Billions of smartphone owners are familiar with the dreaded "low battery" symbol on their devices. While consumers groan, scientists are working to understand why and when lithium-ion batteries in phones, plug-in electric ...
Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is instability ...
A team led by scientists at the University of Washington has designed and tested a 3-D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science ...
Modern electronics is based on doped semiconductors. To synthesize electronic components, dopant atoms such as aluminum or phosphorus are embedded into crystals of ultrapure silicon. This allows for tailoring semiconductor ...
Researchers have developed advanced optical security features that use a two-piece metamaterial system to create a difficult-to-replicate optical phenomenon. Metamaterials are engineered to have a property that is not found ...
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a new way to measure distances at the nanoscale—one nanometer being one billionth of a meter—using light.
Tip-enhanced Raman spectroscopy resolved "resonance" Raman scattering with 1-nm resolution in ultrathin zinc oxide films epitaxially grown on a single-crystal silver surface. Tip-enhanced "resonance" Raman scattering can ...
Nucleation is the formation of a new condensed phase from a fluid phase via self-assembly. This process is critical to many natural systems and technical applications including the manufacturing of pharmaceuticals and advanced ...
Missouri S&T researchers are demonstrating a new concept to reconstruct holographic images by using a single two-dimensional material monolayer with the thickness of less than one nanometer. Their work could lead to the creation ...
The first gravity maps of the GRACE-FO mission are now available. The twin satellites of the GFZ German Research Centre for Geosciences and NASA continuously measure the Earth's gravitational field and thus carry on the successful ...
