Abstract 1,5‐Pentanediol dibenzoate (PDDB) was evaluated as a potential “green” plasticizer for poly(vinyl chloride) (PVC) at concentrations ranging between 20 and 80 parts by weight per hundred parts of resin. The results of glass transition temperature ( T g ) and tensile tests of PDDB blends with PVC were compared…
Abstract The copper(II) open cubane 1 has been synthesized and its structure determined. It is insoluble in water and efficiently catalyzes the Henry reaction with high yield. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
A new class of integrative radial crystals (Krause et al 2006 Phys. Rev. Lett. 96 165502) and radial superlattices (RSLs) (Deneke et al 2004 Appl. Phys. Lett. 84 4475) has been realized by the roll-up of semiconductor-based hybrid layer systems on a substrate surface (Prinz et al 2000 Physica E 6 828, Schmidt and Eber…
Abstract Several parameters, such as crosslinking agent concentration, blowing agent concentration, and temperature, were varied to evaluate their effects on the structure and mechanical properties of low‐density polyethylene (LDPE) foams. Dicumyl peroxide (DCP) was used as crosslinking agent, while azodicarbonamide (…
Gold nanoparticles of various sizes, supported onto ceria, were synthesized using both deposition−precipitation and coprecipitation methods. Whatever the size, the study of the Au/CeO 2 interface confirms the existence of two preferential orientation relationships with a dislocation network which compensates the 25% i…
Starting from the full many-body Hamiltonian of interacting electrons the effective self-energy acting on electrons residing in a subspace of the full Hilbert space is derived. This subspace may correspond to, for example, partially filled narrow bands, which often characterize strongly correlated materials. The forma…
Shape memory polymer is an important area of interest in the polymer science research because of its many applications in industry such as biomedical, smart textiles, actuations and so on. Among the shape memory polymers, temperature responsive shape memory polymers are gaining much attention to the scientist as their…
High quality SrTiO 3 thin film on (1 1 0) DyScO 3 substrate is grown by laser molecular beam epitaxy. The lattice strain resulting from the lattice mismatch between the substrate and the film relaxes gradually with depth. A critical thickness of about 30 nm for sharp strain relaxation is observed. The dislocation dens…
The solid-state structure of mercury oxide and its low-pressure modifications are known to significantly differ from those found for the corresponding zinc and cadmium compounds, that is, one changes from a simple hexagonal wurtzite or cubic rock salt structure found in zinc oxide and cadmium oxide to unusual chainlik…
We present ultrafast microscopy measurements on CdSSe semiconductor nanobelts addressing the early luminescence dynamics, charge transport, and charge carrier localization in individual nanoparticles. The diffraction limited spatial resolution of our femtosecond Kerr-gated microscope allowed us to address single parti…
Rather uncommon but pronounced odd-even effects in the clearing temperatures of liquid crystals are found for three new homologous series of discotic tetraphenylenes [figure: see text]. Detailed similarities to the well-known odd-even effects in calmitic mesogens point towards a more general understanding of odd-even…
In this Brief Report, we use density functional theory to predict the existence of a heretofore unobserved crystalline compound, BaCl, and additionally predict it to be isostructural with NaCl (rocksalt). Due to the chemistry of Ba, which strongly prefers a $2+$ charge state, compounds where Ba nominally exhibits a $+…
Carrying out information about the microstructure and stress behaviour of ferromagnetic steels, magnetic Barkhausen noise (MBN) has been used as a basis for effective non-destructive testing methods, opening new areas in industrial applications. One of the factors that determines the quality and reliability of the MBN…
Inhibitive and adsorption properties of ethanol extract of Colocasia esculenta for the corrosion of mild steel in H2SO4 were investigated using weight loss, hydrogen evolution and IR methods of monitoring corrosion. The results obtained indicates that ethanol extract of C. esculenta is a good inhibitor for the corrosi…
The gelation and photophysical properties of mono- and bis-cholesterol derivatives linked to diphenylbutadiene have been investigated. Scanning electron microscopy of xerogels of the monocholesterol derivatives indicated that these molecules self-assemble into 3D networks consisting of helically twisted fibers. In con…
We investigate the dependence of the nonlinear optical properties of Cu-doped and Ag-doped As(2)Se(3) glasses on the incident pulse-width at 1.064 microm using the Z-scan technique. In this work, 11.5-ns optical pulses from a Nd:YAG laser were compressed up to 1.6 ns by using stimulated Brillouin scattering in heavy f…
Hybrid films composed of chitosan and Keplerate-type polyoxometalate, {Mo72Fe30} (Mo72VIFe30IIIO252L102.ca.180H2O, L=H2O/CH3COO-/Mo2O8/9n-), were fabricated on quartz, silicon, and ITO substrates by layer-by-layer (LbL) method. The LbL films were characterized by UV-vis spectroscopy, X-ray photoelectron spectroscopy (…
Protein-resistant poly(poly(ethylene glycol)monomethacrylate)-graft-Si(100), or Si-g-P(PEGMA) hybrids, were prepared via surface-initiated atom transfer radical polymerization (ATRP) of the poly(ethylene glycol)monomethacrylate (PEGMA) macromonomer from the hydrogen-terminated Si(100) surface (Si-H surface). The resul…
Titania−silica mixed oxides (denoted as TiO 2 −SiO 2 ) with different Ti contents are prepared by a sol−gel route in the presence of citric acid (CA). Various characterization techniques, including XRD, FT-IR, N 2 -adsorption, TEM, solid-state CP-MAS NMR spectroscopy, UV−vis, and NH 3 -TPD, have been carried out to in…
Our works shows that the americium pyrochlore (241)Am(2)Zr(2)O(7) undergoes a phase transition to a defect-fluorite structure along with an unusual volume contraction when subjected to internal radiation from alpha-emitting actinides. Disorder relaxation proceeds through the simultaneous formation of cation antisites…
