Super-Hydrophobic Nano-Composite Films

Helmrich F., Integrated Surface Technologies, US

An improved super-hydrophobic nano-composite film protects cell phones and other portable electronics from accidental exposure to water or other liquids. The printed circuit boards, the connectors and the batteries are coated. Perfect electrical contact is [...]

Nano-structured Organically Modified Silica Thin Films for Functional Surfaces

Bayindir M., Yildirim A., Budunoglu H., Yaman M., Deniz H., Guler M.O., Bilkent University, TR

Organically modified silica (ormosil) nano-composites are unique materials that offer best of the both of organic polymers and inorganics, like mechanical flexibility together with good chemical durability [1]. Nano-porosity adds these hybrid materials extra-functionality (e.g., [...]

High resolution imaging of biological materials using hydrophobic carbon nanotube AFM probes

Lee J-H., Najeeb C.K., Chang J., Kang W-S, Nam G-H, Kim J.H., Ajou University, KR

Carbon nanotube (CNT) tipped atomic force microscope (AFM) probes have shown a significant potential for obtaining high resolution imaging of nanostructure and biological materials. In this work, we report a simple method to fabricate single-walled [...]

A Hydrophobicity Controlled Nanofluidic Pump

Liu H., Dharmatilleke S., Tay A.A.O., Institute of Materials Research and Engineering, SG

interfacial energies in the system. Many methods for modulation of surface tension to manipulate fluids in micro or nano scale have been studied and reported, including the mechanical (surface roughness effect), chemical (electrochemical effect), opto- [...]

Reliability of Self-assembled Hydropobic Coatings: Chemical Resistance and Mechanical Durability

Kobrin B., Zhang T., Grimes M.T., Chong K., Nowak R., Chinn J., Applied Microstructures, US

We report on hydrophobic self-assembled monolayers (SAM) with an improved chemical and mechanical stability on both Al and Si substrates. These improvements are obtained using a relatively new molecular vapor deposition method - MVDTM, which [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

An Effective Passive Micromixer Employing Herringbone Structure

Kung C-F, Chen C-F, Chu C-C, Tseng F-G, IAM, National Taiwan University, TW

This paper proposes a high efficient micro mixer, passively employing surface tension force as driving power and Herringbone structures as vortex generator for fluid mixing. The fluidic channel was designed without sidewall and confined with [...]
