Evaluation of a Novel Self-Assembled Nanocoating in Promoting Bone On-growth and Apposition on Metal
"Loosening of metal is the leading cause of clinical failures of orthopedic surgeries. A novel coating of self-assembled monolayer of phosphonate molecules (SAMP) that chemically enhances metallic surfaces by covalently bonding to their naturally occurring oxidized surfaces has been developed.1 The …

A study of nanostructured materials toward coronary artery stenting and DNA-based biosensing
… triggered by host tissue. A plasma nanocoating (20-30 nm) has been investigated for its ability to improve patient tissue response. Nanocoatings were deposited using low temperature non-equilibrium plasma glow discharges. Nanocoatings were further modified with NH3+O2-based glows; …

Plasmonic Au nanostructures for surface-enhanced raman spectroscopy
… reported. Lastly, we will present a novel plasma nanocoating technique that overcoats SiO2/Au SERS-active nanostructures with an ultra thin polymer layer, followed by the demonstration of benefits brought by such plasma nanocoating. The properties and growth mechanisms of above mentioned plasmonic …

Experimental investigation of effects of surface roughness, wettability and boiling-time on steady state and transient CHF for nanofluids
… and uncoated. Additionally, the thickness of the nanocoating appeared to plateau after approximately 30 - 40 minutes of boiling time, and additional pre-boiling times of up to 8 hours did not have any effect on nanocoating development or CHF. The other objective of this work is to assess the …

"Reactive hard templating" : from carbon nitrides to metal nitrides
… powders could be obtained by nanocasting or nanocoating. Due to the special semi-conducting properties of the graphitic carbon nitride matrix, the nanostructured graphitic carbon nitrides show unexpected catalytic activity for the activation of benzene in Friedel-Crafts type reactions, making …

Application of raman spectroscopy in pharmaceuticals
… type II APAP was achieved by micronizing or nanocoating stable monoclinic crystallites of type I APAP. In addition, as an Appendix to the thesis, micro-Raman spectroscopy of single crystal APAP as a function of crystal orientation and of temperature was measured to provide an understanding of …

Development of novel nano-coating applied on metal stencils used in the manufacture of printed circuit boards and similar products
… for 20 g/L of PTFE when compared to Ni-Co nanocoating, which was due to the lower reduced modulus. The contact angle was also seen to improve with increase in PTFE content, which was due to the synergistic effect of PTFE and Svk/Sk ratio. Svk/Sk ratio is seen to have a higher influence on …

Molecular Dynamics Studies of Thin-Film Evaporation: The Effect of Graphene-Coated Silicon on Water Evaporation Behavior
<p>Conventional single-phase air or liquid cooling methods are insufficient to dissipate the high heat flux of next-generation electronic systems. Thin-film evaporation is one of the most promising solutions, because it takes advantage of the large amount of latent heat in the phase change process. …
