Abstract: The present invention concerns a method and a device for curing a thermosetting polymer. The method comprises the steps of irradiating the thermosetting polymer with microwaves at a first power level so as to heat up the thermosetting polymer by dielectric heating, and when the thermosetting polymer reaches a first predetermined temperature, irradiating the thermosetting polymer with microwaves at a second power level, substantially higher than the first power level, to further heat up the thermosetting polymer by dielectric heating. The device comprises an enclosure for receiving the thermosetting polymer, a microwave emitter for emitting microwave radiation into the enclosure, and a control unit for controlling a microwave emission power of the microwave emitter according to the abovementioned method.

Abstract: The present invention relates to a burner for a combustion chamber of a gas turbine plant. The burner includes a lance for introducing gaseous fuel into the burner. A shaft of the lance has at least one nozzle for introducing gaseous fuel into the burner. A main injection direction of the respective nozzle is oriented onto a portion of a burner wall. An introduction device for a diverting fluid is provided, which is designed for introducing a diverting fluid counteracting an impingement of the fuel flow on the burner wall.

Abstract: The present invention concerns a method for heating a polymer article reinforced with electrically conductive embedded fibers, comprising the steps of applying an outer, electrically non-conductive coating so as to cover exposed electrically conductive fibers, and irradiating the coated, fiber-reinforced thermosetting polymer article with microwaves within a predetermined frequency range so as to heat up the coated, fiber-reinforced thermosetting polymer article by dielectric heating.

Abstract: The present invention relates to a burner for a combustion chamber of a gas turbine plant, with an injection device for introducing gaseous fuel into the burner. The injection device has a body which is arranged in the burner and which has at least one nozzle for introducing gaseous fuel into the burner. The body is configured as a streamlined body which has a streamlined cross-sectional profile and which extends with a longitudinal direction transversely with respect to a main flow direction prevailing in the burner. The at least one nozzle has its outlet orifice at an trailing edge of the streamlined body.

Abstract: A sacrificial oxide etching solution of carboxylic acid and HF having a high etch selectivity for silicon oxide relative to polysilicon, metal, and nitride. The solution is useful in the fabrication of microstructures having integrated electronics on the same chip. A carboxylic acid anhydride can be added to this solution to substantially remove all free water so that the etch selectivity to metal is improved. One specific solution is formed by mixing acetic acid, acetic anhydride, and aqueous HF.
