Researchers used a unique optical metamaterial with a refractive index of zero to generate 'phase mismatch-free nonlinear light', meaning the generated light waves move through the material gaining strength in all directions. This phase mismatch-free quality holds promise for quantum computing and networking, and future light sources based on nonlinear optics - the phenomena that occur when interactions with light modify a material's properties.
Scientists from NIST and Sandia National Laboratories have added something new to a family of engineered, high-tech materials called metal-organic frameworks: the ability to conduct electricity. Conductive MOFs have the potential for use in a variety of applications including sensors for detecting gases and toxic substances.
Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division in collaboration with researchers at University at Buffalo-The State University of New York (SUNY) demonstrate the possibility for new optical devices using graphene for communications, imaging and signal processing.
A revolutionary instrument that will expedite the discovery of new, artificial forms of matter with unprecedented electronic and magnetic properties will be funded by a $4.13 million gift from the Gordon and Betty Moore Foundation.
Researchers have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. This development will have future implications in the guided delivery of oil and effective blockage of oil spreading.
An international, multidisciplinary research team has developed an ultrathin membrane that can stick to skin and carry arrays of diagnostic sensors and stimulatory components. The 'electronic skin' allows remote patient monitoring and may someday be used to deliver treatments.
A tiny capsule that can carry out a chemical analysis of the contents of one's stomach could identify the presence of so-called 'occult' blood at very low levels. The data is automatically broadcast to an external monitoring device for detection of early stage stomach cancer by one's physician.
Scientists are reporting development of a squishy gel that when compressed - like at a painful knee joint - releases anti-inflammatory medicine. The new material could someday deliver medications when and where osteoarthritis patients need it most.
A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions.
If the promise of nanotechnology is to be fulfilled, then research programs must leapfrog to new nanomanufacturing processes. That's the conclusion of a review of the current state of nanoscience and nanotechnology.
Accurate and reliable measurement of volatile organic compounds (VOCs) is an important need in many application areas in industry, air pollution and atmosphere, health and well-being, defense and security as well as in many other fields. In a new thesis, cantilever-enhanced photoacoustic spectroscopy has been applied for the measurement of VOCs.
In light of debates that make nanotechnologies responsible for a further widening of the aforementioned divide, this new report analyses this Nano-Gap, or Nano-Divide, by examining the pros and cons of nanotechnologies and their impact global development and the on-going fight against poverty.
