We have studied the electrical and optical characteristics of cells filled with nematic liquid crystal (NLC) based on cyanobiphenyls with positive dielectric anisotropy, containing dispersed 3.5-nm-sized CdSe/ZnS composite semiconductor nanoparticles (quantum dots, QDs) with a concentration of 0.1–0.2 wt %. In additio…
The IR vibrational properties and the corresponding reflectance spectra of the six most common members of the garnet family (pyrope Mg 3 Al 2 Si 3 O 12 , almandine Fe 3 Al 2 Si 3 O 12 , spessartine Mn 3 Al 2 Si 3 O 12 , grossular Ca 3 Al 2 Si 3 O 12 , uvarovite Ca 3 Cr 2 Si 3 O 12 , and andradite Ca 3 Fe 2 Si 3 O 12 )…
GCMS study of Anogessus leocarpus gum (AL gum) indicated the presence of sucrose (10.03 %), phthalic acid (2.53 %), n-hexadecanoic acid (11.73 %), oleic acid (30.49 %), pentacenequinone (4.41 %) and 2,3- diphenylnaphthoquinone (21.43 %). The gum was found to be a good adsorption inhibitor for the corrosion of mild ste…
Abstract— The current status of AC powder electroluminescent (ACPEL) displays is reviewed with particular emphasis given to color and lifetime. The printing of the displays in forward and reverse architectures is also discussed, in addition to the fabrication of ACPEL displays with interdigitated electrodes, and diffe…
We report here the preparation and structural models of alkaline-earth (Ca 2+ , Sr 2+ , Ba 2+ ) and heavy metal (Cd 2+ , Pb 2+ , Ag + ) cation-exchanged natrolites at ambient conditions and compare them to the alkali (Li + , Na + , K + , Rb + , Cs + ) cation forms. The latter two groups all crystallize in the orthorho…
ZnO nanorods have been prepared by electrodeposition under identical conditions on various p-GaN-based thin film structures. The devices exhibited lighting up under both forward and reverse biases, but the turn-on voltage and the emission color were strongly dependent on the p-GaN-based structure used. The origin of d…
In this paper we report a synoptic methodology to evaluate and optimize the long-range order induced by graphoepitaxy of block copolymer (BCP) self-assembly. The authors focus the study on a BCP that produces hexagonally packed arrays of cylinders oriented perpendicular to the substrate with the copolymer film thickne…
Metalated and free-base A(3)B-type asymmetric phthalocyanines (Pcs) bearing, in the asymmetric quadrant, a flexible alkyl linker of varying chain lengths terminating in a phosphonic acid (PA) group have been synthesized. Two parallel series of asymmetric Pc derivatives bearing aryloxy and arylthio substituents are rep…
Hydroxyls are present as surface terminations of transition metal oxides under ambient conditions and may modify the properties of supported catalysts. We perform first-principles density functional theory calculations to investigate the role of hydroxyls on the catalytic activity of supported gold clusters on TiO 2 (…
The dynamic response of VO2-coated silicon microcantilevers thermally driven over the film’s insulator-to-metal transition was studied using laser light pulses directly incident on the cantilevers. The measured photothermal response revealed very high curvature changes of approximately 2500 m−1 up to pulse frequencies…
Heterogeneous acetylation to a low extent of bleached and unbleached commercial kraft pulps was performed with acetic anhydride without solvents and in the presence of sulfuric acid catalyst. The process was conducted in an effort to change the polarity of studied kraft pulps and to improve their compatibility with sy…
Over 50 years of nuclear fuels and materials irradiation testing has led to many countries developing significant improvements in instrumentation to monitor physical parameters and to control the test conditions in material test reactors (MTRs). Recently, there is increased interest to irradiate new materials and reac…
Equations resembling the Rayleigh-Plesset and Keller-Miksis equations are frequently used to model bubble dynamics in confined spaces, using the standard inertial term RR+3R([middle dot]) (2)/2, where R is the bubble radius. This practice has been widely assumed to be defensible if the bubble is much smaller than the…
The corrosion inhibition properties of ceftadizime (CZD) for mild steel corrosion .in H2SO4 solution were analysed by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and gravimetric methods. Mixed mode of adsorption (Physisorption and chemisorption) is proposed for the inhibition and the pro…
Although the viscosity of molten metal is very important, the measurement is considerably difficult for high temperature melts. The author's group has developed an oscillating viscometer for high temperature metal. The prediction of the viscosity behavior of the alloys is most useful task because the experimental data…
The Soret maxima of a number of metallotriarylcorroles shift sensitively in response to varying substituents on the meso-aryl groups. The effect is most pronounced for copper corroles but is not seen for silver and gold corroles. In the copper case, the effect has been attributed to a small HOMO–LUMO gap. Chromium-oxo…
Amine-terminated generation 5 poly(amidoamine) dendrimers were utilized as a platform to conjugate fluorescein isothiocyanate and lactobionic acid. The conjugated lactobionic acid moieties enabled effective targeting to human liver cancer cells (HepG2) in vitro, which was demonstrated by both flow cytometry and confoc…
BACKGROUND: The purpose of this study was to develop intraperitoneal hyperthermic therapy based on magnetic fluid hyperthermia, nanoparticle-wrapped cisplatin chemotherapy, and magnetic particles of albumin. In addition, to combine the multiple-killing effects of hyperthermal targeting therapy, chemotherapy, and radio…
The objective of this study was to investigate the inhibitive action of eggplant peel extract toward the corrosion of mild steel in 2M HCl solution by employing weight loss measurements and electrochemical techniques. The results of both methods showed that the corrosion rate is decreasing and inhibition efficiency is…
