Ag NWs for Organic Photovoltaic Cells: Semitransparent and Stretchable Devices
No full textThe current developments on organic photovoltaic (OPV) solar cells are inspired by the idea that they can be processed from solution. One of the challenges in developing fully solution-processed OPV devices is the design of well-performing electrodes with low cost of deposition. This has been one of the focus of the academic and industrial community. Nowadays, the use of ITO as a semitransparent electrode has become a bottleneck. This is because it is brittle, has Indium (a rare element), and needs a high energy intensive deposition process. There are many alternatives presented but none of them match the performance of ITO. Here, we report a full solution-processed ITO-free semitransparent OPV device based on silver nanowires (Ag NWs). To demonstrate the potential of Ag NWs in OPV devices, they were employed as a bottom and top electrode without a post treatment to decrease their roughness. Record devices achieved only a decrease of 6.5% of efficiency in comparison to ITO based reference devices. Furthermore, due to its good bending properties, a working stretchable device was fabricated by depositing the different OPV layers on a pre-stretched elastomeric membrane. These results indicate that Ag NWs can successfully replace ITO as an electrode.Sustainable Energy TechnologyPhotovoltaic Materials and DevicesElectrical Engineering, Mathematics and Computer Scienc
Strategic Design of Multi-Actor Nascent Energy and Industrial Infrastructure Networks under Uncertainty
No full textInfrastructure networks, such as gas transmission and distribution pipelines, electricity transmission and distribution cables, district heating networks and carbon capture and storage pipeline networks are vital infrastructures that form the backbone of our energy system. They transport commodities (i.e. gas, hot water, electricity) from one or several sources to one or several consumption/conversion sites through dedicated pipelines and cables. These infrastructure networks are undergoing major changes due to an increasing integration of renewable sources in the energy sector and increasing adoption of CO2 emission reduction measures by carbon intensive industries. For instance, the topology of the electricity network is undergoing changes to accommodate distributed power generation and the flexibility of consumers. Likewise, new pipeline infrastructures are being deployed for transporting CO2 from industrial sources to storage sites and greenhouses. This thesis focuses on the design of nascent energy and industrial infrastructure networks: networks that still needed to be built and for which neither scope, size, nor participants were certain. It develops systematic design analysis approaches to help improve design under uncertainty by means of flexibility. There are four parts to the thesis. The first part focuses on understanding the concept of flexible design and its application to the design of engineering systems and energy infrastructure networks. The second part focuses on flexibility analysis with the objective of improving their lifetime performance in the face of uncertain design requirements. A systematic engineering design approach combining graph theory network modelling, exploratory modelling and real options is proposed to explore candidate designs, identify valuable flexibility enablers and appreciate the value of flexible design strategies. The third part considers the role of risk sharing when actors co-invest in infrastructure networks under uncertain environment. Contractual arrangements are modelled between actors as a cooperative game and analyses the effects of uncertainty. The fourth part focuses on how private and public actors may enhance desired performances when developing new energy and industrial infrastructure networks under uncertainty.The Doctoral Degrees issued upon completion of the programme are issued by Comillas Pontifical University, Delft University of Technology and KTH Royal Institute of Technology.

Precision measurement of the neutron spin dependent structure functions
No full textIn experiment E154 at the Stanford Linear Accelerator Center the spin dependent structure function g{sub 1}{sup n} (x, Q{sup 2}) of the neutron was measured by scattering longitudinally polarized 48.3 GeV electrons off a longitudinally polarized {sup 3}He target. The high beam energy allowed the author to extend the kinematic coverage compared to the previous SLAC experiments to 0.014 {le} x {le} 0.7 with an average Q{sup 2} of 5 GeV{sup 2}. The author reports the integral of the spin dependent structure function in the measured range to be {integral}{sub 0.014}{sup 0.7} dx g{sub 1}{sup n}(x, 5 GeV{sup 2}) = {minus}0.036 {+-} 0.004(stat.) {+-} 0.005(syst.). The author observes relatively large values of g{sub 1}{sup n} at low x that call into question the reliability of data extrapolation to x {r_arrow} 0. Such divergent behavior disagrees with predictions of the conventional Regge theory, but is qualitatively explained by perturbative QCD. The author performs a Next-to-Leading Order perturbative QCD analysis of the world data on the nucleon spin dependent structure functions g{sub 1}{sup p} and g{sub 1}{sup n} paying careful attention to the experimental and theoretical uncertainties. Using the parameterizations of the helicity-dependent parton distributions obtained in the analysis, the author evolves the data to Q{sup 2} = 5 GeV{sup 2}, determines the first moments of the polarized structure functions of the proton and neutron, and finds agreement with the Bjorken sum rule

Post-Exodus or the involuntary prisoners of architecture
No full textPost-Exodus or the involuntary prisoners of Architecture, is a project about corrupt well intended top-down pretentions. A project about when utopia becomes dystopia. About when the built environment becomes out of tune with experienced and desired reality. Accumulating to the point of large scale vacancy and crisis. The focus of the project will be the case of the Kleiburg flat, the last untouched piece of Bijlmer ideology. The project was done in the graduation lab 'Design as Politics' with the underlying theme 'In the Ghetto', in which a personal view on the definition of a ghetto was encouraged. In this project the ghetto is described as an urban area that resonates with negative associations, as a segregated area often associated with the social-economic-weaker section. Due to the unpopularity of the urban area, real-estate values drop, investors and project-developers stay away. Conditions deteriorate. For those who want to leave the ghetto but can not afford to do so, the ghetto becomes an urban prison. The title of the project plays with the idea of architecture's ability to manifest dreams and desires. As the exodus took place and people moved towards the better, they left behind the old. The exodus was for those who could afford to leave; those unable to escape the undesired urban conditions where left behind. Post-Exodus focuses on these deprived areas, on these places of undesired architecture. It searches how to become a desired place once again, even when the means are limited. The research investigates a South-American Prison situated in Bolivia, in the capital city of La Paz. In the old city center, on the old colonial spanish grid the prison of San Pedro stands. Hidden behind the stucco walls, upon passing the guarded gate, a unexpected vivid community is revealed; the self-regulating inmate population of San Pedro. The prison was inspired by the panopticon model (Pentonville, London) of Jeremy Bentham. Built around the nineteen hundreds, this ideological prison model proved to be one of unrealistic utopia. The penitentiary system could not live up to the build expectations. The conditions of the inmate population deteriorated inside the prison walls. Without a welfare state or governmental subsidies the prisoners where appointed to their own ability to take matters into their own hands. Escape was not an option, the solution had to come from within... The do-it-yourself attitude of the prisoners resulted in an unique bottom-up transformation of the old prison model. Over time the prisoners slowly adapted the building to fit their basic needs, constantly fighting for their rights and defending every square inch. They held no nostalgia of the past, adapting to the new reality of their needs, adapting the build environment at best to survive. Over time San Pedro Prison developed its own logic, a mini-society with its own micro-economy, micro-policies, democratic elections, a prison real-estate market, cafes, restaurants, fitness area, sauna's, pool halls, tv corners, shops, dentist, churches, ceremony square, football competitions, tourism, workplaces, jobs and even more.. The San Pedro Prison inspires to look in a different way at the built environment we inhabit. It inspires to think in a different way about our attitude towards buildings. It inspires to think in a different way about architecture. It inspires to see how in the worst conceivable conditions, the prisoners of San Pedro where able to transform their built environment into a more favorable condition, to suit their lives and needs better. Transformation as a continues process, attuning to the ever changing times. Kleiburg is dead, it's ideology faded in the face of reality. Time has changed, Kleiburg stood still. If Kleiburg is not to parish in irrelevance it must once more become a part of our dreams and desires. Emergent societal trends and changes must then form the basis of its transformation. In times of financial crisis, unpredictability and uncertainty the means are limited. The answers must not be sought in the top-down financial power of big project developers but in the power of the ordinary people; the power of the people dwelling and working in and around Kleiburg. The design investigates a bottom-up approach, a do-it-yourself attitude, a gradual growth towards a new future. To clarify such a development a scenario was written in which the existing local social and urban fabric where extrapolated into the Kleiburg building. The initial conditions are dictated by the structural possibilities of the Kleiburg flat itself. The installation of the 'Gate' marks the presence of an underlying democratic process. Spatial hierarchy determines the relationship of space and influence of individuals/collectives on the built environment. In a set of projects possibilities are designed, each design telling a different story, each story exploring a new theme, each theme adding to a bigger scale. By the time we look back at all the different designs we will witness the emergence of museum. A Bottom-Up-Museum symbolizing the deconstruction of the prestigious 'starchitect' object, reconstructed by ordinary people.Design as PoliticsArchitectureArchitectur
