*  Surface Composition of Copper Nickel Alloys
The surface composition of alloys is of great importance in determining their chemical and catalytic properties. In this paper, a presentation is given of the application of Auger electron spectroscopy and photoemission spectroscopy to the study of the surface composition of copper-nickel alloys. An enrichment of copper in the surface region is observed for annealed surfaces. The effects of sputtering and chemisorption on the surface composition are also treated. By applying a nondestructive technique like photoemission, it has been demonstrated for the first time that there is at least one oscillation in the depth profile of the composition. This observation cannot be explained readily by the regular solution theory which, for instance, correctly predicts the copper enrichment at the surface. ...

It is well known that the effectiveness of a trailing-edge control surface can be substantially diminished due to the elastic twist of an airfoil or wing. This aeroelastic phenomenon is known as control surface reversal when the lift or roll rate vanishes at a sufficiently large ratio of flow dynamic pressure to wing stiffness. However, a leading-edge control surface can be used to counteract control surface reversal, and indeed, in principle, a leading-edge control surface may entirely cancel the tendency of the trailing-edge control surface to undergo reversal. Moreover, analysis shows that by using a simple control strategy one can use a combination of leading- and trailing-edge control surface rotations to maintain lift and roll effectiveness and minimize control surface rotations. The beneficial effects of leading-edge control surfaces on control ...

Ubiquinone and plastoquinone are two of the main electron and proton shuttle molecules in biological systems, and monogalactosyldiacylglycerol (MGDG) is the most abundant lipid in the thylakoid membrane of chloroplasts. Saturated MGDG, ubiquinone-10 (UQ) and MGDG:UQ mixed monolayers at the air/water interface have been studied using surface pressure-area isotherms and Brewster Angle Microscopy. Moreover, the transferred Langmuir-Blodgett films have been observed by Atomic Force Microscopy. The results show that MGDG:UQ mixtures present more fluid phase than pure MGDG, indicating a higher order degree for the later. It is also observed an important influence of UQ on the MGDG matrix before UQ collapse pressure and a low influence after this event, due to UQ expulsion from the MGDG matrix. This expulsion leads to a similar remaining UQ content for all the tested mixtures, indicating a limiting content of this molecule in the MGDG matrix at high surface pressures. The ...

*  Biofilms] Re: Surface energy - meaning?
Surface energy is a measure of disruption of chemical bonds that occurs when a surface is created. Most of the hydrophobic surfaces are known to show low surface energy values. It is also well known that hydrophobicity has a role in cell attachment to the surface and biofilm formation. As the biofilm progresses the adhesion is higher and chemical bonding is more hence lower the surface energy. Few studies were carried out on adhesion of biological systems such as proteins, microbes, algae and invertebrates. They all show minimal long-term adhesion associated with surfaces having low energy surfaces. However, all surfaces rapidly become modified on immersion in natural waters through the adsorption of conditioning films, which may influence subsequent adhesive events associated with the permanent attachment of organisms. The results show that ...

*  Patent US5769540 - Non-contact optical techniques for measuring surface conditions - Google Patents
Thermal, optical, physical and chemical characteristics of a substrate (11) surface are determined with non-contact optical techniques that include illuminating (23) the surface with radiation having a ripple intensity characteristic (51), and then measuring the combined intensities (53) of that radiation after modification by the substrate surface and radiation emitted from the surface. Precise determinations of emissivity, reflectivity, temperature, changing surface composition, the existence of any layer formed on the surface and its thickness are all possible from this measurement. They may be made in situ and substantially in real time, thus allowing the measurement to control (39, 41) various processes of treating a substrate surface. This has significant applicability to semiconductor wafer processing and metal processing.

Here, we report on a special tribometer built to operate inside an environmental scanning electron microscope enabling charge-free imaging of non-conductive and/or hydrated materials. The device is intended to be used for simultaneous testing and in situ visual inspection of biological and biomimetic patterned surfaces during contact formation, pulling-off, peeling, and shearing modeling the behavior of biological microstructured attachment systems in nature. To demonstrate its performance, a simple array of hexagonal elastomer micropillars is tested. The results obtained show that direct link between precise data on the contact forces and images of the contact elements deformed by these forces indeed allows getting an insight into how contact surface patterns function when in contact. ...

*  An overview of biofunctionalization of metals in Japan | Journal of The Royal Society Interface
The technological evolution of ceramics and polymers during the last three decades makes it possible to apply these materials to medical devices; in fact, many metal devices have been replaced with those made of ceramics and polymers. In spite of this event, over 70 per cent of implant devices still consist of metals because of their high strength, toughness and durability. At present, it is difficult to replace the metals in medical devices with ceramics or polymers.. A disadvantage of using metals as biomaterials is that they are typically artificial materials and have no biofunction. To add biofunction to metals, surface modification is necessary because biofunction cannot be added during manufacturing processes such as melting, casting, forging and heat treatment. Surface modification is a process that changes a material's surface composition, structure and morphology, leaving the bulk mechanical properties intact. With ...

A method is disclosed for attaching a bonding pad to the ohmic contact of a diode while reducing the complexity of the photolithography steps. The method includes the steps of forming a blanket passivation layer over the epitaxial layers and ohmic contacts of a diode, depositing a photoresist layer over the blanket passivation layer, opening a via through the photoresist above the ohmic contacts and on the blanket passivation layer, removing the portion of the blanket passivation layer defined by the via to expose the surface of the ohmic contact, depositing a metal layer on the remaining photoresist, and on the exposed portion of the ohmic contact defined by the via, and removing the remaining photoresist to thereby concurrently remove any metal on the photoresist and to thereby establish a metal bond pad on the ohmic contact in the via.

*  Effect of the mineral filler on the surface properties of co-ground polymeric composites - oatao
This study presents results on the influence of the filler nature on the surface properties of polymeric composites produced by co-grinding in a tumbing ball mill. The polymer used in the study was poly(vinyl acetate) which is a model material, while two mineral fillers were tested: calcium carbonate and silica. The variations of the surface properties of the separately ground and co-groundmaterials were studied for different grinding times, using the sessile drop method, and the properties were compared to those of matrix _ filler blends. The different components of the surface energy were determined and the Van Oss decomposition was used. Grinding generates great changes of particle surface and especially of the Lewis acid _ base energy and these changes depend on the filler nature. Thus, particle agglomeration may be due to an electronic deficit at the particle ...

*  Unraveling Surface Properties of Cytochrome c@Au Nanoparticle Bionanoprobes
Bionanoprobes were created using cytochromes c isolated from horse heart (HCc) or yeast (YCc); and citrate-stabilized AuNPs. The two cytochromes c generated bionanoprobes with remarkably distinct surface properties. The combination of spectrophotometric pH-titrations and circular dichroism spectroscopy provided information on the protein layer of the bionanoprobes, revealing distinct protonation patterns for the two systems as reflected by its pH-induced aggregation. The YCc bionanoprobe revealed changes in the secondary structure of its protein layer that were practically absent in the protein layer of the HCc bionanoprobes. Atomic force microscopy and dynamic light scattering and determination of -potencial, provided insights on the layer structure and surface coverage and potential. These techniques confirmed a thick protein layer for the YCc bionanoprobe of ca. 4 nm whereas the HCc bionanoprobe presented a protein layer with ca. 2 nm that can be removed ...
