Structural investigation of polymers
This book is split into two sections; the first covers the characterisation of polymer molecules with respect to chemical composition, configuration and molecular mass, while the second and larger section is a thorough discussion of polymer morphology and the techniques used in its investigation.Each chapter of the bo…
Changes in wettability with time of plasma-modified perfluorinated polymers
Treatment of fluorinated ethylene propylene (FEP) and polytetrafluoroethylene (PTFE) by plasmas established in water vapour or ammonia gas enabled the rapid and facile modification of their surface chemistries. Under comparable plasma conditions, ammonia plasma exposures produced considerably lower air/water contact a…
Photochemistry on surfaces: fluorescence emission quantum yield evaluation of dyes adsorbed on microcrystalline cellulose
A simple method to determine the fluorescence quantum yield (ϕF) of dyes adsorbed on microcrystalline cellulose is presented. The method is based on corrected fluorescence emission spectra and can easily be applied provided the energy profile of excitation is accurately determined. The quantitative determination of ϕF…
X-Ray crystal structure of a mesogenic octa-substituted phthalocyanine
Crystals of 1,4,8,11,15,18,22,25-octahexylphthalocyanine are composed of tilted stacks of molecules with an unexpectedly large separation between the aromatic cores.
Fracture Toughness and Thermal Shock Behavior of Silicon Nitride–Boron Nitride Ceramics
Fracture toughness behavior, stress–strain behavior, and flaw resistance of pressureless‐sintered Si 3 N 4 ‐BN ceramics are investigated. The results are discussed with respect to the reported thermal shock behavior of these composites. Although the materials behave linear‐elastic and exhibit no R ‐curve behavior, the…
Mechanical Properties and Microstructure of Si<sub>3</sub>N<sub>4</sub> Matrix Composite with Nano-Meter Scale SiC Particles
Si3N4 matrix composites with dispersed SiC particles were prepared by hot-pressing compacts of powder mixtures of sub-micron size SiC and Si3N4 particles. SiC particles in nano-meter scale were dispersed uniformly inside Si3N4 grains. After adding SiC particles, the configuration of β-Si3N4 grains changed from equiaxe…

Chemical reactivity between Teflon surfaces subjected to argon plasma treatment and atmospheric oxygen
Surface modification of two Teflon polymers, PFA (tetrafluoroethylene and perfluoroalkoxyvinyl ether copolymer) and PTFE (polytetrafluoroethylene), induced by argon plasma treatment using a radio frequency generator and subsequent air exposure has been investigated by x-ray photoelectron spectroscopy (XPS) and electro…

Micritized skeletal grains in northern Belize Lagoon; a major source of Mg-calcite mud
Abstract Lime mud in northern Belize lagoon is composed predominantly of silt-size cryptocrystalline grains and clay-size clumps, both of which consist of anhedral, equant crystals less than 0.5 mu m in size. This mud is 70-90% Mg-calcite containing 9-10 mole % MgCO 3 . Detailed petrographic, morphologic and mineralog…
Copper and nickel complexes of 1,8-disubstituted derivatives of 1,4,8,11-tetraazacyclotetradecane
The stereoselective synthesis of various 1,8-disubstituted derivatives of 1,4,8,11-tetraazacyclotetradecane (cyclam) has been achieved and copper and nickel complexes prepared. For the 1,8-dibutyl derivative, the square-planar nickel(II) complex exists as two diastereoisomers, as revealed by crystallographic analysis.…

Solid defect structure and catalytic activity of perovskite-type catalysts La 1–x Sr x NiO 3–λ and La 1–1.333x Th x NiO 3–λ
Two series of La1–xSrxNiO3–λ and La1–1.333xThxNiO3–λ catalysts have been prepared, and the relationships between the solid defect structure and catalytic activity for NH3 oxidation were measured. The results showed that in the range of x < 0.3, the samples possessed single perovskite-type structure, and as the content…
Study on the prevention of surface-induced platelet activation by albumin coating
To understand how albumin on the surface inhibits surface-induced platelet activation, we adsorbed albumin on dimethyldichlorosilane-coated glass (DDS-glass) and modified the adsorbed albumin by three different methods. The adsorbed albumin was crosslinked with glutaraldehyde, dried and rehydrated, or digested with tr…

Grafting of electronically conducting polyaniline on insulating surfaces
A method is described to graft conducting polyaniline onto glass fabric, glass wool and nylon cloth to impart flexibility and mechanical strength to the polyaniline, which is otherwise powdery and untracable. These flexible conductive surfaces can find application as antistatic shields.
