Protein crystallization and structure determination at room temperature in the CrystalChip

FEBS Open Bio
The production of high‐quality crystals is a key step in crystallography in general, but control of crystallization conditions is even more crucial in serial crystallography, which requires sets of crystals homogeneous in size and diffraction properties.

Post-refinement method for snapshot serial crystallography [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2014
A post-refinement procedure has been devised for ‘snapshot’ diffraction data consisting entirely of partially recorded reflections, each diffraction pattern from a crystal in an orientation unrelated to the others. Initial estimates of the diffraction geometry are used to calculate initial partialities, which are then used to scale the entire dataset ...

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

Advanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

Crystal structure via fluctuation scattering

IUCrJ
Crystallography is a quintessential method for determining the atomic structure of crystals. The most common implementation of crystallography uses single crystals that must be of sufficient size, typically tens of micrometres or larger, depending on the

Heptazine‐Assisted Multi‐Resonance TADF Emitters With Fast Reverse Intersystem Crossing for Efficient Solution‐Processed OLEDs

Advanced Materials, EarlyView.
Heptazine‐assisted MR‐TADF emitters enable narrowband yellow emission with high efficiency at high luminance in solution‐processed OLEDs. In doped films, HAP‐3CzBN achieves a record‐fast kRISC of 1.19 × 106 s−1. The optimized HAP‐3CzBN devices deliver 15.5% EQEmax with negligible roll‐off at 1000 cd m−2, 11.2% at 10,000 cd m−2, and a benchmark 20.3 ...

Droplet streams for serial crystallography of proteins

Experiments in Fluids, 2007
Serial diffraction of proteins requires an injection method to deliver protein molecules - preferably uncharged, fully hydrated, spatially oriented, and with high flux - into the crossed beams of an alignment laser and a focused probe beam of electrons or X-rays of typically only a few tens of microns diameter.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Phase Engineering of Nanogold: Non‐Close Packed Square Planes in A′B′ Stacking with a 0.5 Å Channel

Advanced Materials, EarlyView.
Gold is well known to adopt the face‐centered‐cubic (fcc) structure. This work presents an unusual non‐close‐packed phase attained in a 40‐atom gold nanocluster, which is in contrast with the close‐packed fcc quasi‐isomer. The non‐compact structure exhibits exclusive square planes in a layer‐by‐layer stacking, hence, possessing a unique 0.5 Å channel ...
