The filling of carbon nanotubes with palladium metal crystallites is described and it is shown that when the carbon nanotube samples are opened using nitric acid, surface acid groups (CO2H and OH) are present on both the nanotubes and nanoparticles and these interact strongly with palladium ions: ultrasound pre-treatm…
Experiments are described which demonstrate that particle velocity fluctuations and hydrodynamic self-diffusivities of sedimenting non-Brownian spheres do not vary as the inner width of the vessel varies by a factor of 4.
Adhesion of cells to a biomaterial surface can be a major factor mediating its biocompatibility. In this investigation, jet impingement techniques were used to quantify strength of cellular adhesion to various material surfaces. The metals tested: HS25 (a cobalt-based alloy similar to F75), 316L stainless steel, Ti-6A…
Adsorption of O2, using either normal oxygen or 17O-enriched mixtures, on CeO2 outgassed at different temperatures has been studied by EPR and FTIR. Different signals, assigned to O2– species bonded to surface cerium ions, were observed depending on the vacuum treatment temperature Tv, a parameter that determines the…
Glycerin-plasticized soy protein films were produced by casting heated alkaline (pH 8.5) protein solutions. Acetic anhydride, succinic anhydride, calcium cations, and formaldehyde were added to the film-forming solutions and their effects on film water solubility (WS), tensile strength (TS), puncture strength (PS), wa…

The effects of exposure to ultraviolet (UV) light and ozone, separately and in combination, were investigated with respect to polypropylene (PP) and poly(ethylene terephthalate) (PET) surfaces. Three combinations of UV light and ozone were studied: ozone only, UV light in air (producing ozone), and UV light in air (pr…
Irene Emery was one of America's leading authorities on ancient fabrics and textiles before her death in 1981. Her studies led her to become increasingly concerned with the haphazard and confusing terminology for describing fabrics in a precise way, and she began serious study of this problem at the Laboratory of Anth…
A new atomic electron-density function is derived by Fourier transformation of resolution-truncated atomic scattering factors. It forms the basis of a new real-space refinement method, RSREF, that is a substantial improvement on prior implementations that did not formally consider the absence of high-resolution terms…
Three types of polymer-protected bimetallic clusters of noble-metals, prepared by simultaneous alcohol reduction, have been totally shown to have special ‘core-shell’ structures, on the basis of X-ray diffraction and quantitative X-ray photoelectron spectroscopic measurements. In situ UV–VIS spectral changes during th…
Type I collagen, the most abundant protein of the body, is preferentially synthesized in bone, dermis, and tendons by two cell types, the osteoblast and the fibroblast. The expression of type I collagen is increased in the various forms of fibrosis such as lung, liver, bone marrow fibrosis and scleroderma. Type I coll…

Comparison of the structures of four monomanganese (and one monoiron) complexes of ligands with the identical donor [N3(O–)3] set reveals that geometry determines the redox state of the cation.
A low-lying S= 15/2 ground state in a heptanuclear CrIIINiII6 species arises from the ferromagnetic interaction (J= 16.8 cm–1) between one central CrIII(S= 3/2) and six peripheral NiII(S= 1) ions through the cyanide bridge.

The process of the decrease of the surface area due to crystallite growth in ceria at 943 K is described by a kinetic model involving oxygen and cerium diffusion. The experimentally found variations in the rate of crystallite growth are reported as a function of the content (⩽ 10% cat.) of dopants, which are the catio…

The present paper deals with the photophysical properties of columnar liquid crystals formed by hexakis-(alky1oxy)triphenylenes. Absorption and fluorescence spectra of solutions are analyzed on the basis of quantum chemical calculations performed by the CS-INDO-CI (conformations spectra-intermediate neglect of differe…
