A synchrotron facility opens up areas of problem
solving that have never been accessible before. It can be used to
extend the capability of existing investigation techniques but, more
importantly, totally new methods of study are possible.
Cetec is using the high spectral intensity emitted by
the synchrotron to investigate industrial problems such as:
-
Poor Adhesion in metal and polymer coated plastics;
-
Early failure of metals by fine pitting corrosion
and
-
Duty failure of carbon fibre-epoxy composites.
To facilitate international access and expertise,
Cetec has established a base in the United Kingdom. We would
welcome further enquires on likely applications from Australia or
overseas.
Listed below are some published applications by
industry category
Food and Biology
The biological functions of an organism are governed
by large and complex molecules, like sugars, starches, vitamins,
proteins, enzymes or viruses. Synchrotron light is increasingly used
to develop new products and to investigate processes.
Chemistry
Chemistry relates to atomic and molecular
transformations occurring when different substances are brought in
contact. Now, reactions can be studied dynamically by synchrotron
techniques in order to follow a chemical reaction as it happens to
yield new insight in the kinetics of chemical reactions, directly from
the reaction zone and often under extreme conditions.
The synchrotron allows for studies of extremely
small samples or very low levels of contaminants even for
poorly interacting compounds in a time-resolved manner for
understanding of, for example, polymerisation processes, the hydration
process of Portland cements, environmental depositions, air pollutant
behaviour and agricultural soil uptakes.
Using X-ray microscopy allows for the possibility
to create highly contrasted transmission-mode pictures of "thick"
samples, such as entire biological cells in a water environment.
This is of great benefit in fields such as colloid research or earth
sciences, where the sample preparation necessary for other methods of
high-resolution microscopy itself would inflict significant
alterations in the structures to be investigated.
Materials
The properties of materials require knowledge of their
microscopic structure. Synchrotron radiation facilities allows new
lower limits to determine the atomic structure of natural and
artificial polymers, mechanical tension leading to the
formation of microfractures, the morphology of material ageing
and fatigue.
Element-selective studies of magnetic structures
can be carried out with an X-ray microscope by exploiting
circular-magnetic X-ray dichroism - magnetic absorption. These
studies help explain the micro-magnetism in quite different magnetic
materials. Magnetic nanostructures are becoming increasingly
important for data storage techniques.
Basic and applied research are combined to develop the
materials and technologies of the future and for resolution of
forensic problems.
The outer of bulk materials, i.e. the surface, is
decisive for the appearance of an object. Surfaces and interfaces play
an equally important role in science. The surface of a solid differs
considerably from the interior in terms of physics. Surface properties
can be substantially different from the bulk material properties and
play an important part in cohesion, adhesion, catalysis, or corrosion,
surfaces.
Veterinary and Human Medicine
Spectacular results have been obtained in medical
imaging. The small spot size of the X-ray beam allows Computed
Micro-Tomography (CMT) to be carried out, yielding a 3-dimensional
reconstruction of human tissues with spatial resolution in the
micron range (1millionth of a metre). The technique can also be
used to image the diminution of bone structure with ageing,
while an in-line holography set up allowed the monitoring of a
coronary artery with plaque and thrombosis.
In vitro studies can also be performed as can X-ray
based clinical research in the fields of medical imaging and radiation
therapy.
Physics
As the experimental analysis of the intrinsic
properties of matter is the key to the advancement of technology,
the materials of the future are the subject of fundamental research
today.
For example, simulating the conditions of ore
formation under high pressures and at high temperatures, is of
particular interest to geophysicists and geochemists.
As a second example, the difference of X-ray
diffraction patterns of block co-polymers taken at rest and under flow
has yielded new insights into the rheology of polymers, explaining
the viscosity change of a particle suspension as function of flow
conditions.
Cetec is an advanced scientific consultancy for industrial risk
assessment and management. The core of the services revolve around
high quality, relevant data acquisition by appropriate techniques
within or outside our laboratories. Thirty years of experience has
taught us that:
-
no one technique can solve all technological
problems;
-
the most advance techniques will mostly yield the
greatest insight;
-
the consultant must be intimately familiar and
involved with the techniques used and with the specialist operators;
-
the consultant, in most cases, must attend the site
of the problem for it to be solved;
-
The solution must be relevant and interpretable to
the client and
-
The solution must be timely and financially
effective.
