Pressure-induced structural strain in (R)-3-quinuclidinol crystals is analysed over different pressure ranges[under pressure] and com­pared with structural strain on cooling.

The methodology proposed combines the DFT calculations and photoelasticity caused by uniaxial compression of the crystal lattice, with particular emphasis on its anisotropy. It can be considered as part of optical engineering aimed at preliminary assessment of the photoelastic properties of crystal materials, thus assisting in their selection for synthesis and relevant applications.

Several Li⁺/Fe³⁺-doped Pbca orthoenstatite and Pbcn protoenstatite crystals were characterized revealing that varying levels of doping preferentially affect the py­rox­ene topologies.

Electron density distribution in bis(guanidinium) disodium hypodiphosphate heptahydrate, (CH₆N₃)₂Na₂(P₂O₆)·7H₂O, is reported.

A rare complex incommensurate magnetic structure, an amplitude-modulated structure which itself is modulated, was determined in the Ho-based i-MAX phase (Mo_2/3Ho_1/3)₂GaC. It represents a particularly distinctive case of a 2-k magnetic structure with no symmetry relation between the propagation vectors.

The patterns of microbial crystallization are controlled by the chemical composition of biofilms associated with environmental exposure and the activity of microorganisms. The nutrition of microorganisms changes the oxalic acid and extracellular polymer substance content in the products of microbial metabolism, which significantly affects the medium pH promoting either the oxalate or carbonate crystallization.

The online software server SARAh—webRepresentational Analysis is introduced. The new suite of web apps carries out a range of calculations based on representation theory for the modelling of possible magnetic structures, their refinement from neutron scattering data and the analysis of other problems in condensed matter.
