Abstract: This invention relates to a method of preparing highly insulating GaN single crystal films in a molecular beam epitaxial growth chamber. A single crystal substrate is provided with the appropriate lattice match for the desired crystal structure of GaN. A molecular beam source of Ga and source of activated atomic and ionic nitrogen are provided within the growth chamber. The desired film is deposited by exposing the substrate to Ga and nitrogen sources in a two step growth process using a low temperature nucleation step and a high temperature growth step. The low temperature process is carried out at 100 DEG -400 DEG  C. and the high temperature process is carried out at 600 DEG -900 DEG  C. The preferred source of activated nitrogen is an electron cyclotron resonance microwave plasma.

Abstract: An apparatus and method indirectly determines the amount of outside air introduced into the ventilation system of a structure to control the indoor air quality in the structure. Test gas concentrations, preferably carbon dioxide concentrations, are measured for return air, outside air and mixed (supply) air. The flow rate of mixed air is measured. The volume of outside air introduced into the system is determined through use of the test gas concentration measurements without directly measuring the volume or flow rate of outside air. Preferably, a single sensor is utilized to measure each of the trace gas concentrations in the return air, outside air and supply air, and the various measurements sequentially multiplexed to a controller. Moreover, for calibrating the apparatus, a return air sensor is calibrated to the outside air and a mixed air sensor is calibrated to the outside air or the return air to eliminate inaccuracy due to sensor drift.

Abstract: A method for purifying flue-gases deriving from a combustion plant involves first drawing flue-gases from the plant and through a liquid volume by suction and then pressing the gases through a liquid, whereafter the purified flue-gases are discharged to the surroundings. During their passage through the liquid, the flue-gases are divided into the smallest possible flow units so as to achieve the best contact with the liquid. The method is carried out with the aid of a flue-gas purifier (5) which includes a liquid container (6), preferably a water container, which is divided into chambers (18-24). One set of chambers (18-21) forms a suction department (A) and another set of chambers (22-24) forms a pressure department (B). Walls (12, 14, 16) which form partitions between the chambers force the flue-gases to pass alternately through liquid and above the surface of the liquid. A pump (26) sucks the flue-gases through the suction department (A) and presses these gases through the pressure department (B). The walls (12, 14, 16) are provided at least partially with slots through which the flue-gases are forced to pass, therewith dividing the flue-gases into several flows, and the pump outlet (28) opens into a nozzle which finely divides the gaz and which is submerged in the liquid. As seen in the direction followed by the flue-gases, the first chamber (18) in the suction department (A) is provided with an inlet (25) for flue-gases arriving from the combustion plant, while the last chamber in the pressure department (B) is provided with an outlet (29) for the purified flue-gases.
