Chemistry Of Cooking
A biochemist and cook
explains that cooking is all
about chemistry and knowing
some facts can help chefs
understand why recipes go
wrong. Because cooking is
essentially a series of
chemical reactions, it is

Strange Matter
Materials scientists are
touring the country with a
traveling museum exhibit
about the science of stuff.
They introduce people to the
innovations of their
discipline, everything from
the lightest material ever

Metal Rubber
Polymer chemists have
created a flexible,
indestructible material,
called metal rubber, that
can be heated, frozen,
washed or doused with jet
fuel, and still retain its
electricity-conducting

Sniffing Out Bombs
A tiny sensor that monitors
electrical conductivity
allows scientists to detect
the presence of explosives.
The sensor measures the
conductivity of two
different thin films, one
made of a cobalt compound

Engineers Make Cheaper, Brighter Displays Out Of Organic Materials
Organic Light-Emitting Diodes (OLEDs) are plastic-based materials that are able to emit light. Engineers are beginning to make displays out of OLEDs by spraying the materials on a surface, the way an ... > more -
Food Chemists Use 'Edible Antifreeze' To Make Smoother Ice Cream
Chemists adding a tasteless edible protein called gelatin hydrolysate to ice cream find that it keeps ice crystals small, resulting in a smoother, more pleasing product. The protein inhibits the ... > more -
Chemists Steal Engineering Tricks from Sponges
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even ... > more -
Micro-X-Ray Fluorescence Also Provides Spectroscopic Information
Ordinary invasive fingerprinting techniques, such as dusting, are prone to damaging evidence. Micro-X-ray fluorescence images fingerprints without touching them. By stimulating atoms to emit ... > more -
Materials Chemists Apply Photonic Crystals to Forensics
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new ... > more -
Materials Scientists Create Polymer Coating Against Fogged Glass
When moisture condenses on a cool surface, droplets can form that are the right size to scatter light, fogging up glass. A new polymer coating draws droplets into nanopores and transforms them into a ... > more -
Chemists Use Polymers To Develop Thicker And More Durable Paint
Chemists have added polymers to a new paint that dries faster and requires no second coat or primer. The paint uses long polymer chains to surround pigments, which makes it easier for latex spheres ... > more -
Materials Scientists Copy Beetle Anatomy To Develop New Coatings
Scientists at M.I.T. looking to add new chemical functionalities to spray coatings have turned to the beetle for inspiration. Some beetles that live in very arid climates get their drinking water by ... > more -
A Vacuum Alternative to Pesticides for Microbiology Solution
A physical chemist has developed a new technique for ridding harvested produce of insect pests and microorganisms without using pesticides such as methyl bromide. The technique, called Metabolic ... > more -
Materials Scientists Make Valentine Treats Affordable
New and improved technology has now made growing diamonds cost-competitive with mining them. Diamond-making machines subject a graphite-carbon core and a diamond seed at a pressure of 850,000 PSI for ... > more
