Background: After indirect capping, injured odontoblasts generate reactionary dentin, whereas after direct capping of a pulp exposure pulp, cells stimulate the formation of reparative dentin. The aim of this study was to evaluate and compare the effects of two direct capping agents on pulp tissue reactions: Hydrogel (a bovine serum albumin (BSA)/glutaraldehyde,) and Dycal (a calcium hydroxide-b...

Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...

In this investigation, CuInS2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. The CuCl, InCl3 along with (SC (NH2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (CH(CH2)17NH2) and oleic acid (CH(CH2)16COO...

Metal nanostructures have attracted great attention in various fields due to their tunable properties through precisely tailored sizes, compositions and structures. Using mesoporous silica (mSiO2) as the inorganic capping agent and encapsulated Pt nanoparticles as the seeds, we developed a robust seeded growth method to prepare uniform bimetallic nanoparticles encapsulated in mesoporous silica ...

The present invention is directed to a method for powder coating a metal substrate using a low-melt polyamic acid (PAA) polymer that readily imidizes to polyimides. These low-melt PAAs have been shown to be useful in resins applied as powder coatings to metal surfaces. The resin includes an end-capping material capable of providing crosslinking functionality to at least one end of the low-melt ...

Improvement of the new phosphite method for the synthesis of oligodeoxyribonucleotides using the deoxyribonucleoside 3'-bis(1,1,1,3,3,3- hexafluoro-2-propyl) phosphite unit has been carried out via the hydrolysis and capping steps, without any side reaction products. The new phosphite unit and capping agent, bis(1,1,1,3,3,3-hexafluoro-2-propyl)-2-propyl phosphite, is readily activated by N-meth...

In lymphocytes cap formation induced by concanavalin A (con A) was found to be concentration dependent on the mitogen in the presence of colchicine, a microtubule disrupting agent. The dose-respone of cap formation under these conditions was similar to mitogen dose-response. In addition, a direct correlation was found between con A capping induced in the presence of colchicine and mitogenic res...

We report the catalytic activity of colloid platinum nanoparticles synthesized with different organic capping layers. On the molecular scale, the porous organic layers have open spaces that permit the reactant and product molecules to reach the metal surface. We carried out CO oxidation on several platinum nanoparticle systems capped with various organic molecules to investigate the role of the...

Multiple analyses discussed using MTA as direct capping material. These reports have shown that MTA is a promising material for the preservation of pulp tissue when used as a direct capping material. Many clinical studies have demonstrated successful outcomes after the use of MTA as a capping agent on mechanically or cariously exposed pulps. The studies performed by us in this research focused ...

CuAlS2  Chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  The  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  The  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. The nanoparticles were  synthesized with CuCl, AlCl3 and  thiourea (SC(NH2)2...
