Cosmic crystallography: the hyperbolic isometries [PDF]
arXiv, 2000 All orientation preserving isometries of the hyperbolic three-space are studied, and the probability density of conjugate pair separations for each isometry is presented. The study is relevant for the cosmic crystallography, and is the theoretical counterpart of the mean histograms arising from computer simulations of the isometries.

Crystallography and Geopolitics [PDF]
Science, 2014 Developed and developing nations recognize that innovation is key to their economies. Connecting this with the discipline of crystallography may not seem immediately apparent, but during the past century, understanding the structure of matter has transformed industries and created new frontiers, from the design of new medicines and materials to ...

MolProbity: all-atom structure validation for macromolecular crystallography
Acta Crystallographica Section D: Biological Crystallography, 2009 MolProbity structure validation will diagnose most local errors in macromolecular crystal structures and help to guide their correction.

Advanced Materials Interfaces, EarlyView.This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...

Advanced Materials Interfaces, EarlyView.2D Ruddlesden‐Popper phase perovskite (RPP) films for applications in photovoltaics are shown to exhibit structural heterogeneities at both microscopic and mesoscopic scales that can affect cross‐film charge carrier transport. The mechanisms of RPP film formation and the possible means to control film structure to optimize 2D perovskite solar cell ...

Topics on mathematical crystallography [PDF]
arXiv, 2014 In July 2012 the General Assembly of the United Nations resolved that 2014 should be the International Year of Crystallography, 100 years since the award of the Nobel Prize for the discovery of X-ray diffraction by crystals. On this special occasion, we address several topics in mathematical crystallography.

The no-defect conjecture in cosmic crystallography
, 1996 The topology of space is usually assumed simply connected, but could be multi-connected. We review in the latter case the possibility that topological defects arising at high energy phase transitions might still be present and find that either they are ...
