.
Graphene Flagship scientists, led by researchers at ICFO -- The Institute of Photonic Sciences in Barcelona, Spain, have detected graphene's out-of-plane heat transfer in van der Waals heterostructures. In their paper published in Nature Nanotechnology they follow this process in real-time. This phenomenon has many implications for optoelectronic devices.
Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene -- each one-atom thick -- could be made to transform into a diamond-like material upon impact at room temperature.
Engineers have shown that a widely used method of detecting single photons can also count the presence of at least four photons at a time. The researchers say this discovery will unlock new capabilities in physics labs working in quantum information science around the world, while providing easier paths to developing quantum-based technologies.
In a research article '3D Nano-scale Imaging by Plasmonic Brownian Microscopy' published today in Nanophotonics, the team around Prof. Xiang Zhang from the University of California in Berkeley demonstrate a method for meeting this challenge with stunning properties.
An international team of scientists, from the University of Surrey, University of São Paulo (Brazil), the University of Warwick and the University of Grenoble-Alpes (France), has created a new metal-organic framework (MOF) that has shown record-high photo-conductivity levels for a material of its type.
A physicist from Siberian Federal University (SFU) and Kirensky Institute of Physics Federal Research Center KSC SB RAS (IF) described the structure and properties of a new substance obtained by his Chinese colleagues. These are layered crystals of rare earth metal hydroxides Ln2(OH)4SO4 (Ln=Eu-Lu, Y) that may acts as eco-friendly sources of phosphors (substances that transform different energies into emission of light) for panels, screens, and other electronic devices. The discovery was reported by Chemistry: A European Journal.
