We have first demonstrated that a random laser action generated by a hybrid film composed of a semiconducting organic polymer (SOP) and TiO(2) nanoparticles can be used to detect 2,4,6-trinitrotoluene (TNT) vapors. The hybrid film was fabricated by spin-casting SOP solution dispersed with nanosized TiO(2) particles on…
Using greige (scour/bleach-less) cotton, non-woven fabrics have been successfully produced by adopting conventional fiber opening, cleaning and (modified) carding machines followed by cross-lapping, pre/light needling, and hydro-entanglement (HE) on modern commercial machinery and equipment. Using standard test method…
Ce(OH) 3 open-hexagonal nanotubes [Ce(OH) 3 -OH-NT] and Ce(OH) 3 nanoporous-wall nanotubes [Ce(OH) 3 -NW-NT] have been successfully synthesized, for the first time, by a hydrothermal alkaline route and characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Br…
We report an atomistic simulation study of the behavior of nanocomposite materials that are formed by incorporating single-walled carbon nanotubes (SWCNTs), with three different diameters, and a multiwalled carbon nanotube (MWCNT) into a single-crystal nickel matrix. The interactions between carbon and nickel atoms ar…
The effect of excess MgO, 2.0–4.0 mol ratios on the crystallization behavior and purity of μ‐cordierite was investigated using X‐ray diffraction (XRD), differential thermal analyzer, and TGA. Quantitative XRD, the Rietveld technique, was carried out using the HighScore Plus software. The glass crystallization process…
Ni-decorated activated-carbon film is deposited directly onto the stainless steel substrate by using electrophoretic deposition (EPD) in the activated-carbon suspension containing nickel nitrate additive. The adsorption of nickel ions on the external surface and interior pores of activated carbons considerably increas…
Selection of navel rotor spinning machine, which influences various quality parameters of the final yarn, is a multi-criteria decision-making (MCDM) problem. Different statistical methods have been used in the past to address such kinds of problems. In this work, a suitable navel for denim fabrics was selected by comb…
Abstract Silver particles with different degrees of aggregation were synthesized through a sodium dodecyl sulfate‐assisted one‐pot reaction in an aqueous medium. The products were characterized by transmission electron microscopy, scanning electron microscopy and UV‐visible spectroscopy. The results showed that the de…
We report the first liquid−liquid Ullmann etherification process mediated not only by oxidatively stable Cu but also by CuZn and CuSn nanoparticle catalysts in conjunction with microwave heating that also avoids the use of solid and expensive bases. Conditions have led to improved turnovers and excellent yields in het…
Ferroelectric perovskite solid solutions with morphotropic phase boundary (MPB) have been studied extensively as best candidates for electromechanical transduction due to their exceptionally high piezoelectric coefficients. However, despite the high number of publications about these oxides, there is still ambiguity a…
Abstract Inorganic solids with porosity on the mesoscale possess a high internal surface area and a well‐accessible pore system. Therefore, it is a relevant task to equip the surfaces of such materials with a maximum density of various organic functional groups. Among these functions it is the capability of coordinati…
The SrFe(2)As(2 - x)P(x) (0.0 ≤ x ≤ 1.0) and CaFe(2)As(2 - y)P(y) (0.0 ≤ y ≤ 0.3) materials were prepared by a solid-state reaction method. X-ray diffraction measurements indicate that the single-phase samples can be successfully obtained for SrFe(2)As(2 - x)P(x) (0.0 ≤ x ≤ 0.8) and CaFe(2)As(2 - y)P(y) (0.0 ≤ y ≤ 0.3…
We report on the softening properties and viscosity of glasses from the system ZnO–Na 2 O–SO 3 –P 2 O 5 for low‐temperature sealing applications. Up to a ratio of network‐forming ions PO 4 3− :SO 4 2− of about 2:1, a gradual substitution of P 2 O 5 by SO 3 results in decreasing glass transition and softening temperatu…
A monolayer of dodecanethiol-stabilized gold nanoparticles changed into two-dimensional and three-dimensional self-organized structures by annealing at 323 K. Subsequent crystal growth of gold nanoparticles occurred. Thiol molecules, although chemisorbed, form relatively unstable bonds with the gold surface; a few thi…
A peptide containing a RGD (arginine-glycine-aspartic acid) sequence as well as a hydrophobic N-fluorenyl-9-methoxycarbonyl (FMOC) tail was prepared via a standard FMOC solid-phase peptide synthesis technique. The supramolecular self-assembly of such peptide through pi-pi stacking from FMOC tail can transfer the pepti…
A combination of two analytical methods, time-resolved X-ray diffraction (XRD) and Raman spectroscopy, is presented as a novel tool for crystallization studies. An acoustic levitator was employed as sample environment. This setup enables the acquisition of XRD and Raman data in situ simultaneously within a 20 s period…
Summary This work was intended to study the interaction between ferrous-iron and calcium ions simultaneously toward carbonate ions in supersaturated solution in a continuous stirred tank reactor (CSTR) and to establish an acceptable experimental design as a preparation step to study the kinetics of other types of ferr…
The effects of ion-beam bombardment on the physical and chemical properties of poly(allyl diglycol carbonate) (CR-39) polymer have been investigated. CR-39 samples were bombarded with 320 keV Ar and 130 keV He ions at fluences ranging from 1 × 1013 to 2 × 1016 ions/cm2. The nature and extent of radiation damage induce…
Variable pressure and temperature conductivity measurements on the bisthiaselenazolyl radical dimer [1a](2) have established the presence of a weakly metallic state over the pressure range 5-9 GPa. To explore the origin of this metallization we have examined the crystal and molecular structure of [1a](2) as a function…
Spacer technology, a self-aligned double patterning (SADP) technique, has been drawing more and more attention due to its less stringent overlay requirements compared to other double-patterning methods. However, use of SADP techniques was previously limited by the lack of flexibility in terms of decomposition options…
