Adhesion of protective coating appliques on contaminated aluminum surfaces
The goal of this research was to develop an appliqué system to protect an aluminum surface previously coated with a RTV silicone rubber. The appliqué consisted of a poly (urethane) - based film coated with a suitable adhesive. Two adhesion problems were studied in this project: 1) adhesion to the contaminated aluminum surface, and 2) adhesion to the protective film of the appliqué.
Adhesion can occur according to several mechanisms: physical adsorption, chemical bonding, diffusion, elec

Probabilistic approach for sensor fault detection and identification (A)
Operation performance of chemical, petrochemical and biochemical processes can be enhanced considerably by an integrated advisory system that is capable of performing simultaneous tasks of (1) instrument fault detection and identification and (2) process fault detection and diagnosis. Lack of such advisory system, at present, is due to the fact that one of the assumptions of normal process operation and functional sensors is always required in existing methods that perform tasks 1 and 2. This di
Effect of transverse load on fiber bragg grating measurements (The)
The field of communications has been revolutionized by the advent of optical fiber. Optical fiber now connects most of the world carrying a vast amount of information through a very limited physical medium. To the materials engineer, optical fiber technology has stimulated interest in a new type of micro-sensor application, where the size, weight, and the ability to integrate the sensor into a material structure play a major role. Areas of interest currently include materials characterization, c

Organic-inorganic hybrid mesoporous silica materials and their application as host matrix for protei
Transparent, organic-inorganic hybrid mesoporous silica materials have been prepared successfully via the acid-catalyzed hydrolysis and cocondensation of tetramethyl orthosilicate and various organosiloxanes via the nonsurfactant templated sol-gel process. The organic groups were attached to the silica matrix via the non-hydrolyzable Si-C covalent bond and functioned as network modifier. The synthetic conditions have been systematically studied and optimized. Nitrogen adsorption and transmission
Comprehension of emotion in neurodegenerative disorders
Recent evidence indicates that the posterior corpus callosum is smaller in patients with Alzheimer's disease (AD). Conversely, it has been demonstrated that patients with frontal systems deficits also have degradation of the anterior corpus callosum. Although these investigations indicate possible morphological relationships between the corpus callosum and cortical structures in neurodegenerative disorders, the relationship between specific neuropsychological measure of cognitive functioning and
Carbon nanotube reinforced carbon nano composite fibrils by electro-spinning
Fibers of Polyacrylonitrile (PAN) are the precursor of 90% of produced carbon fibers. It is generally thought that the better the degree of molecular orientation in the original PAN fiber, the better the mechanical properties, in particular the modulus of the resultant fibers. Electro-spinning is a unique process in that it is able to produce polymer fibers having diameters ranging over seve ral orders of magnitude, from the micrometer range typical of conventional fibers down to the nanometer r
