Abstract Reactive compatibilization of recycled low- or high-density polyethylenes (LDPE and HDPE, respectively) and ground tire rubber (GTR) via chemical interactions of pre-functionalized components in their blend interface has been carried out. Polyethylene component was functionalized with maleic anhydride (MAH);…
In this paper, we use a thermodynamic model based on superposition of bistable contributions to describe the magnetization curve of materials with a magneto-structural phase transformation. In order to describe the decreasing coercivity with increasing temperature, we extend the model to temperature-dependent distribu…
We report the synthesis and characterization of Fe-FeOxcore-shell nanowires by thermal conversion of the Fe nanowires from pulse electrodeposition in anodized aluminum oxide (AAO) nanotemplates under various conditions. Well-defined core-shell nanostructure of the Fe-FeOxnanowires was confirmed by TEM and correspondin…
The novel electronic properties of graphene, including a linear energy dispersion relation and purely two-dimensional structure, have led to intense research into possible applications of this material in nanoscale devices. In this paper, we review the unique electronic properties of graphene that give it the potentia…
Magnetic, micromagnetic, and texture properties of the martensitic thin films prepared by magnetron sputtering of Ni$_{49.5}$Mn$_{28}$Ga$_{22.5 }$target on MgO(100) wafer are studied as a function of film thickness. The films exhibit 220-fiber texture. Moreover, in contrast to thick films, a considerable in-plane text…
The structural change of La 9.33−2 x (SiO 4 ) 6 O 2−3 x with increasing x value was investigated by means of laboratory X‐ray powder diffraction (Cu K α 1 ). Crystal structures of the three types of specimens with x =0, 0.06, and 0.085 were refined by the Rietveld method, with the anisotropic displacement ( U ) parame…
The adsorption of carbon monoxide on a clean and hydroxylated rutile (110) surface has been investigated using a periodic approach at DFT/B3LYP level. The hydroxylated surface was modelled by considering both terminal and bridging OH groups. The variation of the electrophilicity of the Lewis acid site near these group…
Abstract Summary: Two peptides (FEFEFKFK and HHHHHHFEFEFKFK) have been synthesised and their phase diagrams mapped out as a function of concentration and temperature. Both peptides formed self‐supporting fibrillar hydrogels above a similar critical molar gelation concentration with a fibril diameter corresponding to t…
Abstract Summary: In this study, maleic anhydride (MA), and citric acid (CA) used as the processing additive and plasma treatment to improve the processing ability and mechanical strength of biodegradable starch/poly (vinyl alcohol) (PVA) blends were studied. The melt flow index (MFI) of starch/ glycerol/PVA (300g/60g…
Self‐assembling in a linear supramolecular liquid crystalline (LC) polymer based on 4,4′‐bipyridine and bis‐(4‐carboxyphenyloxycarbonyl)‐heptanoate was studied by IR spectroscopy and optical microscopy. Although just a simple single hydrogen bond is required for the formation of a polymer chain, the reversibility of t…
Abstract Summary: Stereorregular polylactides such as poly (L‐lactide) (PLLA) or poly (D‐lactide) result from polymerization of optically pure lactides and are semicrystalline. Optically non‐active poly(D,L‐lactide) (PDLLA) can be regarded as random or atactic copolymers, show a random moiety distribution, and are com…
Diamondlike carbon (DLC) deposited by focused-ion-beam chemical vapor deposition (FIB-CVD) has the interesting material characteristics because DLC deposited by FIB-CVD using the gallium (Ga) FIB contained Ga. The DLC wires were subjected to annealing, and it was found that their resistivity and the Ga content of DLC…
We discuss the solution of the inverse problem in scatterometry i.e. the determination of periodic surface structures from light diffraction patterns. With decreasing details of lithography masks, increasing demands on metrology techniques arise. By scatterometry as a non-imaging indirect optical method critical dimen…

Abstract X-ray diffraction peak profiles obtained from 18Ni lath martensite were analyzed in accordance with the modified Williamson – Hall and modified Warren – Averbach methodologies, aided by supplemental optical and transmission electron microscopy. After instrumental broadening removal, structural peak broadening…
This paper presents the production method and the compressive mechanical response at low strains for a collection of polyethylene foams with high densities and cell sizes in the microcellular range. The materials were produced using an improved compression moulding technique that allows and independent control of dens…
Stress free heteroepitaxial thin films of PZT-based ternary perovskite, xPb(Mn,Nb)O3-(1-x)PZT, were fabricated by magnetron sputtering on (001)MgO substrates and evaluated their crystal structure, ferroelectric and piezoelectric properties. The heteroepitaxial thin films showed single c-domain /single crystal structur…
The electrical and mechanical properties of as- grown and also hydrogen and nitrogen incorporated tetrahedral amorphous carbon (ta-C) films, deposited using S bend filtered cathodic vacuum arc process have been reported. First, the effect of varying negative substrate bias on the dark conductivity (σ D ), activation e…
Here, the authors studied the directed assembly of the asymmetric ternary blends, composed of polystyrene-block-poly(methyl methacrylate) copolymer (PS-b-PMMA) and the corresponding PS and PMMA homopolymers, on a checkerboard chemical pattern which was fabricated by e-beam lithography, controlling the periodicity (LS)…
Contamination flashover is a major concern affecting the reliability of power systems. Industries switched over from porcelain to polymers due to lighter weight and superior contamination performance. Polymers especially silicone rubbers (SR) helped considerably to eliminate the contamination problem. Bio contaminatio…
