Freestanding carbon nanotubes may be thinner than previously thought possible
How to identify chiral superconductivity in new materials
Scientists refine formula for nanotube types
(Phys.org) —Many a great idea springs from talks over a cup of coffee. But it's rare and wonderful when a revelation comes from the cup itself.
Breakthrough harnesses light for controlled chemical reaction
When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants "learned" to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit ...
The hemihelix: Scientists discover a new shape using rubber bands (w/ video)
While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature.
Caps not the culprit in nanotube chirality
(Phys.org) —A single-walled carbon nanotube grows from the round cap down, so it's logical to think the cap's formation determines what follows. But according to researchers at Rice University, that's not ...
Snapshots differentiate molecules from their mirror image
(Phys.org) —Small difference, large effect: Most biological molecules occur in two variants, an original and its mirror image. As a result, they are related to one another like the left hand to the right. ...
New method of producing stereoisomers developed
Researchers develop optically switchable chiral terahertz metamolecules
A multi-institutional team of researchers that included scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) has created the first artificial molecules whose chirality can be rapidly switched ...
Researchers unlock mystery of how 'handedness' arises
The overwhelming majority of proteins and other functional molecules in our bodies display a striking molecular characteristic: They can exist in two distinct forms that are mirror images of each other, like ...
Pure nanotube-type growth edges toward the possible
New research at Rice University could ultimately show scientists the way to make batches of nanotubes of a single type.
Scientists Give a Hand(edness) to the Search for Alien Life
(PhysOrg.com) -- Visiting aliens may be the stuff of legend, but if a scientific team working at the National Institute of Standards and Technology is right, we may be able to find extraterrestrial life even ...
Nanoscopic static electricity generates chiral patterns
In the tiny world of amino acids and proteins and in the helical shape of DNA, a biological phenomenon abounds.
How does a machine smell? Better than it did
Every odor has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are ...
