Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

open access: yesSmall, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.

Conversion‐Type Anodes: Challenges, Mitigation Strategies, and Evaluation Guidelines

open access: yesSmall, EarlyView.
Conversion‐type anodes offer high theoretical capacity but exhibit coupled electrochemical, interfacial, mechanical, and transport limitations that complicate performance interpretation. A practical evaluation framework is presented to distinguish intrinsic reaction chemistry from electrode‐scale effects through complementary diagnostics and ...

Nature‐Inspired Histidine and Guanidine Modification of Magnetic Nanoparticles for Urinary DNA Liquid Biopsy

open access: yesSmall Methods, EarlyView.
Nature‐inspired bi‐functionalized magnetic nanoparticles are engineered for the rapid, non‐invasive extraction of cell‐free DNA from unprocessed urine for liquid biopsy. These cationic particles leverage electrostatic interactions to outperform conventional kits, enhancing the recovery of short DNA fragments while maintaining DNA integrity.

Hydrogen‐Based Reduction of Hematitic Iron Ore in a Fluidized Bed Kinetic Reactor at Elevated Pressures

open access: yessteel research international, EarlyView.
This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

open access: yessteel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Fundamental magnetic properties of Greigite (Fe3S4)

open access: yes, 2009
Over the last twenty years, greigite (Fe3S4), an authigenic magnetic iron sulphide mineral, has been increasingly identified in sulphate-reducing marine and lacustrine sedimentary systems.

Isothermal Reduction Behavior and Microstructural Evolution of Iron Ore Sinter Under Simulated Radial Blast Furnace Gas Atmospheres With Hydrogen Injection

open access: yessteel research international, EarlyView.
Commercial iron ore sinter is reduced isothermally under operation‐derived radial blast furnace gas atmospheres with and without 20 kg H2/tHM injection. Hydrogen improves reduction at 900–1100 °C, whereas at 700 °C the high H2O content limits the wüstite‐to‐iron driving force.
