Scientists have demonstrated broadband terahertz wave generation using metamaterials. The discovery may help develop noninvasive imaging and sensing, and make possible terahertz-speed information communication, processing and storage.
Food scientist Hang Xiao is studying the biochemical fate of nanoemulsion-based food delivery systems in the gastrointestinal tract, hoping to enhance the absorption of beneficial food components encapsulated in delivery systems.
Using the interaction between light and charge fluctuations in metal nanostuctures called plasmons, a University of Arkansas physicist and his collaborators have demonstrated the capability of measuring temperature changes in very small 3-D regions of space.
A collaboration of researchers at Lawrence Berkeley National Laboratory has discovered that sodium bismuthate can exist as a form of quantum matter called a three-dimensional topological Dirac semi-metal. This is the first experimental confirmation of 3D Dirac fermions in the interior or bulk of a material, a novel state that was only recently proposed by theorists.
Highlighting the integration of nano-based engineering and medicine, the ASME (American Society of Mechanical Engineers) 2014 3rd Global Congress on Nano-engineering for Medicine and Biology (NEMB 2014) will cover the latest programs in the research community to develop advanced devices for the detection and treatment of disease.
North Carolina State University researchers have used silver nanowires to develop wearable, multifunctional sensors that could be used in biomedical, military or athletic applications, including new prosthetics, robotic systems and flexible touch panels. The sensors can measure strain, pressure, human touch and bioelectronic signals such as electrocardiograms.
