| Three-dimensional metamaterials with a natural bent Posted: 24 Oct 2014 05:26 AM PDT Scientists have succeeded in creating a large metamaterial, up to 4 mm x 4 mm2 in size, that is essentially isotropic, using a type of metamaterial element called a split-ring resonator. |
| First protein microfiber engineered: New material advances tissue engineering and drug delivery Posted: 23 Oct 2014 08:10 AM PDT Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale -- a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers. |
| Waste, an alternative source of energy to petroleum Posted: 23 Oct 2014 06:10 AM PDT The development of sustainable refineries is the focus of recent research, where it is possible to produce fuels and raw materials providing an alternative to petroleum by using biomass and other waste materials like plastics, tires, etc. Conical spouted beds are the key to the high energy efficiency of these refineries. |
| Polymer hybrid thin-film composites for food packaging and membrane filters Posted: 23 Oct 2014 06:10 AM PDT Researchers have developed new hybrid materials for use in the manufacture and modification of thin-film composites. The project resulted in new materials suitable for instance for food packaging with enhanced diffusion barrier and for membrane filters with improved anti-fouling properties used in water purification. In the future, similar materials may find use in flexible OLED displays and in wall and ceiling panels. |
| Quantum effects bridge the gap Posted: 23 Oct 2014 06:07 AM PDT Quantum effects in nanometer-scale metallic structures provide a platform for combining molecular electronics and plasmonics. |
| Adaptive zoom riflescope prototype has push-button magnification Posted: 22 Oct 2014 09:30 AM PDT A prototype Rapid Adaptive Zoom for Assault Rifles (RAZAR) has been developed. At the push of a button, RAZAR can toggle between high and low magnifications, enabling users to zoom in without having to remove their eyes from their targets or their hands from their rifles. The RAZAR prototype uses a patented active optical zoom system, called "adaptive zoom." |
