Growing interest in transporting supercritical carbon dioxide (scCO2) for enhanced oil recovery and carbon capture and storage has led to an increased interest in the corrosion behavior of pipeline steels at varying levels of water contamination. Electrochemical measurements in scCO2 fluids have been limited by low so…
Trigger factor is the first molecular chaperone interacting cotranslationally with virtually all nascent polypeptides synthesized by the ribosome in bacteria. The stability of this primary folding assistant was investigated using trigger factors from the Antarctic psychrophile Pseudoalteromonas haloplanktis, the mesop…
The aim of this work is to analyse and evaluate the contribution of some knitting machine and yarn structure parameters on the residual bagging height using an experimental Taguchi design method. Besides, the effects of each input parameter as well as their interactions are discussed. In our experimental field of inte…
Abstract A cation‐exchanged montmorillonite clay is prepared as filler material with high dispersibility, that should act as Fe3+‐donor for photochemical crosslinking of PVA/Fe3+‐MMT materials with filler contents of up to 50 wt % with regard to the polymer matrix. Hence, no organic photoinitiators and hazardous compo…
The present communication reports the hydrogen storage characteristics of ZrMn2−xNi x laves phase hydrides. It is observed that promising hydrogen storage materials can be tailored when “x” is in the range of 1.5 ≤ x ≥ 1. The materials formed within this range reversibly store ~2 to ~3 H/F.U. under manageable operatin…
A series of organically templated vanadium tellurites has been prepared under mild hydrothermal conditions. Single crystals were grown from mixtures of NaVO 3, Na 2 TeO 3, and either 1,4-diaminobutane, 1,6-diaminohexane, or N, N, N ′, N ′-tetramethylethylenediamine in H 2 O. Each compound contains similar [V 2 Te 2 O…
A new polyfluorene derivative containing pendent alkylating chlorambucil (PFP-Cbl) was synthesized and characterized. Under direct incubation with DNA in vitro, PFP-Cbl could undergo an efficient DNA alkylating reaction and induce DNA cross-linking. In vitro transcription and translation experiment exhibited that the…
The alkaline decomposition of hexathionate has been investigated by high-performance liquid chromatography monitoring the concentration of polythionates (such as hexathionate, pentathionate, and tetrathionate) and that of thiosulfate simultaneously in buffered medium at a constant ionic strength. As a major final prod…
Abstract Expanded graphite (EG) is prepared by microwave irradiation to expandable graphite. A stable aqueous suspension of EG is obtained through dispersing EG into deionized water in the presence of surfactant under ultrasonication. Nanocomposites are prepared by compounding EG aqueous suspension with alkyl acrylate…
We describe a simple but effective strategy for imparting light-responsive peculiarity to polystyrene films. A pH-sensitive fluorescent dye having the electron-poor pyridine nucleus as a key structural feature was synthesized and dispersed at low loadings (0.2-0.5 wt %) in a PS matrix. Once light irradiation in the ne…
Abstract Introducing well‐defined polymeric side chains to bisterpyridine coordination polymers enables the synthesis of materials with tailor‐made optical and mechanical properties. The polymers are introduced either by a copper‐catalyzed azide–alkyne cycloaddition (grafting‐onto) or an atom transfer radical polymeri…
We have investigated the post heat treatment effect of electrochemically prepared cupric oxide (CuO) thin films. The films were annealed at different temperatures ranging from 200 to 400°C in air medium. The annealed films structural, optical, compositional and morphological properties were studied. X-ray diffraction…
We find the spontaneous binding of single DNA molecules to uncoated silver nanoparticles (AgNPs) in aqueous solution with Mn(2+) (3 mM). From dark-field optical microscopic imaging of AgNPs bound to DNA molecules, we demonstrate analysis of the Brownian motion of single DNA molecules via plasmon resonance elastic ligh…
Various superimposed chirped relief gratings, acting as diffracting holographic lenses, were photo-inscribed on azo-polymer films upon exposure to the interference pattern of a plane and a curved laser light wavefronts. Depending on the configuration used, this resulted in incident light being focused independently of…
Abstract The freeze‐drying combining solid sintering is a good method to fabricate porous SiC ceramics with good high temperature mechanical properties. Though SiC ceramics are sintered at a high temperature of 2150 °C, there are still large quantity of macropores generated by sublimating large ice crystals and microp…
We report the results of our studies on the optical and thermal properties of the mixture of cholesteryl nanonate, cetyl-dimethyl-ethylammonium bromide, and ethylene glycol, which exhibits very interesting liquid crystalline mesophases like cholesteric (N*) and induced smectic phases, such as SmA, SmC*, SmE, and SmB,…
The transport and accumulation of anticancer nanodrugs in tumor tissues are affected by many factors including particle properties, vascular density and leakiness, and interstitial diffusivity. It is important to understand the effects of these factors on the detailed drug distribution in the entire tumor for an effec…
A new high temperature rechargeable “metal-air” battery has recently been proposed as a new mechanism for grid energy storage. This new battery consists of a regenerative solid oxide fuel cell (RSOFC) and a metal/metal oxide redox couple. In this paper we present the working principle, thermodynamic and kinetic perspe…
Abstract The poly‐hematoxylin films undoped (p‐HX) and doped with strontium (p‐HX‐Sr) were prepared on the platinum electrodes (Pt) using cyclic voltammetry. The influence of experimental parameters, such as: anodic potential and number of voltammetric cycles on the films synthesis was investigated by electrochemical…
Fluorescence quenching microscopy (FQM) is demonstrated as a low-cost and high-throughput technique for seeing graphene-like 2D sheets such as MoS2 . FQM provides high contrast and layer resolution comparable to those of scanning electron microscopy, but allows the imaging of samples deposited on arbitrary substrates,…
