Security forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A revolutionary new electronic chip with nano-sized chemical sensors is about to make their job much easier.
Studies on fluid flow at the molecular level have uncovered important data about fluid's unique behavior, and has led to the development of new technologies that can potentially solve some of the world's most pressing issues.
The process uses a technique called high-resolution electron microscopy to monitor changes in the catalyst structure during the catalytic process. Unlike conventional electron microscopy, which has considerable pressure and temperature limitations, this new technique allows scientists to view these reactions under real-life conditions.
The establishment of the University of the Western Cape's Centre for Green Nanotechnology was made a reality through a positive partnership between the University of Missouri (UM) ?and UWC that has spanned approximately 30 years.
DNA has the nasty habit of getting tangled and forming knots. Scientists study these knots to understand their function and learn how to disentangle them. Researchers have now devised and tested a method based on the application of electric fields and optical tweezers.
Researchers have created a vaccine for dust-mite allergies. In lab tests and animal trials, the nano-sized vaccine package was readily absorbed by immune cells and dramatically lowered allergic responses.
Polarization charges in ferroelectric materials are screened by equal amounts of surface charges with opposite polarity under ambient conditions. Researchers have shown that scraping, collecting, and quantifying surface screen charges reveals the underlying polarization domain structure at high speed, a technique dubbed charge gradient microscopy (CGM).
Scientists have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers.
More than 80 percent of all drug candidates in the pharma R+D suffer from poor solubility and are therefore rejected early in the drug discovery process. Now Uppsala University researchers show that the new material Upsalite, has great potential for development of new formulations of these rejected drugs.
The models simulate or mimic complex biological processes, such as evolution, self-replication and immune system behaviors, and the formation of prions, protein particles that may cause brain diseases. The models can be used to help scientists develop artificial self-assembling systems in laboratories and will make valuable contributions to the theoretical understanding of biological systems.
