moisture-wicking, temperature-controlling characteristics and so on, warp knitted spacer fabric (in short WKSF) is moving into the cushion market, which is dominated by PU-foam and may be a popular cushion material used in furniture in the future. Therefore, the goal of this research is to provide a model that can pre…
This paper describes the tethering of ferrocene (Fc) onto polycrystalline gold electrodes by immobilized polyamidoamine (PAMAM) dendrimers films. The resulting electroactive surface provides a viable route for investigating quantitatively the host-guest binding of ferrocene with cyclodextrin (CD). In particular, elect…
In this contribution we explore the capability of biocompatible nanoparticles (NPs) of cationic amphiphilic cyclodextrins entangling the anionic hydrophilic 5,10,15,20-tetrakis(4-sulfonatophenyl)-21H,23H-porphyrin (TPPS) to facilitate photoinduced energy and electron transfer with suitable donor and acceptor guest mol…
A simple and general approach for controlling optical anisotropy of nanostructured semiconductors is reported. Our design involves the fabrication of liquid crystal devices with built-in semiconductor nanotubes. Quite interestingly, it is found that semiconductor nanotubes can be well aligned along the orientation of…
Parallel factor analysis (PARAFAC) was used to analyze data from the high throughput screening of an array of organometallic rhodium and iridium complexes as catalysts for the intramolecular hydroamination of 2-(2-phenylethynyl)aniline to give 2-phenylindole. The progress of the hydroamination reactions was monitored…
To apply the power-law to random mixing composites, the power parameter α is defined as the mean depolarization factor along the external field.The formula of α is derived from the effective medium theory and beta function distribution assumption to study the geometrical influence of scatterers.According to the simula…
An ultrasound technique to measure the spatial and temporal behavior of the laser-induced cavitation bubble is introduced. The cavitation bubbles were formed in water and in gels using a nanosecond pulsed Nd:YAG laser operating at 532 nm. A focused, single-element, 25-MHz ultrasound transducer was employed both to det…
Cerium oxide conversion coatings were deposited on aluminum alloy 2024‐T3 panels from an aqueous solution using a spray process. Substrate cleaning temperature was varied to evaluate its effect on deposition. Coating thickness did not increase linearly with the number of spray cycles. Deposition rate increased after f…
We demonstrate herein the fabrication of patterned layers of Zn2SiO4:Mn2+ and Y2SiO5:Eu3+ phosphor materials based on nanostructured diatom biosilicavia the inkjet printing process.
This paper aims to address the problem of equipment fault prevention by preventive diagnosis of its insulation. Preventive diagnosis, as the name implies, means the accurate judgment made in advance on when power equipment can be replaced from on-site service before its breakdown. The experimentation, via voltage-stre…
The functionalization of carbon nanotubes through electrochemical routes is gaining importance due to the high degree of control achievable and the ability to render the tubes with a variety of chemical and biological species. In this article, we report systematic investigations on the grafting of phenyl groups throug…
To modify properties of polyvinyl chloride, its chlorine atoms were substituted using sodium salts of pyrazole, 3,5-dimethylpyrazole, and 2-mercaptobenzimidazole.
Single-walled carbon nanotubes (SWCNTs) were suspended in aqueous media with cucurbit[7]uril (CB7), while SWCNTs were insoluble with cucurbit[5]uril (CB5). Moreover, defection-selective solubilization of SWCNTs with CB7 was demonstrated.
A method for the elaboration of a heterojunction composed on n-type inorganic semiconducting nanoparticles, TiO(2), and a p-type organic semiconducting polymer poly(3,4-ethylene dioxythiophene) by UV illumination is described.
Bimetallic Au-Pt nanoparticles have been generated inside a relatively porous SiO2 film matrix by a two-layer (2L) coating methodology. Two overlapping coating layers were deposited on glass substrates from Au- and Pt-doped inorganic-organic hybrid silica sols and air dried at 60 degrees C. The 2L coating assembly was…
As-deposited films were prepared on sapphire substrates at 500–680 °C by alternately sputtering Cu and Al targets in Ar-diluted O 2 gas atmosphere. The composition of the as-deposited films corresponded to that of the slightly oxygen-rich region of the CuO–CuAl 2 O 4 –Al 2 O 3 system. The films as-deposited at 500 °C…
In this study, we propose a new hybrid process consisting of glycolysis/methanolysis and then a vapor methanolysis process to obtain dimethyl terephthalate (DMT) and ethylene glycol (EG) in the depolymerization of waste poly(ethylene terephthalate) (PET). Zinc acetate was used to catalyze the reactions. We found that…
The study of the substitution of manganese by cobalt in the perovskite (LaBi)MnO3 in view of discovering magneto-dielectric properties in manganites, has allowed the perovskite La1.2Bi0.8Mn1.2Co0.8O6.02 to be selected. This phase is indeed ferromagnetic, like the parent phase La1.2Bi0.8Mn2O6.20, yet with a much higher…
Multiwalled carbon nanotube (MWCNT) films have been deposited by using plasma‐enhanced chemical vapor deposition (PECVD) system onto alumina substrates, provided with 6 nm thick cobalt (Co) growth catalyst for remarkably improved NO 2 gas sensing, at working temperature in the range of 100–250 ∘ C. Functionalization o…
Density functional theory (DFT) calculations, regardless of the exchange-correlation functional, have long failed to reproduce the observed dz2(1) ground state of the [NiIII(TtBuP)(CN)2]- anion (where TtBuP is the strongly ruffled tetra(tbutyl)porphyrin ligand), predicting instead a dx2-y2(1) ground state. Normally, s…
