Contributions of Philip Coppens to Chemical Crystallography

Contributions of Philip Teitelbaum to affective neuroscience.

As part of a festschrift issue for Philip Teitelbaum, I offer here the thesis that Teitelbaum deserves to be viewed as an important forefather to the contemporary field of affective neuroscience (which studies motivation, emotion and affect in the brain). Teitelbaum's groundbreaking analyses of motivation deficits induced by lateral hypothalamic damage, of roles of food palatability in revealin...

Contributions of Crystallography to Materials Science*

The properties ofmaterials used in various domains of science and engineering are directly correlated to the microstructure. Crystallography is devoted to the investigaton ofmicrostructure of substances and materials by a variety of diffraction and spectroscopic methods. Several examples related to research in the department of materials science at the Technical University of Darmstadt are pres...

Chemical Crystallography

Automated chemical crystallography.

The first fully automated small-molecule robotic X-ray diffractometer is described. After demonstrating the utility of the instrument using multiple samples of ammonium bitartrate, we investigated the conformational chirality of diphenyl dichalcogenide (E(2)Ph(2), where E = S, Se, or Te). Structural and computational studies suggest that the two enantiomers are energetically indistinguishable. ...

Structure validation in chemical crystallography

Automated structure validation was introduced in chemical crystallography about 12 years ago as a tool to assist practitioners with the exponential growth in crystal structure analyses. Validation has since evolved into an easy-to-use checkCIF/PLATON web-based IUCr service. The result of a crystal structure determination has to be supplied as a CIF-formatted computer-readable file. The checking...
