Utveckling och testning av reaktorer för katalysmätningar Katalysatorer är oumbärliga i såväl livsprocesser som industriella tillämpningar. Bilismen är ett exempel där katalysatorer används vid såväl bränsletillverkning som avgasrening. Men detta är långt ifrån det enda användningsområdet. Katalysatorer är också delaktiga i tillverkningen av uppemot 90% av alla kemikalier. Industriella katalysaIn this project four reactors for studies of heterogeneous catalysis have been developed. They were tested using case studies, especially concerning methane oxidation over palladium. The test measurements showed that the reactors work or would work very well after slight modifications. The first reactor allowed for activity measurement using mass spectrometry for temperatures up to at least 1000°C

I svenska kommuner används för tillfället ofta papperskartor som geografiskt hjälpmedel vid fältarbete. En mobil GIS (geografiskt informationssystem)applikation skulle kunna vara ett användbart hjälpmedel vid sådant fältarbete och speciellt för att genomföra fältinventering. I detta examensarbete har en sådan applikation utvecklas. Applikationen har utvecklats för Örebro kommun och kallas iSurvey.Currently, Swedish municipalities generally use paper maps to conduct field work. A Mobile GIS (geographical information system) application could be a useful tool when conducting field work and field inventory work. In this master thesis, such an application has been developed. The application was developed for the municipality in Örebro and is called iSurvey. When developing a mobile application

Popular science Carbon cycle has great importance in all time scales for its inter-connected relation and response with climate system. Increased anthropogenic emission of CO2 is alleged to impact the climate system in the future, which will affect the feedback between carbon cycle and climate change. In this project, a climate-carbon cycle feedback analysis has been conducted by using long simula

This degree project aims to develop standard methods for determination of the size distribution in different samples using laser diffraction, as well as to create methodologies for development of new methods for unknown samples. The size distribution is crucial to understand for pharmaceutical products since it affects properties such as the stability and bioavailability of the product. A way to

The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba

The thesis explores the decision-making process of sustainable entrepreneurs for securing external funds by adopting the “triple bottom line” research perspective (Hall et al., 2010; Sarango-Lalangui, 2018). It delves into how sustainable entrepreneurs assess and exploit funding opportunities while balancing their economic and non-economic goals. The research addresses two primary questions: what

The aim of this study was to deepen the understanding of how community-based water management approaches facilitate sustainable and collective action (SCA) in the context of increasing water insecurity in Costa Rica. Applying a qualitative approach, based on fieldwork in Guanacaste, Costa Rica, including semi-structured interviews and a digital community survey, the study uncovers facilitating fac

In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. The Swedish Research Council is supporting a project called Solar Food: Reducing Post-Harvest Losses Through Improved Solar Drying, which aims to create a low-cost solar

In recent years, battery energy storage systems (BESS) have gained prominence as a key technology enabling much needed electricity grid flexibility while simultaneously providing distinct value to its end-users. With the anticipated increase of residual value holding used batteries from mobility applications entering the market, more and more companies are looking to construct BESS offers around t

High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app

This thesis aims to explore the issue of trademark squatting and its solutions in the EU and China. Trademark squatting is a form of trademark infringement that occurs when individuals or entities register trademarks in territories where they do not have legitimate business operations, taking advantage of the "first-to-file" systems. If trademark squatting is permitted to persist, it has

Neutrons have a magnetic moment that interacts with magnetic fields. This has been put to use to study magnetic materials. Polarised neutron imaging (PNI) is one such application that allows the observation of, for instance, magnetic domains and domain walls inside a sample. To facilitate a PNI experiment, the neutron beam from a neutron source needs to be polarised, meaning that the magnetic mome

Innovationshöjden för automatiska skjutdörrssystem under de senaste årtionden har resulterat i högteknologiska automatiska skjutdörrar, där tillbehören och användargränssnitten inte har utvecklats i samma utsträckning. Det har lett till att programväljare för skjutdörrar blivit omoderna och svåranvända för användarna. Syftet med denna masteruppsats var att tillsammans med ASSA ABLOY Entrance SysteThe innovation of automatic sliding door systems over the past decades has resulted in high-tech automatic sliding doors, where accessories and user interfaces have not been developed to the same extent. As a result, operating mode selectors for sliding doors has become outdated and difficult for users to operate. The purpose of this master’s thesis was to propose a new design for operating mode s

Special hatha yoga classes for musicians and variations of postures (asana) in normal yoga classes. Why and how to apply the different branches of hatha yoga in a yoga class. Practicing breathing exercises (pranayama), concentration (dharana)/meditation (dhyana), postures (asana) and relaxation (savasana). Safe physical exercises without pressure/bodyweight on hands and wrists. I chose postures co

Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others. The range of exper

Med ökande koncentrationer av koldioxid (CO2) i atmosfären kan energieffektiva tekniker för koldioxidinfångning (CCS) bli viktiga för att växthusgasutsläppen ska minska. Rapportens syfte har varit att experimentellt bestämma och utvärdera fyra egenskaper hos lösningar av vatten, dimetylsulfoxid (DMSO) och aminoalkoholen 2-amino-2-metyl-1-propanol (AMP) som ska användas i en pilotanläggning. Vid inWith increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt cryst

In this thesis I examine how the aggressive fracking-debate in the Canadian Province New Brunswick from 2010 onwards, and how the three participating actors (the fracking-critical Native Canadian group Elsipogtog First Nation, the non-native fracking-critical group New Brunswick Anti-Shale Gas Alliance (NBASGA) and the fossil fuel company Southwestern Energy Resources Canada) view nature in differ

The presented thesis focuses on dynamics of capital structure decisions of financially constrained and unconstrained firms listed on Stockholm Stock Exchange. It examines the effect of the global financial crisis on the corporate financing decision. The first chapter introduces the topic, discusses its importance and outlines the contribution to the empirical research. The second chapter the relev
