The methyltrioxorhenium (MTO)/pyrazole-mediated H(2)O(2) oxidation of octaethylporphyrin and a number of meso-tetraarylporphyrins offers simple and good yielding access to the corresponding N-oxides, only few of which were prepared before. The crystal structure of a free base tetraarylporphyrin N-oxide demonstrates th…
The perovskite "PbCrO(3)" was synthesized at high pressure and high temperature. Its magnetic properties have been investigated by means of magnetization, specific heat, and resistivity measurements. Earlier workers had concluded it to have a G-type antiferromagnetic structure. However, our measurements suggest a rath…
Abstract Uncompatibilized and compatibilized (polypropylene grafted maleic anhydride as compatibilizer) polyethylene terephthalate (PET)/polypropylene (PP)/TiO 2 microfibrillar composites (MFC) were prepared by injection molding of the pelletized PET/PP/TiO 2 drawn strands. The morphology of PET fibrils and the distri…
One-dimensional TiO 2: x Sm 3+ microfibers and microbelts were prepared by electrospinning. X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectrometer (EDS), high-resolution transmission electron microscopy (HRTEM), photoluminescence (PL), electron paramagnetic resonance (EPR), a…
High pressure superconductivity in iron-based superconductor FeSe(0.5)Te(0.5) has been studied up to 15 GPa and 10 K using an eight probe designer diamond anvil in a diamond anvil cell device. Four probe electrical resistance measurements show the onset of superconductivity (T(c)) at 14 K at ambient pressure with T(c)…
The new borate phosphor CaB(2)O(4):Eu(3+) was synthesized by solid-state method and their photoluminescence properties were investigated. The results show that the pure phase of CaB(2)O(4) could be available at 900 degrees C, CaB(2)O(4):Eu(3+) phosphor could be effectively excited by the near ultraviolet light (NUV) (…
Abstract Cholesterin an der Kette : Der Cholesterinaustausch ist einer der Hauptgründe für die Unbeständigkeit von Liposomen im Blut. Durch Bildung eines kovalent verbundenen Cholesterin‐Glycerophosphocholin‐Hybrids bleibt der stabilisierende Effekt des freien Cholesterins erhalten, sein Austritt aus der Doppelschicht…
We report a facile, high yield synthesis and characterization of discrete, ternary porphyrin-metal-polyoxometalate (Por-M-POM) complexes where a group (IV) transition metal ion is bound both to the porphyrin core and to the lacunary site of a Keggin POM, PW(11)O(39) (-7). The remarkably robust complexes exploit the fa…
We investigated the adsorption and reactions of propane on a PdO(101) thin film under ultrahigh vacuum conditions and find that C−H bond cleavage of propane is highly facile on this PdO surface. At 85 K, propane adsorption on the PdO film produces two distinct states that desorb at temperatures of 120 and 190 K during…
The use of magnesiothermic reduction and CVD to obtain Si spheres is reported. The porous structures of the Si spheres after the former process and the infilling of their pores after the latter one are observed. The optical properties of opals formed with these spheres are used to assess the power of the method and th…
We employ time reversal for deep subwavelength focusing in plasmonic periodic nanostructures. The strong anisotropy enables propagating modes with very large transverse wave vector and moderate propagation constant, facilitating transformation of diffraction-limited plane waves to high-$K$ Bloch waves in the plasmonic…
We report a method to fabricate functional oxide nanostructures ordered over the centimeter scale. Self-assembly of SrTiO 3 (001) chemical terminations through appropriate thermal processing leads to large-area chemical nanopattering of the surface. Such nanopatterned surfaces, stable at relatively high temperature, c…
Structural studies of substituted 1,3,5-benzenetrisamides, a new family of highly versatile and efficient nucleating and clarifying agents for polymeric materials, are reported. Subtle details of the molecular structure of these species are shown to have a major influence on their solid-state order, morphology, and ab…
Atomization energies at 0 K and heats of formation at 0 and 298 K are predicted for (CH3)H2N-BH3, (CH3)HN=BH2, (BH3)HN=CH2, (CH3)H2B-NH3, (CH3)HB=NH2, and (NH3)HB=CH2, as well as various molecules involved in the different bond-breaking processes, from coupled cluster theory (CCSD(T)) calculations. In order to achieve…
Magnetically separable hydrogenation catalysts serve as an example of a multifunctional M13 bacteriophage nanocomposite made by (a) growing Rh nanoparticles lengthwise along the pVIII region via nonspecific electrostatic interactions and (b) anchoring Fe3O4 nanoparticles on the pIII tip via materials-specific interact…
The dense ceramic oxygen separation membrane holds promise to reduce the oxygen production cost significantly over the current mature cryogenic distillation process. Preparation of membranes in hollow fiber geometry is expected to lead to a remarkable increase in the oxygen production capacity of the membrane unit. Ga…
We report the observation of large exchange bias (EB) in Ni 50− x Co x Mn 38 Sb 12 Heusler alloys with x = 0, 2, 3, 4, 5, which is attributed to the coexistence of ferromagnetic (FM) and antiferromagnetic (AFM) phases in the martensitic phase. The phase coexistence is possibly due to the supercooling of the high tempe…
A lithium salt of anionic scandium tetraborohydride complex, LiSc(BH 4 ) 4, was studied both experimentally and theoretically as a potential hydrogen storage medium. Ball milling mixtures of LiBH 4 and ScCl 3 produced LiCl and a unique crystalline hydride, which has been unequivocally identified via multinuclear solid…
Monodisperse colloidal CdSe nanocrystals (NCs) with different sizes were synthesized, and the time-resolved photoluminescence (PL) spectra were measured to explore the evolution of surface states during the NC’s growth. The PL quantum yield, fluorescence lifetime, and the surface-related emission had the identical siz…
