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

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
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 ...

Lipidic cubic phase injector facilitates membrane protein serial femtosecond crystallography [PDF]

Nature Communications, 2014
Lipidic cubic phase (LCP) crystallization has proven successful for high-resolution structure determination of challenging membrane proteins. Here we present a technique for extruding gel-like LCP with embedded membrane protein microcrystals, providing a continuously renewed source of material for serial femtosecond crystallography.

Metal‐Coordination Specificity and Structural Dynamics of C. elegans Metallothionein I: Insights From 3D Modeling and MD Simulations

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 2, Page 620-632, February 2026.
ABSTRACT Metallothioneins (MTLs) are small, cysteine‐rich proteins known for their ability to bind metal ions and exhibit flexible, disordered structures. The structural and functional characteristics of metallothionein I (MTL‐1) from Caenorhabditis elegans were investigated, focusing on its behavior in both metal free (MTL‐1 Apo) and metal‐bond states

SPIND: a reference-based auto-indexing algorithm for sparse serial crystallography data

IUCrJ, 2019
SPIND (sparse-pattern indexing) is an auto-indexing algorithm for sparse snapshot diffraction patterns (`stills') that requires the positions of only five Bragg peaks in a single pattern, when provided with unit-cell parameters.

Associating protein residues in the literature with structural data

Acta Crystallographica Section D, Volume 82, Issue 2, Page 113-125, February 2026.
A software tool is introduced for associating text mentions of protein residues with their respective residues in a protein structure, with display in a molecular viewer.Protein structures are crucial in understanding the function, mechanism and disease‐causing variants of proteins within any living cell.

Light Up a Nanocluster

Aggregate, Volume 7, Issue 1, January 2026.
Atomically precise metal nanoclusters are ultrasmall aggregates of metal atoms with finely tunable structures. They exhibit broad PL across visible to NIR wavelengths by tuning size, structure, and composition. The review addresses fundamental emission mechanisms and structure–property correlations, evaluating enhancement strategies (ligand ...

Femtosecond x-ray diffraction from an aerosolized beam of protein nanocrystals [PDF]

, 2017
We demonstrate near-atomic-resolution Bragg diffraction from aerosolized single granulovirus crystals using an x-ray free-electron laser. The form of the aerosol injector is nearly identical to conventional liquid-microjet nozzles, but the x-ray ...
