I joined John’s group at the Research School of Chemistry (RSC), Australian National University, Canberra in the mid 1990’s. Here I was quickly introduced to x-ray scattering from interfaces followed by the application of neutron scattering to the same systems. Australia’s first X-ray Reflectometer capable of studying free liquid surfaces had been built using the Elliott GX-13 fine focus...
Hydrated uranium(VI) oxyhydroxides will be an important mineral group within the alteration phases formed during the corrosion of spent nuclear fuel, in the case where groundwater has entered a breach in the fuel cladding. By controlling the addition of base to an aqueous uranyl solution, we have shown that crystalline films of layer lattice uranium oxyhydroxides can be grown on silicon [1] or...
Despite recent attention to nanoplastics, there is still much to learn about their surface coatings that give them their “bioidentity”, which is critical to their behaviour in biological contexts. These coatings, corona, form on the particle as a complex mixtures of proteins and other surface-active chemicals – some strongly bound, and others weakly attached and exceptionally hard to study–...
Although Dr. John White’s research focused mainly on using Small Angle Neutron Scattering, we are honoured to dedicate this science revealed on Cold Neutron Triple Axis Spectrometer SIKA at ANSTO to Dr. John White for his support and guidance during the construction of SIKA and the establishment of Taiwan Neutron Scattering Society (TWNSS).
In the search for green energy, thermoelectric...
It has been known for almost one hundred years that a lower surface tension can be achieved at the air–water interface by spreading protein from a concentrated solution than by adsorption from an equivalent total bulk concentration. Nevertheless, the factors that control this nonequilibrium process have not been fully understood. In the present work, we apply ellipsometry, neutron...
