Photodecomposition of poly(methylmethacrylate) thin films by monochromatic soft x-ray radiation
The photofragmentation reaction of poly(methylmethacrylate) (PMMA) by soft x-ray irradiation was investigated by measuring the yield of released neutral fragments and the changes in the absorption spectra in the carbon and oxygen K-edge regions. Films of 0.4–1.0 μm thicknesses were irradiated with various doses of mon…
Spectroscopic Investigation of a Polypyrrole / MoS4 2 − / MoS3 Composite Film Electrode in Aqueous KCl Solution
Polypyrrole‐tetrathiomolybdate‐molybdenum trisulfide, , thin film coated tin oxide electrodes have been studied by UV‐visible spectroscopy. The films are obtained by electrochemical polymerization from an aqueous solution of 0.5 M pyrrole and 0.5 m M at a potential of 0.7 V vs. SCE. The UV‐visible spectroscopy data su…
XPS and SEM characterization of hydrated cerium oxide conversion coatings
Abstract Cerium‐rich conversion coatings have been deposited onto aluminium 2024‐T351 alloy by immersion into a solution containing 10 g L −1 CeCl 3 and 1% H 2 O 2 in a process described as ‘cerating’. Prior to deposition the alloy had been prepared either by using a standard chemical pretreatment used for aerospace a…

High‐Temperature Mechanical Behavior of Stoichiometric Magnesium Spinel
The elastic and mechanical behavior, from room temperature up to 1300 deg; C, of Stoichiometric polycrystalline magnesium aluminum spinel is studied. Elastic modulus, fracture toughness, and modulus of rupture measurements and observations of polished and fracture surfaces have been performed. Two well‐differentiated…

Calculation of self and mutual impedances in planar magnetic structures
The high frequency operation of magnetic components, in applications such as filters, makes them ideal candidates for thick film technology along with resistors and capacitors. This in turn leads to distinct advantages over labor intensive wire wound components: improved reliability, repeatability, accuracy and conseq…

Delocalization in inelastic scattering
How delocalized is an EELS signal? For instance, how far from a silicon atom must the electron probe be before a Si edge can be detected? A crude estimate of a localization length (λθE) suggests a maximum impact parameter of 50 Å for a typical plasmon loss. Yet with care, subnanometer resolution plasmon maps can be ac…
Fatigue and Fracture of Elastomers
Abstract The use of an energetics approach to treat various aspects of fatigue and fracture in elastomers is reviewed. Topics covered include tearing, crack growth and fatigue, tensile failure, oxidative effects, environmental cracking, cutting by sharp objects, abrasion, adhesion, friction (under circumstances where…

Disorder-driven pretransitional tweed pattern in martensitic transformations
Defying the conventional wisdom regarding first-order transitions, solid-solid displacive transformations are often accompanied by pronounced pretransitional phenomena. Generally, these phenomena are indicative of some mesoscopic lattice deformation that ``anticipates'' the upcoming phase transition. Among these precu…
Thermal conductivity of sputtered oxide films
The thermal conductivity of oxide thin films deposited using dc, rf, and ion-beam sputtering is measured in the temperature range 80--400 K using the 3\ensuremath{\omega} method. Thermal conductivity data for amorphous thin films of ${\mathrm{SiO}}_{2}$ are nearly identical to bulk a-${\mathrm{SiO}}_{2}$. Data for amo…
