Sustainable Upcycling of Office Waste Paper Into Cobalt/Carbon Aerogels for Highly Efficient Microwave Absorption

open access: yesElectron, EarlyView.
Co/C aerogels (Co/CAs) are successfully fabricated with office waste paper (OWP) as the raw material by loading ZIF‐67 crystals. The optimal sample exhibited an effective absorption bandwidth of 5.6 GHz, which outperforms many biomass‐derived microwave absorbing materials.

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Microscale Assemblies of Magnetic Nanoparticles Produced by Dip‐Coating and Lift‐Off With Dissolvable Templates

open access: yesNano Select, EarlyView.
Microscale assemblies of magnetic nanoparticles (MNPs) were created using a combination of dip‐coating with ferrofluids and lift‐off with dissolvable photoresist templates. This technique produced large area arrays of geometrically precise MNP superstructures.

Mesoporous Hollow Carbon Spheres/Nanofibers Anchored With Conductive Bimetallic for Efficient Microwave Absorption

open access: yesRare Metals, EarlyView.
ABSTRACT To break electromagnetic wave absorption (EMA) tech's single‐attenuation bottleneck, enhancing multi‐wave absorption synergy in composites is key for microstructure design. This study uses mesoporous hollow carbon spheres to make metal nanospheres with cobalt, iron, and nickel nanoparticles, then encapsulates them via electrospinning into a ...
