SnO2/PbOx (x = 1, 2) Core–Shell Nanowires and Their Growth on C-Fiber Networks for Energy Storage
(2018)
SnO2 nanowires were grown on Si, fused SiO2, and C fibers by the vapor–liquid–solid mechanism at 800 °C and 10–1 mbar, and SnO2/PbO core–shell nanowires were obtained by the deposition of 50 nm Pb over the SnO2 nanowires ...
Bis(hydroxylamino)triazines: High Selectivity and Hydrolytic Stability of Hydroxylamine-Based Ligands for Uranyl Compared to Vanadium(V) and Iron(III)
(2018)
The development of ligands with high selectivity and affinity for uranium is critical in the extraction of uranium from human body, radioactive waste, and seawater. A scientific challenge is the improvement of the selectivity ...
From colloidal aggregates to layered nanosized structures in polymer-surfactant systems. 1. Basic phenomena
(2001)
In this work, we examine the rich crystallization behavior that occurs in PbII/S-II/poly(ethylene oxide) (PEO)/sodium dodecyl sulfate (SDS) systems, in which the anionic surfactant interacts strongly with the polymer ...
Composite nanotubes formed by self-assembly of PbS nanoparticles
(2003)
Unusual arrangements of nanoparticles were observed during the synthesis and subsequent dissolution of PbS particles under the action of the surfactant sodium dodecyl sulfate (SDS) in solutions containing hydrophilic ...
Optical properties of polyelectrolyte quantum dot multilayer films prepared using the layer by layer self-assembly method
(2008)
In this work, we have used spectroscopic ellipsometry to study the optical properties of polyelectrolyte-PbS quantum dot (QD) multilayer films prepared using the layer by layer self-assembly method. The optical results ...
Monolayer properties of surface-active metalorganic complexes with a tunable headgroup
(2008)
Surface-active metalorganic complexes can be used to construct organic thin films with excellent electronic and catalytic properties. We have recently introduced a new versatile surface-active ligand, which can efficiently ...
A normal-mode study of a polymer glass containing a chromophore impurity
(1996)
We examine the vibrational density of states of atomistic models of polypropylene glasses containing a single impurity molecule of s-tetrazine. We discuss existing methods and develop new ones to achieve significant data ...
Formation mechanism of nanotubes comprising layers of PbS nanoparticles in polymer-surfactant solutions
(2006)
The crystallization of PbS in aqueous solutions containing the surfactant sodium dodecyl sulfate (SDS) and hydrophilic polymers resulted in a novel type of metastable nanotubes, the walls of which consist of layers of ...
Double Networks Based on Amphiphilic Cross-Linked Star Block Copolymer First Conetworks and Randomly Cross-Linked Hydrophilic Second Networks
(2016)
This study presents the preparation and characterization of double networks (DN) based on a first amphiphilic polymethacrylate conetwork (APCN) and a second polyacrylamide network. The APCN first network comprised ...
Controlled production of ZnO nanoparticles from zinc glycerolate in a sol-gel silica matrix
(2006)
The controlled production of ZnO nanoparticles within an amorphous silica matrix is achieved using a new methodology consisting of four stages. First, precursor zinc glycerolate nanoparticles are produced within reversed ...
