Donor-acceptor (D-A) copolymers typically show two absorption peaks in the visible region, flanking a valley region of limited absorptivity. One strategy for more panchromatic light harvesting is to incorporate side-groups orthogonal to the polymer backbone, which enable 2D π conjugation and can give rise to additional absorption peaks. Here we design and synthesize two D-A polymers which both car

The development of future 3D-printed electronics relies on the access to highly conductive inexpensive materials that are printable at low temperatures (<100 C). The implementation of available materials for these applications are, however, still limited by issues related to cost and printing quality. Here, we report on the simple hydrothermal growth of novel nanocomposites that are well suited fo

Hypothesis: Previous works have shown that many-body interactions induced by dispersants with increasing correlation length will generate a diminishing two-phase region [Soft Matter 14, 6921 (2018)]. We conjecture that the attenuation of the depletion attraction due to many-body interactions is a ubiquitous phenomenon in medium-induced interactions. We propose mixtures of colloidal particles and r

Only for three of the known defects in the metabolism of the amino acidsGABA, glycine, serine, and proline has a more-or-less efficient treatment been reported: the GABA catabolic defect, succinic semialdehyde dehydrogenase deficiency (vigabatrin, causing substrate depletion by inhibition of GABA transaminase); the glycine catabolic defect, nonketotic hyperglycinemia (diet combined with benzoate a

Cell physiology and cellular responses to external stimuli are partly controlled through protein binding, localization, and expression level. Thus, quantification of these processes is pivotal in understanding cellular biology and disease pathophysiology. However, it can be methodologically challenging. Immunofluorescence is a powerful technique, yet quantification by this method can be hampered b

Measuring fibre dispersion in white matter with diffusion magnetic resonance imaging (MRI) is limited by an inherent degeneracy between fibre dispersion and microscopic diffusion anisotropy (i.e., the diffusion anisotropy expected for a single fibre orientation). This means that estimates of fibre dispersion rely on strong assumptions, such as constant microscopic anisotropy throughout the white m

We studied sediments from the ca. 1400 million-year-old Xiamaling Formation from the North China block. The upper unit of this formation (unit 1) deposited mostly below storm wave base and contains alternating black and green-gray shales with very distinct geochemical characteristics. The black shales are enriched in redox-sensitive trace metals, have high concentrations of total organic carbon (T

The development of good writing skills is fundamental not only to publish scientific results, but also to have a deeper understanding of complex subjects. However reports from the Swedish Higher Education Authority from 2012-2015 suggest that engineering students at Lund University have unsatisfactory academic writing skills. Our paper investigates how students of the Faculty of Engineering at Lun

Design of discontinuity regions in reinforced concrete is today often performed with Strut and Tie Method (STM) or linear finite element analyses (LFEA). However, it is questionable to what extent these design methods are appropriate with regard to resistance, ductility, serviceability and economic reinforcement arrangement. In design with STM a simple equilibrium model based on plasticity theory

Satellites are key components in today's modern world, but they are expensive to launch and the orbits are crowded. With use of a dual band circular polarization selective structure (CPSS) the satellites can be improved and the number of reflectors needed to carry out a certain task can be reduced. A dual band CPSS reflects one handedness of circular polarization and transmits the other, over

Den engelska professorn och filosofen Roger Scruton har under ett långt akademiskt liv kritiserat samtiden på många olika sätt. Han är kritisk till det postmoderna samhället och filosofer som Focault, Derrida och Habermas. Han menar att den västerländska kulturen idag står under hot. Syftet med denna uppsats är därför att redogöra för och kritisk diskutera Scrutons analys och kritik av det västerlThe English professor and philosopher Roger Scruton has in a long academic life criticized contemporaries in many different ways. He is critical of the post-modern society and philosophers as Focault, Derrida and Habermas. He believes that Western culture today is under threat. The purpose of this bachelor's degree project is to describe and discuss critical Scrutons analysis and criticism of

ChemCo is a high quality producer in the speciality chemical market, a market characterised by complex production and high variability. With limited system-support and limited data quality, delivery accuracy suffered, and so did production efficiency. ChemCo believed that this was due to poor lead-time performance, why they wished to research the problem. Research on setting lead-times has focused

Vardagliga ting, så som detta papper, är sammanställt av vanlig materia. Det vi ser med våra ögon och genom teleskop när vi tittar upp mot stjärnorna är också sammanställt utav vanlig materia. Det visar sig att denna materia endast fyller vårt kända universum till 5 %. Resten kallas för Mörk Materia och Mörk Energi, där den föregående fyller universum med 27 % och den snarare till 68 %. Mörk MaterIn this thesis, I present a case where Dark Matter subhalos would annihilate at some stage in their lifetime. The implication of this scenario could potentially aid the Missing Satellites and the Cusp-Core density profile problem. The Dark Matter particles’ annihilation process and effective “friction” lead to an energy and momentum loss into radiation and hence to the destabilization of the Dark

Uppsatsen syftade till att skapa och testa ett enkelt verktyg att använda inom organisationer för att öka anställdas välbefinnande och förbättra upplevelsen av psykologiska, sociala och organisatoriska arbetsförhållanden. Med teoretisk utgångspunkt i positiv psykologi skapades en tre veckor lång arbetsplatsintervention. De 32 deltagarna var administrativ personal hos en politisk organisation indel

This thesis explores the right to access employment for persons with disabilities under the UN Convention on the Rights of Persons with Disabilities. It seeks to ascertain what entitlements and for whom this right entails. Given the central conceptual role disability and equality play in the Convention, this thesis explores the prevailing models of understanding of both disability and equality. Af
