A team of chemists has developed a method to yield highly detailed, 3D images of the insides of batteries. The technique, based on magnetic resonance imaging (MRI), offers an enhanced approach to monitor the condition of these power sources in real time.
The ASM International Board of Trustees announces the appointment of William T. (Bill) Mahoney as Managing Director effective immediately.
Bodycote, Macclesfield, England, announces that it has acquired Nitrex Metal Technologies, which specializes in precision gas nitriding and ferritic nitrocarburizing in both batch and continuous processes.
Because of the use of nitrogen as an alloying element in these stainless steels, chromium nitrides (CrN) may be present on α/α grain boundaries, on γ/α boundaries, and within the α grains. If formed in large quantities and under conditions in which the chromium-depleted areas do not have time to repair themselves during annealing, the presence of CrN may adversely affect corrosion resistance.
Uranium mining methods produce a liquid with uranium dissolved in it. This is filtered and the uranium is then separated by ion exchange, precipitated from the solution, filtered, and dried to produce a bright yellow uranium oxide concentrate known as ‘yellowcake,’ which contains 0.7% U235.
