Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Seed layer formation by deposition of micro‐crystallites on a revolving substrate. Part II: application to some nonlinear effects

open access: yesActa Crystallographica Section B, EarlyView.
A method of averaging the material coefficients of crystallites deposited at an angle onto a revolving substrate isapplied to effective nonlinear dielectric, piezoelectric and elastic constants, as well as linear pyroelectric coefficients, for triclinic crystals.The matrix method of averaging material coefficients of crystallites deposited at an angle ...

Topological Determinism of Prime Quadruplets: Isomorphism, Modular Invariance (Part 1) and Emergence of a Lower Bound (Part 2) via Arithmetic Index Theory (AIT)

open access: yes
Part 1: The asymptotic study of prime quadruplets with topologies (p, p + 2, p + 6, p + 8) and (p, p +4, p + 6, p + 10) has historically been limited by probabilistic and heuristic approaches. This article demonstrates that the Arithmetic Index Theory (AIT) transmutes this complex four-variable problem into a strictly deterministic single ...

Separating the effects of temperature and absorbed X‐ray dose on unit‐cell volume

open access: yesActa Crystallographica Section D, EarlyView.
The nature of the expansion of the crystal unit‐cell volume with absorbed dose and with temperature was examined for three different proteins.The behaviour of the unit‐cell volume of crystals of the iron‐storage molecule ferritin, both in the apo and the holo form, and of influenza A virus subtype N9 neuraminidase at 100 K and over a controlled cryo ...

A short history of Auto‐Rickshaw

open access: yesActa Crystallographica Section D, EarlyView.
Auto‐Rickshaw is an example of practical, decision‐driven automated macromolecular structure determination from crystallographic diffraction data. This review traces its development at the EMBL Hamburg/DESY beamline environment, where rapid validation of diffraction experiments was essential, through its expansion into a general platform for automated ...
