Chromium Salt: A Review of Salt Formation, Hygroscopic Properties, and Impact on 316 L Corrosion in Hydrochloric Acid

open access: yesMaterials and Corrosion, EarlyView.
This article examines the impact of externally introduced chromium compounds on the localized corrosion of 316 L stainless steel in acidic chloride environments such as hydrochloric acid. While the corrosion resistance of 316 L relies on the formation of a chromium‐rich passive oxide layer, industrial conditions may expose the steel to various chromium

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

open access: yesMacromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

CO2‐Responsive Dual‐Charge‐Switchable Membranes for Protein Foulant Cleaning

open access: yesMacromolecular Rapid Communications, EarlyView.
CO2‐responsive poly(ether sulfone) ultrafiltration membranes with dual‐charge‐switchable surfaces are prepared by incorporating an amphoteric diblock copolymer additive using the nonsolvent‐induced phase separation method. Alternating CO2 and N2 bubbling changes the solution pH around the copolymer isoelectric point and hence reversibly switches the ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

open access: yesPolymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...

Modélisation numérique des matériaux à changement de phase

open access: yesIncertitudes et Fiabilité des Systèmes Multiphysiques
Les systèmes de refroidissement traditionnels n’ont pas la capacité d’assurer un bon transfert d’énergie thermique. Grâce à l’évolution de ces systèmes, il est possible d’améliorer les nouveaux dispositifs.
