Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

UV-driven trace Cu(II)/peroxymonosulfate for efficient degradation of phosphonate: Mechanism and broad pH adaptability

Chemical Engineering Journal Advances
Organic phosphonates detected frequently in water bodies pose severely environmental risks, and the cleavage of their C-P bonds to converse orthophosphate (PO43-) serves as a prerequisite step for achieving deep phosphorus elimination.

Redox Activity of the Mini-αA-crystallin–Cu(II) Complex and Its Biological Relevance

International Journal of Electrochemical Science, 2015
Cu(II) has been known to be a redox-active metal whose complexes with proteins/peptides have been linked to oxidative stress in many diseases. Oxidative stress and Cu(II) are also known to induce the expression of the small heat shock proteins α ...

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...
