Most commercial textile materials are given a “soft finish” for the comfort of the wearer. This paper investigates the effects of two levels of concentration for six commercial softeners on cotton knitted fabrics. The fabric properties are measured by using the Kawabata Evaluation System for Fabrics (KES-FB). It is fo…
The I ( V ) characteristics of amorphous GST devices show a peculiar S-shape behavior, that is a swift rise of the current along with a voltage snap-back. This type of characteristics led to a growing research interest in view of the future application of such materials to the manufacturing of phase-change memory devi…
In situ x-ray absorption spectroscopy identified partially oxidized platinum as the active phase for generating high activity during carbon monoxide oxidation over Pt/Al 2 O 3 . CO covers and poisons metallic platinum, which results in a low catalytic activity. The conversion in CO abruptly increased during ignition,…
This paper presents a program to simulate performance of a liquid phase catalytic exchange (LPCE) column of a water detritiation facility based on combined electrolysis and catalytic exchange (CECE) technology over a wide range of deuterium contents in a feed stream. The program uses rate constants of the chemical iso…
Cation Exchange Selectivity (CES) for Wyoming montmorillonite was determined by equilibration of the clay with a mixed equinormal solution containing two competing cations (i.e. Pb2+, Zn2+). This paper aims at characterizing the structural change and selectivity of a Na-dioctahedral smectite (Wy-Na). The quantitative…
X-ray absorption fine structure (XAFS) and first-principles calculations are effectively combined to establish correlations of fabrications, atomic and electronic structures as well as ferromagnetism for the Mn-doped dilute magnetic semiconductors (DMS), and to shed light on the magnetism origin for a variety of ZnO-,…
The focus of this study has been to fully describe the mechanical properties and behaviour of an extruded Wood Plastic Composite product. The use of plasturgy technologies for the elaboration of lignocellulose reinforced composites raises fundamental questions about the behaviour of these materials. Mechanical propert…
Abstract Mg–Al layered double hydroxide intercalated with 2,7-naphthalene disulfonate ion (2,7-NDS·Mg–Al LDH) was prepared by coprecipitation and was found to selectively take up aromatic compounds from aqueous solutions. The amount of material absorbed by 2,7-NDS·Mg–Al LDH depends on the electron-donating or -withdra…
The spectra of RE-doped YPO 4 (RE = Ce 3+ , Pr 3+ or Nd 3+ ) have been measured. The spectroscopic and decay kinetics properties of pure host YPO 4 were also studied at 8 K and 300 K, which indicated the host had taken part in the luminescent processes of activators. Under the excitation over the bandgap of the host,…
Complexes Ln(Phen)(C6F5COO)3 (Ln = Tb, Eu; Phen = 1,10-phenanthroline) (I, II) are synthesized. At 300 K these complexes and compounds Ln(C6F5COO)3 · nH2O (Ln = Tb, n = 2; Ln = Eu, n = 1) (III, VI) possess photoluminescence (bright in the case of I and II). In the spectrum of compound I the line at 545 nm (transition…
The intrinsic viscosity of chitosan (MW 7.9 x 105 g mol-1) having a high degree of deacetylation and solubilised in aqueous formic and acetic acids was determined at room temperature. Contact angle and conductivity of the chitosan solutions were also studied. The values of critical coagulation concentration (CCC) were…
Abstract magnified image Naphtho[2,1‐ b ]pyran nuclei are prevalent in natural products with significant biological and medicinal properties. 3,3‐Disubstituted 3 H ‐naphtho[2,1 ‐b ]pyrans are photochromic and find use in electronic display systems, ophthalmic lenses, optical switches, and temporary or permanent memori…
Four new alkyl-substituted 3,3′-bis(dipyrrolylmethene) dihydrobromides containing from 4 to 10 alkyl substituents were synthesized. In a highly alkylated ligand of these substances one of the hydrogen atoms of the 3,3′-methylene spacer was substituted with a phenyl group. The compounds obtained were studied by IR, 1 H…
Abstract The investigation of segregation and embrittlement at grain boundaries in metals is a research area with a long tradition. In recent times, the feasibility of computational studies on the atomic scale gave a new impetus to the community. In this feature article we summarize our contributions to the understand…
When producing thin ultra high strength steel components with the press hardening process, it is essential that the final component achieves desirable material properties. This applies in particular to passive automotive safety components where it is of great importance to accurately predict the final component proper…
Polypyrrole(PPy) thin films were deposited on vapor grown carbon fibers(VGCF). Formation of PPy on VGCF was carried out by using an in-situ chemical polymerization of the monomer in presence of FeCl3 oxidant. An ultrasonic cavitational stream was used during polymerization of pyrrole, to enable the deposition of unifo…
Abstract Tailor-made synthesis of Pd clusters in the subnanometer range was achieved using dendrimers as tunable host materials. The subnano Pd clusters consisting of a specific number of Pd atoms of Pd4, Pd8, and Pd16 were obtained by preorganization of Pd ions within the PPI dendrimers and subsequent reduction.
Radiation-initiated polymerization of tetrafluoroethylene (TFE) in acetone has been carried out in a specially designed reactor, which makes it possible to maintain a constant concentration of the monomer in a solution during synthesis. The features of the telomerization process at different initial concentrations (pr…
Arrays of low-dimensional molecular crystals of square columns (1-D) and nanolamellae (2-D) of Zn[TCNQ] 2 (H 2 O) 2 with large areas (up to 10 20 cm 2 ) have been synthesized by controlled addition of water to Zn and TCNQ. Based on the ability to accurately control the reaction, a new moisture and water indicator has…
Elaborately designed bilayers consisting of epitaxial YBa2Cu3O7−δ (YBCO) and La0.67Sr0.33MnO3−δ (LSMO) films were fabricated by pulsed laser deposition with respect to the investigation into magnetic-dependent vortex pinning effect. The improvement in the critical current density and a pronounced upward shift in the s…
