Scientists in France and Scotland identify new encapsulation agents for delivery of nitric oxide, a potent antibacterial agent and vasodilator

06-Jan-2015

A group of scientists led by researchers at the Université de Versailles' Institut Lavoisier in France has worked out how to stably gift-wrap a chemical gas known as nitric oxide within metal-organic frameworks. Such an encapsulated chemical may allow doctors to administer nitric oxide in a more ...

Silicon-based electronics has certain limits, in the physical sense of the word: this type of circuit can never become "nano" because of the physical laws governing the flow of electrons. This imposes a halt to the process of miniaturization of electronic devices. One of the possible solutions is ...

University of British Columbia researchers have developed a technique that brings scientists a big step closer to unlocking the secrets of the most abundant form of matter in the universe. A plasma – or ionized gas – can be as commonplace as in fluorescent light bulbs, or exotic in the extreme, ...
