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)

Unraveling the nature of carrier mediated ferromagnetism in diluted magnetic semiconductors [PDF]

open access: yes, 2015
After more than a decade of intensive research in the field of diluted magnetic semiconductors (DMS), the nature and origin of ferromagnetism, especially in III-V compounds is still controversial.

Design and Statistical Optimization of PLA Organoclay‐Based Dispersions for Recyclable Packaging Paper

open access: yesPolymer Engineering &Science, EarlyView.
Through experimental design, polylactic acid (PLA)—organoclay dispersions were optimized to produce biobased coatings that have a high barrier potential while maintaining repulpability, promoting sustainable packaging solutions. ABSTRACT Performance and recyclability of paper coatings depend on precise control of polymer, surfactant, filler ...

Eco-friendly approach and potential biodegradable polymer matrix for WPC composite materials in outdoor application [PDF]

open access: yes, 2019
Blends based on high density polyethylene (HDPE) and poly(lactic) acid (PLA) with different ratios of both polymers were produced: a blend with equal amounts of HDPE and PLA, hence 50 wt.% each, proved to be a useful compromise, allowing a high amount of

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 ...
