The purpose of this paper is to evaluate the inhibitive action of an ethanol extract from the leaves of Pachycormus discolor (EEPD) on the corrosion of carbon steel in 1 M HCl at different temperatures; gravimetric method and electrochemical tests were conducted. Potentiodynamic polarization was used at room temperatu…
Molecular interaction with metal surfaces raises fundamental questions regarding their binding tendency, their dispersion on the surface, as well as their conformation which may change their biological properties; addressing these questions, and being able to tune protein interactions, is of primary importance for the…
Eu doped strontium Aluminate phosphors were synthesized by combustion method using urea as a reducer at initiating temperature of 600 o C. We have investigated the Fracto-Mechanoluminescence (ML) and Thermoluminescence (TL) of SrAl 2 O 4 : Eu. Two peaks have been found in time Vs ML intensity plot. The peak of ML inte…
Growth and assembly of inorganic materials with the guidance of biomolecules is a promising route to control over the arrangement of nanoparticles. We present in this article an effective and efficient method for producing zinc oxide (ZnO) nanoparticle chains by directly using DNA as guide. Using extensive experiments…
Abstract Using cylindrical specimens with short gauge length, bulk cavitation is successfully generated in high‐density polyethylene copolymers (HDPE) under tensile loading. The bulk cavitation is generated without the presence of sharp notch, and therefore, crack growth is not involved in the rupture process. The bul…
Using solid-state reaction at low temperature (SSRLT), mesoporous chromium phosphates were successfully synthesized in the presence of a surfactant template, cetyltrimethyl ammonium bromide (CTAB), at a temperature of 353 K without using a water solvent. The synthesized chromium phosphates were characterized by XRD, E…
A new synthesis of [3]ferrocenophan-1-one has been developed, and a Trofimov reaction has been applied to its ketoxime. The novel subsequent N -vinyl pyrrole ferrocenophane displays reversible electrochemical behavior centered on the ferrocene, without any participation of the pyrrole. Unexpected byproduct was also is…
We present data from molecular dynamics simulations concerning the nonstationary response of polymer–brush bilayers to shear inversion. Bilayers with implicit solvents, dimeric solvents, and colloidal inclusions are subject to a quasi-instantaneous inversion of the shear direction, which mimics a highly nonstationary…
Porphyrin molecules, of interest as versatile materials for organic electronics, are highly prone to formation of significantly different polymorphic phases. To elucidate the determinants for the specific polymorphic phase formed in thin films as well as for the arrangement of the molecules on a given substrate two di…
This paper presents an oil/water interface self-assembly strategy for the fabrication of hydrophobic nanoparticles into mono- and multi-layered nanofilms with NaYF4:Yb,Er nanoplatelets as a prototype. In this approach, hydrophobic β-NaYF4:Yb,Er nanoplatelets dispersed in chloroform solvent are used as the sub-phase, t…
Phosphonium-based bolaamphiphiles have been found to stabilise silicic acid beyond its solubility limit (∼150 ppm). Three bolaamphiphiles have been tested having a quaternary phosphonium group on each end, linked by a number of ethylene oxide (EO) units (5, 21, and 91, resulting in PEGP+-200, PEGP+-1000, and PEGP+-400…
We report a simulation study for bottle-brush polymers grafted on a rigid backbone. Using a standard coarse-grained bead-spring model extensive molecular dynamics simulations for such macromolecules under good solvent conditions are performed. We consider a broad range of parameters and present numerical results for t…
Nanoporous alumina which was produced by a conventional direct current anodization [DCA] process at low temperatures has received much attention in various applications such as nanomaterial synthesis, sensors, and photonics. In this article, we employed a newly developed hybrid pulse anodization [HPA] method to fabric…
There has been a tenacious search for pharmaceuticals of natural origin, as they are cost-effective and are noted for having little or no side effects. The rate at which diseases are developing resistance to synthetic drugs is quite alarming, and the side effects of these drugs remain an excruciating agony to the phar…
An RF magnetron sputtering technique was used to deposit Ge and stacked Si/Ge films for infrared imaging sensors; the electrical characteristics of these films were estimated. The cross-sectional scanning electron microscope (SEM) image obtained confirmed that a layered Si/Ge structure was deposited on the SiO 2 subst…
Abstract A dendritic monomer with bipolar side groups containing dendritic carbazole and oxadiazole structures was synthesized by a convergent strategy. The homopolymer was synthesized through a conventional radical polymerization. The number‐average molecular weight determined by gel permeation chromatography was 40,…
Abstract Tungsten trioxide (WO 3 ) films with novel dandelion‐like structures were prepared by spin‐coating a sol of WO 3 with CTAB (cetyltrimethyl ammonium bromides) on quartz substrates. The resultant WO 3 films were characterized by X‐ray diffraction (XRD), FT‐IR spectroscopy, scanning electron microscopy (SEM), an…
Abstract The structure of a small marine planktonic centric diatom belonging to the genus Thalassiosira was characterised using electron microscopy; and data on its ultrastructure, autecology and initial valve formation are provided here. Although our specimens shared some characteristics with Thalassiosira proschkina…
An investigation is reported of the visible and near-infrared upconversions in Tm3+/Yb3+ co-doped double-clad silica fibers (TYDFs) under excitation at 980 nm. The TYDFs used were fabricated using the modified chemical vapor deposition (MCVD) and solution doping techniques. Three distinct upconversion luminescences we…
Although the effects of p-sulfonated and p-phosphonated calix[4]arene on barium sulfate morphology are similar, their ability to form mesocrystals of material are markedly different. The p-phosphonated calix[4]arene results in the formation of fibre bundles similar to those previously observed during barium sulfate cr…
