An investigation of the agronomic value of fine grinding and granulating reactive phosphate rocks : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science in soil science at Massey University, New Zealand [PDF]

open access: yes, 1990
The future trends in the use of reactive phosphate rocks in New Zealand may be dependent on improving the handling characteristics of these fine sand- and powder-like materials. Granulation of these materials has been suggested as one option.

Iridium complex, a phosphorescent light-emitting diode material, serves as a novel chemical probe for imaging hypoxic tumor tissues [PDF]

open access: yes, 2007
Iridium complex, a promising organic light-emitting diode for next generation television displays, emits phosphorescence. Phosphorescence is quenched by oxygen. We used this oxygen-quenching feature for imaging tumor hypoxia.
