Rapid Generation of Fusable Cell Beads for Multi‐Scale Human Living Materials Assembly

Small Methods, EarlyView.
Living beads are produced through the combination of metabolic glycoengineering, click chemistry, and superhydrophobic surfaces, to develop a spheroid alternative for bottom‐up tissue engineering and disease modeling. The living beads present a size independent of cell density and a rapid fabrication methodology, providing a platform that can fuse into

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Radical-Mediated Anti-Markovnikov Hydrophosphonation of Olefins [PDF]

, 2011
The radical-mediated addition of triphenylphosphonium tetrafluoroborate to olefins (hydrophosphonation) is reported. Both standard radical initiators and photochemical conditions are effective, up to the gram scale.

Photochemical Synthesis of Polycyclic Phosphonium Salts as Efficient Anticancer and Antibacterial Agents

Aggregate
Phosphorus‐containing functional materials have diverse applications in optoelectronics and bioscience owing to their unique properties. However, polycyclic π‐conjugated phosphonium salts have been rarely explored due to their complex synthesis.

Efficient and recyclable Rh-catalytic system with involvement of phosphine-functionalized phosphonium-based ionic liquids for tandem hydroformylation–acetalization

Green Energy & Environment, 2017
The phosphine-functionalized phosphonium-based ionic liquids (dppm-Q, dppe-Q, dppp-Q and dppb-Q) as the bi-functional ligands enable the efficient one-pot tandem hydroformylation–acetalization.

Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde

Photochemistry and Photobiology, EarlyView.
The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...
