masurium การใช้

• Their choice of the term masurium was also considered unacceptably nationalistic and may have contributed to a poor reputation amongst scientists of the day.
• Still, in 1933, a series of articles on the discovery of elements quoted the name " masurium " for element 43.
• Her suggestion was not taken seriously at the time because her team had not carried out any experiments with uranium, and its claim to have discovered masurium ( technetium ) was disputed.
• In 1925, they published a paper ( Zwei neue Elemente der Mangangruppe, Chemischer Teil ) claiming to have done so, and called the new elements Rhenium ( 75 ) and Masurium ( 43 ).
• German chemists Walter Noddack, Otto Berg, and Ida Tacke reported the discovery of element 75 and element 43 in 1925, and named element 43 " masurium " ( after Masuria in eastern Prussia, now in Poland, the region where Walter Noddack's family originated ).
• :: : : " The chemist Ida Noddack criticised Fermi's work and suggest that some of Fermi's experiments could have produced lighter elements, but was not taken seriously at the time because her team had not carried out any experiments with uranium, and their claim to have discovered masurium was disputed.
• On 22 December 1938, Hahn sent a manuscript to " Naturwissenschaften " reporting their radiochemical results, which were published on 6 January 1939 . On 27 December, Hahn telephoned the editor of " Naturwissenschaften " and requested to add a paragraph to the article, speculating that some platinum group elements previously observed in irradiated uranium, which were originally interpreted as transuranium elements, could in fact be technetium ( then called " masurium " ) and lower platinum-group metals ( atomic numbers 43 through 46 ).
