The most widely accepted theory regarding the role of aluminum in pinhole formation attributed it to the reaction between aluminum dissolved in iron with moisture from the sand mold to produce
aluminum oxide and hydrogen; hydrogen being absorbed by the liquid iron.
In the MFC modified to produce
hydrogen, the cathode is kept free of oxygen.
Many rubber-producing plants produce
natural rubber, although few do so in high yields or high molecular weights.
The first is an industrial process that may make ethanol far cheaper to produce
than ever before, with the potential of making this much-maligned--and over-subsidized--biofuel economically competitive with gasoline.
6-m wide machine, produces
150,000 metric tons/year of UPM Finesse 220, a coated (silk) grade.
The scientists also found that Colorado potato beetles reared on potato plants that produce
large amounts of a protease inhibitor make enzymes that are insensitive to the inhibitor.
Some penicilliums can produce
unsavory mycotoxins like ochratoxin, but many others seem to be benign.
Desktop technology is used to edit photographs by only 11 percent, to create halftones and color separations by eight percent, to edit video tapes by four percent and to produce
interactive media programs by another four percent (chart 1).
Despite the element's promise as a fuel, a dearth of economical and Earth-friendly ways to produce
pure hydrogen is slowing adoption of hydrogen-powered technologies.
1943--Keith Millis, a 28year-old metallurgist working at INCO searching for a replacement to chrome due to interrupted supply, discovers that magnesium alloy in molten iron produces
a spheroidal graphite structure.
Theorists had predicted that if a nucleus could be made with atomic number (that is, electric charge) greater than 173, it would produce
an electric field strong enough to bring the energy of its innermost shell of electrons to the energy of the "Dirac sea.
