Katalysatorer har många funktioner och applikationer, till exempel som enzymer i vår kropp eller katalysatorer i bilar. En katalysator är helt enkelt en substans som sänker den energi som krävs för att en kemisk reaktion ska ske och därmed öka reaktionshastigheten. Själva katalysatorn förbrukas inte under reaktionen. Inte alla katalysatorer hjälper alla reaktioner, olika katalysatorer har olika anA model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. Two coverages of 2 ML and 0:33 ML V/ anatase TiO2 and the oxida

Purpose: The purpose of our work is to gain a deeper understanding of the phenomenon of “quiet quitting”. We aim to challenge its various manifestations and question the existing diversity in definitions by examining different work behaviours of quiet quitting. In addition, we examine the reasons, while paying particular attention to the supervisor-subordinate relationship. Methodology: This study

The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. The study presents a suitability analysis using GIS to find potential locations for blue-mussel farm establishment, and the outcome was produced as maps. A mul

Human shields have been increasingly documented in contemporary theatres of war. In this context, it is interesting to examine the circumstances in which the attacking party classifies the civilians they face as human shields. Therefore, this thesis focuses on the use of the classification of human shields by belligerents facing civilians during armed conflicts. The paper sets forth the argument t

Behovet av lösningsmedel som kan byta ut farliga organiska eller fossil-baserade lösningsmedel har uppstått för att minimera utsläpp av farliga restprodukter. En lösning till detta behov är att istället använda vatten. Vad man har hittat är att vissa rektioner i vatten kan sker snabbare än i organiska lösningsmedel. Att byta ut lösningsmedel är inte den enda lösningen på att minimera slöseri i kemThe effect that organic solvents have on the environment and the intrinsic risk that come with using them should be limited. By replacing organic solvents with less harmful solvents, such as water, and with more effective catalysts can risks intrinsic to organic solvents be minimized or eliminated. The focus of this project is testing if Michael addition using transition metal salt catalysts with

This research paper examines the European Union's merger control regime and its efficacy in addressing the killer acquisitions by big tech firms in the fast-evolving digital sphere. It investigates the legal framework, competition policy objectives, and more importantly the impact of the digital sector on EU competition policy. Furthermore, it critically analyses the killer acquisitions by

På grund av klimatkrisen och de minskade resurserna av fossila bränslen, accelereras sökandet efter gröna och förnybara energikällor. Vätgas är en av de bästa ersättningarna för fossila bränslen eftersom det enda biprodukten vi får vid förbränning är vatten. Dock är dess användning begränsad på grund av utmaningarna med att lagra och transportera vätgas. Den nya och framväxande teknologin för att Four pincer-ligated iridium complexes, 1-4, featuring substituents with different electronic properties on meta and para positions on the aromatic backbone were synthesized for the purpose of comparing their efficiency as catalysts in the acceptorless dehydrogenation of 1-phenylethanol. Previous studies have already revealed that turnover frequencies were higher in more dilute catalyst solutions,

Abstract This work is one of a series of related papers that were made in Lund University. They were done to analyze in a multi scalar way the Yttrium Orthosilicate crystals (YSO), analyzing the variation of material properties stemmed from the mounting, composition and other parameters in the optical properties of Yttrium Orthosilicate crystals. This paper specifically focused on investigating th

Nya studier visar på en ökad skuldsättning hos unga vuxna, framför allt unga kvinnor. Syftet med föreliggande studie var att undersöka sambandet mellan psykisk ohälsa, upplevd ensamhet, privatekonomisk situation, konsumtionsbeteende och användandet av sociala medier samt hur dessa skiljer sig i en köns- och generationskontext, men även hur interaktionen mellan dessa variabler ser ut. Detta utefterRecent studies show an increase in debt among young adults, especially young women. The purpose of this study was to examine the relationship between mental health, perceived loneliness, personal financial situation, consumer behavior, the use of social media and how these differ in a gender and generational context. A further aim was to study the interaction between these variables, based on prev

Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot. In particular, a two-dimensional phase pattern is retrieved and de
