BF3/nano-γ-Al2O3 Promoted Knoevenagel Condensation at Room Temperature
The Knoevenagel condensation of aromatic aldehydes with barbituric acid, dimedone and malononitrile occurred in the presence of BF3/nano-γ-Al2O3 at room temperature in ethanol. This catalyst is characterized by powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and energy-disper...
متن کاملEffect of oxygen penetration in silicon due to nano-indentation
This paper aims to explore the effect of O2 on the nano-indentation of diamond cubic silicon using molecular dynamics simulation. Obtained with the aid of the Tersoff potential for Si–Si interactions and the Morse potential for all other interactions, the results show that on indentation, the O2 molecule in the appropriate position and orientation dissociates into oxygen atoms, penetrates into ...
متن کاملNano-indentation of a room-temperature ionic liquid film on silica: a computational experiment.
We investigate the structure of the [bmim][Tf(2)N]/silica interface by simulating the indentation of a thin (4 nm) [bmim][Tf(2)N] film by a hard nanometric tip. The ionic liquid/silica interface is represented in atomistic detail, while the tip is modelled by a spherical mesoscopic particle interacting via an effective short-range potential. Plots of the normal force (F(z)) on the tip as a func...

متن کاملBiomimetic synthesis of 1-aryl-2,5-dimethyl pyrroles using egg white nano-ovalbumin at room temperature under solvent-free conditions
Ovalbumin, as the major component of egg-white, is a globular, biocompatible, nontoxic and biodegradable phosphoglyco protein. This protein with the molecular weight of 44.5 kDa, contains 385 residues of amino acids with isoelectric point (pI) of 4.5. Many purification procedures have been reported for egg-white proteins such as gel permeation and anion exchange chromatography. In this study, w...
