A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes

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 widespread use of plastic mulch in agriculture is rapidly increasing due to intensified farming practices. While plastic mulch can enhance crop yields significantly, it also introduces challenges related to waste management and environmental degradation. This study focuses on the application of Sentinel-2A imagery and the Maximum Likelihood Classifier (MLC) to classify plastic foils used in ea

This thesis presents a case for the establishment of a human right to financial inclusion under the human rights framework, as well as argues for states to legitimize the right through legal protection in the form of a legislation in order to effectively guarantee the significant benefits of the right for everyone. The rationale for this research is that, despite its immense contribution in human

This thesis has investigated the potential of combining Raman spectroscopy with Sheimpflug Light Detection and Ranging (lidar) for simultaneous characterization and ranging of aerosolized soot. The first part of the project involved the implementation of conventional non-ranging Raman spectroscopy for both deposited and aerosolized soot. The second part constituted the design, modelling, and evalu

Background: Healthcare systems across the globe face challenges with staffing shortages and unsustainable expenditure, intensified by an aging population requiring more long-term care. Mixed home care, combining formal and informal care at home, is a growing market, where Internet of Medical Things (IoMT) solutions offer opportunities for efficiency and personalized care. Purpose: To identify, un

To decrease the dependency of fossil-based raw materials in society, and with that, the chemical industry, new and sustainable raw materials need to be investigated. Lignin is an abundant aromatic biopolymer, that can be used to produce, e.g. aromatic fine chemicals through depolymerization. In this master’s thesis, different homogeneous and heterogeneous catalysts were screened for oxidative depo

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

Till följd av senare tids debatt angående barns försämrade finmotoriska förmågor så har detta arbete som mål att sammankoppla detta med produktdesign och föreslår därmed tre koncept som kan användas för att utveckla barns finmotorik. Detta görs genom att först skapa en underliggande förståelse för finmotorisk förmåga och utveckling genom en explorativ litteraturstudie. Denna del av arbetet klargör

Glioblastoma is a highly aggressive brain tumor that kills roughly 9,000 Americans yearly. Although a known disease for over a century, little progress has been made in treatment development. A breakthrough may be on its way as recent research suggests glioblastoma patients can be treated with virus injections, oncolytic virotherapy in medical terms. However, this treatment method is somewhat inhi

The multifunctional cryogels were synthesized by atom transfer radical polymerization (ATRP) using hemoglobin as a biocatalyst (ATRPase) and post-modified to purify hemoglobin and glycoprotein simultaneously. Meanwhile, the optimization of purified glycoprotein was also conducted by introducing epoxy group nanoparticles. The nanoparticle concentrated concanavalin A, the ligand, to adsorb glycoprot

Introduction: Surgeons can reduce incisional hernia formation by adhering to standardized techniques for incisional wound closure. This is often neglected by the time a long operation is to be ended and can lead to the risk of developing an incisional hernia or a wound rupture. To address this issue, a suturing machine (Suture-TOOL) was developed for swift and standardized abdominal closure. The a

Optimising waste management is one of the key areas in sustainable development to protect public health and the environment. However, most countries are yet to achieve sustainable waste management due to increasing waste generation, limited landfill space, resource depletion, cost of recycling, public buy-in, etc. These challenges have resulted in poor waste management and environmental pollution

Well-planned evacuation is an effective and often necessary tool to protect life in communities threatened by wildfire. In previous incidents, community evacuations have been called too late resulting in entrapment, such as in Mati, Greece in 2018. The most reliable method to determine the safe time to call an evacuation is through trigger boundaries, perimeters on the landscape surrounding a comm

In X-ray macromolecular crystallography (MX), single-wavelength anomalous dispersion (SAD) and multi-wavelength anomalous dispersion (MAD) techniques are commonly used for obtaining experimental phases. For an MX synchrotron beamline to support SAD and MAD techniques it is a prerequisite to have a reliable, fast and well automated energy scan routine. This work reports on a continuous energy scan

Drought has negative impacts on water resources, food security, soil degradation, desertification and agricultural productivity. The meteorological and hydrological droughts prediction using standardized precipitation/runoff indices (SPI/SRI) is crucial for effective water resource management. In this study, we suggest ANFISWCA, an adaptive neuro-fuzzy inference system (ANFIS) optimized by the wat

Non-lethal infections are common in free-living animals and the associated sickness behaviours can impact crucial life-history trade-offs. However, little is known about the duration and extent of such sickness behaviours in free-living animals, and consequently how they affect life-history decisions. Here, free-living Eurasian blackbirds, Turdus merula, were immune-challenged with lipopolysacchar
