Average bubble diameters of 0.9 mm are possible nowadays, using special polyurethane (PUR) or special recently developed EPDM membranes. [3] Fine bubble diffusers have largely replaced coarse bubble diffusers and mechanical aerators in most of the developed world and in much of the developing world. The exception would be in secondary treatment ...
A nanobubble is a small sub-micrometer gas-containing cavity, or bubble, in aqueous solutions with unique properties caused by high internal pressure, small size and surface charge.
Ozone micro/nano-bubble technology improves the disinfectant capacity of ozone. [ 2 ] Ozone is a strong oxidizing agent widely used in the treatment of printing and dyeing wastewater, [ 3 ] and coal chemical wastewater. [ 4 ]
Plasma processing achieves this effect through a combination of reduction of metal oxides, ultra-fine surface cleaning from organic contaminants, modification of the surface topography and deposition of functional chemical groups. Importantly, the plasma activation can be performed at atmospheric pressure using air or typical industrial gases ...
The composition of the bubble shell and filling material determine important design features such as buoyancy, crush strength, thermal conductivity, and acoustic properties. They are used in medical diagnostics as a contrast agent for ultrasound imaging . [ 4 ]
The company was founded in 1992 by Darren Saravis, a known figure in the medical device industry. Saravis has a background in design and engineering and has developed various projects for the company, including the BDR-19 Critical-Care Ventilator that received emergency use authorization during the Covid-19 pandemic in 2020.

The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development.
