The efficiency of sulfur vulcanization reaction in rubber industry is generally improved thanks to the combined use accelerators (as sulphenamides), activators (inorganic oxides), and co-activators (fatty acids). interaction among these species responsible for formation intermediate metal complexes, which are able increase reactivity towards polymer promote chemical cross-links between chains. high number reactions that involved contemporarily process hinders complete understanding its...
Silica-styrene butadiene rubber (SBR) nanocomposites were prepared by using shape-controlled spherical and rod-like silica nanoparticles (NPs) with different aspect ratios (AR = 1-5), obtained a sol-gel route assisted structure directing agent. The used as models to study the influence of particle shape on formation nanoscale immobilized at silica-rubber interface its effect dynamic-mechanical behavior. TEM AFM tapping mode analyses demonstrated that particles are surrounded layer surface....
This article describes the synthesis, characterization, and application of new UV-absorbing microcapsules encapsulating a UV-responsive photochromic dye for in damage-sensing field. Microcapsules filled with spiropyran, dissolved sunflower oil as core material, were synthesized by reacting TDI-based polyisocyanate prepolymer benzophenone-based amine to obtain robust polyurea shells. The newly UV-screening embedded into photoresist realize mechanoresponsive polymer. After scratching coating,...
The present study reports on a simple preparation strategy of hybrid catalyst, TiO2/HKUST-1, containing TiO2 anatase nanoparticles (NPs) with tailored morphology and photocatalytic activity coupled porous metal-organic framework (MOF), namely HKUST-1, as an advanced material for the CO2 reduction.

We comprehensively explored the photocatalytic properties, in H2 production by methanol photosteam reforming, of anatase nanocrystals with nearly rectangular (RC), rhombic (R), and nanobar (NB) shapes having exposed {001}, {101}, {010} surfaces. The aim was to relate reactivity both type crystal facets photogenerated defects. electron spin resonance (ESR) spectra reveal that amount Ti3+ (electron traps) is parallel evolution rate becomes a maximum for RC nanocrystals, which display highest...
The solvothermal reaction of magnesium(II) salts with formic acid in N,N-dimethylformamide/H2O at 140 °C for 24 h afforded two different polymeric formates, depending on the relative DMF/H2O content. A trigonal (space group R3̅c) anhydrous phase Mg(HCOO)2(HCOOH) ⊃ (CH3)2NH (1) is formed under "dilute" conditions, while orthorhombic Pbca) dihydrate Mg(HCOO)2·2H2O (2) main product when water content higher. When 2 dehydrated 300 and subsequently exposed to vapors, a quasi-reversible transition...
