When sunbathers splash into the ocean to cool off, some of their lotions and creams get rinsed into the water. The problem is that titanium dioxide and zinc oxide nanoparticles, which are common ingredients in sunblock, can react with ultraviolet light from the sun and form new compounds, such as hydrogen peroxide, that could be toxic.
A simple and effective way of unravelling the often tangled mass of DNA is to 'thread' the strand into a nano-channel. A new study used simulations to measure the characteristics that this channel should have in order to achieve maximum efficiency.
For the first time, chemists have succeeded in measuring vibrational motion of a single molecule with a femtosecond time resolution. The study reveals how vibration of a single molecule differs from the behaviour of larger molecular groups.
David Erickson, professor of mechanical and aerospace engineering at Cornell University, will receive a $3 million National Science Foundation grant over five years to adapt smart phones for health monitoring.
The topics discussed at the NATO Advanced Research Workshop 'Nanotechnology in the Security Systems' included nanophysics, nanotechnology, nanomaterials, sensors, biosensors security systems, explosive detection.
