A mesostructured chalcogenide built from Chevrel-type clusters [(Re(6)Se(6)Br(2))Br(6)(T)](2-) linked by ditopic [Se(3)](2-) anions and synthesized in the presence of a cationic surfactant template is reported. This new mesophase, h-C(18)PyReSeBr, exhibits remarkably well ordered hexagonal symmetry from which a reason…

A method for rapid and quantitative chemical modification of poly(vinyl alcohol) (PVOH) is described using two different ionic liquids as reaction solvents. The quantitative modification of alcohol-containing polymers such as PVOH, cellulose, and other polysaccharides has been elusive due to solvent incompatibility wi…

We study smooth, slightly inelastic particles flowing under gravity on a bumpy inclined plane using event-driven and discrete-element simulations. Shallow layers (ten particle diameters) are used to enable simulation using the event-driven method within reasonable computational times. Steady flows are obtained in a na…

Here we report the single phase nanostructured Gd3Fe5O12 garnets with different grain sizes (bulk, 75, 47, 35, and 22 nm) were prepared by ball milling for various milling times. Both the average grain size and the lattice parameter were estimated from the x-ray diffraction line broadening. The F57e Mössbauer spectra…

A type of square Fresnel zone plate with spiral phase for generating zero axial irradiance is proposed. Diffraction patterns of the zone plates with different generalized topological charges are given by numerical simulation, which also suggests their potential applications in generating hollow beams.

We introduce a photonic crystal hetero-slab-edge microcavity design with surface mode, which is beneficial for optical index sensing. The simulated index sensitivity (R(n)) as high as 675 nm per refractive index unit (nm/RIU) variation is obtained with slab thickness of 180 nm. In experiments, single surface mode lasi…

Abstract This article writen by one of the originators of LOPA, focuses on problems observed with LOPA. One the biggest issues is that organizations use LOPA without following the rules for LOPA, especially the rules related to maintaining, testing, and record‐keeping for each independent protection layer (IPL) and fo…

Using an efficient Monte Carlo approach known as Aggregation-Volume-bias Monte Carlo with self-adaptive Umbrella Sampling and Histogram Reweighting (AVUS-HR), we obtained the nucleation free energy profile of 1-pentanol at various temperatures from 220 to 360 K. From these profiles, differences between the free energy…

The parameters of fullerene C(60) dissolved in carbon disulfide CS(2) are analyzed by small-angle neutron scattering (SANS) in a wide interval of momentum transfer. To exclude the influence of nonequilibrium conditions, the solutions are prepared without applying shaking, stirring or ultrasound. No indication of the e…

We developed a through-substrate copper-damascene interconnect technology in silicon with minimal impedance. Via impedance was extracted using parameter measurements at 50 GHz that were matched to simple circuit models. The extracted impedance shows resistances ≤ 1 Ω, record-low inductance for aspect ratios > 4, and s…

The small heat shock protein (smHsp) Lo18 from lactic acid bacteria Oenococcus oeni reduces in vitro thermal aggregation of proteins and modulates the membrane fluidity of native liposomes. An absence of information relating to the way in which the smHsp demonstrates a stabilizing effect for both proteins and membrane…

Abstract TlPd3was synthesised from the elements in evacuated silica tubes at 600 °C. Alternatively, TlPd3was yielded by reduction of TlPd3O4in N2gas atmosphere. Reduction of the oxide in H2gas atmosphere resulted in the formation of the new hydride TlPd3H. The structure of tetragonal TlPd3(ZrAl3type, space groupI4/mmm…

The adsorption behavior of CO on a 2 ML thin MgO/Ag(001) film is investigated with scanning tunneling microscopy and spectroscopy at 5 K. Depending on the tip state, single CO molecules are imaged as Gaussian depressions or ring-like features on the oxide surface. The preferred CO adsorption sites are identified as th…

The bulk conductivity of polycrystalline 1 mol-% Fe-doped rutile TiO 2 has been measured as a function of p H 2 O and temperature under oxidizing and reducing conditions. From the p H 2 O -dependency of the conductivity, it is concluded that protons are significant positive defects and, furthermore, that mixed p -type…

Small heat shock proteins (sHsps) associate with aggregated proteins, changing their physical properties in such a way that chaperone mediated disaggregation becomes much more efficient. In Escherichia coli two small Hsps, IbpA and IbpB, exist. They are 48% identical at the amino acid level, yet their roles in stabili…
