Resumen:
Dos institutos de investigación de Corea y Australia han desarrollado un sistema de generación de gotitas. Este sistema es especialmente útil para generar gotitas microdimensionales de un líquido orgánico o inorgánico, especialmente líquidos en fase acuosa. También es una fuente práctica de corrientes microdimensionales para reactores termoquímicos. El sistema ofrece una combinación interactiva de una boquilla de dos fluidos y una boquilla solenoide con válvula de funcionamiento cíclico. Se buscan socios en el sector de microfluídica con el fin de establecer acuerdos de licencia o cooperación técnica.

Tittle:
A Korean research institute is looking for a partner for technology transfer on a newly developed droplet generation system
Summary:
Droplet generation system was developed by two national research institutes located in Korea and Australia. The system is of particular utility in the generation of micro-dimensional droplets of an organic or inorganic liquid, especially where the liquid is an aqueous solution. It is also as a practical source of micro-dimensional streams for thermochemical reactors. The Korean research institute active in the geosciences researches hopes for a license or technical cooperation agreement.
Description:
There are a variety of reaction systems where a feed component of the reaction is delivered as a fine aerosol mixture of a solution of the component. One such context is flame spray pyrolysis (FSP), in which the fine aerosol mixture is sprayed into the flame area where thermochemical reactions take place and finally metal oxide nanoparticles are produced.

There are a number of devices for producing fine aerosol mixtures, including atomizers, mist makers and two-fluid nozzles. It is typical for these devices to have been optimized for a set of particular working parameters or conditions.

As a result, the mean droplet sizes of the aerosol mixture emitted by a given device is more or less a fixed value, depending upon those working parameters or conditions and on the specific design of the device. Moreover, the flow rate of these devices is usually substantially fixed and unable to be altered.

This lack of flexibility and adjustability in the aerosol delivery limits the utility of the reaction systems beyond the bench top or specific tailored applications. For the low cost commercial production of nanoparticles with tailored properties, a core requirement for such as adaptation is an atomizing or droplet generation system able to produce aerosol mixtures of organic or inorganic liquids of variable droplet size, yet narrow droplet size distribution, and variable flow rates.

Therefore, this Korean research institute active in the geosciences researches has newly developed droplet generation system and method with a national research institute in Australia.

The invented droplet generation system provides an interactive combination of a two-fluid nozzle and a solenoid nozzle with a cyclically operating valve.

In a first aspect, the droplet generation system provides controllable operating parameters;
- feed ratio of the liquid and gas to control the mean size of the droplets
- duty cycle (frequency of opening and the period for which it is open) to control the flow rate of the stream of droplets.

In a second aspect, the droplet generation system is directed apparatus for providing nanoparticles, in combination with a thermochemical reactor, e.g., flame spray pyrolysis.
The stream of droplets emitted by the droplet generation system is directed into a reaction chamber of the reactor for thermochemical conversion of components of the droplets whereby to produce nanoparticles of a composition determined by the liquid and gas delivered to the droplet generation system.

The institute is interested in technology transfer to overseas companies or institute in field of microfluidics with license agreement and technical cooperation agreement.
Advantages and Innovations:
The droplet generation system can:
- produce nanoparticles (5 to 30 nanometer in the particle size) by applying it to thermochemical reaction, e.g., flame spray pyrolysis;
- be used to tailor the properties of the metal oxide nanoparticles (ZnO, SiO2, TiO2, Fe2O3, LiCoO2, etc.) for various applications;
- work in a wide rate of parameters (controllable frequency and pulse width for nozzle opening, feed ratio of gas to liquid, pressure);
- operate at a greater flowrate (and thus, production rate) than other existing droplet generators.
