Chirality as a Feature of the Crystal Structure of Lanthanide Ion Complexes—Some Simple Examples
Crystals, 2023 Single-crystal X-ray structure determinations are reported for four lanthanide complexes, [Dy(bipy)2Cl2(OH2)2]Cl.H2O (bipy = 2,2′-bipyridine), 1; [La2(phen)2(O2CCH3)4(NO3)2] (phen = 1,10-phenanthroline), 2; [Lu(terpy)(O2CCH3)3].NaNO3 (terpy = 2,2′;6′,2 ...

Chiral extensions of chiral polytopes
Discrete Mathematics, 2014 Given a chiral d-polytope K with regular facets, we describe a construction for a chiral (d + 1)-polytope P with facets isomorphic to K. Furthermore, P is finite whenever K is finite. We provide explicit examples of chiral 4-polytopes constructed in this way from chiral toroidal maps.

Chiral Nanomaterials and Chiral Light [PDF]
Optics and Photonics News, 2016 Advances in nanofabrication are expanding opportunities to exploit and customize the “handedness” of materials-and of light itself.

Application of Natural and Modified Biomacromolecules in Miniaturised Separative Analytical Techniques [PDF]
In pharmaceutical R & D, drug stereochemistry, and consequently the rotation of enantiomers, is very important. Because they act as chiral selectors in vivo, biomacromolecules have been extensively used as chiral selectors for the liquid chromatographic (

Chiral Aspects of Local Anesthetics
Molecules, 2020 Thanks to the progress made in chemical technology (particularly in the methodologies of stereoselective syntheses and analyses) along with regulatory measures, the number of new chiral drugs registered in the form of pure enantiomers has increased over ...

Lattice Quantum ChromoDynamics with approximately chiral fermions [PDF]
, 2008 In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020 How can we tell whether an image has been mirrored? While we understand the geometry of mirror reflections very well, less has been said about how it affects distributions of imagery at scale, despite widespread use for data augmentation in computer vision. In this paper, we investigate how the statistics of visual data are changed by reflection.

Molecules, 2011 Methods for the asymmetric transfer hydrogenation (ATH) of ketones and imines are still being intensively studied and developed. Of foremost interest is the use of Noyori’s [RuCl(η6-arene)(N-TsDPEN)] complexes in the presence of a hydrogen donor (i-PrOH,
