An apparatus and method for coating a substrate using one or more liquid raw materials, includes: at least one atomizer for atomizing the one or more liquid raw materials into droplets, charging means for electrically charging the droplets during or after the atomization and a deposition chamber in which the droplets are deposited on the substrate, the deposition chamber being provided with one or more electric fields for guiding the electrically charged droplets on the substrate. According to the invention there is a charging chamber arranged upstream of the deposition chamber and provided with charging means for electrically charging the droplets.

Apparatus and method for coating glass substrate

A process and an apparatus for coating glass by means of a method using at least one or more liquid raw materials which react essentially on at least a portion of the glass substrate forming a coating on it. At least part of the liquid raw materials is atomized to droplets with one or more two-fluid atomizer and at least a fraction of the gas used in the one or more two-fluid atomizers is electrically charged such that at least a fraction of the droplets become electrically charged during or after the atomization. According to the invention the droplets are formed into a separately created electric field.

Process and apparatus for coating glass

A method for increasing the durability of glass by a coating, according to the present invention comprises the step of coating glass with a coating comprising at least one layer whose thickness is below 5 nanometers, wherein the coating comprises a compound of at least one element.

Method for increasing the durability of glass

A method and apparatus for controlling a vapor deposition based coating process, including monitoring ultrafine particles, and adjusting at least one process parameter based on the monitoring. During at least one stage of the coating deposition process, at least one of the coating precursors includes a gas, a vapor, or an aerosol.

Process for controlling coating deposition

A coating process for coating a surface of a glass substrate in normal air pressure, in which coating process at least one liquid starting material is atomized into droplets and the formed droplets are guided towards the surface to be coated. The formed droplets are vaporized substantially close to the surface to be coated before the droplets contact the surface to be coated by bringing to the coating process the thermal energy needed for vaporizing the droplets with the glass substrate.

Method and apparatus for coating glass substrate

An optical waveguide including a core, a buffer surrounding the core, and a cladding surrounding the buffer. The core, the buffer and the cladding include silica glass. A refractive index of the buffer is substantially equal to a refractive index of pure amorphous silica glass. The buffer may reduce bubble formation during manufacturing and may facilitate splicing of the waveguide. A numerical aperture of the waveguide may be fine-tuned by adjusting a radial dimension of the buffer in order to compensate variations in the refractive index of the core.

Optical fiber structure and a method of producing thereof

The invention relates to a method and an apparatus for producing a hydrophobic surface on to a material. The invention involves directing at a surface to be structured a particle spray structuring the surface so as to structure the surface, and coating the structured surface with a hydrophobic material. According to the invention, particles larger than a determined size dare separated from the particle spray by at least one impaction nozzle, which particles are directed at the surface to be structured such that they collide with the surface to be structured, producing a structure thereon. Next, the structured surface is coated by a gas deposition method in which the structured surface is subjected to alternate surface reactions of starting materials.

Method for manufacturing an extremely hydrophobic surface

The invention relates to an apparatus for producing nanotubes, the apparatus being adapted to produce doped and/or undoped single-walled or multi-walled nanotubes, the apparatus comprising at least a thermal reactor. In accordance with the invention, the reactor is at least of the hottest part thereof and at least partly manufactured from a material that is at least partly sublimed into the thermal reactor as a result of the thermal reactor being heated, and the sublimed material at least partly participates in the growth of the nanotubes.

Device and method for producing nanotubes

The invention relates to a device and a method for producing nanoparticles, in which method starting materials for nanoparticles are mixed at least as liquid droplets and optionally also as gases and/or vapors with at least combustion gases in a premixing chamber and the mixture is separated for liquid drops larger than size d, whereafter the mixture is conducted to at least one burner, in which the combustion gases are ignited such that a heavily mixing flame is generated, in which the starting materials react and optional solvents evaporate and generate through nucleation and/or sintering and/or agglomeration particles having a diameter of 1 to 1000 micrometers.

Device and method for producing nanoparticles

A method for preparing doped oxide material, in which method substantially all the reactants forming the oxide material are brought to a vaporous reduced form in the gas phase and after this to react with each other in order to form oxide particles. The reactants in vaporous and reduced form are mixed together to a gas flow of reactants, which gas flow is further condensated fast in such a manner that substantially all the component parts of the reactants reach a supersaturated state substantially simultaneously by forming oxide particles in such a manner that there is no time to reach chemical phase balances.
