It forms yellow, monoclinic crystals; made from ammonium hydroxide and ammonium dichromate; used in photography as a sensitizer for gelatin coatings.
42.
Because electrons encounter many grain boundaries during the transit and experience a random path, the probability of their recombination with oxidized sensitizer is increased.
43.
The sensitizer used is very slow, so printing must be by contact with a large format negative, using an ultraviolet lamp or sunlight.
44.
Hence, if an excited molecule transfers its energy to a sensitizer thus exciting it, longer and easier to quantify light emission is often observed.
45.
Therefore, this transfer must be a non-radiative one with a mercury atom as the donor or sensitizer and the thallium atom as the acceptor.
46.
Because if their relative ease of use, along with size-tunable excitation attributes, quantum dots have commonly been applied as sensitizers in optoelectronic devices.
47.
The new drug is a cousin to Rezulin, an earlier formula of insulin sensitizer that was pulled from the market after it was linked to liver damage.
48.
The excited sensitizer then reacts with either a substrate or ground state molecular oxygen, starting a cascade of energy transfers that ultimately result in an oxygenated molecule.
49.
Dissolved organic matter ( DOM ) in the surface waters act as the photo-sensitizers and produce reactive photooxidants as hydroxyl radicals, peroxyl radicals and singlet oxygen.
50.
To stabilize the metastable glass formed by the leuco dye, developer and sensitizer, a fourth type of material called a stabilizer is often added to thermal papers.
