Mass loss of platinum-rhodium thermocouple wires at 1324°C

Erratum: Thermal Expansion of Platinum and Platinum-Rhodium Alloys

Erratum: Equation (22) contains an error. It should read 100 ɛ(t, 0 °C) = 8.79 × 10 −4 t + 0.805 × 10 −7 t 2. (22) Also, the data presented in Table 12 under the column Day and Sosman Eq. (22) should be evaluated by using the corrected Eq. (22) above.

Vapor Pressures of Platinum , Iridium , and Rhodium

Systematic measurements of the vapor pressure of iridium and rhodium over a wide temperatme range have not been published previously. A summary of previous estimates or observations of their normal boiling points and values of their heats of sublimation, f:..H ~ (298), is given in table l. The vapor pressure of platinum was calculated by Langmuir and .Mackay from measurements of the rate of sub...

Platinum and Rhodium Silicide–Germanide Optoelectronics

Since the introduction of SiO2/Si devices in the 1960s, the only basic change in the design of a MOSFET has been in the gate length. The channel thickness has fundamentally remained unchanged, as the inversion layer in a silicon MOSFET is still about 10 nm thick. Bipolar transistor base widths have been of sub-micron dimensions all this time. It is time for a new property to be exploited in con...

A rhodium/silicon co-electrocatalyst design concept to surpass platinum hydrogen evolution activity at high overpotentials

Currently, platinum-based electrocatalysts show the best performance for hydrogen evolution. All hydrogen evolution reaction catalysts should however obey Sabatier's principle, that is, the adsorption energy of hydrogen to the catalyst surface should be neither too high nor too low to balance between hydrogen adsorption and desorption. To overcome the limitation of this principle, here we choos...
