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 ...

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 ...

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 ...

In the beginning, there were chiral molecules. RNA, DNA, proteins, and other biological molecules tend to be present as only either right- or left-handed. However, scientists are not sure how this ...

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 ...

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 ...

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

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 ...
