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 photoluminescence study of SiAg [PDF]
Physica B: Condensed Matter, 2001 Abstract Photoluminescence band at 780 meV , previously assigned to silver-related centers in Si on basis of indirect arguments, is investigated in detail. For that purpose specially prepared samples doped with isotopically enriched silver are used.

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.

Nanosecond X-ray photon correlation spectroscopy using pulse time structure of a storage-ring source
IUCrJ, 2021 X-ray photon correlation spectroscopy (XPCS) is a routine technique to study slow dynamics in complex systems at storage-ring sources. Achieving nanosecond time resolution with the conventional XPCS technique is, however, still an experimentally ...

Time‐resolved NMR studies of RNA folding [PDF]
Biopolymers, 2007 AbstractThe application of real‐time NMR experiments to the study of RNA folding, as reviewed in this article, is relatively new. For many RNA folding events, current investigations suggest that the time scales are in the second to minute regime.

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.

Real-time direct and diffraction X-ray imaging of irregular silicon wafer breakage
IUCrJ, 2016 Fracture and breakage of single crystals, particularly of silicon wafers, are multi-scale problems: the crack tip starts propagating on an atomic scale with the breaking of chemical bonds, forms crack fronts through the crystal on the micrometre scale ...

Event-based contact angle measurements inside porous media using time-resolved micro-computed tomography [PDF]
, 2020 Hypothesis: Capillary-dominated multiphase flow in porous materials is strongly affected by the pore walls' wettability. Recent micro-computed tomography (mCT) studies found unexpectedly wide contact angle distributions measured on static fluid ...
