The main interaction between pyridine and zeolites leads to form a hydrogen bond between the N atom of pyridine and OH groups of zeolites. The present work reports a theoretical study about the structural, vibrational and topological properties of the charge distribution of the molecular complexes between pyridine and a series of acids sites of zeolites. The calculated structural parameters...

Radical-mediated thiodesulfonylation of the vinyl and (α-fluoro)vinyl sulfones, derived from aldehydes and ketones, with aryl thiols in organic or aqueous medium provided access to vinyl and (α-fluoro)vinyl sulfides. The vinyl sulfides were formed predominantly with E stereochemistry independent of the stereochemistry of the starting vinyl sulfones.

the aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. a series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of ts viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. the microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...

Mesoporous α-Fe2O3 thin films with large area homogeneity demonstrate tremendous potential in multiple applications. In the present work, synthesis of morphology-controlled is realized polystyrene-block-poly(4-vinyl pyridine) (PS-b-P4VP) diblock copolymer assisted sol-gel chemistry. The solvent category (DMF and 1,4-dioxane) polymer-to-FeCl3 ratio used for solution preparation are systematicall...

We study the slowing down of polymer dynamics in canonical nanocomposites made strongly interacting mixtures poly-2-vinyl pyridine and silica nanoparticles (radius R = 7 ± 2 nm) by means low-field NMR relaxometry. demonstrate that this technique enables accurate quantification fraction immobilized (irreversibly adsorbed) on to filler surface, a manner complements data from broadband dielectric ...
