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.

Fuel quality combustion analysis [PDF]

open access: yes
A high pressure research combustor operating over a wide range of burner inlet conditions was used to determine the effects of fuel molecular structure on soot formation. Six test fuels with equal hydrogen content (12.8%) were blended to stress different

Balancing Sustainability and Performance: Bio‐Based Epoxy Systems for Durable Flax Fiber‐Reinforced Composites

open access: yesPolymer Composites, EarlyView.
Bio‐based epoxy systems enabling sustainable, durable, and high‐performance flax fiber composites. ABSTRACT Three bio‐based epoxy systems—Polar Bear, Green Turtle, and Plankton—featuring bio‐carbon contents of 28% to 70%, were combined with recyclable (Recyclamine R101) and non‐recyclable hardeners to produce flax fiber‐reinforced biocomposites.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.
