Abstract: An energy-efficient method of controlling the composite microstructure and resulting thermoelectric (TE) properties of TE composite films. The TE composite films, which include a small amount of naturally occurring chitosan binder that is sufficient to hold TE particles together, are modified by applying uniaxial mechanical pressure at low temperatures for a short duration. The TE composite films have high electrical conductivity and low thermal conductivity, making them ideal for use into high-performance energy harvesting thermoelectric devices.

Abstract: A filtration membrane coating comprising a hydrophilic polymer, a surfactant, and one or more charged compounds, each containing one or more sulfonate functionalities and one or more linkable functionalities selected from the group consisting of amine, monochlorotriazine, and dichlorotriazine. The hydrophilic polymer and surfactant form a thin primer layer which is also superhydrophilic. The primer layer improves flux, and enables improved adhesion of the one or more charged compounds, which form a charged dye layer on top of the primer layer when enhances rejection of charged divalent ions. The coating can be applied while the membrane is packaged in its final form, such as in a spiral wound or other configuration.

Abstract: A drinking straw comprising an elongate tubular body of an insoluble material having an internal coating comprising a matrix containing an active agent dispersed within the matrix, the body sized to allow a carrier liquid to be drawn therethrough such that passage of the carrier liquid causes the matrix to release the active agent into the carrier liquid to be consumed by a drinker. The matrix comprises partially hydrolysed guar gum, possibly in combination with an acid and/or modified cellulose. The active agent includes sweetener, flavour, a nutrient and/or a pharmaceutical and optionally colour. The coating is prepared by mixing the matrix with water to form a paste or syrup and is then used to coat the inside surface of a drinking straw to a thickness of less than 1 mm. Liquid drawn through the straw dissolves or breaks down the coating, releasing the active agent into the liquid for consumption.

Abstract: A coating, a method for coating surfaces, and the coated surfaces. The method includes providing a substrate with a cleaned metal surface; contacting and coating the metal surface with an aqueous composition having a ph of from 0.5 to 7.0 and in the form of a dispersion and/or a suspension; optionally rinsing the organic coating; and drying and/or baking the organic coating, or optionally drying the organic coating and coating same with a similar or another coating composition thereto. The composition contains a complex fluoride in a quantity of 1.1 10−6 mol/l to 0.30 mol/l based on the cations. An anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt % based on the total mass of the resulting mixture is added to an anionically stabilized dispersion made of film-forming polymers and/or a suspension made of film-forming inorganic particles.
