Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

Advanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.

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.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Experimental strategies for the investigation of low temperature properties in granitic and pegmatitic melts [PDF]

, 1993
The physical behavior of silicate melts during the final stages of intrusion in the earth's crust are poorly understood. In particular, the low temperature limit of igneous petrogenesis is poorly constrained.
