Biodegradable soy protein isolate (SPI), containing 2,2-diphenyl-2-hydroxyethanoic acid, films (SB) were successfully prepared with bis-(2-hydroxyethyl)sulfide as a plasticizer by compression molding at 155 degrees C and 15 MPa. By immersing the SB in distilled water for 26 h, we prepared the films (coded as SB-WM) ha…
Bifunctional catalysts containing 0.1−0.5 wt % nickel and 0.1 wt % palladium supported on HY zeolite were prepared through incipient wetness impregnation (IWI) and characterized by X-ray diffraction (XRD), Brunauer−Emmett−Teller (BET) surface area, temperature-programmed desorption of ammonia (NH 3 -TPD), temperature-…
Fully conjugated dendrimers are interesting materials as active chromophores for a range of optoelectronic applications. The rigid and well-defined framework of these materials enables structure-property relationships to be more easily understood. In this paper, we summarize the main strategies for the synthesis of po…
Biodegradable and biocompatible polymers that are engineered to nanostructures play a key role in providing solution for sustained chemotherapy. This study is focused on preparation, drug encapsulation efficiency, in-vitro drug release, in-vitro cellular uptake and cell viability of poly(caprolactone) grafted dextran…
An attempt has been made to develop fly ash filled polymer matrix composites with high damping behavior. Fly ash filled polymer matrix composites do not show very high damping property and this limits their application in many fields. Hence, unsaturated polyester resin (UPE) was blended with SBR latex in three proport…
We present time-dependent behavior of the transport and magnetic properties in electron-doped manganites. The relaxation of the electrical resistivity $(\ensuremath{\rho})$ shows a clear correlation with the microscopic properties of the samples observed through transmission electron microscopy. Two different relaxati…
Abstract One‐step in situ oxidations of 2,9‐dimethyl‐1,10‐phenanthroline to 9‐methyl‐1,10‐phenanthroline‐2‐carboxylic acid and 1,10‐phenanthroline‐2,9‐dicarboxylic acid were carried out by utilizing HNO 3 as the oxidant in the presence of Cu II , Ni II , and Cu II –Ln III salts under hydrothermal conditions, showing t…
The possibilities of effective solutions of relevant technological problems are considered based on the analysis of fundamental physical aspects, elucidation of the micromechanisms and interrelations of aging and hydrogen embrittlement of materials in the hydrogen industry and gas-main industries. The adverse effects…
The unsaturated polyester-based hybrid composites were developed by combining the kapok and glass fabrics into polyester matrix. This study describes the flexural, compressive, and interlaminar shear resistance properties of kapok/glass polyester composites with and without alkali treatment of fabrics. These propertie…
Radikal mild: Der erste bei Raumtemperatur isolierbare, strukturell charakterisierte Superoxonickel(II)-Komplex 1 mit quadratisch-planarem, vierfach koordiniertem NiII-Zentrum ist zu milden Sauerstoffübertragungen über das postulierte Intermediat 2 in der Lage, das unter H-Abstraktion zum homovalenten Komplex 3 mit ei…
Layered assemblies of single crystal gold nanoplates are directly synthesized in large scale by simply adding aniline to HAuCl 4 −HCl aqueous solution at room temperature, without the need of extra capping agent or surfactant. In this approach, the large amount of Cl −, the oxidative etching by the O 2 /Cl − pair, the…
Magnetic measurements of ${\text{La}}_{0.7}{\text{Ca}}_{0.3}{\text{MnO}}_{3}$ reveal a departure from Curie-Weiss behavior below the orthorhombic (O) to rhombohedral (R) structural transition at ${T}_{O\ensuremath{-}R}=705\text{ }\text{K}$. Between ${T}_{O\ensuremath{-}R}$ and ${T}^{\ensuremath{\ast}}=273\text{ }\text…
Plasmas generated at atmospheric pressure are used to functionalize the surfaces of polymers by creating new surface-resident chemical groups. The polymers used in textiles and biomedical applications often have non-planar surfaces whose functionalization requires penetration of plasma generated species into sometimes…
Binuclear complex [Cp* 2 Ir 2 (μ-CA)Cl 2 ] ( 2 ) (CA = chloranilate) was obtained by the reaction of [Cp*IrCl 2 ] 2 ( 1 ) with H 2 CA in the presence of base. Treatment of 2 with pyridine or 4-(4-bromophenyl)pyridine in the presence of AgOTf (OTf = CF 3 SO 3 ) in CH 3 OH gave the corresponding binuclear complexes [Cp*…
Morphological, textural, and surface properties of several Pt−Ba/Al 2 O 3 NO x storage reduction (NSR) catalysts at different Ba loading in the range 0−30 wt % were characterized by means of X-ray diffraction, high-resolution transmission electron microscopy, and Fourier-tranform infrared (FT-IR) spectroscopy using CO…
We report on depolarized light scattering spectra from suspensions of gold nanorods in terms of the depolarized ratio Ivh/Ivv measured from 400 to 900 nm. For separated, highly monodisperse and highly monomorphic samples, we observed spectra with an unprecedented depolarization ratio with a resonance maximum of about…
We present ab initio calculations for atomic oxygen adsorption on Ir(111) for a wide range of oxygen coverages, $\ensuremath{\Theta}$, namely from 0.11 to 2.0 monolayers (ML), including subsurface adsorption and thin surface-oxide-like structures. For on-surface adsorption, oxygen prefers the fcc-hollow site for all c…
The growth mechanism of Si-faceted dendrite was studied using an in situ observational technique. We directly observed the growth processes of Si-faceted dendrites from Si melts. It is found that triangular corners with an angle of 60 degrees are formed at the dendrite tip. We present an original growth model for face…
Hessian cloth (jute fiber)-reinforced polypropylene (PP) composites were prepared by compression molding. The fiber content in the composites was about 50%. The resulting composites and also PP sheets were irradiated under gamma radiation of various total doses (250—1000 krad) at the rate of 600 krad/h. It was found t…
A convenient synthetic route based on the concept of nanoreactors using the versatility of the miniemulsion technique to synthesize glutardialdehyde cross-linked gelatin nanoparticles with tailored properties is reported. It is demonstrated that, independent of the molecular weight distribution of the gelatin used, st…
