Mechanistic Understanding of Protein–MOF Integration Through Surfactant‐Driven Interfacial Design

Advanced Science, EarlyView.
This study reveals how surfactant‐driven interfacial design governs the assembly and stability of protein@MOF composites. Using lipid‐based nonionic surfactants, we modulate protein–MOF interactions to improve encapsulation efficiency, MOF crystallization, and catalytic performance.

The mechanism of recrystallization of carbon steels

Литьë и металлургия
A nanostructural mechanism for recrystallization of carbon steels has been developed. First, structure‑forming nanocrystals of austenite, ferrite and cementite are formed from elementary nanocrystals of iron and graphite, free iron and carbon atoms.

Solubility Enhancement of Domperidone by Solvent Change In situ Micronization Technique

Advanced Biomedical Research, 2018
Background: Domperidone (DOM), a dopamine receptor antagonist, is used as antiemetic for the treatment of gastroparesis, vomiting, and nausea. The low water solubility of DOM leads to a low dissolution rate and variable bioavailability.

Measuring energy-dependent photoelectron escape in microcrystals

IUCrJ, 2020
With the increasing trend of using microcrystals and intense microbeams at synchrotron X-ray beamlines, radiation damage becomes a more pressing problem.

Dual‐Wavelength Control of Charge Accumulation in Rubrene Microcrystals with Anisotropic Conductivity

Advanced Science, EarlyView.
Rubrene microcrystals, forming two distinct sector types, are investigated using photoemission electron spectroscopy. The two sectors exhibit a built‐in charge landscape, arising from anisotropic conductivities. Upon excitation with UV light, the diamond‐shaped sectors accumulate significant charge, whereas the triangular sectors remain essentially ...

Sample manipulation and data assembly for robust microcrystal synchrotron crystallography

IUCrJ, 2018
With the recent developments in microcrystal handling, synchrotron microdiffraction beamline instrumentation and data analysis, microcrystal crystallography with crystal sizes of less than 10 µm is appealing at synchrotrons. However, challenges remain in

Comparing serial X-ray crystallography and microcrystal electron diffraction (MicroED) as methods for routine structure determination from small macromolecular crystals

IUCrJ, 2020
Innovative new crystallographic methods are facilitating structural studies from ever smaller crystals of biological macromolecules. In particular, serial X-ray crystallography and microcrystal electron diffraction (MicroED) have emerged as useful ...

Spatially Confined Crystallization of Patterned MAPbBr_3−xCl_x Microcrystals

Crystals
Patterned lead-halide perovskite microstructures are promising for integrated optoelectronics, photonics, and polarization-sensitive devices, but the practical growth behavior of compositionally tunable microcrystals under simple static confinement ...

Dose-resolved serial synchrotron and XFEL structures of radiation-sensitive metalloproteins

IUCrJ, 2019
An approach is demonstrated to obtain, in a sample- and time-efficient manner, multiple dose-resolved crystal structures from room-temperature protein microcrystals using identical fixed-target supports at both synchrotrons and X-ray free-electron lasers
