Polymeric links in ancient resin perplex researchers

ANALYTICAL CHEMISTRY

Amber, a relatively simple resin secreted by trees, is among nature’s sturdiest and perhaps most elegant compounds. It is tough enough to withstand millions of years’ worth of environmental abuse, yet it remains capable of capturing light in a gem-like fashion suitable for jewelry.

Ordering of magnetic properties run hot and cold

MATERIALS SCIENCE

Given how much information we regularly store in magnetic form on everything from computer hard disks to credit card strips, researchers are increasingly interested in the stability of magnetic properties in materials. Mary Anne White, a chemist at Dalhousie University...

Photonic chips the last frontier for fibre optics

PHOTONIC CHEMISTRY

As the hardware in communications systems has progressed from copper wires to fibre optic cables, the acceleration of data transfer speed has been profound. No one with access to fibre would ever want to go back to copper connections, but there is still one place we are stuck with them...

Finding laboratory chemicals through the classified ads

EDUCATION

In laboratories around the world, researchers regularly pay top dollar for specialized materials to conduct their work. Afterward, any leftovers usually go into storage, where all too often they remain unused and forgotten. In cases where chemical agents eventually become toxic or volatile, such obscurity can pose physical hazards. But Anna Klinkova sees a more...

Nanotech pares platinum to cut catalysis costs

ANALYTICAL CHEMISTRY

Automobile manufacturers have well-established technology for adding an oxygen molecule to the toxic carbon monoxide from vehicles’ tailpipes, so that the output instead consists of CO2. Unfortunately, this active catalytic oxidation does not come chea...
