International PhD Scholarship in Heat Storage in Hot Aquifers , Denmark

The PhD scholarship is integrated in a project, where we will develop new technology to improve planning of energy storage in geothermal reservoirs through high-quality experiments and modelling. Geothermal reservoirs have high temperature, so energy may be stored in these geological layers with minimal heat loss. The technology will be based on a multidisciplinary approach combining small scale geochemistry/rock physics with large scale seismic inversion and history matching of production data. The focus will be on Danish geothermal reservoirs, because heat storage is likely to be the missing link in planning sustainable energy production in Denmark, where several sources of energy should interplay. Energy sources as waste incineration and wind are not controlled by immediate energy demands. By storing energy at low heat loss in hot aquifers, we obtain an effective interplay between different sources of energy. Thereby, the degree of coverage with sustainable energy can increase at an acceptable cost. It is the right time to do this, because geothermal plants are presently being installed in Denmark. Thus, the cost of establishing heat storage in geothermal reservoirs is relatively small. The imminent question with respect to establishing heat storage in geothermal reservoirs is how the reservoirs will react to the introduction of water with a higher temperature than the natural as compared to effects of injecting cold water: How will the reservoir rock react chemically and mechanically, how will the heat and fluid distribute in the reservoir, what is the energy loss related to this storage method, and how will a potential change in water chemistry influence the operation abilities of the geothermal plant? We will evaluate the technology in an international context by collaborating with researchers working with geothermal reservoirs in other European countries.

Qualification
At the date of appointment candidates must hold an MSc degree in geo-science or engineering (e.g. civil engineering, geology, geophysics, hydrology), preferably with a strong background in reservoir geology and/or rock physics. The successful candidate must be an efficient team worker, have good communication skills, and have a critical approach to formulation and testing of hypotheses. Practical lab experience and a wish to work in the lab is a prerequisite.

The scholarship is open to both Danish and international applicants.

Scholarship Application Deadline: 28 February 2011

PhD Position in Biophysical Chemistry,Lund University, Sweden

The position is linked to the research project “Molecular basis of heat and desiccation tolerance of bacterial cells and spores”, funded by Nestec Ltd, Lund University and the Swedish Research Council. The research work will be carried out at the Division of Biophysical Chemistry, which belongs to the Center for Molecular Protein Science in the Department of Chemistry. The Division is located at Lund University’s Center for Chemistry and Chemical Engineering (Kemicentrum). Kemicentrum is one of the largest research units for chemistry in Scandinavia with a staff of ca 400 and a yearly research budget of ca 350 million SEK. Research within the Division of Biophysical Chemistry ranges from water physics and nuclear spin relaxation theory to fundamental and applied problems in the life sciences, with a focus on protein interactions and dynamics.

Eligibility/Entry Requirements

The general eligibility requirement for doctoral studies is a university degree of at least 240 ECTS credits, including at least 60 credits at an advanced level.
We also welcome applications from highly motivated students who have not yet obtained their degree but will do so in the first half of 2011.

PhD Scholarship for Development of Functionally Graded Materials for Thermoelectric Devices, Denmark

The Fuel Cells and Solid State Chemistry Division at Risø DTU is seeking a Ph.D. student to develop graded thermoelectric materials with optimized properties over a broad temperature range for use in conversion of heat into electricity.
Thermoelectric power conversion is a promising technology for waste heat recovery in a broad variety of applications, e.g. transportation, building and industry. A thermoelectric device works by converting a certain temperature difference into an electric potential to generate power.

You will be part of a large project which aim to develop and demonstrate high-temperature efficient thermoelectric oxide modules integrated in a converter system.

This will take place at the international front line in collaboration between Risø DTU and four leading laboratories in Denmark, Japan and the US, while industry participation ensures strong links to both technology providers and end-users.

The project
A major challenge in thermoelectric materials development is to combine a number of materials belonging to different families of materials together in order to improve the conversion efficiency and to expand the working temperature range of the thermoelectric device. The project is focussed on the construction and optimization of p- and n-type segments over a broad temperature range by graded materials. This will be done in order to improve the so-called compatibility factor between the materials in each leg. The materials are chosen among the best of state-of-the-art materials and the novel developed thermoelectric oxides.

Qualifications
• Master’s degree in chemistry, physics, materials science or similar
• Knowledge in synthesis of inorganic materials preferably oxides
• Prior knowledge in the area of thermoelectricity is beneficial
• Experience with experimental methods for materials characterization
• Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamical group
• Good communication skills in English, both written and spoken

We offer
We offer an exciting and challenging job in an international environment.
Good possibilities for professional and personal growth.
A family friendly organisation with flexible working hours.
