Journal of the American Chemical Society, 2007
This paper introduces a fundamentally new concept in adsorbents, whereby the sorption of an aqueous solute by a cross-linked polymer is controlled by a gel to liquid-crystalline phase transition. To demonstrate proof of principle, a bilayer forming surfactant, N,N-dioctadecyl,N,N-dimethylammonium bromide (DODAB) has been immobilized onto a cation ...

The article reports on the development of extremely water-repellent textured surfaces inspired by the microscopic structure of the lotus flower, and other surfaces which have the opposite property, known as superhydrophilicity. The possibility of engineering products which combine the two features, in order to control the microscopic flow of fluids, is

Proteinic fibers, capable of converting incident light to self-cleaning power to decompose its contamination and harmful microorganisms in a process of photocatalytic purification, are very interesting materials for various applications. In this contribution, self-cleaning keratin fibers have been realized following a bottom-up nanotechnology approach.

Nanocrystalline titanium dioxide has been prepared under ambient pressure and at temperatures close to or approaching room temperature using hydrolysis of titanium tetraisopropoxide in an acidic aqueous solution. A transparent thin layer of nanocrystalline titania has been produced on cotton textiles by a dip-pad–dry-cure process.

Directional Self-Cleaning Superoleophobic Surface
Langmuir, 2012In this work, we report the creation of a grooved surface comprising 3 μm grooves (height ~4 μm) separated by 3 μm from each other on a silicon wafer by photolithography. The grooved surface was then modified chemically with a fluorosilane layer (FOTS).

Self-cleaning glass with a coated external surface exhibits both photocatalytic and photo-induced superhydrophilic properties. Such properties provide the conditions for the decomposition of organic contaminants and washing-off of inorganic ones by rainwater flowing down in the form of a thin film.

Review of Scientific Instruments, 1993
A contamination-free Langmuir probe of novel design is described. Surface contaminants, which lead to erroneous evaluation of plasma parameters by distortion of the probe’s current-voltage characteristic, are removed by the indirect heating of the probe tip with separate heating elements running parallel to the probe wire in multibore alumina tubing ...

Journal of the American Leather Chemists Association
This work evaluated the use of polycarboxylic acids as chemical binders to immobilize TiO2 to produce “crust” vegetable-tanned leather with self-cleaning properties. A methodology was developed with immersion of leather samples in a solution of polycarboxylic acids, followed by curing of the binder.
