Studies of oxime complexes
Published 1981“…The complexes Fe(Ppo)2.H2O, Fe(Ppo)2 .2py and Fe(po)2.H2O were found to be high spin. This property contrasts the behaviour of iron(II) complexes derived from 2-nitrosophenols, which are low spin, and is rationalised in terms of conjugation effects and the bonding character of the pyrazol-4, 5-dione monooxime ligand. …”

The potential for suppressing rail defect growth through tailoring rail thermo-mechanical properties
Published 2016“…Thermal damage of rails can occur through brake lock-up, or traction control system failure to prevent wheel spin. In most cases the damage produced is shallow and takes the form of a “white etching layer”, usually thought to have a martensitic structure, formed as the steel is heated above its eutectoid tem-perature and then rapidly cooled as the wheel moves away. …”
