This reference mass is used to calibrate national standards made of platinum-iridium
Experts are willing to make the changes so that it is no longer based on the mass of a solid cylinder of platinum-iridium
alloy that sits beneath three layers of protective glass sealed in a locked vault in Sevres, France.
Where in France is the platinum-iridium
cylinder which represents the standard kilogram stored in France?
Electrochemical oxidation of hydrogen peroxide on platinum and platinum-iridium
electrodes in physiological buffer and its applicability to hydrogen peroxide-based biosensors.
Among global standards for length, mass, time, and other fundamental quantities, only the kilogram remains a physical object--a carefully machined cylinder of platinum-iridium
alloy at the International Bureau of Weights and Measures at Sevres, France.
Superior gold-tip catheter outperforms platinum-iridium
tips - maximum voltage-guided technique is optimal versus conventional ablation
Since a small molecule requires a comparably small sensor, the team used a platinum-iridium
electrode with a diameter of only 15 nanometers to measure the current.
Since 1889, a single platinum-iridium
bar has lain sealed in an airtight bell jar in the International Bureau of Weights and Measures in Sevres, France.
The Aescula(TM) 1055K left-heart lead is a stylet-driven silicone insulated lead with a titanium nitride (TiN) coated platinum-iridium
These improved mass measurements may also contribute to an ongoing effort to produce an atomic standard for mass, replacing the platinum-iridium
cylinder currently representing a kilogram (SN: 4/24/93, p.
It uses a titanium nitride (TiN) coated platinum-iridium
electrode and steroid-eluting collar designed for optimum threshold performance.
Careful recalibration against the so-called international prototype of the kilogram -- a lump of platinum-iridium
alloy that sits in a vault at the International Bureau of Weights and Measures in Sevres, France -- showed the U.
