Ultra-sensitive polymer detects explosive devices

(Phys.org) —A chemical that's often the key ingredient in improvised explosive devices (IEDs) can be quickly and safely detected in trace amounts by a new polymer created by a team of Cornell chemists.

Bovine blood keeps gold nanoparticles stable

(Phys.org) —A protein from cow blood has the remarkable ability to keep gold nanoparticles from clumping in a solution. The discovery could lead to improved biomedical applications and contribute to projects that use nanoparticles ...

Molecular rings mystery solved after 20 years

Although the double benzene molecule tried to reveal its structure in experiments in 1993, chemists at the time were unable to find an explanation for the spectral peaks they saw. Now, 20 years later, Nijmegen theoretical ...

Build­ing mol­e­cules: Serendipity pays off

Serendipity – the act of finding something good or useful while not specifically searching for it – can sometimes pay off. Now Princeton University chemistry researchers report that this non-specific type of searching ...

CO2 could produce valuable chemical cheaply

(Phys.org) —Researchers at Brown and Yale have demonstrated a new "enabling technology" that could use excess carbon dioxide to produce acrylate, a valuable commodity chemical involved in the manufacture of everything from ...

Nano 'beads on a string' could advance battery technology

Tiny beads of silicon, about ten thousand times thinner than a piece of paper, could someday make electric vehicles travel farther on a single charge or extend the life of your laptop's battery, say scientists at the University ...

The bug that lays the golden egg

Among the more peculiar organisms that inhabit our Earth exists a bacterium that turns water-soluble gold into microscopic nuggets of solid gold, scientists said Sunday.

New study strengthens olfactory vibration-sensing theory

(Phys.org)—A new study by a team of chemists in Greece has added credence to a theory that suggests that humans differentiate smells by sensing molecular vibrations, rather than through simple binding to receptors. In their ...
