A system for fluid transport is provided where a quantity of fluid is held in a reservoir. A droplet generator is employed to generate droplets from the fluid, for example a nozzle-based system or a nozzleless system such as an acoustic ejection system. A generated droplet has a trajectory whereby it arrives at a target. A circuit is used to modify one or more characteristics of the generated droplet in a way which increases the likelihood that the droplet will not splash or bounce when it arrives at the target. The circuit may in different embodiments control the speed of the droplet or the Weber number of the droplet. The circuit may create an electric field in an area of space where the droplet passes. The circuit may charge the droplet by causing it to contact ions.

The present disclosure provides a device for controlling the shape of an aerosol particle condensation growth flow field through an electromagnetic field. The device includes an aerosol growth device and a power supply. The aerosol growth device includes a porous medium, magnetic rubber and an electromagnet group. The magnetic rubber is sleeved in an inner cavity of the electromagnet group, and the porous medium is sleeved in an inner cavity of the magnetic rubber. The magnetic rubber is clung or clings to the porous medium, and the power supply is connected with the electromagnet group. The present disclosure also provides a method for controlling the shape of the aerosol particle condensation growth flow field through the electromagnetic field.

There is provided an electrostatic film formation device including a powder feeder feeding powder, a substrate on which a powder film is to be formed from the powder, and a DC power supply applying voltage to the powder feeder and the substrate. The DC power supply applies the voltage to draw the powder from the powder feeder to the substrate with electrostatic force. The electrostatic film formation device further includes a masking member disposed between the powder feeder and the substrate. The masking member is formed with a passing port allowing the powder to pass from the powder feeder to the substrate. The masking member is disposed in the state where the masking member is not in contact with the powder film to be formed.

A fluidized bed spray drying system for drying liquid into powder including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. A drying gas inlet is provided in the powder collection chamber and a drying gas outlet is provided at an upper end of the drying chamber. A plurality of cylindrical filter elements at the upper end of the drying chamber are in communication with the exhaust gas outlet for filtering drying gas borne powder from drying gas exiting the drying chamber.

An apparatus for producing a fibrous material. The apparatus uses a first material source within which is disposed a first material and a second material source enclosing a second material. The first and second materials to be electrospun. A first and second tip attached to an end of the first and second material sources, with a collector spaced apart from the first and second material sources. A first and second electric field generator each produces a first and second signal each in the form of a sine wave and having a first and second frequency. The fibers are formed from the first and second materials as extracted from the respective first and second tips responsive to a first and second electric field generated between the respective first and second tips and the collector.

Various exemplary illustrations of an electrode assembly for an electrostatic atomizer, for example for a rotation atomizer, and exemplary methods of making and/or using the same, are disclosed. An exemplary electrode assembly may not include an electrode holder arrangement for holding at least one electrode creating an electrostatic field about a symmetrical axis, wherein there is dielectric material for influencing a discharge current component extending in the direction of the symmetrical axis.

A voltage application device according to the present disclosure includes a voltage application circuit and a control circuit. The control circuit causes the voltage application circuit to alternately repeat a first mode and a second mode. The first mode is a mode that raises a voltage while time elapses, and generates a discharge current by promoting corona discharge to dielectric breakdown. The second mode is a mode that lowers the voltage to cut off the discharge current by causing a load to be in an overload state against the voltage application circuit. This can suppress an amount of ozone generated, while increasing an amount of radicals produced.

Provided are a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method and a large-area, three-dimensional graphene transparent electrode prepared therefrom. More particularly, the present invention is related to a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method, which may easily prepare a large-area graphene transparent electrode having high transparency and conductivity through an electrospray process and may obtain effects, which may not be realized in a two-dimensional transparent electrode prepared by a typical method such as CVD, due to a three-dimensional stack structure in which graphene is arranged perpendicular to a substrate, and a large-area, three-dimensional graphene transparent electrode prepared therefrom.
