Morphology, structure and chemistry have been investigated for 17 different commercial graphenegrades,all labeled as different kinds of graphene powder. For objectivity reasons, all powders have been given names as Graphene A-Q instead of their real product names. Out of the 17 tested powders, only Graphene A and B showed consistent results of being graphene-like. All powders have been characteriz
Vätgas har potential i ett energilagringssystem eftersom det är en energibärare som är väldigt energirik och kan lagras i stor skala. Vätgas kan produceras enkelt via elektrolys av vatten och lagras i stora mängd under högt tryck, vid behov kan vätgasen sedan brännas i en kraftverksprocess och generera elektricitet. Då förbränning av vätgas med syrgas enbart bildar vattenånga kan ett förnybart eneHydrogen gas has potential to function as an energy storage solution due to its high energy content and its suitability for large scale storage. Hydrogen can be produced by water electrolysis and can be stored in large scale under high pressure, when needed the hydrogen can be burned in a thermal power plant to generate electricity. Since combustion of hydrogen with pure oxygen only yields steam,
In the peak of the 2015 refugee crisis, Sweden stipulated a new law in order to give the system respite while recovering from the pressure that followed from the 162 877 asylum applications Sweden received that year. The Act (2016:752) on temporary limitations of the opportunity to be granted residence permit in Sweden entered to force on 19 July 2016 to apply for three years. The law constitution

Each year around 3.9 million girls around the world are victims to female genital mutilation/cutting. This custom is often a consequence of traditional, social and cultural norms within a society. In Sweden, female genital mutilation/cutting is illegal and punishable by law, and professionals have obligations to report if there is suspicion that a girl either is, or is at risk of being genitally m
It is necessary for all industries to work actively to minimize their impact on the climate, including the construction industry, which accounts for a significant part of Sweden's total CO_2-emissions. Development to produce concrete and steel with more environmentally friendly processes is ongoing, but to lower emissions immediately and achieve long-term sustainability, we need to develop met
The aim of this thesis was to compare different ways of dissociating tissue - specifically breast cancer tissue - and sorting out tumour cells and immune cells from the dissociated tissue using acoustophoresis in a microfluidic chip. Due to ethical issues with using tumour tissues to work on the methodology of a project, ultimately only healthy breast tissue was used in this work. Two dissociatio
As the clock ticks on our opportunity to limit catastrophic climate change, mitigation efforts are becoming increasingly essential, especially amongst countries with high current or historic emissions. However, these mitigation attempts are not a guaranteed success, especially when the system within which they operate is not understood due to unacknowledged bias in quantitative data. As such, wick
There is a growing shift in environmental management tools from the traditional command and control approach to market mechanisms where environmental goods and services are assigned market values to generate incentives for environmental protection. In November 2007, the Sabah state government announced a joint venture with New Forests Pty. Ltd. to set up a Wildlife Conservation Bank at Malua Fores
Context: Today, 96% of Sweden’s materials come from virgin resources and only 3.4% of resources used in Sweden are retained in the value chain. From a total of 266 million tonnes fed into the economy each year, 46.9% consist of construction materials. Hence, there is a need to adapt circular strategies, such as reuse of construction products, to meet Sweden’s goal of becoming net zero by the year

In recent years, microwave applications in the food products have attracted increasing attention by the food packaging industry and the consumers due to their convenience, low energy and water usage and short processing time giving them a sustainable advantage over competing technologies. In-pack pasteurization represents one of the fastest developing technologies in preparing and delivering safe
Speech has become an increasingly important source of non-invasive information for Parkinson's disease detection, but much existing work still relies on sustained vowels. This thesis investigates whether carefully represented continuous speech can provide added predictive value over a strong sustained-vowel benchmark. Using the NeuroVoz corpus, sustained-vowel recordings were first used to est
Metal additive manufacturing is a rapidly emerging technology, with a growing number of companies interested in its implementation. The technology can have several positive effects, such as more efficient production, reduced transports, more focus on circular economy and reduced costs. However, the manufacturing process is still relatively slow, where components require extensive post-processing a

Justitiedepartementet publicerade ett utkast till lagrådsremiss den 24 september 2025 som kompletterar SOU 2025:11 där det föreslås att straffbarhetsåldern i Sverige ska sänkas till 13 år vid allvarliga brott. FN:s barnrättskommitté har i sina allmänna kommentarer uppmuntrat Sverige att behålla straffbarhetsåldern på 15 år samt uttalat att de anser att system med undantag från den standardiserade On the 24th of September 2025, the Ministry of justice in Sweden published a draft legislative referral that supplements SOU 2025:11, which proposes lowering the age of criminal responsibility to 13 years for serious offences. The CRC has, in its general comments, encouraged Sweden to maintain the age of criminal responsibility at 15 years. They have also stated that systems allowing exceptions t
Introduction: Molecular oxygen is the most common oxidizer in nature. Since it has been part of evolution, it is heavily incorporated into biological systems, the most significant being cellular respiration, glycolysis, and the citric acid cycle. Luckily, molecular oxygen can also be used as an oxidizer in the lab, and with the right conditions, to generate 1,2-dicarbonyl compounds. Background
Förenta nationernas konvention om barns rättigheter gäller sedan 1 januari 2020 som lag i Sverige. Strax därefter inleds något som kallats ”LVU-kampanjen” och övriga aktörer som demonstrerar mot socialnämndens beslut om tvångsvård av barn har på senare tid också fått stor uppmärksamhet. Jag funderar därför på om inkorporeringen av barnkonventionen har påverkat lag (1990:52) med särskilda bestämmelThe United Nations Convention on the Rights of the Child (CRC) has been in force as law since 1 January 2020 in Sweden. Soon after, something called the "LVU-campaign" was launched, and other actors who demonstrate against the social welfare board's decision on forced care of children have recently also received a lot of attention. I am therefore curious about whether the incorporati
The purpose of this study is to map Key Performance Indicators (KPIs) related to the operation and maintenance of photovoltaic (PV) systems, i.e., solar cells, on commercial buildings. This is investigated through a literature review aimed at gathering and evaluating relevant KPIs. A total of 24 KPIs are identified in the literature review. After evaluation, a selection of these KPIs is used to an
