Valence alternation pair (VAP) states are formed by a closed-shell combination of two space- and charge-separated topological defect centres. These pairs of defects, although historically invoked to explain the electronic properties of bulk inorganic glassy materials (e.g., amorphous silicon dioxide) via the concept o…
A series of polypropylene (PP)/poly (butyl methacrylate-co-hydroxyethyl methacrylate) (PBMA-co-HEMA) blend fibers were prepared by the melt-spinning method. The surface properties of the oil absorptive fibers were investigated for the first time by contact angle measurement in various liquids. The results indicate tha…
The title molecule 1,5-diphenylpenta-2,4-dien-1-one (cinnamylideneacetophenone, CA) has been synthesised and characterised by FTIR, FT-Raman, NMR and UV–vis spectral analyses. The possible stable conformers of the CA molecule were searched by potential energy surface scan at B3LYP level of theory. The molecular geomet…
New generation Synchrotron Radiation (SR) sources and Free Electron Lasers (FEL) require novel concepts of beam diagnostics to keep photon beams under surveillance, asking for simultaneous position and intensity monitoring. To deal with high power load and short time pulses provided by these sources, novel materials a…
In this study electrically conductive polyester fabrics were prepared by using conductive polyaniline polymer. The conductive fabrics were prepared by in-situ chemical oxidative polymerization of aniline using ammonium persulphate as the oxidant by a process of diffusion polymerization in a mixed bath. These fabrics w…
UNLABELLED: The use of surfactants during soil washing process can create massive foam, which has a negative impact on the effective use of equipment. A series of tests was conducted to evaluate the defoaming performance of three defoamers and to investigate the influence on removal of polycyclic aromatic hydrocarbons…
In the present study, the esterification of Cannabis indica fiber was carried out with benzoyl chloride.The raw as well as the esterified Cannabis indica fibers (with 10, 20, 30, and 40% particle loading) were subsequently used as reinforcement to prepare polyester matrix–based composites. The characterization of este…
A hydrophilic cyclic tetra-β-peptide having guanine at the side chain (CPG) was synthesized to construct a four-peptide-nanotube bundle with the formation of guanine quadruplex (G-quartet). CPG was so soluble in water that molecular association of CPG was very limited in water. However, in the presence of potassium io…
The self-assembly of CdSe quantum dots (QDs) onto a patterned silica surface generated from surface microcontact click printing is presented. The mechanically robust self-assembly process produces patterns of QDs which remain steadfast, even as subsequent reactions are performed on the substrate, demonstrating the uti…
Abstract The aim of this study was to investigate the influence of lang fibre concentration on Ioadability and pulp properties during LC refming of mechanical pulp. Lang fibre concentration was adjusted to three different Ievels by screen fractionation of the pulp. The three pulps were refined in a single disc pilot s…
Abstract The role of the covalent connections of iron(II) spin‐crossover centres in the transmission of perturbation produced by the HS ↔ LS transition has been investigated for the new 3D coordination polymer {[Fe(qbtr) 3 ](ClO 4 ) 2 } ∞ [qbtr = 1,5‐di(1,2,3‐triazol‐1‐yl)pentane]. In this complex, a sequence of struc…
A method for automatically aligning consecutive data sets of large, two-dimensional multi-tile electron backscatter diffraction (EBSD) scans with high accuracy was developed. The method involved first locating grain and phase boundaries within search regions containing overlapping data in adjacent scan tiles, and subs…
Analysis of dynamic elastic behaviour is an objective evaluation of the stretch and recovery behaviour of the elastic fabrics or tight fit garments. The analysis of this dynamics will help to reengineer new products for improving the stamina, speed and power of the sportsmen, as one particular type of garment doesn’t…
Abstract This work explores the foam development process under atmospheric pressure as applicable to rotational molding, investigating the influence of the processing parameters, and characterizing the morphology of the foamed structure. Detailed understanding of the bubble transformation during foaming of nonpressuri…

Zinc vanadium oxide Zn 3 (VO 4 ) 2 has been prepared by means of DC magnetron sputtering and subsequent post heat treatment. The samples were synthesized via two routes: dual-target co-sputtering of ZnO and V 2 O 5 or the ordinal deposition of V 2 O 5 and ZnO thin layers. The obtained precursors were then annealed in…
Abstract A novel fractionation method was developed to characterize nanocellulose in terms of particle size. The fractionation device ues screens or membranes with known size. The scale is in the range of micro to nano, so that NFCs can be size- or shapefractionated accordingly. The procedure is somewhat analogaus to…
In this work agro-based waste natural tamarind fibers were extracted from ripened fruit, and alkali treatment and polycarbonate coating were used to improve the properties of the chemically modified fibers. The tensile properties of these chemically modified fibers were found to be improved by polymer coating. Scannin…
Abstract The columnar to equiaxed transition (CET) provides a challenging simulation goal for computational models of alloy solidification, in addition to being an important technological feature of many casting processes. CET thus provides an industrially relevant test‐case for those developing numerical models acros…
The effect of iron addition in the treated solution on the decomposition of indigo carmine is reported. The effect of iron addition was evaluated for various$\hbox{Fe}^{2+}$concentrations ranging from 0 to 118$\mu\hbox{mol/L}\ (\mu\hbox{M})$. The decolorization rate and efficiency with$\hbox{Fe}^{2+}$addition were hig…
