    Ph.D candiate in Long term properties of polymers (IVT-122/09)


    Faculty of Engineering Science and Technology has responsibillity for the following disciplins: civil and environmental engineering, mechanical engineering, petroleum engineering, geology and mineral resources engineering and marine technology. The Faculty has 10 Departments (http://www.ntnu.no/ivt), about 750 employees, 3000 Master students, and about. 400 PhD candidates.
    Long term properties of polymers
    This project is part of a larger program within the composite and polymers group to investigate long term properties of composites and polymers. Applications are mainly related to energy generation and transport (conventional and renewable).
    Long term properties like fatigue and creep are influenced by the external environment. Chemicals diffuse into the material, cause a local reaction and the byproducts need to diffuse out. The local reaction on the atomic scale creates a change of the global engineering constants. This project shall model this behavior for polymers. The effects of fatigue, creep and external environment shall be combined to a unified approach. Test programs need to be designed and carried out to develop and verify the models.
    Testing and modeling will be challenging and go beyond standard procedures. You need to have excellent theoretical and experimental skills. Creativity and innovative thinking will be required to reach the goals. You will acquire a wide range of experimental skills and model development.

    The Norwegian University of Science and Technology has currently an open position as a PhD student in the area of prospective technology and option analysis for climate mitigation. The position is connected to the EU project “Development and application of a standardized methodology for the PROspective SUstaInability assessment of Technologies”. Prospective analysis would be achieved by modeling possible future production and consumption systems based on projected or potential improvements in technology and changes in consumption patterns and global wealth distribution. The position is also connected to the contributions of NTNU’s Industrial Ecology Programme to the Global Energy Assessment and the International Panel for Sustainable Resource Management. The Resource Panel work on the environmental impacts of products and materials focuses on determining the environmental impacts of products and materials from a life-cycle perspective, including development of assessments of the effects of trade and the assessment of improvement options. The researcher would directly support the Panel’s working group leader Edgar Hertwich in his work and would have the change to interact with experts at UNEP and other Panel members. The basis of both pieces of work is a multiregional input-output table of the world built by NTNU and project partners under the EXIOPOL project.

    The Industrial Ecology program (IndEcol) is an interdisciplinary research and teaching program managing its own International MSc program and PhD program. IndEcol has a high reputation within the field as evidenced by a high-profile international evaluation and the listing within top-publishing academic units in Norway. We are well integrated in the international research community through participation in ISIE, IIOA, SETAC, and other relevant research societies. Recent work on input-output analysis and emissions embodied in trade has received significant attention internationally, see http://carbonfootprintofnations.com

    The candidate should have strong analytical skills and quantitative modeling competence, good written and oral communication skills, and a willingness to engage in interdisciplinary and team work. Experience with mathematical modeling tools MatLab or GAMS is a requirement. Competence in life-cycle assessment and input-output analysis and a familiarity with industrial ecology, sustainability science or energy analysis is of advantage. The candidate should have a Masters degree in Industrial Ecology or a related discipline, or a Master degree in Science, Engineering or Economics and relevant job experience.

    Synthesis of novel functionalised or expanded oxacalixarenes and application in supramolecular chemistry

    50000403v1537
    Promoter: Wim Dehaen

    details
    Description: Calix[n]arenes are [1n]metacyclophanes that are relatively easy to prepare and functionalize, and, due to their high level of preorganization, they have been widely used as molecular platforms in supramolecular chemistry. Heteracalixarenes, in which the carbon linkages between the aromatic units are replaced by heteroatoms, are far less prevalent, although they inherently possess different properties that might expand the scope of classical calixarene chemistry.
    In previous work, we have explored the synthesis of oxacalix[m]arene[m]pyrimidines (m = 2–6) by nucleophilic aromatic substitution (SNAr) reactions of variously substituted m-dihydroxybenzenes and 4,6-dihalopyrimidines. Depending on the SNAr conditions, either a mixture of oxacalix[n]arenes (calix[4]- up to calix[12]arene), could be prepared or the oxacalix[4]arene could be synthesized selectively in a high yield (up to 80%).
    In this project, a (ring size) selective synthesis of oxacalix[m]arene[m]pyrimidines (m > 2) will be pursued by nucleophilic aromatic substitution. The resulting calixarenes will have two bridging atoms between the aromatic moieties.
    A second approach of structure modification is the intraannular substitution of the oxacalixarenes we obtained earlier by lithiation and electrophilic addition.
    The conformations of the novel oxacalix[n]arenes in the solid state will be investigated by X-ray diffraction studies.
    Binding studies of ssubstituted calixarenes systems in the presence of selected guests will be carried out by different spectroscopuc techniques.

    Metal-chelating biopolymers for removal of heavy metals from water (IRO scholarship)

    50000403v1644
    Promoter: Koen Binnemans

    details
    Description: Chitin is is a long, unbranched polysaccharide derivative of cellulose, where the C2 hydroxyl group has been replaced by an acetyled amino group NHCOCH3. It is the most widely occurring natural carbohydrate polymer next to cellulose. Chitin is prepared from shells of Crustacea (crabs, lobster, shrimps, …) at low cost by removing other components, such as calcium, and proteins, by treatment with acids and alkalines. Chitosan is obtained by deacetylation of chitin. The amine groups of chitosan are strongly reactive with metal ions. These amine groups are thus responsible for the uptake of metal cations by a chelation mechanism. However, the amine groups are easily protonated in acidic solutions. Hence, the protonation of these amine groups may cause electrostatic attraction of anionic compounds, including metal anions (resulting from metal chelation by chloride, anionic ligands, etc.). Chitosan can easily be modified by chemical or physical processes to prepare chitosan derivatives (obtained by grafting new functional groups) or to condition the polymer (by preparation of membranes or gel beads). The aim of this project is to chemically modify chitosan so that it has a very high capacity for uptake of heavy metals and especially for uptake of lead. The functionalization will involve transformation of the amine groups of chitosan into aminopolycarboxylate and related groups. The metal-binding capacity of these modified biopolymers will be determined as function of the pH of the aqueous solution, the temperature, and of the initial metal ion concentration. Competition experiments with mixtures of metals will be performed to measure the selectivity of the biopolymers for uptake of different metals (lead, copper, zinc, cadmium and arsenic). Special attention will be paid to the coordination chemistry of the metal ions bonded to the modified chitisan, i.e. it will be determined which type of complexes are responsible for the metal binding. It will investigated how the coordinated metals can be released from the modified chitosan so that the biopolymer can be recycled after use. This project is an interdisciplinary project involving synthetic organic chemistry, coordination chemistry and analytical chemistry. The student will make use of different analytical techniques including NMR spectroscopy, Raman spectroscopy, optical absorption spectroscopy, EXAFS, atomic absorption spectroscopy (AAS) and total reflection X-ray fluorescence (TXRF).

    Remarks: Relevance for development co-operation:
    Polution of drinking water by the heavy metals mercury, lead, cadmium, zinc, copper, zinc, manganese, chromium and arsenic are a serious problem in developing countries. These metals cause even in trace amounts serious health problems and are lethal in larger concentrations. Although severe contamination of water is caused by the development of the mining, metallurgical and chemical industries, in many cases the poisoning of drinking water is not caused by these industrial activities but by geological causes. When a deep well is drilled through metal-containing rocks or sediments, these metal will be leached from the rocks into the water. Filtering the water through sand beds or cooking the water will not remove these heavy metal impurities. Metal-chelating polymers are able to eliminate traces of heavy metals from water and only small amounts of them are necessary to perform this task. The advantage of using chelating biopolymers is that they can be produced from organic waste that is available in many countries, especially those lying along the seas or oceans. It is possible to regenerate these biopolymers after use so that they can be recycled over and over again. This considerably reduces the overall costs per liter of purified water, so that such water purification methods are affordable by people in developing countries.

    Non-photochemical routes to diazahelicenes

    50000403v1538
    Promoter: Wim Dehaen

    details
    Description: Helicenes containing nitrogen heteroatoms will be prepared by constructing bicyclic and tricyclic building blocks, connecting them and carrying out a cyclisation or cycloaddition by non- photochemical ways.
    Thus, racemic helicene compounds are obtained that can be resolved by using the formation of diastereoisomers, chiral (HPLC) chromatography, or crystallisation techniques. Another alternative is the enantioselective helicene formation.
    The helicenes will be substituted with functions that will allow to study the NLO properties together with the research team of Prof. Dr. Koen Clays (GOA-project). Other applications are enantioselective catalysis.
    There is a material relevance, but basically this is a study of synthetic methodology.

    the way to drug development: microwave-assisted generation of new privileged structures, possessing a medium-sized ring (IRO scholarship)

    50000403v1629
    Promoter: Erik Van der Eycken

    details
    Description: The present PhD-research proposal fits in one of the main research topics of the Laboratory for Organic & Microwave-Assisted Chemistry (LOMAC) dealing with the investigation of the synthesis of medium-sized ring containing natural products and analogues, which is known to be rather difficult. Therefore the application of microwave irradiation – the core business of LOMAC1 - plays a key role in these investigations. The expected rigidity of the medium-sized ring in the proposed compounds, makes these systems excellent candidates to be elaborated as privileged structures en route to the development of novel drugs. This nicely fits into another main research topic of LOMAC: the development of novel small and rigid molecules to be investigated as privileged structures for the generation of peptidomimetics in the light of drug design.
    Among natural compounds and important pharmaceuticals the 3-benzazepine framework is abundantly present. Considerable efforts have been made towards the synthesis of alkaloids as aphanorphine2, lennoxamine3 and cephalotaxine4 (Figure) because of their challenging chemical structures and interesting biological activity. The renal vasodilator Fenoldopam relates to the class of 1-substituted tetrahydro-3-benzazepines and is a peripheral dopamine D1 receptor agonist.5 The tetracyclic MK-801 (Dizocilpine) represents a non-competitive NMDA receptor antagonist and has been extensively studied for treatment of neurodegenerative diseases such as Huntington's, Alzheimer's, and amyotrophic lateral sclerosis.6 Variously substituted at position 1, the 3-benzazepine structure has also been studied for the synthesis of potent NMDA receptor antagonists.7
    Most often the construction of the medium-sized ring of the 3-benzazepine scaffold is achieved via intramolecular Friedel-Crafts alkylation.2b-d,6b,8 However, this method demands an excess of Lewis acid and lacks flexibility for variation of substituents. Alternatively, ring closure is accomplished upon formation of the C-N bond via intramolecular reductive amination.7a Intramolecular radical cyclization was successfully applied for the synthesis of the 7-membered ring in aphanorphine.2a,e Particularly useful for the syntheses of natural compounds and analogues is the corresponding 3-benzazepinone structure, as alkylation allows further introduction of substituents, for example, giving rise to bridged structures.2c,d,9 Transition metal-catalyzed reactions were also used for generating the 3-benzazepine scaffold. Thus, the Heck reaction of olefins proved to be high yielding and reliable.4a,b,7b,10 Though this approach regioselectively leads to 7-membered rings, a problem with the geometry and location of the resulting double bond still remains, due to the unselective elimination of palladium-hydrogen species at the final step of the Heck reaction.2e,4a,10a On the contrary, as a result of the mechanism, our approach via intramolecular Heck reductive cyclization on a triple bond assures full control over the ring size and the geometry of the double bond.11 A regioselective synthesis of 4-substituted 3-benzazepinones via intramolecular hydroamidation of the triple bond incorporated in the noncyclic precursor has also recently been reported.12a,b
    However, to the best of our knowledge the 3-benzazepine structure has not been regarded as a potential privileged scaffold and no studies are available for generating diversity oriented small combinatorial libraries of this and related medium-sized ring scaffolds. Moreover, the fact that medium-sized rings are generally considered to be the most difficult ring sizes to synthesize (due to their associated torsional, transannular and large-angle strain, which makes these rings relatively conformationally rigid), adds additional challenges to the proposal.13
    The term “privileged structure” was originally coined by B. E. Evans at Merck, who recognized that benzodiazepine structures do not only bind to benzodiazepine receptors of the CNS, but also to cholecystokinin receptors, even though the natural ligands bear little resemblance to this class of compounds.14 According to the definition of Evans, privileged structures are a compound class that can bind to various protein-receptor surfaces with high affinity. These structures appear to contain common structural features. Since the term privileged structure was introduced, a variety of organic scaffolds including biphenyl, have been described as privileged structures.15 The expected rigidity of the medium-sized ring in the proposed compounds, makes these systems excellent candidates to be elaborated as privileged structures. The specificity for the different receptors depend on the substituents introduced on the scaffold. Therefore combinatorial libraries have to be constructed and screened. Libraries based on privileged structures as scaffolds, displaying a diversity of appended pharmacophoric groups, have much greater probability for generating hits in a screening against various drug targets.
    A diversity oriented synthesis of small combinatorial libraries of 3-benzazepines and related medium-sized ring analogues will be investigated in solution phase and on solid support. We will rely on a previously developed strategy of our Laboratory for Organic & Microwave-Assisted Chemistry (LOMAC), for the synthesis of 1-substituted 3-benzazepinones11, based on a microwave-assisted intramolecular Heck reductive cyclization reaction on a triple bond (Scheme). The applied strategy assures the exclusive generation of compounds possessing the Z-conformation of the exocyclic double bond as well as the exclusive formation of the 7-membered ring. The presented PhD-research proposal aims at the further evaluation of this new microwave-assisted protocol for the diversity oriented synthesis of 3-benzazepines and related medium-sized ring analogues.
    - The scope and limitations of the procedure will be investigated by variation of the tether.
    - Alternative “domino protocols” such as Heck reaction followed by Suzuki/Miyaura, Heck or Sonogashira reaction will be investigated.
    - New precursors for our Heck intramolecular reductive cyclization reaction on a triple bond will be generated via an enantioselective A3-coupling procedure or via a post-Ugi 4-component reaction (U-4CR)/Heck reductive cyclization, ensuring diversity.
    - The á,â-unsaturated carbonyl of the generated benzazepinones will be evaluated for the further decoration of the scaffold via radical cyclization. This will be exemplified by the synthesis of a natural product analogue, the methylated (+/-)-O-methyl-thalisopavine.
    - The post-U-4CR/Heck reductive cyclization will be translated to solid phase organic synthesis (SPOS).
    The application of microwave irradiation will play a central role in this PhD-project, although without having the intention to determine the existence of special, non-thermal microwave effects. Microwave irradiation will be used purely as a technique.
    This research will result in the generation of a number of new compounds with hitherto unknown skeletons which will be evaluated as privileged structures by in-house (K. U. Leuven, i.a. at the Rega-Institute), broad screening for biological activity. Possible lead compounds will be further investigated and optimized on the way of drug development. This will be done in close collaboration with the screening partners at K.U.Leuven.

    Description: Hanoi, the Capital City of Vietnam has the name of City of Lakes. The old Hanoi has a total area of about 100 km2. Within this area there is about 1000 ha of water surface with more than 100 lakes. The Hanoi lakes system has an important place in the life of Hanoi citizens. Its functions are multi-purpose: (i) recreation-entertainment places, (ii) microclimate creators, (iii) inundation buffers and (iv) partial wastewater sewerage, to name but a few.
    In 2010 Hanoi is going to celebrate its 1000-year of foundation, and the Hanoi Municipality has launched a large program for lake cleaning and conservation to contribute to making-up the City to meet its 1000-year anniversary. In the past and at present, in Hanoi, only the conventional approach for lake cleaning is applied: pumping out all the water, letting the bottom dry, dredging up the mud by excavators and transporting the mud. It is evident that this is a time, labor and energy consuming practice which is far from being sustainable. Hence, there is an urgent need for alternative technological solutions for lake cleaning without (or with minimum) mud dredging/transport. To enhance the sustainability of the alternative technologies, they should prevent instead of remedy the generation of the vast amounts of the to-be-dredged muddy material.
    Apart from suspended solids that enter the lakes through the incoming water flows, the abovementioned mud primarily consists of dead algal biomass. These algae are present in abundant amounts due to severe eutrophication of the lakes’ water. In addition to the need for dredging, the (dead) algal biomass causes odor and high water turbidity problems and can release toxins in the water.
    To save the lakes, the ideal approach is to limit the nutrient concentrations in the incoming water flows, but this is not always possible, especially not in low-income, high population density developing countries like Vietnam. Therefore, low-cost, environmental-friendly cleaning technologies that prevent and/or combat the algal bloom without extensive use of chemicals, need to be developed.

    This PhD research proposal is aimed at developing a suitable mathematical model to predict the effectiveness of specific treatment measures to improve the lake water quality in Hanoi, thereby enabling the prediction of the lakes’ long-term water quality. The envisaged treatment measures will primarily be aimed at improving the self-cleaning capacity of the lakes by exploiting the interaction between floating aquatic plants, microbial activity and algae, where the latter might have to be suppressed by additional techniques such as ultrasound based technologies

    To gain insight in the interactions between (i) the aquatic plants and their associated rizoshere microbial activity, (ii) the suspended micro-organisms and (iii) the algae and to assess their mutual impact on the lake water quality, an extensive experimental plan will be conducted. The inferred insights will then be translated to a mathematical model. The model will enable the prediction of the cleaning effectiveness of the techniques, thereby enabling to forecast the long-term performance of the lakes.
