Using photocaging for fast time-resolved structural biology studies
Acta Crystallographica Section D: Structural Biology, 2021 This review summarizes the best characterized and most relevant photocaging groups for time-resolved structural biology described in the literature to date. It provides a walkthrough of the essential factors to consider in designing a suitable photocaged

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL
IUCrJ, 2021 Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Time-resolved X-ray Scattering Studies of Proteins
Current Opinion in Structural Biology, 2021 Time-resolved small- and wide-angle X-ray scattering (SAXS/WAXS) studies of proteins in solution based on the pump-probe approach unveil structural information from intermediates over a broad range of length and time scales.

Time-Resolved Study of Thymine Dimer Formation [PDF]
Journal of the American Chemical Society, 2005 The formation of thymine dimers in the single-stranded oligonucleotide, (dT)20, is studied at room temperature by laser flash photolysis using 266 nm excitation. It is shown that the (6-4) adduct is formed within 4 ms via a reactive intermediate. The formation of cyclobutane dimers is faster than 200 ns.

Time-resolved studies of metalloproteins using X-ray free electron laser radiation at SACLA.
Biochimica et Biophysica Acta - General Subjects, 2020 BACKGROUND The invention of the X-ray free-electron laser (XFEL) has provided unprecedented new opportunities for structural biology. The advantage of XFEL is an intense pulse of X-rays and a very short pulse duration (

Micro-structured polymer fixed targets for serial crystallography at synchrotrons and XFELs
IUCrJ, 2023 Fixed targets are a popular form of sample-delivery system used in serial crystallography at synchrotron and X-ray free-electron laser sources. They offer a wide range of sample-preparation options and are generally easy to use.

Time-resolved studies of the spin-transfer reversal mechanism in perpendicularly magnetized magnetic tunnel junctions [PDF]
, 2016 Miniaturized magnetic tunnel junctions enable single-shot time-resolved studies of magnetization reversal driven by spin currents that can test basic physical models, particularly as recent technological advances enable the study of sub-100 nm diameter ...

Time-resolved photoluminescence studies of perovskite chalcogenides
Faraday Discussions, 2022 The rates of excited-state decay through recombination processes determine the usefulness of a semiconductor for ambipolar devices. We find that recombination rates in chalcogenide perovskites are promising for continued progress towards solar cells.
