Abstract:
Methods include applying an electric charge to a coating material that includes carbon nanotubes and a carrier, such as paint, and depositing the electrically charged coating material to a substrate. In some methods, the applying includes utilizing an electrostatic sprayer. In some methods, the substrate is isolated from ground during the depositing. In some methods, the substrate is an insulator. Some methods result in regions of carbon nanotubes that are substantially longitudinally aligned after the depositing. Coated substrates may include a coating with carbon nanotubes that are substantially longitudinally aligned and in some examples that are arranged in a zig-zag pattern. Aircraft, spacecraft, land vehicles, marine vehicles, wind turbines, and apparatuses that may be susceptible to lightning strikes or other types of electromagnetic effects and that include a coated substrate also are disclosed.
Abstract:
The invention has been based on original way of surface modification of solid substrates for efficient phosphorylated peptide preconcentration from complex peptide mixtures prior to detection based on desorption/ionization mass spectrometry. The subject of protection is the method of surface functionalization by ambient ion landing. The approach was based on electronebulization (electrospray) of solutions of organometallic compounds related to elements of 4B class of periodic table of elements, especially to zirconium, hafnium and titanium. The generated charged electrospray was dried on the fly by passing the heated compartment and focused to a surface forming a stable oxide layer there. The surface modified this way has been used for phosphopeptide enrichment from peptide mixtures prior to desorption/ionization mass spectrometry.

Abstract:
Methods and systems for coating at least a portion of a medical device (e.g., a stent structure) include providing a plurality of coating particles (e.g., monodisperse coating particles) in a defined volume. For example, the particles may be provided using one or more nozzle structures, wherein each nozzle structure includes at least one opening terminating at a dispensing end. The plurality of coating particles may be provided in the defined volume by dispensing a plurality of microdroplets having an electrical charge associated therewith from the dispensing ends of the one or more nozzle structures through use of a nonuniform electrical field between the dispensing ends and the medical device. Electrical charge is concentrated on the particle as the microdroplet evaporates. With a plurality of coating particles provided in the defined volume, such particles can be moved towards at least one surface of the medical device to form a coating thereon (e.g., using an electric field and/or a thermophoretic effect).

The invention relates to the field of chemistry and relates to a coating for wood materials, which serves as a basis for subsequent coatings. The object of the present invention is to disclose a coating, with the aid of which the conductivity of the wood materials is improved. The object is attained by a coating, in which the outer and/or inner surface of a wood material is provided with polyelectrolytes which were dissolved or are or were dispersed in water and/or an organic solvent at least up to processing, with a largely uniform distribution and wherein at least 10 g polyelectrolyte is present per square meter. The object is further attained through a method in which an aqueous solution and/or dispersion of polyelectrolytes is applied on the outer and/or inner surface of wood materials, wherein at least 10 g cationized polyelectrolyte solid is applied per square meter coated outer and/or inner surface of the wood material.

Abstract:
A method for preliminary treatment of particles of a powder in a dry surface treatment process before applying the powder particles on a surface of a substrate by utilizing an electric field created by electrodes. The Electrodes are located at opposite sides of the substrate in such a way that at least one first electrode is located at the side of the substrate to be coated, and at least one second electrode is located at the opposites side of the substrate. The particles of the powder are pre-charged before bringing them into the electric field.
