Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

Advanced Healthcare Materials, Volume 15, Issue 34, 11 September 2026.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)

Two Dimensional MOF Encapsulating Magnetic Char Beads for Removal of Microplastic and Dissolved Arsenic From Aqueous System

Advanced Sustainable Systems, Volume 10, Issue 9, September 2026.
A versatile MCK6@MOF hybrid, comprising KOH‐activated magnetic carbon beads positioned between stacked 2D metal–organic framework sheets, captures polystyrene microplastics and dissolved arsenic from water. Under ambient conditions, the hybrid achieves ∼100% removal within 15 min through electrostatic attraction, π–π interactions, hydrogen bonding and ...

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 5, Page 2096-2105, September/October 2026.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4829-4840, September 2026.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.
