The present invention provides a supply system enabling a precursor of a solid material or a precursor of a liquid material to be supplied to a latter process at no higher concentration than required and also at or above a predetermined concentration. A supply system 1 comprises: a vessel 11 for receiving a precursor material; a vessel heating unit for heating the vessel at a set temperature; a carrier gas heating unit which is disposed in an introduction line L1 and heats a carrier gas; a main measurement unit which is disposed in an outward conduction line L2 and obtains data relating to a gas of the precursor; and a carrier gas temperature control unit for controlling the temperature of the carrier gas heating unit in accordance with a measurement result of the main measurement unit.
Abstract:
To provide a method for fractionating a liquid composition, which is excellent in separability of the liquid composition. This method for fractionating a liquid composition comprises discharging, from a discharge port of a filling nozzle, a liquid composition containing a solvent and a polymer having ion exchange groups, and fractionating a predetermined amount of the liquid composition, characterized in that the temperature of the liquid composition is controlled so that the average tan δ1 of the liquid composition when discharged from the discharge port of the filling nozzle becomes to be at most 1.00.
Abstract:
The present invention mainly provides a non-contact reactor consisting of a reaction vessel having a particularly-designed size, a plurality of injection modules, an agitator, a heat exchange module, and an electrical gate valve module. Operators can inject at least one precursor solution into the reaction nanometer-scale semiconductor crystallites vessel and make the injected precursor solution reach a specific position in the reaction vessel by using the electrical gate valve to control the injection pressure of the injection modules. Moreover, the operators can further control the rotation speed of the agitator through a controller, so as to evenly and quickly mix the injected precursor solution and a specific solution pre-filled into the reaction vessel to a mixture solution; therefore, the acceleration of production rate and the enhance of production yield of the semiconductor nanocrystals are carried out.
Abstract:
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.
Abstract:
Carbon particles are disclosed, as well as methods and systems for forming the particles. In one embodiment, the system may include a receiving vessel configured to receive a liquid carbon precursor and at least one orifice at a bottom of the receiving vessel and configured to release droplets of the precursor. A cooling vessel may be positioned below the receiving vessel to receive the droplets and configured to hold a coolant for solidifying the droplets into carbon precursor particles. The method may include introducing a liquid carbon precursor into a tank having a plurality of orifices defined therein such that droplets of the precursor are released from the orifices and solidifying the droplets in a cooling vessel positioned to receive the droplets from the orifices. The method may then include carbonizing the solidified droplets to form carbon particles. The particles may be solid or hollow.
Abstract:
A thermal convection generating chip (1) includes a rotatory body (2), a thermal convection pathway (11) provided in the rotatory body (2), and a supply path (12A to 12C) that supplies a liquid to the thermal convection pathway (11). The supply path (12A to 12C) includes a liquid receiving section (121) that receives the liquid and a suction passage (122) that provides communication between the liquid receiving section (121) and the thermal convection pathway (11). The suction passage (122) has a first region (122a) extending between a midsection of the suction passage (122) and the thermal convection pathway (11), and a second region (122b) extending between the midsection and the liquid receiving section (121). The liquid in the first region (122a) is separated from the liquid in the second region (122b) through rotation of the rotatory body (2) to be supplied to the thermal convection pathway (11).
