This chapter describes a comprehensive computational study on the template-assisted and Pd(OAc)2-catalyzed meta-selective C–H olefination reaction. The reaction mechanism, the active form of catalyst, the potential role of silver salt and the origin of meta-selectivity were investigated in this work. The computational results demonstrated that the conventionally proposed monomeric Pd(OAc)2 mode...

One of the most common causes of implant failure is peri-implantitis, which is caused by bacterial biofilm formation on the surfaces of dental implants. Modification of the surface nanotopography has been suggested to affect bacterial adherence to implants. Silver nanoparticles are also known for their antibacterial properties. In this study, titanium alloy implants were surface modified follow...

A screen-printed dissolved oxygen sensor was fabricated using cerium oxide-supported silver catalyst and polydimethylsiloxane (PDMS) film. A PDMS film of 3 µm thickness showed good permeability for oxygen and impermeability for hydrogen peroxide. The calibration curve has shown a linear relationship with a correlation coefficient of 0.996 for the dissolved oxygen concentration. The sensitivi...

Background: According to the poison center data for most countries, more than thousands of people’s exposure aspirin or salicylate-containing products. So, this work aimed was offer a rapid colorimetric method monitoring concentration in exhaled breath condensate (EBC). Methods: A based on redox reaction catalyzed by nanoparticles validated analysis aspirin. 3,3 ,5,5 –Tetramethyl benzidine /H2 ...

Mordenite (H-MOR) catalysts were synthesized by a hydrothermal method, and silver-modified mordenite (Ag-MOR) prepared ion exchange with AgNO3 at different concentrations. The performance of these in the carbonylation dimethyl ether (DME) to methyl acetate (MA) was also evaluated. characterized Ar adsorption/desorption, XRD, ICP-AES, SEM, HRTEM, 27Al NMR, H2-TPR, NH3-TPD, Py-IR, CO-TPD. Accordi...

A silver-free methodology was developed for the synthesis of unprecedented N-heterocyclic carbene ruthenium indenylidene complexes bearing a bidentate picolinate ligand. The highly stable (SIPr)(picolinate)RuCl(indenylidene) complex 4a (SIPr = 1,3-bis(2-6-diisopropylphenyl)imidazolidin-2-ylidene) demonstrated excellent latent behaviour in ring closing metathesis (RCM) reaction and could be acti...

We report on the photoconductive response of nanostructured sol-gel films in function of the silver nitrate concentration (ions and colloids). Silver colloids were obtained by spontaneous reduction process of Ag+ ions to Ag(0). 2-d hexagonal nanosructured sol-gel thin films were prepared by dip-coating method using the non-ionic diblock copolymer Brij58 to produce channels into the film, which ...

Copper(I) and nickel(0) complexes catalyze the formal [4 + 2] cycloaddition reactions of 1,2-diazines and siloxyalkynes, a reaction hitherto best catalyzed by silver salts. These catalysts based on earth abundant metals are not only competent, but the copper catalyst, in particular, promotes cycloadditions of pyrido[2,3-d]pyridazine and pyrido[3,4-d]pyridazine, enabling a new synthesis of quino...
