The integration of functional materials into electronic devices has become a key approach to extending Moore’s law by increasing the functional density of electronic circuits. Here, we present a device technology based on ultrascaled ferroelectric, antiambipolar transistors (ferro-AAT) with robust negative transconductance, enabling a wide range of reconfigurable functionalities with applications

Traumatic brain injury (TBI) is a major cause of morbidity and mortality, not least in the elderly. The incidence of aged TBI patients has increased dramatically during the last decades. High age is a highly negative prognostic factor in TBI, and pharmacological treatment options are lacking. We used the controlled cortical impact (CCI) TBI model in 23-month-old male and female mice and analyzed t

Based on the DCV-C60 system of fullerene acceptor organic solar cell active materials, the charge transfer process of D-A type molecular materials under the action of an external electric field (Fext) was explored. Within the range of electric field application, the excited state characteristics exhibit certain regular changes. Based on reducing the excitation energy, the excitation mode shows a t

LTx remains the definitive treatment for end-stage lung disease, but the increasing demand for donor lungs outpaces the available supply. This chapter explores innovative approaches to expand the pool of viable donor lungs and reduce waiting times, which is crucial to lowering mortality rates among patients on transplant lists. Xenotransplantation, which has made its greatest strides using porcine

The field of organ transplantation is experiencing a transformative shift with the rise of Advanced Therapy Medicinal Products (ATMPs), which include gene therapies, somatic cell therapies, and tissue-engineered products. These therapies offer new, potentially curative treatments for longstanding medical challenges, impacting numerous patients. However, their adoption is hindered by complex regula

As advancements in transplantation techniques continue, the challenge remains the limited availability of suitable donor organs. This chapter explores strategies to expand the donor pool and optimise transplant outcomes, which include the use of extended criteria donors, living lobar transplantation, donor-to-recipient graft size matching, and innovations in hypothermic storage and ex vivo lung pe

This study is an explorative examination of changes in employment, revenue, and firm structure for low, mid, and high-skill firms in urban and rural areas in Sweden from 2007 to 2019, using skill groups based on education levels. For employment in Sweden in general, we find evidence of job upgrading. In the city of Stockholm we also document job polarization in the sense that employment in both lo

Supported lipid bilayers (SLBs), formed via lipid vesicle adsorption on highly curved silica surfaces, are widely used in biosensor applications and as models for curved cell membranes. However, SLB formation is often hindered on convex structures with radii comparable to the vesicles. In this study, lightguiding semiconductor nanowires (NWs), engineered for fluorescence signal enhancement, were u

Extracellular vesicles (EVs) carry biological information from their parent cell to other cells in the body. To intercept and decipher this information necessitates the isolation of EVs from complex backgrounds such as blood or spinal fluid. Acoustic trapping has been previously demonstrated as a promising technique for EV isolation from cell media, blood plasma and urine. The acoustic fields stru

We present an operando study where Ambient-Pressure X-ray Photoelectron Spectroscopy (AP-XPS), Polarization Modulation-InfraRed Reflection Absorption Spectroscopy (PM-IRRAS) and Mass Spectrometry (MS) were employed simultaneously with sub-minute time resolution to monitor the CO oxidation and NO reduction reactions on Rh(111). AP-XPS is a powerful tool to follow reactions at the surface-gas interf

We present a novel acoustofluidic chromatography platform for high-throughput nanoparticle trapping and enrichment, with a focus on extracellular vesicles (EVs) from blood plasma. The system features a packed bed of polystyrene beads inside a rectangular glass capillary, acoustically actuated by a piezoelectric element. Using fluorescent polystyrene nanoparticles as small as 25 nm, we characterize

Lead-free metal halide perovskites are emerging as less-toxic alternatives to their lead-based counterparts. However, their applicability in optoelectronic devices is limited, and the charge transport dynamics remain poorly understood. Understanding photo-induced charge and structural dynamics is critical for unlocking the potential of these novel systems. In this work, ultrafast optical and Raman

Electron paramagnetic resonance of Cr3+ ions in β -Ga2O3 is investigated using terahertz spectroscopic ellipsometry under magnetic field sweeping, a technique that enables the polarization resolving capabilities of ellipsometry for magnetic resonance measurements. We employed a single-crystal chromium-doped β -Ga2O3 sample, grown by the Czochralski method, and performed ellipsometry measurements a

X-ray fluorescence emission spectroscopy is a powerful tool to gain chemical information on a wide variety of samples. Its combination with focused X-ray beams and translation stages enables X-ray fluorescence microscopy, generating quantitative distribution maps for sets of chemical elements, depending on incident photon energy and detector specifications. The use of synchrotron radiation for X-r

Background: The European Union recently recommended evaluation of the feasibility of organised prostate cancer screening. In Sweden, regional population-based organised prostate cancer testing (OPT) programmes were introduced in 2020. Objective: To describe initial participation rates and diagnostic outcomes. Design, setting, and participants: The three most populated Swedish regions invited all m

In recent years the concept of “Blue carbon” has brought attention to the importance of Mangroves, Seagrass and Saltmarsh ecosystems in carbon cycles. Concerns over climate change has had countries commit to decreasing CO2 emissions, often using natural processes to sequester CO2. This trend has often followed a market approach through creating a monetary value and market for CO2. This Climate Fin

I början av 2018 utbröt en debatt om kulturrådets utdelning av litteraturstöd i svenska dagstidningar. I samband med uttalanden från kulturminister Alice Bah Kuhnke menade vissa av bokmarknadens aktörer att litteraturstödet är utsatt för politisk styrning och att kvalitetskriteriet bortprioriteras. Uppsatsen undersöker de olika förväntningarna och föreställningarna som finns på litteraturstödet. J

The Fundamental Review of the Trading Book sets the standard for the most recent regulatory framework for minimum capital requirement within market risk. It will be implemented gradually up until 2019 and will overhaul a major part of the current regulation. More specifically it will cause financial institutions to estimate risk with Expected Shortfall instead of Value-at-Risk and add a new way of

I folkrättsligt hänseende är en stat endast skyldig att låta de egna medborgarna uppehålla sig på dess territorium. Ur ett EU-rättsligt perspektiv är dock varje medlemsstat förpliktad att tillämpa de regler som avser främja fri rörlighet för personer inom unionen. Dessa återfinns i EU:s primärrättsliga stadganden men konkretiseras genom sekundärrättsliga bestämmelser, framförallt genom direktiv 20With regard to international law, a state is only required to allow its citizens to reside within its own territory. However, from an EU law perspective, each Member State is obliged to apply regulations which intend to facilitate the free movement of persons within the EU. This is expressly laid down in the EU treaties, but must be viewed within the context of secondary law, in particular, the Ci
