The present invention allows measurement of a precise amount of gas by preventing sudden flow rate fluctuations of gas. A gas supply system 1a for a mixing-discharging apparatus 90 to mix gas and paste material includes a regulator 2 adapted to control pressure of gas supplied to the mixing-discharging apparatus, a flow meter 3 adapted to measure flow rate of the gas, a gas storage portion 4 adapted to store the gas, and a valve 5 adapted to open and close a gas introduction path 11 to the mixing-discharging apparatus 90. The flow meter 3 is placed in front of the gas storage portion 4 and behind the regulator 2 with respect to a flow of the gas.

A hybrid dehydrogenation reaction system includes: an acid aqueous solution tank having an acid aqueous solution; an exothermic dehydrogenation reactor including a chemical hydride of a solid state and receiving the acid aqueous solution from the acid aqueous solution tank for an exothermic dehydrogenation reaction of the chemical hydride and the acid aqueous solution to generate hydrogen; an LOHC tank including a liquid organic hydrogen carrier (LOHC); and an endothermic dehydrogenation reactor receiving the liquid organic hydrogen carrier from the LOHC tank and generating hydrogen through an endothermic dehydrogenation reaction of the liquid organic hydrogen carrier by using heat generated from the exothermic dehydrogenation reactor.

The present invention is related to a system and method for controlled manufacturing of mono-disperse microbubbles. According to the invention, the mono-disperse nature of the collection of generated microbubbles can be improved by releasing the pressurized gaseous medium used in the system using release valve units. This further allows the system to be embodied as a portable system. In turn, the operator of an ultrasound imaging apparatus may use the system according to the invention to generate microbubbles on a patient-by-patient basis.

The present invention provides a filling nozzle obtained by using a resin selected from a cycloolefin polymer and a cycloolefin copolymer, or a filling nozzle including a tubular passage for supplying a pharmaceutical solution, and a filling port disposed at a lower end of the tubular passage, in which the tubular passage and the filling port have a circular peripheral cross-section, and an inner diameter of the passage of the filling port is larger than an inner diameter of the tubular passage disposed on an upstream side.

Systems and methods for delivering active ingredients, such as pharmaceutically active ingredients, to substrates are described herein. The active ingredients are delivered as fluids to a fluiddispensing device for the creation of one or more drops for deposition onto substrates such as for the creation of microdoses. The invention further includes microdoses made by such processes.
