A molecular level understanding of the structural reorganization accompanying interfacial electron transfer is important for rational design of solar cells. Here we have applied XTA (X-ray transient absorption) spectroscopy to study transient structures in a heterogeneous interfacial system mimicking the charge separation process in dye-sensitized solar cell (DSSC) with Ru(dcbpy)(2)(NCS)(2) (RuN3)

We report on fabrication and optical characterization of GaAs nanopillar (NP) arrays, obtained using a combination of low-cost mask generation by self-assembled silica particles (nanosphere lithography) and dry etching. Tapered structures (conical and frustum NP arrays) are fabricated by appropriate optimization of process parameters. Significant suppression of surface reflectance is observed for

This study aims to investigate how consumers perceive variety in grocery stores and further how private brands have affected consumers’ perceptions of variety in grocery stores.The study focuses on the perceptions and attitudes towards variety and the impact of private brands on perceived variety. Hence, a qualitative rather than quantitative study has been used. Photo elicitation has been used in

Problem statement This master thesis was initiated since today, when developing a new mobile phone at Sony Ericsson, it is difficult to get a perception of the ergonomics and the tactility of the keyboard before the first design prototype (DP0 and DP1) is built. The SLA block model used today is completely solid and consequently a secured decision of the final design can not be made in this phase

Our master thesis is performed for Faiveley Transport AB, Landskrona. The company’s main business area is development and assembly of complete brake systems, wheels and couplings for railway vehicles. The company is currently working on a project, V-Brake, to develop a new competitive brake. Earlier two students, T. Persson and J. Mårtensson, have been working with the development of the brake, bu

The transition from care to independent living is a critical period in the lives of young people leaving residential care. The purpose of this study was to find out what young people leaving residential care need for a successful re-adaptation to society. Another purpose was to find out from research the essential factors for good outcomes to last after residential care. In order to find out I con

Corruption is at present costing the European society enormously amounts, in forms of money and in relation to social, economic, political and legal development. Democracy is viewed as one of the fundamental pillars of the European Union, which additionally has been one of the Union’s highest priorities since its foundation. One aspect that may be hindering the increasing of democracy is a state’s

The main research problem in this thesis is the lack of a holistic understanding of how neo-patrimonialism, colonial legacies, decentralisation, illiberal peace-building and the revitalisation of traditional reconciliation practices have affected conflict, peace and development in North Maluku Province (NMP). This is important to study, given the negative impacts inherent in the conflict-developme

Despite the increased focus on sustainable urban development both within academia and in urban planning practices, authors seem to agree that we are mostly continuing business as usual and are not embarking on different socio-environmental trajectories. On the contrary, such urban sustainability practices can often lead to processes of displacement and gentrification, thus worsening the conditions

Following trends in local and global environments, it is obvious that many companies are faced with difficulties to survive in this competitive environment. Business Model Innovation (BMI) is the key to the firm’s long-term success. The case study of BTC d.d., has been made to give an example how firms should be aware of their weaknesses and strengths in order to constantly innovate their business

Following the recent resurgence of capitalism as a key subject in historical analysis, historians have highlighted the globally interconnected making and remaking of capitalism. Commodity-centred histories in global history have shown how to write locally grounded histories of global capitalism emphasising the complex and contingent relationship between the local and the global. In these accounts,

The recent surge in publications on the history of knowledge may obscure the fact that there are several parallel understandings of what the field is. In this article, I discern five major historiographical directions in contemporary scholarship regarding the history of knowledge. The analytical framework that has so far attracted the most attention is the circulation of knowledge. As productive a

The impact of cyberbullying on mental health is a significant concern among adolescents, yet there is limited research on the neurophysiological markers of cyberbullying. This study aims to address this by exploring whether resting state electroencephalography (EEG) power, among traditional frequency bands (delta, theta, alpha, beta), predicts cyberbullying experiences over time. Participants (N =

In 2001 the Doha Round Talks was initiated by the World Trade Organization. Development was the overarching goal. For several developing countries with a comparative advantage in agriculture, trade with such products is seen as essential to economic growth and thus development. In order to spur this development it appears to be particularly important that developing countries have increased access

The purpose of this thesis was to study descriptions of companies on their webpages on the Internet. This was performed from a socialconstructionist point of view with focus being on subject positionings and gender. A critical discourse analysis was carried out on two texts from the webpages of two organizations on the Internet. Using the three dimensional model for critical discourse analysis by

This study examines the roles of transitional justice and reconciliation in post-conflict societies and the relationship between these two concepts. There seem to be a widespread pessimism regarding the possibility of combining these two concepts in a post-conflict situation due to what is described as a fundamental tension between justice and reconciliation. However, I find that the connection an

This thesis aims to explore the relevance of identities for the support of democracy in Ukraine. It elaborates on the assumption that the identity's construction affects which ideas are embraced and sets out to test whether a civic as opposed to ethnic identity construction would correlate with the embracing and pursuit of the idea of democracy. Material gathered during a Minor Field Study - i

Millimeter-wave cellular communication requires beamforming procedures that enable alignment of the transmitter and receiver beams as the user equipment (UE) moves. For efficient beam tracking it is advantageous to classify users according to their traffic and mobility patterns. Research to date has demonstrated efficient ways of machine learning based UE classification. Although different machine

A popular model for social evolution in the Santa Barbara Channel region holds that, during times of resource stress, islanders would trade with mainlanders for plant foods in order to supplement island diets. Recently, western sea-purslane (Sesuvium verrucosum) has been suggested as a primary food product involved in this exchange. This report presents new caloric values for Sesuvium verrucosum a
