Abstract Silicon carbide was incorporated in poly(dimethyl siloxane) (PDMS) in combination with multiwall carbon nanotubes (MWCNTs) to improve the thermal conduction behavior. The amount of silicon carbide was increased from 0 to 150 phr and the amount of MWCNTs was increased from 0 to 8 phr at a fixed amount of silic…
The interaction between heparin, a polyanion, and a polycationic dendrimer with a glycine core and lysine branches Gly-Lys63(NH2)64 has been investigated. Complexation was assessed by transmission electron microscopy, size and zeta potential measurements, methylene blue spectroscopy, and measuring the anti-coagulant a…
Abstract A model is developed to predict rates of undesirable reactions in the low‐moisture, high‐temperature finishing stage of nylon 66 production. The model contains 56 unknown parameters and initial conditions, which are ranked based on their influence on model predictions, correlation with other parameters and un…
Staphylococcus aureus is an opportunistic Gram-positive bacterium which causes a wide variety of diseases ranging from minor skin infections to potentially fatal conditions such as pneumonia, meningitis and septicaemia. The pathogen is a leading cause of nosocomial acquired infections, a problem that is exacerbated by…
Adsorption of Pb monomers (Pb-m) and Pb dimers (Pb-d) on graphene containing single vacancies was studied using density functional theory. We found that both Pb-m and Pb-d can chemically bind to graphene and turn the systems into semiconductors with moderate energy gaps. The spin–orbit (SO) splitting of the bands is s…
Lepidoperan silks provide a superb opportunity for comparative studies of spinning and fiber characteristics. Comparing the four species, Bombyx mori (China), Actias selene (India), Antheraea yamamai (Japan), Gonometa postica (Africa), allows us to examine differences on the family, species, and race levels. Measured…
Abstract Titanium and vanadium oxide layers have been grown in the pores of two 2D hexagonal ordered mesoporous materials: SBA‐15 (silica) and FDU‐15 (phenol/formaldehyde resin). The deposition of the layers was controlled by the self‐limiting reaction of the metal oxide precursor with the hydroxyl surface. Single, mu…
A broad working definition of structural proteomics (SP) is that it is the process of the high-throughput characterization of the three-dimensional structures of biological macromolecules. Recently, the process for protein structure determination has become highly automated and SP platforms have been established aroun…
Quadratisch, praktisch, gut: Zwei quadratisch-planare High-Spin-{MO4}-Komplexe wurden hergestellt, darunter das erste molekulare Beispiel mit M=CoII (siehe Struktur). Die Bestimmung der Strukturen, spektroskopischen Eigenschaften und magnetischen Suszeptibilitäten ermöglicht eine Spezifizierung der Ligandmerkmale, die…
We present density functional calculations of the adsorption of a single Au atom on the $h$-BN/Rh(111) nanomesh and compare it to Au adsorption on a pure $h$-BN surface. While Au binds only weakly to pure $h$-BN (similar to graphene) or to BN at the ``wires'' of the nanomesh, the subsurface Rh atoms in the ``pores'' o…
Abstract Biofouling that involves protein adsorption, cell and bacteria adhesion, and biofilm formation between a surface and biological entities is a great challenge for biomedical and industry applications. In this work, L ‐tyrosine‐derived polyurethanes ( L ‐polyurethane) with different molecular weights of poly(et…
The effect of Cu doping on the properties of small gold cluster cations is investigated in a joint experimental and theoretical study. Temperature-dependent Ar tagging of the clusters serves as a structural probe and indicates no significant alteration of the geometry of Au(n) (+) (n = 1-16) upon Cu doping. Experiment…
The physical properties of sodium borosilicate glasses were calculated directly from their chemical compositions in the whole glass‐forming region. These properties included molar volume, refractive index, thermal expansion coefficient, elastic moduli, and glass transition temperature. The physical property values cor…
Post‐test microscopy evaluations were performed on borosilicate ( B orofloat ® 33) and soda‐lime ( S tarphire ® ) glass specimens following confined compression tests. These included optical and electron microscopy investigations of select specimens tested at low strain rates with confinement pressures up to 1 GPa. Sp…

As an absorber of microwave, the Al and N co‐doped SiC powders have been synthesized by combustion synthesis in a nitrogen or argon atmosphere, using silicon and carbon black as the raw material, polytetrafluoroethylene as the chemical activator, aluminum and ammonium chloride ( NH 4 Cl ) as the doping resource, respe…
The photocatalytic process is considered as one of the advanced oxidation processes (AOPs) for the degradation/mineralization of pollutants, and it is known that ultrasound can significantly enhance these reactions when combined with photocatalytic processes. However little is known about the design parameters of thes…
Polymorphic magnetization behavior has been observed experimentally in the Heusler alloy Mn${}_{2}$NiGa in which Co has been substituted for Ni or Ga. The magnetization of the austenitic phase can be enhanced up to 132 emu/g, when more than 50$%$ of the antiferromagnetic couplings between Mn atoms are changed to ferro…
An electromechanical diode nonvolatile memory cell design is proposed for implementation of compact (4F2) cross-point memory arrays. The first prototype cells are demonstrated to operate with relatively low set/reset voltages and excellent retention characteristics and are multi-time programmable (with endurance excee…
Leonhardt (2009 New J. Phys. 11 093040) demonstrated that the two-dimensional (2D) Maxwell fish eye (MFE) lens can focus perfectly 2D Helmholtz waves of arbitrary frequency; that is, it can transport perfectly an outward (monopole) 2D Helmholtz wave field, generated by a point source, towards a 'perfect point drain' l…
