Figure 1. Schematic diagram of the racemic metasurface. (a) Arbitrary polarization-wavefront conversion. (b) Racemic "super-units". Chirality is one of the fundamental phenomena widely present in ...
SINCE the introduction of Tswett's technique of chromatographic adsorption, this process has been applied successfully to the separation of many isomeric or closely related substances, including the ...
It is well established that an enantiomerically pure compound exhibiting advantageous properties not present in its isomer or its corresponding racemic mixture, can be patented even if its ...
