Self-folding origami machines powered by chemical reactions

A Cornell-led collaboration harnessed chemical reactions to make microscale origami machines self-fold—freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.

Tweaking Mother Nature's chemistry box

Natural enzymes are very clever molecular machines. They are the catalyst for many of nature's chemical transformations. And the conditions they need to perform their task are rather precisely defined. There is a need to ...

A thin-skinned catalyst for chemical reactions

A chemical nanostructure developed by Boston College researchers behaves much like the pores of the skin, serving as a precise control for a typically stubborn method of catalysis that is the workhorse of industrial chemistry.

Chemists mimic bombardier beetles to safeguard ATMs

(Phys.org) —A team of chemists in Switzerland has developed a new way to protect cash inside of ATM machines from thieves—by automatically setting off a nasty chemical reaction if the machine is molested. The group has ...

Mapping redox switches in cyanobacteria advances use as biofuel

Chemical reactions involving reduction and oxidation, or redox, play a key role in regulating photosynthesis in plants and metabolism in animals and humans, keeping things running on an even keel. Now, in a study reported ...
