Abstract: The present invention relates to a method for the production of crystal layers or bulk crystals of group III nitride or of mixtures of different group III nitrides by means of precipitation, at a first temperature T1 in a first temperature range, from a group-III containing fused metal on a group-III-nitride crystal seed placed in the fused metal or on a foreign substrate placed in the fused metal, with the admixture of nitrogen in the fused metal at a pressure P. With the method a solvent additive is added to the fused metal which increases the conversion rate of group III metal to group III nitride in the fused metal. The fused metal runs through at least one temperature cycle with a first and a second process phase in which cycle the fused metal cools after the first process phase from the first temperature to a second temperature T2 below the first temperature range and at the end of the second process phase is heated from the second temperature back to a temperature within the first temperature range.

Abstract: A method of controlling a height of an encapsulant material on an inkjet printhead is provided. The method includes dispensing the encapsulant material on an outer portion of the inkjet printhead. The encapsulant material is then depressed to reduce its height on the outer portion of the inkjet printhead.

Abstract: Embodiments relate to depositing on one or more layers of materials on a fiber or fiber containing material using atomic layer deposition (ALD) to provide or enhance functionalities of the fibers or fiber containing material. A layer of material is deposited coated on the fibers or fiber containing textile by causing the relative movement between a fiber or the fiber containing textile and a source injector.

By increasing the volume of the material, the material is subject to compressive stress. The compressive stress renders the fibers or the fiber containing material more rigid, stronger and more resistant against bending force, impact or tensile force.
