Mussels (Mytilus edulis) are economically important in their role as an aquaculture species and also with regard to marine biofouling. They attach tenaciously to a wide variety of submerged surfaces by virtue of collagenous attachment threads termed 'byssi'. The aim of this study was to characterize the spreading of the byssal attachment plaque, which mediates attachment to the surface, on a ra...

A photocontrolled molecular shuttle SAM based on an alpha-cyclodextrin (alpha-CD)/azobenzene inclusion complex on rough gold surfaces is fabricated, which can reversibly switch the surface wettability by transferring external energy (light) to molecular mechanical motion.

A benzoquinone monolayer-functionalized electrode reveals electrochemically or chemically controlled wettability; the hydrophobicity of the hydroquinone-modified surface is enhanced by the presence of a donor-acceptor complex with N,N'-dimethyl-4,4'-bipyridinium as the pi-electron acceptor.

Careful preparation and cleaning of various types of components is indispensable prior to their surface treatment or final assembly. Various surface treatment operations that require such care include vacuum deposition, electrodeposition, electroless deposition, various dip coatings, etc. Surface preparation is essential for achieving good and firmly adhered coatings. Trace of residual surface ...

The solid particles are adsorbed at interfaces and form self-assembled structures when the particles have suitable wettability to both liquids. Here, we show theoretically how the microstructure on the particle surface affects their adsorption properties. The physical properties of the interface adsorbing a particle will be described by taking into account the surface roughness due to the micro...

A smart surface with wettability that can be switched between superhydrophobicity and superhydrophilicity has been realized on a transparent and conductive SnO2 nanorod film by the alternation of UV-irradiation and dark storage.

Horizontal cylinders floating on liquid surfaces are mundanely observed, whose examples include the legs of aquatic arthropods and floating larvae, twigs and hairs. We study the force and energy required to lift the cylinder clear from the water surface, to evaluate the role of wettability, especially superhydrophobicity, in the adhesion of floating cylinders. We find that a drastic degree of e...

We present a simple method to spatially pattern the surface properties of microfluidic devices using flow confinement. Our technique allows surface patterning with micron-scale resolution. To demonstrate its effectiveness, we use it to pattern wettability to form W/O/W and O/W/O double emulsions.

We developed a method for the in situ synthesis of an oligoamide coating on gold. The resultant surface chemical composition, wettability, and chemical nature were comparable to aromatic polyamide films used as reverse osmosis membranes. Hence, the oligoamide wafer may be used in adsorption/fouling studies as a surface mimetic of reverse osmosis membranes.
