روش های معمول برای تهیه بنزوتیازول ها شامل تراکم 2-آمینوتیوفنول با کربوکسیلیک اسید ها، آلدهید ها و هم¬چنین ارتواسترها می باشد. در این کار، کاتالیست nano- γ-al2o3/bf3-n به عنوان کاتالیست اسید جامد تهیه شده است. برای تایید ساختار nano- γ-al2o3 و nano- γ-al2o3/bf3-n طیف مادون قرمز و پراش پرتو xگرفته شده است. مشتقهای بنزوتیازول از طریق تراکم آلدهید ها با 2-آمینوتیوفنول با استفاده از nano- γ-al2o...
Filamentous biopolymer networks in cells and tissues are routinely imaged by confocal microscopy. Image analysis methods enable quantitative study of the properties of these curvilinear networks. However, software tools to quantify the geometry and topology of these often dense 3D networks and to localize network junctions are scarce. To fill this gap, we developed a new software tool called "S...
We report the current–voltage characteristics of gold nanoparticle–biopolymer networks at room temperature. The characteristics have features that are indicative of single-electron charging in ordered, one-dimensional chains of nanoparticles. From capacitance estimates and numerical simulations, we argue that the observed electrical behavior is related to the low size dispersion of the nanopart...
We present a detailed description of biopolymer translocation through a nanopore in the presence of a solvent using an innovative multiscale methodology that treats the biopolymer at the microscopic scale as combined with a self-consistent mesoscopic description for the solvent fluid dynamics. We report evidence for quantized current blockade depending on the folding configuration and offer det...
In this review the dispersability of carbon nanotubes in aqueous solutions containing proteins, or nucleic acids, is discussed. Data reported previously are complemented by unpublished ones. In the mentioned nanotube-based systems several different phases are observed, depending on the type and concentration of biopolymer, as well as the amount of dispersed nanotubes. The phase behavior depends...
