Making carbon–carbon bonds is hard. Linking racemic mixtures of two alkyls while simultaneously controlling the stereochemistry of both ends of the product is nigh on impossible. Now Gregory Fu, ...

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 ...

WE are greatly interested to read of the success obtained by Prof. Karagunis and G. Coumoulos in effecting a partial resolution of a complex chromium salt by the use of active quartz. Following up the ...
