Lithium-ion conducting molecular composites prepared by Yamamoto polymerization

Solid polymer electrolytes (SPEs) are promising alternatives to the flammable liquid electrolytes that are currently used in most commercial lithium-ion batteries. Because the transport of ions occurs through segmental motions of the polymer, ionic conductivity typically decreases as the mechanical strength of the SPE increases [1]. Much research has been devoted to the use of microphase separatio

Macromolecular design and synthesis of hydroxide conducting membranes with high alkaline stability

Today extensive research efforts are devoted to the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers that are able to operate efficiently without platinum group metal catalysts [1]. One of the great challenges is to design and synthesize polymeric AEM materials with high OH– conductivity and the necessary stability under

Molecular design of ether-free anion exchange membranes: effects on ion conductivity and alkaline stability

The development of durable and high-performance anion exchange membranes (AEMs) that allow production of inexpensive and efficient alkaline fuel cells and electrolyzers is currently attracting attention. These devices will work in tandem with environmentally friendly intermittent energy sources, such as solar and wind. Today, achieving both a high OH− conductivity and a sufficient stability at ele

Utilization of Andean grain flours in the development of wheat flour dough

Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelast

Free Ports for Art: Special Tax Zones as Cultural Policy Incentives?

A free port for art is a location in a country with purpose-built art facilities where imported works of art may be stored without taxes such as value added tax (VAT), goods and services tax (GST), consumption tax, transaction taxes and customs duties. As long as the art does not leave the free port, such taxes are not imposed, hence the word “free”. These free ports could be regarded as special t

Genetically Determined Risk of Depression and Functional Outcome After Ischemic Stroke

Background and Purpose- Psychosocial factors can have implications for ischemic stroke risk and recovery. This study investigated the effect of genetically determined risk of depression on these outcomes using the Mendelian randomization (MR) framework. Methods- Genetic instruments for risk of depression were identified in a discovery genome-wide association study of 246 363 cases and 561 190 cont

The Earth System Governance Project as a network organization : a critical assessment after ten years

The social sciences have engaged since the late 1980s in international collaborative programmes to study questions of sustainability and global change. This article offers an in-depth analysis of the largest long-standing social-science network in this field: the Earth System Governance Project. Originating as a core project of the former International Human Dimensions Programme on Global Environm

Translocalising and Relocalising Antifascist Struggles : From #KämpaShowan to #KämpaMalmö

This article explores the translocal hybrid activism surrounding two demonstrations triggered by a violent altercation between antifascists and neo‐Nazis in Malmö in March 2014. It maps the appearance and spread of the hashtag that underpinned this activism: #KämpaShowan. It also considers how the hashtag was articulated, adopted and adapted by different activists in ways that led to the emergenceThis article explores the translocal hybrid activism surrounding two demonstrations triggered by a violent altercation between antifascists and neo-Nazis in Malmö in March 2014.

Rapport från förtätad förort : Fältanteckningar från Norra Fäladen, Lund.

Den idag helt dominerande idén om den täta staden har en rad olika uttryck. Även i miljonprogramsområden får förtätningsprojekt olika effekt beroende på specifika omständigheter, inte minst hur förtätningar samverkar med andra större stadsomvandlingsprojekt—såsom storskaliga renoveringar av hyreshusbestånd och privatisering—och rent materiella utvecklingslinjer såsom ökad bostadsbrist, trångboddhe

Electronic structure of boron doped hopg : Selective observation of carbon and trace dope boron by means of x-ray emission and absorption spectroscopy

We have measured the soft X-ray absorption and emission spectra of near B-K and C-K absorption edges of highly oriented pyrolytic graphite (HOPG) doped with a small amount (0.32 at.%) of boron (B), including incident/takeoff angle dependence.The main peak intensities at the B-K edge around 182 eV were almost independent on the change of takeoff angle. On the other hand, the satellite peak around 1

Probes and Sensors: The Design of Feedback Loops for Usability Improvements

The importance of user-centric design methods in the design of programming tools is now well accepted. These methods depend on creating a feedback loop between the designers and their users, providing data about developers, their needs and behaviour gathered through various means. These include controlled experiments, field observations, as well as analytical frameworks. However, whilst there have

Measurement of distributions sensitive to the underlying event in inclusive Z boson production in pp collisions at √s = 13 TeV with the ATLAS detector

This paper presents measurements of charged-particle distributions sensitive to the properties of the underlying event in events containing a Z boson decaying into a muon pair. The data were obtained using the ATLAS detector at the LHC in proton–proton collisions at a centre-of-mass energy of 13 Te with an integrated luminosity of 3.2fb-1. Distributions of the charged-particle multiplicity and of

Triple-path collector optics for grazing incident x-ray emission spectrometer

A new type of collector optics was developed for grazing incident x-ray emission spectrometer. The collector optics used two cylindrical mirrors to add two extra light paths while keeping the center light path that directly illuminates the grating. The design and properties of the spectrometer using the triple-path collector optics were evaluated using ray-tracing simulations, and validity of this

Avtalsviten : effekter och rättsverkningar

This thesis concerns the legal consequences and the economic effects of the use of a damages clause (avtalsvite). Starting from a rather routinely picture in the legal literature, the thesis seeks to establish a more sophisticated application of the clause, in order to maximize the parties total utility.Thanks to their long-standing use, there is a generally accepted picture of what damages clauseThis thesis concerns the legal consequences and the economic effects of the use of a damages clause (avtalsvite).
