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.…
We demonstrate a facile method for the preparation of the Pd nanobricks (NBs) which comprise atomic-step defects on the nanocrystal surface. By simply controlling the reaction parameters including the cetyltrimethylammonium bromide (CTAB) to hexamethylenetetramine (HMT) ratio and the ascorbic acid concentration, we ca…
Gold nanorods are deposited on the core surface of an etched optical fiber, and their surface plasmon resonance is excited by the evanescent wave from the optical fiber. The excitation of the surface plasmon produces strong light scattering from individual nanorods, allowing for single-particle scattering-based imagin…
Window glass is a ternary mixture, while Pyrex (after window glass, the most common form of commercial glass) is a quaternary. Here, we investigate the chemical, physical, and mathematical factors that determine the compositions of these optimized glasses. Previously, we succeeded in deriving exactly the composition o…
Angle-dispersive high-pressure powder X-ray diffraction, high-pressure Raman, and ab initio density functional theoretical (DFT) calculations were performed on KBH 4 up to 20 GPa. We demonstrate that KBH 4 exhibits structural phase transitions from the ambient α-KBH 4 phase (cubic F m 3̅ m ) to β-KBH 4 (tetragonal P 4…
Summary Root exudates help drive the formation of the rhizosphere by binding soil particles, but the underlying physical mechanisms have not been quantified. This was addressed by measuring the impact of a major component of root exudates, polygalacturonic acid (PGA), on the interparticle bond energy and fracture toug…
