Hadfield

In fact, the most prominent woman in analytical chemistry, Isabel Hodgson Hadfield,14 did not join the Society until 1944. Bom on 29 January 1893, her father a schoolmaster, Hadfield graduated from East London College (later Queen Mary College) in 1914. The following year, she obtained a Diploma of Education and became a Chemistry Mistress with the Birmingham Education Council. 

During the First World War, the need for scientists overrode the traditions of society and women were pressed into scientific 

Much of the analysis involved small samples and, as a result, Hadfield became a pioneer in the development of micro-analytical measurements.15 In the 1930s, she was a founder member of the Microchemical Club. She retired with the rank of Principal Scientific Officer in 1953 in order to look after her elderly father. After his death, she went to live with a friend in Hampshire where she stayed until her own death in February 1965.

Figure 7.8. Material hardness of Hadfield steel subject to shock compression of various peak pressures and pulse durations.

Champion and Rohde [42] investigate the effects of shock-wave amplitude and duration on the Rockwell C hardness [41] and microstructure of Hadfield steel over the pressure range of 0.4-48 GPa (pulse duration of 0.065 s, 0.230 ls, and 2.2 ps). The results are shown in Fig. 7.8. In addition to the very pronounced effeet of pulse duration on hardness shown in Fig. 7.8, postshoek electron microscope observations indicate that it is the final dislocation density and not the specific microstructure that is important in determining the hardness.

Much data point to an Intimate connection between H2 and the N2 binding site in nitrogenase. Simpson and Burrls(58) confirmed the important finding of Hadfield and Bulenf59) by showing that one H2 is evolved for each N2 "fixed" even at 50 ATM N2, which is well above the pressure of N2 at which saturation occurs. H2 evolution is therefore a mandatory part of the N2 fixation process( - ) whose stoichiometry must be written as ...
