Application:	Cyclic siloxanes conjugated with fluorescent aromatic compounds as fluoride sensors: This study explores the use of cyclic siloxanes conjugated with aromatic compounds for sensing applications, offering a pathway for academic chemists interested in sensor technology and fluorescence studies (N Prigyai et al., 2020 ). Synthesis, film morphology and performance of novel crosslinked polysiloxane with end-capped epoxy groups on cotton substrates: This article examines the chemical modification of cotton substrates using polysiloxane derivatives, which can be crucial for developing advanced textile coatings (L Hao et al., 2014 ). Stabilizing Li-rich layered oxide cathode interface by using silicon-based electrolyte additive: This research investigates the use of a silicon-based additive derived from 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane to enhance the stability of lithium-rich cathodes, important for chemists working with energy storage technologies (T Huang et al., 2024 ).
General description:	In the presence of a Pd catalyst, this reagent cross-couples with aryl bromides to give styrene derivatives.
