A three-dimensional (3D) printer includes an ejector and a coil wrapped at least partially around the ejector. The 3D printer also includes a power source configured to transmit voltage pulses to the coil. The 3D printer includes a computing system causing one or more drops of the liquid to be jetted out of the nozzle, and a vibrational source configured to transmit vibrational energy towards the printing material. The frequency of the vibrational energy may be dynamically modulated as a 3D object is formed by the 3D printer, and may be directly or indirectly applied to the printing material or 3D object. The vibrational source may include a piezoelectric source, ultrasonic source, a focused acoustic energy source, a laser vibrational source, or combinations thereof.

The portable insecticide dispenser is an electromechanical device. The portable insecticide dispenser vaporizes an insecticide using a method selected from the group consisting of evaporation and sublimation. The portable insecticide dispenser diffuses the vaporized insecticide into the atmosphere. The portable insecticide dispenser comprises a housing, a control circuit, and an essential oil. The housing contains the control circuit and the essential oil. The essential oil is a lipid-based substance that contains a substance known to be an insecticide. The control circuit vaporizes the essential oil such that the insecticide forms a gas phase that mixes into the atmosphere. The control circuit further mechanically diffuses the gas phase of the insecticide into the atmosphere.

The disclosed technology includes a hose nozzle assembly with apertures sized to facilitate heating groundwater based on the expected temperature of the groundwater. The hose nozzle assembly can have a handheld enclosure having a handle portion connected to a body portion, a heating chamber having a heating element configured to heat a fluid, and a spray nozzle. The spray nozzle can include a first aperture configured to provide a first spray pattern at a first flow rate corresponding to a first change in temperature of fluid flowing through the heating chamber and a second aperture configured to provide a second spray pattern at a second flow rate corresponding to a second change in temperature of fluid flowing through the heating chamber. The second flow rate can be less than the first flow rate and the second change in temperature can be greater than the first change in temperature.

The present disclosure is directed to a natural-based liquid composition for use with electronic vaporizing devices. The present disclosure is also directed to electronic vaporizing devices for using such composition. In one embodiment, the liquid compositions are water-based and are substantially free of propylene glycol and vegetable glycerin. In a preferred embodiment, the compositions may be augmented to include additives such as medicines, wellness elements, supplements, recreational elements, and natural elements performing the role of emulsifiers. The present disclosure is also directed to electronic vaporizing devices for vaporizing a natural-based liquid composition. The electronic vaporizing device may include the functionality to create specified or custom mixtures of a vaporizable material for the vaporizing thereof.

An aerosol-generating system may include a device body and a cartridge configured to be removably inserted into or connected to the device body. The device body may include a power supply and an electrical heater connected to the power supply. The cartridge contains an aerosol-forming substrate in the form of a thermoreversible gel that is a solid at room temperature.

A device and to a process which can be carried out using the device, for the production of fine particles from a liquid which solidifies upon cooling, in particular from liquid fat. The process has the advantage of producing fine particles of very small size, preferably with narrow size distribution. The device has the advantage that a solidifying liquid can be supplied at a temperature above its solidification temperature, without cooling gas leading to solidification of the liquid in the supply line, which cooling gas is used in the production of the particles.

The disclosure relates to an application device for applying an application medium onto a component, preferably for application of a coating onto a motor vehicle body component. The application device includes a print head for preferably serial and/or permanent application of the application medium, wherein the print head has: a nozzle plate, at least one nozzle in the nozzle plate in order to discharge the application medium, at least one valve element, which is movable relative to the nozzle plate, for control of the application medium discharge through the at least one nozzle, wherein the at least one movable valve element closes the at least one nozzle in a closing position and releases it in an opening position, and at least one drive for moving the at least one valve element. The application device is characterised in particular in that it includes at least one temperature control apparatus for reducing heating of the at least one drive during application of the application medium.
