Abstract In this work, high‐performance dye‐sensitized solar cells (DSSCs) based on new low‐cost visible nickel complex dye (VisDye), TiO2 nanoparticle/nanotube composites electrodes, carbon nanoparticles counter electrodes, and ionic liquids electrolytes have been fabricated. The electronic structure, optical spectro…
Specimens of the Neogene marine diatom Thalassiosira dolmatovae have been studied with a scanning electron microscope for the first time. The observations revealed the morphological features typical of this species including arrangement of different kinds of processes. T. dolmatovae has one single subcentral strutted…
Purpose – A series of polyurethane/bishydroxyl-terminated polydimethylsiloxane composites (PU/BTPDMS) were prepared. The effect of BTPDMS content on the tribological properties of the PU/BTPDMS composites was studied. The paper aims to discuss these issues. Design/methodology/approach – The composites were prepared by…
A new species of Encyonema is described from the benthos of small mountain streams and rivers in western Montana and northern Wyoming. Previously this species had been identified incorrectly as E. hebridicum Grunow ex Cleve and Cymbella affinis Kützing or assigned the provisional name Encyonema sp. 1 MONTANA HAMSHER A…
It is shown that metal surface with a nanohole can support surface plasmon-polaritons (SPP), whose wave fields are described by Hankel functions. These plasmons can be excited by an electromagnetic wave incident at the metal surface. The optical transmission through subwavelength holes in metal films can essentially b…
The non-renewable fossil resources currently exploited by the oil and gas industries are the objects of growing concern owing to their finite supply and contribution to global warming. Lignocellulosic biomass is a sustainable alternative to fossil resources, and has the added advantage of not competing with human and…
Nurnerical analysis is applied with a stratigraphic purpose using the System of Multivariate Computer Programs (NT-SYS) of Rohlf, Kishpaug and Kirk. The Operational Taxonomic Units (OTU) are the samples (sediments ) of different surface and subsurface sections, wich have already been used in the previous contribution.…
An unusual, non-metallic resistivity of the 111 iron-pnictide compound FeCrAs is shown to be relatively unchanged under pressures of up to 17 GPa. Combined with our previous finding that this non-metallic behaviour persists from at least 80 mK to 800 K, this shows that the non-metallic phase is exceptionally robust. A…
Using first principles density functional theory, we predict new multiferroic compounds Ho1/2A1/2MnO3 (A = As, Sb, Bi) with enhanced polarization. We find that doping of lone pair cations with different ionic radii, at the A-site of orthorhombic HoMnO3, results in a marked increase of the electronic polarization and i…
The experimental method for physical modeling of operating conditions of a continuous billet casting machine (CCM) rolls is developed to estimation the temperature field and especially the temperature at the surface of the roll by measuring the temperature with the thermocouples (fully embedded) at multiple point insi…
We have carried out static compression tests in the poling direction for PZT ceramics and evaluated the material properties by measuring the resonance and anti-resonance frequencies and electrostatic capacity at regular intervals. Then the variation in the material properties up to fracture was clarified. Also, the de…
Halophilic proteins are characterized by high net negative charges and relatively small fraction of hydrophobic amino acids, rendering them aggregation resistant. These properties are also shared by histidine-rich metal binding protein (HP) from moderate halophile, Chromohalobacter salexigens, used in this study. Here…
The use of highly brilliant synchrotron radiation provided by third-generation storage rings allows precise structure analyses of crystalline materials by means of X-ray diffraction. However, a variety of experiments is limited on the part of presently available detectors. The possibility to measure simultaneous posit…
New families of stable copper complexes address an old challenge: providing brightly luminescent, easily accessible materials with good solubility and sufficient stability for wet-processing organic LEDs.
Abstract Novel composite carbon particles are developed that can self‐assemble as a coating on a substrate without a binder. These carbon particles were used as a coating to enhance thermal dissipation and their thermal conductivity, surface emissivity and cooling performance were measured. Carbon particles with both…
Cellulose, a natural polymer, has been widely used in blood purification due to its good biocompatibility, and excellent processing which can be easily formulated into beads, membranes and hollow fibers. Sorbent-perfusion is a novel approach of blood purification which can specifically remove endogenous and exogenous…
A systematic method for the analysis of the hydration structure of proteins is demonstrated on the case study of lysozyme. The method utilises multiple structural data of the same protein deposited in the protein data bank. Clusters of high water occupancy are localised and characterised in terms of their interaction…
Relict assemblages of arctic, sub-arctic, and boreal diatoms were found intact in two undisturbed floating-mat fens at 47o north latitude and 1,830 m elevation in the Rocky Mountains of western Montana, USA. The fens support Encyonema droseraphilum sp. nov. and several rare northern/alpine diatom species—including ele…
We report magnetic, transport, and neutron diffraction measurements as well as a doping study of the V-phase compound Zr${}_{4}$Fe${}_{4}$Si${}_{7}$. This compound exhibits collinear antiferromagnetic order below ${T}_{N}=98\ifmmode\pm\else\textpm\fi{}1$ K with a staggered moment of 0.57(3)${\ensuremath{\mu}}_{B}/$Fe…
Polylactide (PLA) bearing hemin coupling moieties was prepared by a reaction between the two carboxylic groups of hemin and amino groups of amino-terminated PLA and characterized by UV-Vis, IR, and 1H NMR spectra and gel permeation chromatography. Blank microparticles and microparticles loaded with bovine serum albumi…
