Hybrid nanoparticles (NPs) composed of multiple components offer new opportunities for next-generation materials. In this study, a paradigm for the noble metal/ternary complex oxide hybrid NPs is reported by adopting pulsed laser ablation in liquids. As model hybrids, gold-spinel heterodimer (Au-CoFe2O4) and gold-perv…
The magnetic modulation of the surface plasmon-polariton (SPP) wavevector is experimentally and theoretically studied for the plasmonic modes excited in metal-insulator-metal (MIM) magnetoplasmonic cavities. For this purpose, Ag/SiO₂/Ag multilayers with different SiO₂ layer thickness in which a thin Co layer is positi…
In this work, we focus on the study of the structural and elastic properties of mercury digallium selenide (HgGa2Se4) which belongs to the family of AB2X4 ordered-vacancy compounds with tetragonal defect chalcopyrite structure. We have carried out high-pressure x-ray diffraction measurements up to 13.2 GPa. Our measur…
We evaluate whether lattice or internal phonons dominate the thermal excitation of the N-N bonds in α-cyclotrimethylene trinitramine (α-RDX) by computing the fractional contributions of phonon modes to the excitation of all atomic interactions. We derive a method to compute these contributions, which we call mode ener…
Collagen-based biomaterials suffer from poor mechanical properties and rapid degradation. Elastin-like polypeptides (ELPs) possess good biocompatibility and have unique solution properties that allow them to coacervate above a critical temperature. The objective of this research was to prepare a series of freeze dried…
The crystal structures of anhydrous enrofloxacin (EFC) ( 1 ), enrofloxacin hexahydrate (EFC·6H 2 O) ( 2 ), enrofloxacin maleate (EFC-M) ( 3 ), enrofloxacin hemifumarate (EFC-F) ( 4 ), enrofloxacin hemisuccinate (EFC-S) ( 5 ), enrofloxacin hemioxalate (EFC-O) ( 6 ), enrofloxacin acetate (EFC-A) ( 7 ) and ammonium salt…
We present a detailed analysis of the time decay of magnetization (M) and ac-magnetic susceptibility (χac)of hexagonal-shaped MnCo2O4nanocrystals of average size 28 nm. The temperature (T) and magnetic field (H) dependence of the magnetization measurements reveal that even in the ferromagnetic state these nanocrystals…
The double photoionization of Mg has been studied experimentally and theoretically in a kinematic where the two photoelectrons equally share the excess energy. The observation of a symmetrized gerade amplitude, which strongly deviates from the Gaussian ansatz, is explained by a two-electron interference predicted theo…
Abstract In this study, the relative rate of polymerization of acrylic acid (AA) versus methacrylic acid (MAA) and the effect of water on the polymerization kinetics are investigated within a combined static and molecular dynamics set of computational tools. Experimentally the relative rate of propagation of AA versus…
4′,4″(5″)-Di- tert -butyldibenzo-18-crown-6 (DTBB18C6) was synthesized using 4- tert -butyl catechol (TBC) as starting material, 2,2′-diethylene glycol di( p -touenesulfonate) as cyclization reagent, Cs 2 CO 3 as template, and tetrahydrofuran (THF) as solvent. The reaction was carried out in a sealed environment with…
The effective thermoelastic properties of a fuzzy fiber-reinforced composite (FFRC) have been estimated by employing the generalized method of cells approach and the Mori–Tanaka method. The novel constructional feature of this fuzzy fiber-reinforced composite is that the uniformly aligned carbon nanotubes (CNTs) are r…
The OH/OD isotopic shift factors ( i = ν OH /ν OD ) of isolated silanols on SiO 2 and [Si]BEA are between 1.3563 and 1.3568, values lower than the theoretical shift of 1.3744. However, i of the harmonic OH modes almost coincides with the theoretical value which indicates that the experimental deviations in this case a…
We systematically investigate how the range of interaction between non-bonded monomers influences the formation of structural phases of elastic, flexible polymers. Massively parallel replica-exchange simulations of a generic, coarse-grained model, performed partly on graphics processing units and in multiple-gaussian…
The reduced graphene/poly(vinylidene fluoride) nanocomposite films were prepared by the solution casting-thermal reduction process using graphene oxide and poly(vinylidene fluoride) resin. The results show that with the presence of reduced graphene nano sheets in the nanocomposite, the structure of poly(vinylidene flu…
This paper presents a novel compensation technology of static synchronous compensator integrated with distribution transformer (DT-STATCOM). STATCOM is connected with the transformer taps at the high-voltage (HV) windings. By selecting the appropriate tap voltage level, it can help to make full use of the spare capaci…
Methyl bromide is used as feed in a process that converts it to gasoline. It is prepared by the gas-phase reaction of CH 4 with Br 2, a reaction that produces, besides the desired CH 3 Br, large amounts of CH 2 Br 2 . The latter cokes the catalyst used for gasoline production. The separation of CH 2 Br 2 by distillati…
Ferromagnetic resonance (FMR) and magnetic studies have been carried out on polycrystalline YIG films deposited by pulsed laser deposition (at TS:750 °C, O2:5×10-2mbar) using a range of laser energies (240 to 350 mJ). The films were ex situ annealed (Ta:700 °C, in air for 2 h). The film thickness increases from 100 to…
By use of a quartz crystal microbalance with dissipation (QCM-D), we have investigated the specific ion effect on the growth of poly(sodium 2-acrylamido-2-methylpropanesulfonate)/poly(diallyldimethylammonium chloride) multilayer at a salt concentration as low as 2.0 mM in water-methanol mixtures. QCM-D results demonst…
In higher plants, cellulose is synthesized by cellulose synthase complexes, which contain multiple isoforms of cellulose synthases (CESAs). Among the total 10 CESA genes in Arabidopsis, recessive mutations at three of them cause the collapse of mature xylem cells in inflorescence stems of Arabidopsis (irx1(cesa8), irx…
Legierte, monodisperse AgPd-Nanopartikel von 2.2 nm Größe erweisen sich als hochaktive und langlebige Katalysatoren für die Dehydrierung von Ameisensäure. Die Studie demonstriert, wie Legierungseffekte die katalytische Wirkung der Nanopartikel bei der Wasserstofferzeugung aus Ameisensäure steigern (siehe Bild).
