Background
John is a Physical and Colloid
Chemist with complementary training in metallurgy, whose research interests
embrace various aspects of interfacial science and engineering. John is the
founding Director of The Wark and a Professor of Physical Chemistry and
Minerals Processing. He was the driving force behind the establishment of
the Ian Wark Research Institute in 1994, and over the past three decades, he
has actively supervised more than eighty PhD research students. These
students have gone on to establish successful careers in universities,
industry and other research institutions all around the world. He is the
author of over 350 refereed journal articles and textbook chapters, plus
numerous conference papers and industry reports, acts as referee for major
international journals and is presently a Council Member of the
International Association of Colloid and Interface Scientists (IACIS). Since
1984, John has been awarded over $200M in competitive grant funding from the
Australian Research Council, the Department of Education, Science and
Training and national and international private industry.
Throughout his career he has held invited Professorships in Cape Town,
Lulea, Bristol, Utah and Florida and holds an Honorary Doctorate from the
Abo Akademi in Finland, as well as Honorary Professorships in Materials
Science and Engineering at Tianjin University in China and the Graduate
School of Engineering at the University of Tokyo.
John was the principal researcher who led the initiative to establish the
Australian Mineral Science Research Institute (AMSRI) which commenced on 1
January 2006. AMSRI is a virtual institute in particle science and
engineering, with its headquarters at The Wark and involves collaborative
research at the Universities of Queensland, Melbourne and Newcastle. Major
international companies are involved, through AMIRA International, along
with overseas collaborators, in this long term strategic research.
Outside science, he has a strong interest in literature, world history,
travelling and sport, especially skiing.

"John Ralston is an internationally recognised expert in colloid and surface
chemistry and their application in metallurgical engineering and technology.
His research is internationally recognised in the physical chemistry of
mineral flotation processes, the surface chemistry of metal sulphides, and
the static and dynamic wetting behaviour of simple and structured solid
surfaces. In 1994 he established the Ian Wark Research Institute, which is
now recognised worldwide for its fundamental research in interfaces,
initially with a strong mineral focus. The Institute is an Australian
national treasure that has now broadened its activities across many
disciplines. Ralston excels in the application of his science to real world
problems".
Scientific Focus
John is a physical chemist, specialising in colloid and surface chemistry,
with complementary training in metallurgical engineering and technology, who
has made major contributions to the:
- interactions of bubbles and particles, emphasising the fundamental physical chemistry of the elementary steps of collision, attachment (eg three phase contact line kinetics for a S/L/V system) and detachment. This work has included a very comprehensive collision model and the extension of these elementary process descriptions to interactions in mixed, turbulent systems, including ores, in landmark papers.
- solid-liquid interfacial chemistry of metal sulphides, oxides and silicates, including the action of organic and inorganic reagents. Of particular significance is his work on metal sulphide surfaces, including observations of the earliest stages of heterogeneous oxidation and the first quantitative detection of elemental sulphur.
- static and dynamic aspects of surface wetting, including surfaces which respond to external light, electric potential (electrowetting) and thermal influences.
- scanning probe microscopy in imaging and colloid probe modes, of solid and fluid surfaces. This has involved the direct measurement of bubble-particle interaction forces and the first determination of the line tension (SLV) of surface 'nanobubbles'. The first direct link between polymer adsorption at the solid-liquid interface and the structure of the solid surface has been demonstrated.
- use of infrared spectroscopy to identify the presence of dissolved gas at the hydrophobic solid-water interface, its link to surface heterogeneity and an interpretation of the hydrophobic force based on the alteration only of DLVO interactions.
- the application of this research in industry (minerals, pharmaceutical, specialty manufacturing and chemical industry).
