Abstract: The invention relates to a process for connecting glass substrates which allows glass substrates to be aligned in a site-specific manner and to subsequently be connected to one another, and to the site-specifically aligned and interconnected glass substrates. Generally, the process relates to connecting glass substrates to one another, optionally also without site-specific alignment. The interconnected glass substrates obtainable by processes according to the invention are characterized by a firm bond with one another, which is preferably formed by solidified glass solder that is in form-fitting engagement with the glass substrates. Therein, recesses, which are preformed in the glass substrate, with glass solder are used for aligning and optionally for connecting the glass substrates.

Abstract: The invention provides a process for producing plastic parts, each of which has at least one glass insert which is connected to the plastic part along a connecting region, and the glass insert is free of plastic in the region encompassed by the connecting region and forms a glass window. The connecting region of the glass insert is preferably circumferentially closed. The glass window can have through-holes or preferably recesses extending only over a portion of the thickness of the glass window and having microstructures.

Abstract: The invention relates to a carrier which is suitable for the cultivation of cells and is preferably a plate-shaped carrier, e.g. made of glass, silicon or plastic or a combination thereof, in which carrier at least one first recess is formed which extends over a first thickness portion of the carrier, wherein an array of second recesses extends from the first recess into a second thickness portion of the carrier adjacent to the first thickness portion. The first thickness portion may have a thickness of a few micrometres to several centimetres. The second recesses, which extend from a first recess into the second thickness portion and each form a second array, form cups which are suitable for receiving cells and/or synthetic particles, e.g. made of plastic or glass.

The non-conductive carrier material having an additive, which is configured to subsequently form a catalytically active species in an electroless metallization bath by irradiation with the laser radiation. The method includes: forming the conductive structure being by irradiation using pulsed laser radiation having a pulse duration of less than 100 picoseconds and subsequent electroless metallization. A pulse repetition rate is set such that consecutive pulses of the pulsed laser radiation in an area of the additive to be activated or an additive area are diverted mutually overlapping onto the additive or the additive area.

Abstract: A process for the production of a glass-plastic connection which is form-fitting, and to a form-fitting composite between glass and plastic which is obtainable by the process. The process and the glass-plastic composite are characterized in that a glass, which in particular is planar, neither during the process nor in the glass-plastic composite is subjected to a mechanical load which could lead to cracks, e.g. microcracks. Accordingly, in the composite, the glass is connected to a plastic in a stress-free manner The composite of glass with plastic is especially gas-proof and/or liquid-proof.

Abstract: A method for producing an electrically conductive structure, e.g., a conducting track, on a non-conductive substrate material, having an additive (1) having at least one metal compound. The substrate material may be irradiated using a laser to selectively activate the metal compounds, for example inorganic metal compounds, contained in the additive (1). The metal seeds formed by the activation are then metallized to create the electrically conductive structure on the substrate material. Because the additive (1) has a preferably full-surface coating before the additive is introduced into the substrate material, such that the additive (1) is reduced and the coating is oxidized by the laser activation, the reaction partners necessary for the required chemical reaction with the additive (1) are provided by the coating. Because of the thereby significantly reduced interaction with the substrate material, the limitation to certain plastics or plastic groups also is lifted.
