This process creates a positive charge
. On a battery, the positively charged end is the one marked with the plus sign.
In this experiment, water exposed to a positive charge
froze at higher temperatures than water exposed to a negative charge.
At this pH there are equal amounts of negative and positive charge
, irrespective of the origin of charge, and hence CE[C.sup.T] = AEC at PZNC.
Above pH 7, chitosan lost its positive charge
. Large aggregates of emulsion droplets visible under the microscope formed.
We assume that cationic latex will work as a retention aid because of its positive charge
, attracting it to the anionic fibers and the anionic clay.
Along with being a high-strength glass, experiments indicate that the material could be used to store energy -- during processing, the glass-forming melt acquires a positive charge
when electrons are extracted from it.
To remove surface graphite from castings, the chemical reduction cycle is followed by a chemical oxidation cycle that requires a positive charge
, creating metallurgical voids to improve bonding during brazing, tinning, babbiting and soldering.
In the case of metals, the anionic biosurfactant carries a negative charge, so when the molecule encounters a cationic metal such as lead that carries a positive charge
, an ionic bond is formed that is stronger than the metal's bond with the soil.
Barrels receive a positive charge
while the cathode has a negative charge.
Plant roots grow in every direction in zero-gravity space, but Mukai's team has found that the roots, when exposed to a 30-volt electrical charge, extended toward the positive charge
, an outcome that may make future vegetable growing in space easier, Ishikawa said Sunday.
(The Polish chemist Kasimir Fajans [1887-1975] made these same suggestions independently at about the same time.) When an atom gives off an alpha particle, the alpha particle has a positive charge
of 2 and a mass of 4.
Researchers on the team found that a positive charge
is the primary determinant of whether a molecule gets in to E.
