University of Washington engineers hope a new type of vaccine they have shown to work in mice will one day make it cheaper and easy to manufacture on-demand vaccines for humans. Immunizations could be administered within minutes where and when a disease is breaking out.
Invisibility has become a scientific possibility with the emergence of metamaterials and transformation optics in the past few years. A recent paper reviewed design methodologies and experimental developments of the invisibility cloak from a practical perspective. The recent transition from a forward cloaking design to inverse cloaking design was also addressed.
Recently, the emergence of a design strategy called transformation optics has provided a completely new way to control light on all length scales, opening new doors to many unprecedented optical functions. A new paper has reviewed the recent progress made using this revolutionary technology in the design of efficient plasmonic light-harvesting devices.
Newly emerging flu viruses could soon be countered by a treatment that Draper Laboratory is developing that 'traps' viruses before they can infect host cells. Further into the future, patients suffering from any type of virus could be cured with DRACO, a drug also under development at Draper that is designed to rapidly recognize and eliminate cells infected by virtually any virus.
The sensors team at DOE's National Energy Technology Laboratory is working on sensor technologies to enable embedded gas sensing at high temperature. The team's goal is to develop novel materials with large optical responses and high-temperature stability for integration with optical sensor platforms.
A research group of the NIMS International Center for Materials Nanoarchitectonics (MANA) succeeded in in-situ band-gap tuning which will be a key toward developing high-performance nanoscale devices using ultimately thin graphene oxide membranes.
Nanotechnology researchers have developed a technique for creating nanoparticles that carry two different cancer-killing drugs into the body and deliver those drugs to separate parts of the cancer cell where they will be most effective.
During a recent experiment, a number of gold nanorods were irradiated with xenon atoms. They were a good subject for the experiment because nanowires or rods have a large surface area. The findings were dramatic. The scientists were hoping to generate bubbles. They actually found that they were eroding the nanowires.
Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than 30 percent.
