The role of iron in neurodegenerative disorders : insights and opportunities with synchrotron light [PDF]
, 2014 There is evidence for iron dysregulation in many forms of disease, including a broad spectrum of neurodegenerative disorders. In order to advance our understanding of the pathophysiological role of iron, it is helpful to be able to determine in detail ...

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites
Advanced Materials Technologies, EarlyView.Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

2-[(E)-2-(4-Ethoxyphenyl)ethenyl]-1-methylquinolinium 4-fluorobenzenesulfonate
Acta Crystallographica Section E, 2014 In the structure of the title salt, C20H20NO+·C6H4FO3S−, the 4-(ethoxyphenyl)ethenyl unit is disordered over two positions with a refined site-occupancy ratio of 0.610 (6):0.390 (6). The cation is nearly planar, the dihedral angle between the quinolinium

Advanced Science, EarlyView.Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.

X-ray crystallography determines the atomic and molecular structures of crystalline solids by analyzing the diffraction patterns of X-rays interacting with crystal lattices. This method gives three-dimensional electron density maps that reveal atomic positions, chemical bonds, and crystallographic features, making it indispensable across chemistry ...

1-(2,4-Dinitrophenyl)-2-[(E)-(3,4,5-trimethoxybenzylidene)]hydrazine
Acta Crystallographica Section E, 2014 Molecules of the title compound, C16H16N4O7, are not planar with a dihedral angle of 5.50 (11)° between the substituted benzene rings. The two meta-methoxy groups of the 3,4,5-trimethoxybenzene moiety lie in the plane of the attached ring [Cmethyl–O–C–C ...

Insights into the catalytic mechanisms of a 3-ketosteroid Δ1-dehydrogenase and a β-xylosidase obtained from 3D structures [PDF]
, 2016 Seeing is understanding. In many instances, seeing is the best way to understand natural phenomena. X-ray crystallography is among the most powerful methods to visualize 3D structures of proteins and nucleic acids at the atomic level.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
