Vacuum extraction is a technique that removes the unbound water from the fabrics by the help of air flow through the fabrics at high velocities. Air flow through textile fabrics is mainly affected by the fabric structure such as tightness, porosity and air permeability. This paper outlines the effects of the fabric st…
Of the methods employed in the preparation of one-dimensional lanthanide phosphate (LnPO(4)) nanorods/nanowires, such as GdPO(4), the hydrothermal method has been mainly used as a synthetic route. In this study, we report a facile low-temperature solution approach to prepare GdPO 4*H(2)O nanorods by simply refluxing G…
The stability of the recently discovered h-BN/Ru(0001) nanomesh is of crucial importance for potential applications as a nanotemplate. In particular, thermal stability in oxygen environment is important for nanocatalysis applications. We report here on the etching experiments of the h-BN layer by molecular oxygen expo…
This paper reviews the theoretical background of an approximate treatment of relativistic effects within the tight-binding (TB) linear muffin-tin orbital (LMTO) method for ab-initio electronic structure calculations of solids. The formalism employs two-component spinors and an orbital basis set of the scalar-relativis…
Insertion of nickel(II), zinc, cadmium, or silver(III) into both macrocyclic crevices of 2,2'-o-xylene-bis(5,10,15,20-tetrakis(p-tolyl)-2-aza-21-carbaporphyrin) results in homometallic dimeric complexes which were isolated and characterized by NMR, UV-vis, mass spectrometry, and cyclic voltammetry. The 1H NMR study of…
The aim of the paper is to observe the effects of convection on the total heat transfer of the fabric. Convective heat transfer through textiles can be simulated with the help of computational fluid dynamics (CFD). The first part of this paper has dealt with the mathematical model for predicting the conductive and rad…
The synthesis and thermal behavior of polyethylene with precisely placed amphiphilic branches are described. The amphiphilic branches contain tetraethylene glycol as the hydrophilic segment and either pyrene, n -hexyl, or n -tetradecyl moieties as the hydrophobic segment. Monomer and precursor structures have been con…
We apply the density functional technique to investigate the magnetism induced in transition metal dioxides ZrO2 and TiO2 by substitution of the cation by a vacancy or an impurity from groups 1A or 2A of the periodic table, where the impurity is either K or Ca. It is demonstrated that the vacancy and the K-impurity le…
Magnetic Langmuir−Blodgett (LB) films of bimetallic coordination nanoparticles of the Prussian blue analogue Cs 0.4 Ni[Cr(CN) 6 ] 0.9 were prepared by using the adsorption properties of a monolayer of dioctadecyldimethylammonium bromide (DODA). The molecular organization of the DODA monolayer is strongly affected by t…
Ionic thermoplastic elastomers with dicarboxylate functionalities were obtained via neutralization of high-molecular-weight hydrolyzed maleated EPM rubber (MAn- g -EPM) with potassium (K + ) and zinc (Zn 2+ ) acetate. The lower reactivity of the second of two adjacent carboxylic acid groups after neutralization of the…
Nonaphenylenes and dodecaphenylenes have been synthesized by using electron-transfer oxidation of Lipshutz cuprates with duroquinone. Oxidation of the Lipshutz cuprate derived from 4,4''-dibromo-o-terphenyl 3a in THF produced nonaphenylene 1a in 46% yield, whereas the similar oxidation of the Lipshutz cuprates derived…
A new class of multichromophoric host compounds capable of binding guest species through two-point coordinative interaction is reported. The hosts contain appended zinc porphyrin (ZnP) moieties connected covalently by acetylene linkages to a central oxoporphyrinogen (OxP) unit through its central macrocyclic nitrogen…
This work aimed to produce a new calcium alginate-Capsul edible film with antioxidant incorporated in matrix. The vitaminic stability was evaluated in the films during their storage under different conditions for 140 days. The films were characterized with respect to their mechanical properties and surface morphology.…
Two conjugated dendrimers with fluorinated terminal groups have been designed and synthesized. Dendrimer TP1 exhibits nanofibrous self-assembly ability accompanied by an unusual blue-shifted emission from nanofibers, and TP2 shows efficient electroluminescence property in single-layer organic light-emitting diodes (OL…
The crystallization rate of isotactic polypropylene (iPP) is often enhanced with sorbitol-based nucleating agents like 1,3:2,4-bis(3,4-dimethylbenzylidene)sorbitol or DMDBS. In the concentration range from the eutectic point (∼0.1 wt %) to 1 wt %, DMDBS crystallizes before the polymer, building a network of nanofibril…
Growth of zinc oxide nanorods with controlled defect densities was achieved in a low-temperature electrochemical process. The concentration of the defects was found to play an important role in the exciton emission in the ZnO nanorods, leading to shifts in the peak position and changes in the spectral shape of the ban…
Charge-transfer salts of protonated cations of 2,2′-disubstituted-4,4′-biimidazoles and oligo(imidazole)s with tetracyanoquinodimethane (TCNQ) were investigated to demonstrate the high potential of these systems for the regulation of molecular arrangement and electronic structure of charge-transfer salts. 4,4′-Biimida…
Pills are formed by entangling fibres into discrete balls on the surface of fabrics which are usually the result of wear, abrasion, washing or a combination of all three. In the present study, the effect of initial modulus of fibres on the pilling of woven fabrics was investigated. For this purpose, non-shrinkable (re…
Thermal resistance of woven fabrics can be calculated using a lumped model wherein the yarns, interlacements and air pores in a fabric can be treated as a system of resistances. Convective heat transfer can be simulated with the help of computational fluid dynamics (CFD). This paper presents an exhaustive exercise to…
