We study the four-point dynamic susceptibility chi4(t) obtained from Brownian dynamics computer simulations of the Kob-Andersen Lennard-Jones mixture. We compare the results of the simulations with qualitative predictions of the mode-coupling theory. In addition, we test an estimate of the four-point susceptibility re…
The structural, electronic, and magnetic properties of a ${\mathrm{Mn}}_{x}{\mathrm{Ge}}_{1\ensuremath{-}x}$ alloy prepared through room-temperature ion implantation ($100\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$, $2\ifmmode\times\else\texttimes\fi{}{10}^{16}\phantom{\rule{0.3em}{0ex}}\text{ions}∕{\mathrm{cm}}^{2}$) an…
Durch den Liganden erzwungen: Der MnIII6CrIII-Komplex 1, aufgebaut aus zwei dreikernigen Mangan-Tripelsalen-Komplexen und einem Hexacyanidochromat, hat einen St=21/2-Spingrundzustand. Die durch den Tripelsalen-Liganden erzwungene dreizählige Symmetrie verhindert die vollständige Auslöschung der lokalen magnetischen An…
Aspartate-beta-semialdehyde dehydrogenase (ASADH) catalyzes a critical branch point transformation in amino acid bio-synthesis. The products of the aspartate pathway are essential in microorganisms, and this entire pathway is absent in mammals, making this enzyme an attractive target for antibiotic development. The fi…
We perform molecular simulations to study the self-assembly of block copolymer tethered cubic nanoparticles. Minimal models of the tethered nanoscale building blocks (NBBs) are utilized to explore the structures arising from self-assembly. We demonstrate that attaching a rigid nanocube to a diblock copolymer affects t…
We propose here a model for describing mesoscale relaxation mechanisms in soft thermoplastic elastomers, and also in the high-temperature regime of filled rubbers. The model is solved by dissipative particle dynamics. We study the response of these systems to deformations of various amplitudes and show that the system…
Novel dibenzocoronenetetracarboxylic acid diimide analogues and naphthoperylenetetracarboxylic acid diimide analogues containing imidazole, 1,2,4-triazole, and pyrazole rings embedded as functional constituents within the parent hydrocarbon backbone have been synthesized. The pi-rich and pi-poor heterocycles have diff…
Ti 3 SiC 2 is synthesized by self‐propagating high‐temperature synthesis (SHS) of elemental titanium, silicon, and graphite powders. The reaction paths and structure evolution are studied in situ during the SHS of the 3Ti+Si+2C mixture by time‐resolved X‐ray diffraction coupled with infrared thermography. The proposed…
Ethynyl-terminated fluorinated poly(arylene ether sulfide) (E-FPAESI) was synthesized via nucleophilic aromatic substitution from dihydroxy monomer and pentafluorophenyl sulfide, followed by the reaction with 3-ethynylphenol. Dihydroxy monomer was synthesized in four steps via bromination, Grignard, Suzuki cross-coupl…
SrTiO 3 (100) epitaxial films with thicknesses of 3, 1 μm, and 250 nm were prepared on MgO (100) substrates by pulsed‐laser deposition. The electrical conductivities of the thin films were systematically investigated as a function of temperature and ambient oxygen partial pressure. This was made possible by using a sp…
Numerical simulations are presented of shear flow past two-dimensional droplets adhering to a wall, at moderate Reynolds numbers. The results were obtained using a level-set method to track the interface, with measures to eliminate any errors in the conservation of mass of droplets. First, the case of droplets whose c…
Abstract Summary: PANCMPCs containing phospholipid side moieties were electrospun into nanofibers with a mean diameter of 90 nm. Field emission SEM was used to characterize the morphologies of the nanofibers. These phospholipid‐modified nanofibers were explored as supports for enzyme immobilization due to the characte…
X-ray photon correlation spectroscopy was used to characterize the wave vector- and temperature-dependent dynamics of spontaneous thermal fluctuations in a sponge (L3) phase that occurs in a blend of a symmetric poly(styrene-ethylene/butylene-styrene) triblock copolymer with a polystyrene homopolymer. Measurements of…

Novel applications for flexible electronics, e.g., displays and solar cells, require fully flexible, transparent, stable, and low-work-function electrodes that can be manufactured via a low-cost process. Here, we demonstrate that surface chemistry constitutes a route to producing transparent low-work-function plastic…

Abstract A high‐performance, low‐dielectric‐constant polyimide (PI) nanocomposite from poly(amic acid) (PAA) cured with a reactive fluorine polyhedral oligomeric silsesquioxane (POSS) isomer was successfully synthesized. The features of this reactive fluorine POSS isomer [octakis(dimethylsiloxyhexafluoropropylglycidyl…
Self-sacrifice: Poly(acrylic acid) was used to tune the diameter of 1D nanowires prepared from linear Cd2+/thioglycolic acid coordination polymer chains. The nanowires were then employed as sacrificial templates for preparing long CdTe nanotubes of different diameters (see the TEM images).
Cisplatin is the most effective cytotoxic agent against many cancers. Its usage, however, is limited due to inefficient uptake by the target cells. A liposomal formulation of cisplatin is reported to partly overcome this limitation. Physicochemical characteristics of the liposome-cisplatin preparation, including its s…
Generation of hydrogen via the hydrolysis of sodium borohydride (NaBH 4 ) solution in the presence of metal catalysts is a promising method for hydrogen storage. The concentration of NabH 4 should be as high as possible in order to improve energy density. On the other hand, NaBO 2 is produced after the hydrolysis of N…
