Ceramic coated carbon steel coupons were corrosion tested in water with dissolved salts to simulate exposure to evaporation concentrated groundwater in an underground nuclear repository. Metallography revealed no corrosion at the ceramic metal interface of dense coatings, even though electrical measurements demonstrated that the coatings were slightly porous. Experimental results and a model to...

The problem emerging from particle coating is how to manufacture particles with just enough material deposited to achive the desired result [1]. Especially in case of functional coatings, the uniformity of coating thickness over the entire particle surface plays an important role. In our study the performance of two bottom spray coaters and the effect of the particle motion on the coating unifo...

Numerous spray machines are used to apply pesticides for the control of human disease vectors, such as mosquitoes and flies, and the selection and setup of these machines significantly affects the level of control achieved during an application. The droplet spectra produced by 9 different ultra-low-volume sprayers with oil- and water-based spray solutions were evaluated along with 2 thermal fog...

DEDICATION To my parents, thank you for always encouraging me to explore the world. v ACKNOWLEDGEMENTS I would to thank my advisor, Julie M. Goddard, for her guidance and support throughout my degree. Thanks are also due to the entire Bioengineering group, especially Luis Bastarrachea for his mentorship and advice. I would also like to extend my gratitude to my committee members, Amanda Kinchla...

rapid thermal processing (rtp) has become a key technology for semiconductor device manufacturing in a variety of applications, such as thermal oxidation, annealing, and thin-film growth. hence, understanding the radiative properties of silicon and other relevant materials is essential for the analysis of the thermal transport processes. we have analyzed and calculated the spectral, directional...

It has been reported by previous research work that in plasma spray process hydroxyapatite decomposes into some amorphous phases due to rapid cooling of the coated substrate during the coating process, which causes instability of coated implant. Post coating heat treatment has been expected to minimize these phases and also enhance the long term reliability of hydroxyapatite coatings on metal s...

This work presents a novel coating technique to manufacture ceramic superhydrophobic coatings rapidly and economically. A rare earth oxide (REO) was selected as the coating material due to its hydrophobic nature, chemical inertness, high temperature stability, and good mechanical properties, and deposited on stainless steel substrates by solution precursor plasma spray (SPPS). The effects of va...

L-menthol stimulates cutaneous thermoreceptors and induces cool sensations improving thermal comfort, but has been linked to heat storage responses; this could increase risk of heat illness during self-paced exercise in the heat. Therefore, L-menthol application could lead to a discrepancy between behavioral and autonomic thermoregulatory drivers. Eight male participants volunteered. They were ...

Bone implants must be biocompatible and are usually built to promote osseointegration, e.g. by application of plasma spray calcium phosphate (CaP) coating. The risk of infection and biofilm formation on implant surfaces is a well-known problem. The combination of electrochemically deposited CaP coating with antibiotics may offer significant benefits. Here, we demonstrate an innovative in situ e...
