四年前,理论物理学家提出,晶体结构的手性可以用一个单一数值 G0来量化。该数值由一个极矢量和一个轴矢量的内积给出:极矢量是电偶极矩,轴矢量则是电环偶极矩,它描述了电子自旋与轨道轴之间的几何关系,只在少数具有复杂轨道排布的晶体中出现。
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 asymmetry in nature, where an object or molecule cannot be superimposed onto its mirror image. In the context of nanotechnology, chirality refers to the ...
In the past several decades, significant progress has been made in controlling molecular chirality, as evidenced by the several Nobel Prizes in chemistry awarded in this area, particularly for ...
In nature, molecules often show a strong preference for partnering with other molecules that share the same chirality or handedness. A behavior that is quite evident in the phenomenon known as ...
(a) Schematics of nonreciprocal transports by fluctuating Cooper pairs. (b) Observed amplitude of nonreciprocity in the chiral organic superconductor in comparison with polar inorganic superconductors ...
Researchers demonstrate reversible switching of supramolecular chirality using light, enabling new design strategies for optical and electronic materials. (Nanowerk News) Self-assembly or ...
A team of chemists has made significant strides in the field of mechanically interlocked molecules (MIMs). Their work showcases the development of a compact catenane with tuneable mechanical chirality ...
A project led by Spain's ICFO photonics research center has developed an ultrafast technique for the imaging of molecular chirality with extremely high temporal resolution. The dynamics of chiral ...
In our high school chemistry classes we all learn about chirality, the property of organic molecules in which two chemically identical molecules can have different structures that are mirror images of ...
