New research describes how the modulation of the geometry of a helical reactor at a macroscopic level enables controlling the sign of chirality of a process at a nanometric scale, an unprecedented ...

Circularly polarized light has properties that make it useful in a growing range of technologies, from next-generation 3D ...

Chirality is a fundamental property of asymmetry in nature, where an object or molecule cannot be superimposed onto its mirror image. In the context of nanotechnology, chirality refers to the ...

Researchers have achieved a significant breakthrough in the synthesis of carbon nanotubes (CNTs) by developing a novel catalyst that allows for precise control over their atomic arrangement, known as ...

Chirality is a fundamental property of many organic molecules and means that chemical compounds can appear in not only one form, but in two mirror-image forms as well. Chemists have now found a way to ...

A conch shell—with its twisting, spiraled insides—is impossible to transform into a mirror image of itself. That's because it expresses chirality, one of the properties of asymmetry where the shell ...

A new, real-time technique to measure the changes in chirality of biomolecules in the deep ultraviolet part of the electromagnetic spectrum could be important for improved drug development and ...

It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be ...

The chirality lies in the geometry Scanning electron microscopy (SEM) image of nickel-based artificial chiral magnets fabricated at EPFL’s Center of MicroNanoTechnology. (Courtesy: Mingran Xu, Dirk ...
