PhD Scholarship

New delivery agents for nanosized zero-valent iron: Fe/C nanocomposites for in situ reductive remediation of pollutants

Financed by the Environmental Protection Agency, at the School of Chemistry of Trinity College Dublin under the supervision of Dr. Paula Colavita.

We invite applications for a 3 year PhD scholarship available for a candidate interested in developing new composite materials for the smart delivery of nanoparticles through porous matrices for the in situ remediation of pollutants.

The project requires a multidisciplinary approach to the problem of targeted delivery of nanomaterials in soils. The applicant will develop new methods in materials synthesis, surface functionalisation and characterisation in order to prepare nanocomposites with tailored transport properties. Kinetic and transport studies will be carried out in order to understand particle-particle and particle-grain interactions. The project has a dual focus on both basic and applied science. A fundamental understanding of the interfacial physical chemistry of the proposed materials will be leveraged in order to develop successful approaches to the implementation of environmental nanotechnologies.

This postgraduate experience will be at the intersection of materials, analytical and physical chemistry. Applicants with different backgrounds in the general area of chemistry, chemical/environmental engineering or a related subject will be considered. Applicants are expected to demonstrate a record of academic excellence. Independent work, strong self-motivation, and good communication skills are important assets of the successful candidate. Due to funding constraints, only EU candidates can be considered. The position will remain open until filled with an anticipated registration in autumn 2008.

Informal enquiries are welcome. Interested candidates should send CV and cover letter, preferably via email.

Trinity College Dublin

PhD Studentship

One PhD studentship under the supervision of Dr. Paula Colavita is available at the School of Chemistry, Trinity College Dublin.

Two possible projects are currently available:

Project 1: Model surfaces for the investigation of photochemical heterogeneous reactions on carbonaceous aerosols. While the use of model surfaces to understand complex heterogeneous chemistry of environmental relevance has been successfully applied to the study of aerosol chemistry, suitable surfaces for simulating carbonaceous aerosols have remained elusive. Despite the importance of combustion soot for establishing the extent to which our environment is perturbed by human activities, few studies on well defined surfaces have been utilised to investigate carbonaceous aerosol chemistry. The applicant will develop model carbon materials whose composition, electronic structure and surface chemistry can be tailored to mimic different types of soot and organics/soot micro/nanoparticles. Photo-induced heterogeneous reactions of environmental relevance will be investigated on these substrates in order to identify structure/reactivity relationships.

Project 2: Biomimetic surfaces for the investigation of carbohydrate biorecognition processes. The investigation of surface binding and adsorption of biomolecules can be used to understand recognition processes of importance in biology, from cell adhesion to immunological response. The role of carbohydrates in biorecognition represents one of the current frontier research areas. Carbohydrate surface arrays are among the most promising research tools for investigating biorecognition. However, limited attention has been devoted to developing surface chemistries that allow to display controlled molecular composition, structure, conformation and topography for this application. The candidate will develop functional surfaces that bear carbohydrate moieties with controlled composition and structure, in order to quantitatively investigate specific and unspecific interactions between carbohydrates and biomolecules.

Applicants involved in these projects will receive strong training in the areas of physical and materials chemistry, however, the resulting work is expected to have multidisciplinary impact. Depending on candidate interests and abilities there is room to accommodate specific interests within the outlined objectives. Applicants are expected to demonstrate a record of academic excellence. Independent work, strong self-motivation, and good communication skills are important assets of the successful candidate. Due to funding constraints, only EU candidates can be considered. The position will remain open until filled with an anticipated registration in autumn 2008.

Informal enquiries are welcome and encouraged. To know more about these openings please send CV and statement of interests, preferably via email.
