Hollow polyhedral graphite particles with 200~400 nm in diameter have been synthesized by heating oxalic acid, ferrocene and metallic magnesium at 580 C, typically forming diamond-like octahedral structure. Combined with SEM, TEM, SAED patterns, and Raman spectroscopy, it was shown that the surface of graphite polyhed…
Bacterial poly(hydroxyalkanoates) (PHAs) vary in the composition of their monomeric units. Besides saturated side-chains, unsaturated ones can also be found. The latter leads to unwanted by-products (THF ester, secondary alcohols) during acidic cleavage of the polymer backbone in the conventional analytical assays. To…
Abstract Glyoxal, in the presence of base, has been used to crosslink zein in a melt process involving reaction in a melt state combined with compression molding. The resulting zein articles had improved tensile strength, increasing from 34.3 to 40.6 MPa, when the amount of glyoxal was 6% by zein weight. Reduced solub…
The effective attenuation length (EAL) of low-energy electrons in CoO is investigated by photoemission spectroscopy experiments $(5\ensuremath{\le}h\ensuremath{\nu}\ensuremath{\le}19\phantom{\rule{0.3em}{0ex}}\mathrm{eV})$ by measuring the Ag Fermi-edge signal through a CoO overlayer of increasing thickness. The EAL i…
Abstract In this study, a series of achiral monomers and chiral monomers of different flexible spacer chains based on cholesteryl moiety were synthesized. Polymer stabilized cholesteric liquid crystal (PSCLC) cells were then created by incorporation of the polymer networks. The influence of the nature of the monomers…
Fourier syntheses providing electron density maps are usually affected by truncation effects due to the limited data resolution. A recent theoretical approach [Altomare, Cuocci, Giacovazzo, Kamel, Moliterni & Rizzi (2008). Acta Cryst. A 64 , 326–336] suggests that the resolution bias may be reduced by correcting t…
The synthesis and characterization, by optical spectroscopy, mass spectrometry, superconducting quantum interference device (SQUID) magnetometry, and single-crystal X-ray diffraction, of six iron complexes of tetraanthracenotetraazaporphyrin (TATAP) are reported. Eight benzo groups, flanking the macrocycle periphery,…
This chapter demonstrates how a model of reinforced elastomers in its state allows a thorough description of the large-strain materials behavior of reinforced rubbers in several fields of technical applications. It presents a thoroughgoing line from molecular mechanisms to industrial applications of reinforced elastom…
We demonstrated the photochemically induced nucleation of ribonuclease A (RNaseA), which lacks Trp residual groups. We have reported the photochemically induced nucleation of the hen egg-white lysozyme and the thaumatin systems, where photochemically induced nucleation brought about the photochemical reaction of the T…
The emergence of thermoplastic elastomers (TPEs) provided a new horizon to the field of polymer technology. TPEs bridge the gap between conventional rubbers and thermoplastics. The hard segments that act as physical cross-links are thermally labile, and this allows TPEs to soften and flow under shear force at elevated…
This work examined the effects of carboxyl content on the characteristics of TMP long fibers. The carboxyl groups on TMP long fibers were generated by a TEMPO-mediated oxidation using different amounts of sodium hypochlorite. In general, the increases in carboxyl content improved the tensile and burst indices but redu…
Using a laser monitoring observation technique, the solubilities of 11β-hydroxypregna-1,4,16-triene-3,20-dione in ethanol, acetone, and ethanol + water were determined by the synthetic method. The experimental data can be well correlated by the Apelblat equation (for the ethanol and acetone pure solvent system) or the…
ABSTRACT Olive oil was incorporated into whey protein through emulsification to produce films. Whey protein films were prepared by dispersing 10% protein in distilled water; and plasticized with different levels of glycerol (glycerol : protein [Gly : pro ] = 0.5 and 0.6). Olive oil was added at different levels (oil :…
Abstract In den letzten Jahren hat sich gezeigt, dass neben anorganischen Silicaten und Phosphaten auch Carboxylate, Arsenate, Sulfate, Selenate, Selenite, Germanate und Phosphite offene Gerüststrukturen bilden können. Von besonderem Interesse sind die organisch‐anorganischen Hybridverbindungen, die sich aus der Kombi…
Photoactive nanostructured micellar films were prepared from the amphiphilic copolymer poly(sodium styrenesulfonate- stat-2-vinylnaphthalene) (PSSS- stat-VN) and cationic polyelectrolyte poly(diallyldimethylammonium chloride) (PDADMAC) or poly(allylamine hydrochloride) (PAH) on quartz and silicon substrates via layer-…
Transparent and conductive indium tin oxide (ITO) films with thickness between 0.2 and 0.7 µm were deposited by sputtering at room temperature on glass and polyethylene terephthalate (PET) substrates. All films were polycrystalline, with crystallite size increasing and lattice distortion decreasing when the film thick…
The magnetic and electronic properties of multiferroic $\mathrm{Tb}\mathrm{Mn}{\mathrm{O}}_{3}$ in the paramagnetic, antiferromagnetic, sinusoidal, and spiral-spin phases were studied by spectral generalized magneto-optical ellipsometry. The measurements show a strong anisotropy of the dielectric tensor. A redistribut…
Abstract Eight poly(imide‐siloxane)s co‐polymers have been prepared by one pot solution imidization method. The polymers are synthesized by the reaction of bisphenol‐A‐dianhydride (BPADA) with fluorinated diamine 4,4′‐bis(3″‐trifluoromethyl‐ p ‐aminobiphenyl ether) biphenyl, and aminopropyl‐terminated polydimethylsilo…
Two heterometallic polymers containing cations [Cu(en)2]2+ and either the [Mn(mal)2(H2O)2]2- (1) or [Mn2(succ)2Cl2]n2n- (2) anions (mal=malonate and succ=succinate) were investigated by X-ray crystallography, high-field electron paramagnetic resonance (EPR) spectroscopy, and magnetic susceptibility measurements. Magne…
The rare-earth metal(III) oxide selenides of the formula La4O4Se[Se2], Ce4O4Se[Se2], Pr4O4Se[Se2], Nd4O4Se[Se2], and Sm4O4Se[Se2] were synthesized from a mixture of the elements with selenium dioxide as the oxygen source at 750 degrees C. Single crystal X-ray diffraction was used to determine their crystal structures.…
