Summary of Expertise:

Listed with other top experts in: 

Expert is an expert on removing dust or preventing dust contamination in semiconductor production and hospital environments. As part of this work, he developed a dry ice spray gun which is used to remove dust and solder flux from hybrid circuits, semiconductor devices, painted surfaces, and astronomical mirrors. This device is unique because no damage is done to even the most delicate surfaces with particles from 20 microns to less than 0.1 micron easily removed. A second device Expert developed is a "permanently" charged plastic which is used as a dust collector in many industries and can be cleaned or discarded when dirty.

microcontamination control

Interested in the digestion of complex organic compounds without the presence of oxygen, Expert has shown that it is practical to digest garbage, waste agricultural materials, and raw sewage in the same system. The digestion occurs very rapidly (about eight days) and generates natural gas and carbon dioxide that can be used as fertilizer or for softening water. The process is odorless and the system is well-suited to small cities and towns that don't want to confuse the water table.

anaerobic digestion


anaerobic sludge digestion

Expert has demonstrated that garbage and sewage can be reacted in an anaerobic atmosphere to yield useful components. This treatment method greatly reduces the need for landfills and sewage treatment plants. He is presently designing large plants for city and county use.

waste treatment

Expert is active in studying methods of destroying toxic bacteria and fungus that grow in buildings air conditioning systems before they infect the filters in hospitals, semiconductor operations, and offices. At one hospital, this problem was the reason for the spread of Legionnaires Disease.

vapor control

Expert is interested and experienced in the control of industrial-city dust by means of charged-water fog. Through laboratory and industrial studies, he and his colleagues have shown that the dust is naturally charged and that the use of oppositely charged fog is effective, uses very little water, and offers no health problems.

aerosol technology

Expert maintains that dust from industrial operations, construction, agriculture, and heavy vehicles cannot be suppressed by collectors because the dust is too widespread. He has shown that this dust is electrically charged during generation and can be suppressed by a water fog having the opposite charge. This method is far more efficient than the usual spraying techniques (which use uncharged water).

dust filtration

Expert is also working with local hospitals on bacterial control systems that operate in the ducts leading to hospital rooms. The system's goal is to remove bacteria from the air before it reaches air conditioning systems which often leads to frequent and expensive cleaning. This system will have practical air quality applications for office buildings, food operations, and semiconductor facilities.

bacterial control

Expert is knowledgeable of a variety of electro-osmosis applications in soil including the removal of salts from saline soils, soil drilling, rock grinding, and drying soil for concrete piling and foundation construction. He is currently working on a program that shows how a small voltage applied to a plow (or other implement) induces water to move to the surface of the plow and acts as a lubricant to reduce friction and thus the required tillage force. Under EPA sponsorship, Expert has been studying the application of electricity as well as certain chemicals to drill bits to improve drilling efficiency. Specifically, he is interested in finding ways to control the Zeta potential between drill bit and the medium being drilled (rock, plastics, metals, composites) to influence drill wear and penetration. This new technique offers great potential for oil well drillers, PC board manufactures, and machine shop operators.

Additional Skills and Services:
Supplier and Vendor Location and Selection

Expert has experience locating vendors of the following: ultraviolet lights; methane/CO2 separators; high voltage equipment; bacteria detectors; dust control equipment; spraying equipment; agricultural equipment (low drag plows and cultivators); and insect control systems.

He has access to the following resources: catalogs in hard copy and via the Internet; personal contacts (University of Arizona, Pima College, and the Tucson community); and the University of Arizona library system.

Other Skills and Services

Expert is working with a company to install the water vapor control system in a series of greenhouses. This is a serious problem to many commercial green house users, especially if they want to save the carbon dioxide that they have put in the greenhouse for the plants.

Expert has also worked on the recovery of fresh water from the ocean. It was shown in Japan some years ago that the rate of evaporation of water could be increased by 500% if a set of high voltage needles was near, not in, the water. The dew is fresh water; this is well known. He has also developed a system for electrostatically removing water vapor from the air; it comes out as liquid. If those systems are combined, one has an endless source of low-cost fresh water. Expert has made this work in a tabletop set up.
