The liquid−solid mass transfer rate is studied for two three-phase reactor configurations, a stirred reactor and a rotating solid foam reactor, using the dissolution of copper by potassium dichromate as a model reaction. For the stirred reactor consisting of a Rushton stirrer and a slurry with small particles, the par…
A series of MnNi 1− x Co x Ge 1.05 ( x = 0, 0.03, 0.05, 0.07, 0.09, and 0.11) alloys were prepared by the arc-melting method. With increasing content of Co, a first-order magnetostructural transformation between the antiferromagnetic TiNiSi-type phase and the ferromagnetic Ni 2 In-type phase was observed. A magnetic a…
We report the formation of core-shell diamond particles for solid-phase extraction (SPE) and high-performance liquid chromatography (HPLC) made by layer-by-layer (LbL) deposition. Their synthesis begins with the amine functionalization of microdiamond by its immersion in an aqueous solution of a primary amine-containi…
In this paper, we demonstrate through experiments and analysis that the most probable mechanism for the observed ferromagnetism in 2% Mn-doped ZnO thin films is a combination of intrinsic and carrier-mediated interaction of the magnetic moments. While no impurity-phase contributions were detected, a strong correlation…
One-dimensional Mn 1− x Ce x O 2± y nanorod catalysts were synthesized and characterized by X-ray diffraction (XRD) and operando Raman spectroscopy to determine the active phase during methane combustion. Thermal- and reaction-induced phase-transformation determined by operando Raman indicated that the MnO x domain in…
We investigate the effect of Hartree-Fock range-separation on the calculation of magnetic exchange couplings in a set of nine bimetallic transition-metal complexes containing 3d elements (V, Cr, Mn, and Cu). To this end, we have compared magnetic exchange couplings calculated as self-consistent energy differences usin…
Zinc oxide (ZnO) is a wide band-gap material with excellent optical properties for optoelectronics applications. However, device fabrication has been hampered by difficulties in obtaining a stable p-type doping. Here, we present the first report on the growth and doping of ZnO film through the incorporation of potassi…
We use neutron scattering to study magnetic excitations in crystals near the ideal superconducting composition of FeTe(0.5)Se(0.5). Two types of excitations are found, a resonance at (0.5,0.5,0) and incommensurate fluctuations on either side of this position. We show that the two sets of magnetic excitations behave di…
We have compared the desorption characteristics of O(2), D(2), and H(2)O from the Pt(533) surface to the Pt(553) surface using temperature programmed desorption. Both surfaces consist of four atom wide (111) terraces interrupted by monoatomic steps of the different step geometries: (100) versus (110), respectively. We…
In this study, angiopep with high transcytosis capacity and parenchymal accumulation was used as a novel ligand for the brain-targeting delivery of poly(ethylene glycol)-block-poly(D,L-lactide acid) (PEG-PLA) micelles. Angiopep-2 was synthesized by solid-phase peptide synthesis, and then conjugated with maleimide-PEG-…
We report the effects of N 2 and O 2 on the electrical properties of PbSe quantum-dot (QD) films treated with 1,2-ethanedithiol (EDT) by measuring the changes in the current−voltage characteristics of QD field-effect transistors (FETs). EDT-treated PbSe QD films at a base pressure of ∼10 −5 Torr exhibit ambipolar tran…
The precursors for boehmite and γ-Al 2 O 3, aluminum acetate hydroxide [(CH 3 COO) 2 Al(OH)] with various morphologies including nanoleave, nanofibers, and hierarchically nanostructured microflowers, have been successfully synthesized by an ionic liquid-assisted hydrothermal synthetic method using 1-butyl-2, 3-dimethy…
Reduced graphene oxide thin-film transistors exhibit unique channel-length-dependent field-effect mobilities and carrier concentrations due to their structural and electronic properties. Increase in these characteristics with decreasing channel length is a consequence of the hopping transport from nanosheet to nanoshe…
A facile and powerful pH-responsive polymeric micelle encapsulates Fe3O4 nanoparticles as an acid-targeting MRI contrast agent for pathologic diagnosis. This MRI probe remains in a micellar state in the physiological environment whereas it can be dissolved in acidic pathological areas. More biomedical applications wil…
We report a confocal Raman study on edges of single-layer graphene. It is found that edge orientations could be identified by G mode in addition to D mode. We observe that G mode at the edges of single-layer graphene exhibits polar behaviors and different edges such as zigzag- or armchair-dominated responses different…
We report superconducting (SC) properties of stoichiometric LiFeAs (${T}_{c}=17\text{ }\text{ }\mathrm{K}$) studied by small-angle neutron scattering (SANS) and angle-resolved photoemission (ARPES). Although the vortex lattice exhibits no long-range order, well-defined SANS rocking curves indicate better ordering than…
IMPORTANCE OF THE FIELD: Taxanes are agents for the treatment of breast cancer. Paclitaxel is hydrophobic, and available formulations require polyoxyethylated castor oil, Cremphor EL (CrEL) and an ethanol vehicle to allow parental administration. Nanoparticle albumin-bound paclitaxel (nab-P) is a CrEL-free formulation…
Hydrogen storage is a significant challenge for the development and viability of hydrogen-powered vehicles. Storage of molecular hydrogen in nitrogen-substituted polyunsaturated aromatic organic molecules through reversible catalytic hydrogenation and dehydrogenation is a promising approach. The success of developing…
We demonstrate that the valence energy-loss function of hexagonal boron nitride (hBN) displays a strong anisotropy in shape, excitation energy and dispersion for momentum transfer q parallel or perpendicular to the hBN layers. This is manifested by e.g. an energy shift of 0.7 eV that cannot be captured by single-parti…
Using the classical molecular dynamics and the semiempirical Brenner's potential, we theoretically study the interlayer sigma bond formation, as cooperative and nonlinear phenomena induced by visible light excitations of a graphite crystal. We have found several cases, wherein the excitations of certain lattice sites…
