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…
In this research work, an attempt has been made to impart multi-functional finish on denim fabric for value addition. The denim fabrics were treated with synthesized nano-TiO2 particle using direct exhaust, microencapsulation and nano encapsulation method. The resultant fabrics were analyzed for their change in physic…
We have investigated the structural evolution of La${}_{0.2}$Sr${}_{0.8}$MnO${}_{3}$ using temperature dependent high resolution synchrotron x-ray diffraction technique. In a wide temperature range, La${}_{0.2}$Sr${}_{0.8}$MnO${}_{3}$ reveals nanoscale structural inhomogeneity consisting of cubic and tetragonal phases…
Although the thermodynamics of metal hydrides at low to moderate temperatures has been successfully described with density functional theory (DFT) calculations using 0 K total energies and simple harmonic models, it is unclear if this approach is valid for hydrides that are stable at high temperatures. To aid developm…
Conditions for the synthesis of aluminum organophosphonate (AOP) and aluminophosphate (AlPO) spheres containing periodic mesopores were optimized and demonstrated to be general morphological controls for the surfactant-assisted synthesis of mesoporous materials. High-quality AOP and AlPO spheres with uniform mesopores…
Using europium sesquioxide nanowires as a starting material for the synthesis of europium sulfides, we have discovered alkali metal doping Eu 1– x Na x S for the first time. Alkali metal doping stabilizes the NaCl structure type of EuS at surprisingly low temperatures. We investigated the europium valence through XPS…
The low-frequency vibrational characterization of the spin-crossover complex, five-coordinate cyano(tetraphenylporphyrinato)iron(II), [Fe(TPP)(CN)](-), is reported. Nuclear resonance vibrational spectroscopy has been used to measure all low-frequency vibrations involving iron at several temperatures; this yields vibra…
Two new Zintl compounds A(10)LaCdSb(9) (A=Ca, Yb), namely, Ca(9.81(1))La(0.97(1))Cd(1.23(1))Sb(9) and Yb(9.78(1))La(0.97(1))Cd(1.24(1))Sb(9), have been designed and synthesized by applying the Zintl concept. Although both compounds are isoelectronic with their Ca(11)InSb(9) and Yb(11)InSb(9) analogues, they crystalliz…

In this work, we introduce a new perspective in explaining the origin of magnetism in dilute magnetic semiconductors, carbon-based materials and other related materials. According to our proposal, the magnetism in these materials is the result of the synergistic action of defect-induced electronic processes mostly of…
We have studied the electronic and magnetic states of Mn and Co atoms at the Co${}_{2}$Mn${}_{\ensuremath{\beta}}$Ge${}_{0}.38$ (CMG)/MgO ($\ensuremath{\beta}=0.67$--1.8) interfaces, which constitute CMG/MgO/CMG magnetic tunnel junctions, by means of x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dich…
