THERMAL-SPRAYED ZINC ANODES FOR CATHODIC PROTECTION OF STEEL-REINFORCED CONCRETE BRIDGES This lowering of the bond strength is caused by the dissolution of zinc at the zinc-concrete interface, particularly dissolution of the fine zinc structure that mechanically locks the coating to the concrete surface. Cross-sections of the coating from electrochemically-aged slabs were examined by scanning electron microscopy (SEM) to determine physical, chemical, and mineralogical properties of the zinc-concrete interface, and changes that may be associated with aging effects on bond strength, operation of the ICCP system, and water permeability of the coating. Bond strengths near zero, observed in the latter stages of aging for both preheated and unheated slabs, occurred when there was significant delamination of the coating from the concrete. www.corrosionsource.com /events/intercorr/techsess/papers/session4/abstracts/bullard.htm

Surface & Interface Chemistry Several research groups are involved in studies of surfaces and interfaces at the University of Oregon that examine a range of environmentally, biologically and technologically important surfaces and interfaces using a wide range of methods and techniques. In the biochemical area, most drugs act by interaction with substances at cell surfaces and surface chemistry plays an important role in the events that govern such processes. The surface of a semiconductor can have very different electronic properties than the bulk due to the molecular orbitals of the surface atoms which are left "dangling" as the bulk lattice is terminated. darkwing.uoregon.edu /~chem/surface.html   (200 words)

Jean-Marie Lehn - Autobiography Over the years, the studies in supramolecular chemistry in my laboratory at the Université Louis Pasteur in Strasbourg extended into a broad new area at the interface of chemistry with biology: self-organization processes, making use of molecular recognition to control and direct the spontaneous formation of functional architectures of high complexity. They seek to lay the chemical, molecular and supramolecular foundations on which the highly complex events of biological self-organization are built and to provide means for analyzing their mechanism as well as for acting on them. It developed from the implementation of a basic feature of supramolecular chemistry, the fact that it is by essence a dynamic chemistry with respect to the constitution of its entities. nobelprize.org /chemistry/laureates/1987/lehn-autobio.html   (2398 words)

NIH Guide: BIOMATERIALS FOR THE MICROELECTRODE-NEURAL INTERFACE (NINDS-RFI-00-03) Two differences between the implant and the neural tissue that hinder this interaction are differences in stiffness and differences in surface chemistry. In addition, the surface of an implant must be recognized biochemically by the neural tissue as a surface that is appropriate for contact. Microelectrodes offer the possibility of controlled stimulation of smaller volumes of neural tissue — on the order of one thousand to one hundred thousand times smaller than those used today — provided that the surface interaction between the microelectrode and the neural tissue is controlled. grants.nih.gov /grants/guide/notice-files/NOT-NS-00-003.html   (899 words)

Valency at Electrode Surfaces It is clearly desirable to have the ability to monitor the chemistry of the electrode surface in its electrochemical environment, since removal of the surface from the electrolyte may lead to chemical and physical changes in the surface layer. The need to analyze and understand the valency (i.e., the chemistry) at electrode surfaces has been recognized for many years, but it is only in the past 35 years that methods have become available that allow for detailed chemical information to be obtained from the surface region. The best approach to this problem is to be able to probe this chemistry in situ. www.dekker.com /sdek/254626479-67178605/abstract~db=enc~content=a713562292~words=   (379 words)

Paperloop.com - leading the pulp, paper, packaging and printing industry The problem was approached from two angles: the first objective was to retain the starch in the sheet to give superior inter- and intra-ply bonding; the second was to provide better adhesion between the coating and the substrate, by increasing the strength of the bonds at the paper/coating interface. Following an analysis of Colthrop's wet-end chemistry, National Starch advised the introduction of a waxy maize amphoteric starch, Cato 246, to the mill furnish. The amount of amphoteric starch consumed in June was down 23% on the standard level. www.paperloop.com /db_area/archive/ppi_mag/1993/9309/93090109.htm   (856 words)

Energy Citations Database (ECD) - Energy and Energy-Related Bibliographic Citations A study of the surface chemistry of lead in aqueous solutions by the technique of strain electrometry was conducted in an effort to show how the transient potentials produced, when straining lead wires, could be used to explain the known corrosion behavior of lead. All of these are known to affect the surface behavior of lead in water, and it was found that the transient potentials produced gave a qualitative picture of the reactions and reaction rates that occurred at the lead-solution interface. It was found that the transient potential produced was independent of the strain rate or rate of exposing clean metal surface to distilled water open to the atmosphere, indicating that the interfacial reactions cccurring are rather slow. www.osti.gov /energycitations/product.biblio.jsp?osti_id=4020070   (854 words)
