Victor Chang's Problem Solving Experience:

1. It was found that silicon dendrites within Aluminum-silicon alloys possess certain semiconducting properties. Could these dendrites be used as semiconductor in certain cases
2. We patented the conceptual design of a new type of internal combustion engine. The engine's main advantage is its simplicity and low greenhouse gas emissions
3. We developed a set of sensors for remote monitoring of oil wells activated by rocker. The sensors were the dynagrafic chart, the measurement of water content in the crude oil, the determination of fluid flow in the pipe, the detection of leakage to the wellhead. This system, as a whole, could save losses and pollution due to many breakdowns in oil wells.
4. A sensor was developed for the online measurement of the viscosity of non-Newtonian fluids (emulsions).
5. A mechanical method was developed for measuring the flow in Newtonian and non-Newtonian (emulsions) fluids.
6. We found a method for relating the heat transfer during solidification of a metal and the microstructure obtained. This allows predicting the characteristics of an alloy according to the conditions of solidification.
7. We studied both, theoretical and experimentally, the differences in operation between two water heaters powered by solar energy. The study led to elucidate the differences in efficiency between models.
8. We studied the separation of iron oxides and aluminum oxides using the technique of high gradient magnetic separation. Relationships were found between the operating parameters and the efficiency of separation. The interest of this study is the possibility of obtaining high content aluminum ore minerals from low content ones.
9. It was found that the cuprous oxide possesses simultaneous thermoelectrical and piezoelectric properties. These properties can be used for making sensors and other applications.
10. We developed a motion platform for 12 an 16 seats to use in motion ride simulators with 3 Degrees of freedom (3 DOF) (2 Patents pending).
    Also developed the complete ride system, including motion control, stereoscopic (3D) projection, boarding mechanism, etc.
11. We developed an ejector-compressor cooling system, activated by solar energy. This system would allow obtaining cooling from solar energy.
12. It was shown that the microstructure of metal alloys can be used as selective solar absorbers. This would enable the manufacture of more efficient solar collecting surfaces at lower costs.
13. We developed a magnetic sensor for measuring the water content in crude oil. Also developed a capacitance sensor for measuring the same parameter.
14. We demonstrated, at laboratory level, the possibility of extracting oil by using an hybrid pump system. This pumping system will permit the extraction of crude oil in declined wells.
15. It was found that the microstructure of aluminum-copper chromium alloys can be used as catalyst in the oxidation of carbon monoxide. This would allow a catalyst for automotive exhaust gases which would be cheaper and resistant to lead poisoning.
16. It was developed a mathematical model for predicting solidification in continuous casting of metals. This model allows continuous casting mills, control the process with very few elements and avoiding losses due to breakage of ingots.
17. A composite material and a method were developed to measure the deformation of solid bodies. This allows the study of the deformation of mechanical parts of any size.
