Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

In situ serial crystallography facilitates 96-well plate structural analysis at low symmetry
IUCrJThe advent of serial crystallography has rejuvenated and popularized room-temperature X-ray crystal structure determination. Structures determined at physiological temperature reveal protein flexibility and dynamics. In addition, challenging samples (e.g.

Small, EarlyView.High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

steel research international, EarlyView.The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

Time‐resolved 3D imaging opportunities with XMPI at ForMAX
Journal of Synchrotron Radiation, EarlyView.The first implementation of X‐ray multi‐projection imaging (XMPI) at the ForMAX beamline (MAX IV) enables the acquisition of multiple projections simultaneously without requiring sample rotation. This approach facilitates volumetric studies of fast dynamics at frame rates of 12.5 kHz with micrometre resolution, with the potential of even higher speeds,

Characterizing gas flow from aerosol particle injectors
, 2017 A novel methodology for measuring gas flow from small orifices or nozzles into vacuum is presented. It utilizes a high-intensity femtosecond laser pulse to create a plasma within the gas plume produced by the nozzle, which is imaged by a microscope ...
