Herein we demonstrate a new, straightforward method for the synthesis of macroporous hybrid polymers coated with gold nanorods, which are strongly and uniformly attached to the surface of pores.
We report the possibility of broad-band spectral modification based on quantum cutting (QC), which converts one UV or visible photon into two near-IR photons in ion co-doped aluminosilicate glasses. Metal Al powder is added to the host glass composition to reduce to during melting in air. The existence of europium in…
A process for nitric oxides ( NO x , NO plus NO 2 ) removal by solid oxide fuel cells (SOFCs) can easily reduce NO x in the flue gases to zero and also generate an electrical current. An yttria-stabilized zirconia electrolyte-supported SOFC unit cell was constructed with Ni–gadolinia-doped ceria (GDC) as the anode and…
In this book some 50 papers published by K A Müller as author or co-author over several decades, amplified by more recent work mainly by T W Kool with collaborators, are reproduced. The main subject is Electron Paramagnetic Resonance (EPR) applied to the study of perovskites and other oxides with related subjects. Thi…
The rheological properties and processing of polymer nanocomposites with dispersed nanometer-thick layered silicates are reviewed. The linear viscoelastic properties reflect the nanoscale dispersion of the silicate layers and the mesoscale structure that such dispersed layers or their aggregates form. The linear visco…
The dilute lamellar phase of the nonionic surfactant C12EO5 was doped with goethite (iron oxide) nanorods up to a fraction of 5 vol%. The interaction between the inclusions and the host phase was studied by polarized optical microscopy (with or without an applied magnetic field) and by small-angle x-ray scattering. We…
We investigate the wetting properties of surfaces patterned with fine elastic hairs, with an emphasis on identifying superhydrophobic states on hydrophilic hairs. We formulate a 2D model of a large drop in contact with a row of equispaced elastic hairs and, by minimizing the free energy of the model, identify the stab…
In this paper nanofibres were formed from PVA solution with potato starch and a small amount of ethanol. Due to the previous study, it was determined that with the addition of ethanol (30 wt.%) in the solution, it is possible to form bicomponent PVA/cationic starch (75/25 wt.%) nanofibres. Preparation of a procedure u…

In this study, we developed a new drug delivery system using anodic oxidation. The growth of a porous oxide layer on aluminum under anodic bias in various electrolytes has been studied for more than 40 years. Anodic Aluminum Oxide (AAO) has many uniform nanopores on its surface. This nanoporous surface can be used for…
The aggregate size of cellulose dissolved in 1-ethyl-3-methylimidazolium acetate (EMIMAc) and 1-butyl-3-methylimidazoluim chloride (BMIMCl) was measured by static and dynamic light scattering. Examined were cellulose solutions containing various amounts of water. The impact of water on the size of cellulose particles…
A mixture of MgO and graphite with a molar ratio (1 : 1) was subjected to planetary ball milling for 1, 2, 4, and 8 h with the intention of enhancing carbothermic reduction reaction of MgO during subsequent thermal treatment. Unmilled and milled mixtures were characterized using a combination of X-ray diffraction (XRD…
In this communication, we demonstrate that certain kinds of Rh porphyrins on carbon black can electrochemically oxidize aldose at low potentials. The onset potential was much lower than those with the other complex-based catalysts. A product analysis suggested that this reaction involves 2-electron oxidation of the al…
The viscous flow of oxide driven by the electrostriction force during the growth of anodic aluminum oxide is treated by linear stability and scale analysis. A uniform oxide film is unstable to a periodic deformation. The restabilization of pore growth is examined by scale analysis of the steady pore diameter. The patt…
The electrochemical preparation of poly(3,4-ethylenedioxythiophene) (PEDOT) is conducted in liquid crystal (LC) electrolyte solution with nematic (N), cholesteric (Ch*), and smectic A (SmA) phases under a magnetic field. The polymer imprints the molecular arrangement of the LC electrolyte during the polymerisation pro…
Strontium-substituted lanthanum manganite/yttria-stabilized zirconia (LSM/YSZ) solid oxide fuel cell (SOFC) composite electrodes were fabricated with slurry spraying on both sides on either pure YSZ electrolyte foils or YSZ electrolyte foils with a cerium–gadolinium oxide (CGO) barrier layer made by spin coating. Elec…
Assembly of mesostructured silica using Pluronic P123 triblock copolymer (EO20-PO70-EO20) and n-butanol is a facile synthesis route to the MCM-48-like ordered large mesoporous silicas with the cubic Iad mesostructure, which are designated KIT-6. This synthesis route has been successfully extended to phenylene-bridged…
Glycerol-plasticized corn starch materials (TPS), reinforced with calcium bentonite, were prepared by melt extrusion. Scanning electron microscopy was used to visualize extrudates morphology. The effects of clay content and of glycerol content on physical properties of extrudates were evaluated. As determined by X-ray…
The corrosion resistance of the new Ti-6Al-4V-1Zr alloy in comparison with ternary Ti-6Al-4V alloy in Ringer-Brown solution and artificial Carter-Brugirard saliva of different pH values was studied. In Ringer-Brown solution, the new alloy presented an improvement of all electrochemical parameters due to the alloying w…
A tubular solid oxide fuel cell stack was modeled, and its operation on biomass syngas was investigated. The objective of this work was to develop a computer simulation model of a biomass gasification–solid oxide fuel cell system capable of predicting performance under various operating conditions and using diverse fu…
