The Use of Copper Ions and Tannic Acid to Enhance the UV Protection of Cotton Fabrics

Journal of Natural Fibers, 2022
An ultraviolet (UV)-protective cotton fabric has been developed by combining tannic acid and copper ions (TA-Cu) on cotton fabrics. The structure and properties of TA-Cu and cotton fabrics finished with TA-Cu were characterized by Fourier-transform ...

UV Photoelectron Spectroscopy of Aqueous Solutions

Accounts of Chemical Research, 2022
Knowledge of the electronic structure of an aqueous solution is a prerequisite to understanding its chemical and biological reactivity and its response to light. One of the most direct ways of determining electronic structure is to use photoelectron spectroscopy to measure electron binding energies.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Characterization and digital restauration of XIV-XV centuries written parchments by means of non-destructive techniques. Three case studies [PDF]

, 2018
Parchment is the primary writing medium of the majority of documents with cultural importance. Unfortunately, this material suffers of several mechanisms of degradation that affect its chemical-physical structure and the readability of text.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
