Improving experimental phases for strong reflections prior to density modification.
Experimental phasing of diffraction data from macromolecular crystals involves deriving phase probability distributions. These distributions are often bimodal, making their weighted average, the centroid phase, improbable, so...

The potential of flax shives as reinforcements for injection moulded polypropylene composites
Flax shives (FS) represent approximately 50 % in weight of dry flax stems, making it the main by-product of the flax scutching industry. Being an available and low-added value lignocellulosic resource, flax shives are an...
X-ray diffraction reveals the intrinsic difference in the physical properties of membrane and soluble proteins.
Xavier Robert, Josiane Kassis-Sahyoun, Nicoletta Ceres, Juliette Martin, Michael R Sawaya, Randy J Read, Patrice Gouet, Pierre Falson, Vincent Chaptal
Apr 20, 2018
Membrane proteins are distinguished from soluble proteins by their insertion into biological membranes. This insertion is achieved via a noticeable arrangement of hydrophobic amino acids that are exposed at the surface of the...
Instrument-model refinement in normalized reciprocal-vector space for X-ray Laue diffraction
Radosław Kamiński, Dariusz Szarejko, Martin N. Pedersen, Lauren E. Hatcher, Piotr Łaski, Paul R. Raithby, Michael Wulff, Katarzyna N. Jarzembska
Oct 01, 2020
A simple yet efficient instrument-model refinement method for X-ray diffraction data is presented and discussed. The method is based on least-squares minimization of differences between respective normalized (i.e. unit...
The Impact of Phase Retention on the Structural and Optoelectronic Properties of Metal Halide Perovskites.
Anna Osherov, Eline M Hutter, Krzysztof Galkowski, Roberto Brenes, Duncan K Maude, Robin J Nicholas, Paulina Plochocka, Vladimir Bulović, Tom J Savenije, Samuel D Stranks
Aug 16, 2017
The extent to which the soft structural properties of metal halide perovskites affect their optoelectronic properties is unclear. X-ray diffraction and micro-photoluminescence measurements are used to show that there is a...

Stages, scaffolds and strings in the spatial organisation of non-homologous end joining
Shikang Liang, Amanda K Chaplin, Antonia Kefala Stavridi, Robert Appleby, Ales Hnizda, Tom L Blundell
Jan 20, 2021
Non-homologous end joining (NHEJ) is the preferred pathway for the repair of DNA double-strand breaks in humans. Here we describe three structural aspects of the repair pathway: stages, scaffolds and strings. We discuss the...
