Ohno continuous casting (O.C.C.) process has been successfully applied to prevent the nucleation of crystals on the mold wall. It is well known that maintenance of a flat crystal/melt interface is absolutely necessary if one wants to obtain a single cryst...

The achiral hydrocarbon tetraphenylethylene crystallizes in enantiomorphous forms (chiral space group: P21) to afford right- and left-handed hemihedral crystals, which can be recognized by solid-state circular dichroism spectroscopic analysis. Chiral organic crystals of tetraphenylethylene mediated enantioselective addition of ...

A combined University / Industry team has developed a prototype system for handling protein crystals aboard the space station. This system uses a miniature direct drive robot, CCD television cameras, and a client-server computing system using internet protocols to support the capture of protein crystals from aqueous growth solutions. The system was ...

The synthesis of quinoline-derived helically folded aromatic oligoamides functionalized by various chiral functions at their N-terminus is reported. When a (1S)-(-)-camphanyl moiety was introduced, it was found that helix handedness was completely shifted to right-handed helicity (de > 99%), in both protic and nonprotic solvents. The absolute helical sense and the de values ...

The performance of absolute quartz-crystal barometers is analyzed and discussed. Their ability to measure sub-microbar, atmospheric pressure fluctuations at time scales down to seconds is demonstrated. The first observations of ocean-generated, atmospheri...
