Interfacial Donor–Acceptor Nanofibril Composites for Selective Alkane Vapor Detection
Alkane fuel is a key ingredient in combustible material such as gasoline, airplane fuel, oil – even a homemade bomb. Yet it’s difficult to detect and there are no portable scanners available that can sniff out the odorless and colorless vapor. But University of Utah engineers have developed a new type of fiber composite for a handheld scanner that can detect small traces of alkane fuel vapor, a valuable advancement that could be an early-warning signal for leaks in an oil pipeline, an airliner, or for locating a terrorist’s explosive. It involves two nanofibers transferring electrons from one to the other.
“These are 2 materials that interact well together by having electrons transferring from one to an...
