Ultrasonic nozzle

[1] The primary factors influencing the initial droplet size produced are frequency of vibration, surface tension, and viscosity of the liquid.

[2] In 1962 Dr. Robert Lang followed up on this work, essentially proving a correlation between his atomized droplet size relative to Rayleigh's liquid wavelength.

Pharmaceuticals such as Sirolimus (also called rapamycin) and paclitaxel are coated on the surface of drug eluting stents (DES) and drug-coated balloons (DCB).

Traditional methods to apply the catalyst to the proton exchange membrane typically involve screen printing or doctor-blades.

However, these methods can result in undesirable cell performance due to the tendency of the catalyst to form agglomerations resulting in non-uniform gas flow in the cell and prohibiting the catalyst from being fully exposed, running the risk that the solvent or carrier liquid may be absorbed into the membrane, both of which impeded proton exchange efficiency.

[9] ITO has excellent transparency and low sheet resistance, however it is a scarce material and prone to cracking, which does not make it a good candidate for the new flexible TCFs.

[16] In complex MEMs devices that have etched areas with high aspect ratios, it can be difficult to achieve uniform coverage along the top, side walls, and bottoms of deep grooves and trenches using spin coating techniques due to the high rate of spin needed to remove excess liquid.

In efforts to reduce the manufacturing costs of solar cell, traditionally done using the batch-based phosphoryl chloride or POCl3 method, it has been shown that using ultrasonic nozzles to lay a thin aqueous-based film onto silicon wafers can effectively be used as a diffusion process to create N-type layers with uniform surface resistance.

[19] Ultrasonic spray pyrolysis is a chemical vapor deposition (CVD) method utilized in the formation of a variety of materials in thin film or nanoparticle form.
