Technological and scientific advancements over the past 30-40 years make it possible to fabricate nanometer-sized systems where fluctuations and quantum effects are important features. These systems can be controlled and measured with high accuracy, making them suitable for exploring fundamental aspects of the microscopic world. This thesis makes contributions in this direction, focusing on the th
We have calculated the band structures for strained segmented nanowires involving all combinations of AlN, GaN, InN, AlP, GaP, AlAs, GaAs, InP, InAs, AlSb, GaSb, and InSb, as a function of segment length. This was done for two different growth directions of the wires, [100] and [111]. Both the Gamma and the X conduction-band minima were included in the calculations as well as the valence bands. Sh

A method to compute spin-orbit coupling between electronic states is presented. An effective one-electron spin-orbit Hamiltonian is used, based on atomic mean field integrals, The basic electronic states are obtained using the restricted active space (RAS) SCF method. The Hamiltonian matrix is obtained by an extension of the restricted active space state interaction (RASSI) method. Several hundred
NanoLund Mentoring programme The NanoLund Mentoring programme aims to support our PhD-students in navigating their carrier choices. In the Mentoring programme, students get an opportunity to discuss their professional ambitions and challenges with an independent mentor from outside our organisation, and often outside academia. The programme is intended to provide guidance tailored to the student's

Attitudes of Gen Z and their role in the workplace have been widely studied in the past decades. Even though Gen Z and Millennials have some similar workplace attitudes, the rapid change in technology experienced by Gen Z has inculcated some very unique working attitudes in the new generation, which in turn has impacted their expectations of middle management and their preference for such role
α-Synuclein is a synaptic protein that accumulates primarily in synucleinopathies and secondarily in certain lysosomal storage disorders. However, its physiological roles in health and disease are not fully understood. In part, this has been hampered by the inability to visualize α-synuclein and its cellular localization, due to the lack of specific antibodies and faithful reporters. Here, we used
This work describes the intricacies of the determination of the trimethylselenonium ion (TMSe) in human urine via high-performance liquid chromatography–hydride generation–atomic fluorescence spectrometry (HPLC-HG-AFS). By definition, this technique requires that the separated TMSe can be online converted into a volatile compound. Literature data for the determination of TMSe via the hydride gener
Popular Abstract in Swedish Immunförsvaret har till uppgift att skydda kroppen mot främmande mikroorganismer såsom bakterier och virus. En rad olika celler, vävnader samt organ samarbetar för att utforma ett väl fungerande immunförsvar. Det är ytterst viktigt att immunförsvaret känner igen kroppsfrämmande ämnen (antigen), som till exempel bakterieceller, men också att det skiljer dessa från kroppsGeneration of long-lived plasma cells and memory B cells of high affinity takes place in germinal centers and depends on help from a specialized CD4+ T cell subset termed T follicular helper (Tfh) cells. These processes are crucial for long-term protection upon natural infection or in settings of vaccination, however they are also responsible for development of antibody-mediated autoimmune disease
Environmental enrichment (EE) alleviates sensorimotor deficits after brain infarcts but the cellular correlates are not well-known. This study aimed to test the effects of postischemic EE on neocortical cell genesis. A neocortical infarct was caused by distal ligation of the middle cerebral artery in adult spontaneously hypertensive rats, subsequently housed in standard environment or EE. Bromodeo
n the current study, we address the underlying mechanism for the selective generation of gut-homing T cells in the gut-associated lymphoid tissues (GALT). We demonstrate that DCs in the GALT are unique in their capacity to establish T cell gut tropism but in vivo only confer this property to T cells in the presence of DC maturational stimuli, including toll-like receptor-dependent and -independent
Coals with similar thermal maturity and from the same deposit normally show a considerable range in petroleum generation potential as measured by the Hydrogen Index (HI). This variation may partly be related to variations in plant input to the precursor mires and organic matter preservation. It is widely accepted that some Cenozoic coals and coaly sediments have the potential to generate oil, whic
The auto-ignition caused by oblique shocks was investigated experimentally in a supersonic flow regime, with the incoming flow at a Mach number of 2.5. The transient characteristics of the auto-ignition caused by shock evolvements were recorded with a schlieren photography system, and the initial flame kernel generation and subsequent propagation were recorded using a high-speed camera. The fuel m
Syftet med studien är att undersöka hur Generation Z upplever lojalitetsprogram inom dagligvaruhandeln, med särskilt fokus på hur programmens olika inslag bidrar till att skapa kundengagemang och i vilken utsträckning detta kan relateras till kundlojalitet. Studien syftar vidare till att bidra med en ökad förståelse för lojalitetsprogram ur ett konsumentperspektiv, då tidigare forskning främst fok
This thesis analyses how the growth of wind and solar PV generation has affected wholesale electricity prices in Spain between 2020 and 2025, and how that relationship evolved as renewable penetration increased. Using 52,603 hourly observations obtained from the REE ESIOS public data portal — covering OMIE day-ahead spot prices, electricity demand, wind generation, and solar PV generation — the st
This thesis describes the work done on two open access microcavities that aims at detecting single rare-earth ions for quantum information applications. The initial microcavity faced mechanical instability due to its geometry, which limited robust design possibilities due to the 25 mm diameter space of the helium bath cryostat. A Purcell enhancement of 2.2 was realized for nanoparticles at 2.1 K,
Cesium manganese chloride (CsMnCl3) nanocrystals (NCs) have recently been recognized as potential lead-free perovskite candidates for red emission. To ascertain how the luminescence properties depend on the NC structures formed under different synthesis conditions, we synthesized CsMnCl3NCs in two polymorphic structures, namely, cubic (c-CsMnCl3) and rhombohedral (r-CsMnCl3), by tuning the reactio
