Abstract:

In this study, electrically conductive coating materials composed of epoxy resin and carbon black (CB) were prepared by applying two different mixing techniques (Grinding and Mechanical Mixing). The effect of carbon black addition, ultrasonication, mixing type and surface modification of carbon black on the morphologies, electrical and mechanical properties of the composites were investigated. According to test results, Grinding Method is much more efficient and for this method, percolation concentration was found as 2 vol %. The electrical resistivity value obtained at this composition is ar

Thesis (MTech (Mechanical Engineering))--Cape Peninsula University of Technology.<br>For the last few decades, methods to improve the engine efficiency and reduce the fuel consumption of jet engines have received increased attention. One of the solutions is to increase the operating temperature in order to increase the exhaust gas temperature, resulting in an increased engine power. However, this approach can be degrading for some engine parts such as turbine blades, which are required to operate in a very hostile environment (at ≈ 90% of their melting point temperature).

Abstract:

Powder coating is an important process for many different industries. It focuses on modifying the surface properties and/or functionality of powders that the natural product does not offer. Surface modification of particles can be done by wet and dry coating methods. However, wet coating methods have become less desirable recently because of environmental concerns over the resulting waste streams and possible VOC emissions. Dry powder coating is an alternative technology avoiding the previous drawbacks, and with the advantages of having small processing time, of being environmentally friendly

Abstract:

Coating structure was mainly composed of α-fcp- and β-fcc-cobalt. Selected temperature interval for coating formation, according to XRD analysis, allowed us to form inter-metalloid compounds of CoxCry-type cobalt with chromium. Subsequent melting of a surface layer by a plasma jet resulted to doping of the coating surface by Mo atoms (compounds) from doping electrodes. It was demonstrated that essential improvement of servicing characteristics was due phase transformations induced by high-temperature plasma jet, Mo doping, redistribution of elements in the coating, and appearance of mic

Abstract:

Biofouling has been an economically and environmentally costly problem to mankind ever since they set sail. Biofouling causes frictional drag leading to slow vessel speeds, and increased fuel costs. Antifouling (AF) coatings containing biocides have been used for decades, however, since some biocides have shown undesired effects towards the environment, a non-toxic solution to combat fouling is desired. Subsequently, fouling release (FR) coatings quickly gained acceptance as a non-toxic approach to contend with biofouling. Unlike AF coatings, FR coatings not necessarily prevent settlement of o

Abstract:

High density polyethylene (HDPE) is a widely used plastic but it is also a combustible material. One way of reducing flammability is to add fillers, such as magnesium hydroxide (Mg(OH)2). However, this has a deleterious effect on the mechanical properties of composites. It has been found that one possible method of restoring mechanical properties is to modifY the filler particles with coating agents, such as stearic acid. In the present work, this idea was taken a stage further with the use of various metal stearates (e.g. magnesium stearate, calcium stearate, and zinc stearate) for modifying

Sodium alginate is a natural polymer that is soluble in water and non-cytotoxic. It is soft, permeable, not easy to stick to wounds, easy to remove, absorbs wound exudate and blood, accelerates blood clotting and facilitates tissue repair. Chitosan is also a commonly used natural substrate with a unique property of positively charged ions on the surface, which can

If the drug is over released that may cause discomfort in the affected part. On the other hand, the inflammation or bacterial infection will be induced if the drug released too low. Therefore, controlling drug release of the dressing material is an important topic in recent years. By appropriate drug delivery, the drug can be effectively applied to the affected part, and the concentration of the released drug is controlled between the toxi

Abstract:

Yes<br>Peri-implantitis remains the major impediment to the long-term use of dental implants. With increasing concern over the growth in antibiotic resistance, there is considerable interest in the preparation of antimicrobial dental implant coatings that also induce osseointegration. One such potential coating material is fluorapatite (FA). The aim of this study was to relate the antibacterial effectiveness of FA coatings against pathogens implicated in peri-implantitis to the physicochemical properties of the coating. Ordered and disordered FA coatings were produced on the under and

Abstract:

碩士<br>逢甲大學<br>自動控制工程所<br>90<br>Tongue diagnosis is generally obtained by means of observing the substance and coating of the tongue. The substance of tongue can be characterized by its color and luster. The coating of tongue can be distinguished by its color and certain textural properties. The basis of tongue diagnosis was determined by visual observation of the physicians. Therefore, environmental factors such as the difference of light sources and brightness had great influence on physicians in making good diagnostic results through the tongue. The traditional Chinese medicine is reinforced

For instance, using a computerized tongue examination system based on digital image processing techniques for the purpose of quantifying the tongue properties and building the database for patients are two important and desirable trends. In this research, one purpose is to modify the computerized tongue examination system, which provides a well calibrated tongue images capture environment. In previous research, the quantitative analysis of tongue co
