Copernican crystallography [PDF]

open access: yesPhysical Review Letters, 1992
Redundancies are pointed out in the widely used extension of the crystallographic concept of Bravais class to quasiperiodic materials. Such pitfalls can be avoided by abandoning the obsolete paradigm that bases ordinary crystallography on microscopic periodicity.

Crystallography in the 21st century [PDF]

open access: yesIUCrJ, 2015
The field of crystallography, which has had a major impact on the sciences in the last 100 years, is continuing to expand scientific horizons as technical and conceptual boundaries are overcome. Structure-function-dynamics will become an integrated theme for many studies as will obtaining structures without the 'benevolent tyranny' of crystals.

Abstract OR-2: The Formation of Dps-DNA Complexes under Different Conditions According to Cryo-EM and SAXS [PDF]

open access: yesInternational Journal of Biomedicine, 2021
Background: The effect of Dps-DNA co-crystals formation, which occurs in stressed Escherichia coli cells exposed to extreme conditions, is well described in the literature.

The crystallography of Pluto [PDF]

open access: yesIUCrJ, 2020
Maynard-Casely and co-workers [IUCrJ (2020). 7, 844-851.] investigate two of Pluto's most abundant minerals with neutron diffraction. The new results will be key to understanding the geology of our distant neighbour and represent a significant advance in the emerging field of small-molecule geology.

Double-sided liquid crystal metasurfaces for electrically and mechanically controlled broadband visible anomalous refraction

open access: yesNanophotonics, 2022
Liquid crystals self-assemble on nanopatterned alignment layers into purely soft matter metasurfaces sensitive to external stimuli and imparting tailored spatial modulations to transmitted light wavefronts.
