A new small-scale interfacial voltaic cell is shown to be satisfactory for potassium permanganate Oxidation-Reduction potentiometric titration in milligram and microgram amounts of the samples.
首次提出了一种新的氧化还原电位滴定的终点指示器界面伏打电化学池。
While concentrations varied daily, typical concentrations of lead particles ranged from 0.6 to 1 microgram per cubic meter of air, Bell and her thesis adviser Catherine Cahill found.
About 25% of the food items, including spices such as cardamom, fenugreek and chili powder, contained more than 1 microgram of lead per gram of product.

A single 15 microgram dose of swine flu vaccine is enough for kids 10 and older, while children under 10 will need two doses, 21 days apart.
Whether this has a potential for carry over into food at low concentrations (usually in the range of microgram per kilogram) and could further impact human health may need further evaluation.
Combined with the design of a math coprocessor, the paper dis-cusses how to determine microinstruction format and write microgram code. Multiplication code is presented as an example.
