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.
How to identify chiral superconductivity in new materials
Physicists find evidence of new state of matter in a simple oxide
Symmetry is a fundamental concept in physics. Our ‘standard model’ of particle physics, for example, predicts that matter and anti-matter should have been created in equal amounts at the big bang, yet ...
Researchers figure out how to 'grow' carbon nanotubes with specific atomic structures
Move over, silicon. In a breakthrough in the quest for the next generation of computers and materials, researchers at USC have solved a longstanding challenge with carbon nanotubes: how to actually build them ...
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 ...
Freestanding carbon nanotubes may be thinner than previously thought possible
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 ...
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 ...
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 ...
Scientists develop the most advanced computer model to-date of the scattering of polarized light from chiral molecules
(PhysOrg.com) -- An international research team has described the first calculations of Raman optical activity (ROA) spectra using coupled-cluster theory one of the most reliable quantum chemical methods ...
New class of monofluoro acylboronates that is stable in air and water
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.
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.
