Zinc Oxide (ZnO) nanorods and titanium dioxide (TiO2) nanostructures thin films were prepared onto glass substrates by the chemical bath deposition (CBD) method. The ZnO was structured as nanorods (NRs) while TiO2 was formed as nanoflowers plate as confirmed by Field-Emission Scanning Electron Microscope (FESEM) images. The ZnO/Fe3O4 and TiO2/Fe3O4 nanostructures thin films were prepared v...

A pyridinium-pended conjugated polyelectrolyte with photo-induced amine doping behaviour was designed for multiple applications.

It is already known that modification of E. col i polynucleotide phosphorylase by endogenous proteolysis induces drastic changes in both phosphorolysis and polymerisation reactions. The structural parameters of the proteolysed polynucleotide phosphorylase are described. The phosphorolysis of polynucleotide, which is quite progressive for the native enzyme, is shown to be only partially progress...

The enzyme, polynucleotide phosphorylase, catalyzes the polymerization of nucleoside diphosphates to polyribonucleotides with the formation of inorganic orthophosphate (1, 2). The reaction is readily reversible, and the phosphorolysis of polyribonucleotides has been studied extensively (3-6). Several recent reviews (7-9) afford extensive summaries of the literature. In the accompanying paper (l...

The signature sequence amplification method (SSAM) described herein is an approach for amplifying noncoding RNA (ncRNA), microRNA (miRNA), and small polynucleotide sequences. A key point of the SSAM technology is the generation of signature sequences. The signature sequences include target sequences (miRNA, ncRNA, and/or any small polynucleotide sequence) flanked by two DNA fragments. Target se...

nowadays various methods are presented for synthesis of barium strontium titanate (bst) nanopowders with different morphology and properties. each of these (bst)s has got individual characterization that makes it suitable for a special application. every method has a special quality, causes it to have preference over the other methods. low processing temperature is a desired point which most of...

Fluorescence measurements with single-molecule sensitivity are used to measure the hydrodynamic size and local pH of a weak polyelectrolyte, poly-2-vinyl pyridine end labeled with pH-sensitive dye, the polyelectrolyte having concentration so low (nanomolars) that molecular properties are resolvable only from fluorescence experiments and cannot be accessed by light scattering. We find that the l...

In this work we develop a field-theoretic methodology, which combines the concept of Gaussian equivalent representation for functional integrals with the continuous Gaussian thread model of flexible polymers for solving statistical-mechanical problems of polyelectrolyte solutions. We demonstrate the applicability of the method for systems of polyelectrolyte chains where the monomers interact vi...
