Coatings: Superhydrophilic Coating Induced Temporary Conductivity for Low-Cost Coating and Patterning of Insulating Surfaces (Adv. Funct. Mater. 48/2016)

Coating Selection and Important Properties of Coatings for Concrete

Reasons for Coating Concrete Some reasons for coating concrete are unique to the structures in question while other reasons apply to coating any substructure. The major reasons for coating concrete include • enhancing appearance with respect to colour, gloss, or texture for architectural purposes; • reducing moisture permeability, which can otherwise lead to freeze-thaw damage, rebar corrosion,...

Coating and Patterning Functional Materials for Large Area Electrofluidic Arrays

Industrialization of electrofluidic devices requires both high performance coating laminates and efficient material utilization on large area substrates. Here we show that screen printing can be effectively used to provide homogeneous pin-hole free patterned amorphous fluoropolymer dielectric layers to provide both the insulating and fluidic reversibility required for devices. Subsequently, we ...

Temporary Single-Cell Coating for Bioprocessing with a Cationic Polymer

Temporary single-cell coating is a useful tool for cell processing, allowing manipulation of cells to prevent cell attachment and agglomeration, before re-establishing normal cell function. In this work, a speckled coating method using a known polycation [poly(l-lysine), PLL] is described to induce cell surface electrostatic charges on three different cell types, namely, two bone cancer cell li...

Selective dip-coating of chemically micropatterned surfaces

We characterize the selective deposition of liquid microstructures on chemically heterogeneous surfaces by means of dip coating processes. The maximum deposited film thickness depends critically on the speed of withdrawal as well as the pattern size, geometry, and angular orientation. For vertically oriented hydrophilic strips, we derive a hydrodynamic scaling relation for the deposited film th...
