Novel Low-energy Super hydrophilic Alloy Coatings

Hou F., Mardon I., Yang Z., Goode C., Cirrus Materials Science Ltd., NZ

Cirrus technology offers a low-voltage, non-toxic PEO super hydrophilic coating technology for application to light alloys. The novel surface finishing technology provides thin, adherent, and durable protection for alloys at low cost with an exceptionally [...]

Combining a Fluoroalkylsiloxane and Ion Implantation for Hydrophilic/Hydrophobic Patterning

Cook M.J., Johnston J.H., Leveneur J., Victoria University of Wellington, NZ

We present a novel method of producing hydrophilic/hydrophobic patterning on several different substrates using a novel two-step process. The developed process involves a simple surface functionalization with a fluoroalkylsiloxane (FAS), followed by masked ion implantation. [...]

Anti-Fouling CVD Coatings and Surface Modifications for Industrial Applications

Patterson L., Smith D., SilcoTek Corporation, US

Academia has witnessed a surge in novel coating materials and methods to control the behavior of surfaces in a variety of applications, specifically where non-stick properties (low surface energy) are desired. However, few of these [...]

An investigation into methodologies for the modification of contact angle for MX crystallography

Burton C., Prince M., Topham P., Docker D. Axford P., Orville G. Evans A., Kay J., Stuart D., Aston University, UK

This paper describes a detailed investigation into a range of surface modifications for manipulating the hydrophobicity of X-ray compatible materials for the application of surface microfluidics. With traditional microfluidics, as the scale of a fluid [...]

Durable Hydrophobic Coatings for Corrosion Protection of Metallic Materials

Koene B.E., Martin R., Goff A., Hay J., Luna Innovations, US

Luna has developed an exceptionally durable, transparent, fluid resistant coating for corrosion mitigation on selected metals and alloys. There have been many recent research and commercial efforts in the area of superhydrophobic or water repellent [...]

Evaporation induced property change and hidden cavity formation

Kim I., Texas A&M University-Corpus Christi, US

Innovative optical techniques based on nano-biophotonics such as surface plasmon resonance (SPR) imaging are developed to characterize the transport and optical properties of nanofluids in situ, real-time, and full field manner. Al2O3 nanofluids (47 nm [...]

Advanced Coating for Energy Applications

Veedu V., Pollock J., Oceanit, US

Quest for oil and gas has increased in the past few decades and the industry is in a constant change of flux to identify new oil reserves and extraction methods to recover oil and natural [...]

Reduced bacterial attachment on surface modified hydrophobic fabric surface: a possible approach for safety enhanced packaging material

Chaudhari A.A., Rangan K.K., Sudarshan T.S., Singh S.R., Pillai S.R., Alabama State University, US

In the present study, three surface modified fabrics were investigated for their bacterial attachment properties using Salmonella enterica serovar Typhimurium (gram –ve) and Staphylococcus aureus (gram+ve) bacteria. Our results indicate that surface modified fabric show [...]
