Fate of Optical Excitons in FAPbI3 Nanocube Superlattices

Understanding the nature of the photoexcitation and ultrafast charge dynamics pathways in organic halide perovskite nanocubes and their aggregation into superlattices is key for potential applications as tunable light emitters, photon-harvesting materials, and light-amplification systems. In this work, we apply two-dimensional coherent electronic spectroscopy (2DES) to track in real time the forma

Long-Term Pattern of Psychotropic Medication Uses Among Swedish Parents of Children Diagnosed With Cancer

BACKGROUND: Parents experience a range of mental health disorders following their child's cancer diagnosis. It is thus essential to explore how the child's cancer diagnosis affects the dosage of psychotropic medication in both short- and long-term use, as well as potential disparities in utilization patterns between mothers and fathers.PATIENTS AND METHODS: Using Swedish registers, we identified a

Signal amplification in molecular sensing by imprinted polymers

In the field of sensing, the development of sensors with high sensitivity, accuracy, selectivity, sustainability, simplicity, and low cost remains a key focus. Over the past decades, optical and electrochemical sensors based on molecular imprinting techniques have garnered significant attention due to the above advantages. Molecular imprinting technology utilizes molecularly imprinted polymers (MI

Imprecision plateaus in quantum steering

We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when introducing up to a threshold magnitude of measurement imprecision. This phenomenon, which we call an imprecision plateau, thus permits a departure from the standard assumption of idealized measurements without incurring a

Semidefinite Relaxations for High-Dimensional Entanglement in the Steering Scenario

We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method for detecting the entanglement dimensionality through certification of the Schmidt number. Its key feature is that the computational cost is independent of the Schmidt number under consideration. Secondly, we provide a m

Wear behaviour of PVD (Ti,Si)N-(Ti,Al)N coated cemented carbide in down milling pearlitic compacted graphite iron

Compacted graphite iron (CGI) is an intermediate material between conventional grey cast iron and the stronger, more wear resistant ductile iron, making it a suitable material choice for different automotive applications. The improved material properties of CGI as to conventional grey cast iron makes it more difficult to machine, and finding a suitable tool material with low wear rates is a challe

Self-Assembly of Quantum-Confined CsPbBr3 Perovskite Nanocrystals into Rhombic, Frame, and Rectangular Superlattices

Superlattices of quantum-confined perovskite nanocrystals (5–6 nm) present an interesting example of colloidal crystals because of the interplay between nanoscopic parameters (nanocrystal sizes, shapes, and colloidal softness) and the microscopic shapes of their assemblies. These superlattices are reported as rectangular or rhombic, with little discussion of the outcomes of self-assembly experimen

Photophysics and photochemistry of a d5 Ruthenium complex

Transition metal complexes (TMCs) with charge transfer states play a crucial role in photophysical and photochemical processes, particularly in energy conversion applications. This thesis investigates the photophysics and photochemistry of the d⁵ ruthenium complex ([Ru(III)(phtmeimb)2]+), focusing on its excited-state dynamics and charge transfer properties. The photophysical study involves steady

ENHANCING DIGITAL TWINS WITH DEEP REINFORCEMENT LEARNING : A USE CASE IN MAINTENANCE PRIORITIZATION

This paper introduces an innovative framework that enhances digital twins with deep reinforcement learning (DRL) to support maintenance in manufacturing systems. Utilizing a sophisticated artificial intelligence (AI) layer, this framework integrates real-time and historical production data from a physical manufacturing system to a digital twin, enabling dynamic simulation and analysis. Maintenance

Common infections in children aged 6 months to 7 years after high prenatal exposure to perfluoroalkyl substances from contaminated drinking water in Ronneby, Sweden

Background: Perfluorinated alkyl substances (PFAS) are suggested to impair immune function in children. Previous studies investigating associations between prenatal PFAS exposure and common infections were performed in background-exposed populations whilst studies from high-exposed populations are lacking. Objectives: To investigate the association between prenatal PFAS exposure from contaminated

Introduction: Persistent pharmaceutical contaminants, such as Platinum cytostatics, commonly used in cancer therapy, have been detected in water bodies at low concentrations. Electrochemical, photochemical and biological treatments for the removal and degradation of these contaminants are expensive and sometimes ineffective. Sorption methods are a viable and more efficient alternative. Objectives:

Exploring Structural Dynamics and Photophysics in Metal Halide Perovskites and Related Materials

Metal halide perovskites and related materials have sparked intense debate in the field of optoelectronic applications, including solar cells, light-emitting diodes, and lasers. Despite significant progress in improving device efficiency and stability, understanding the structure-property relationships remains largely elusive. This thesis presents an in-depth investigation of the structural dynami

Unraveling the Genetics of Shared Clinical and Serological Manifestations in Patients With Systemic Inflammatory Autoimmune Diseases

OBJECTIVE: Systemic inflammatory autoimmune diseases (SIADs) such as systemic lupus erythematosus (SLE), primary Sjögren disease (pSS), and idiopathic inflammatory myopathies (myositis) are complex conditions characterized by shared circulating autoantibodies and clinical manifestations, including skin rashes, among others. This study was aimed at elucidating the genetics underlying these common f

Programmable High-Dimensional Quantum Circuits in Space and Time

We harness the complex mixing process inside a commercial multi-mode fibre to program high-dimensional linear optical circuits for photonic qudits encoded in transverse space and time-of-arrival, and demonstrate their use for high-dimensional entanglement certification.

Boosting Membrane Interactions and Antimicrobial Effects of Photocatalytic Titanium Dioxide Nanoparticles by Peptide Coating

Photocatalytic nanoparticles offer antimicrobial effects under illumination due to the formation of reactive oxygen species (ROS), capable of degrading bacterial membranes. ROS may, however, also degrade human cell membranes and trigger toxicity. Since antimicrobial peptides (AMPs) may display excellent selectivity between human cells and bacteria, these may offer opportunities to effectively “tar

Cooling-Induced Order-Disorder Phase Transition in CsPbBr3 Nanocrystal Superlattices

Perovskite nanocrystal superlattices are being actively studied after reports have emerged on collective excitonic properties at cryogenic temperatures, where energetic disorder is minimized due to the frozen lattice vibrations. However, an important issue related to structural disorder of superlattices at low temperatures has received little attention to date. In this work, it is shown that CsPbB

History of cellular grafting for central nervous system repair—A clinical perspective

As late as in the 1970s, the evidence supporting that brain function might be restored by replacing dead cells by transplantation of new healthy cells was scarce in experimental animals and lacking in humans. Repairing the human brain was regarded as completely unrealistic by clinicians. Fifty years later, the situation is very different, and cellular grafting has reached patient application in se

Health impact assessment of exposure to road traffic noise and air pollution according to pre- and post-densification scenarios in Helsingborg, Sweden

A prevalent solution to accommodate population growth due to urbanization is densification. However, this often pushes new residential housing closer to roads, increasing exposure to both noise and air pollution. The present study's aim was to estimate the health impacts of road traffic-related noise and air pollution for a low-income area (Drottninghög) in Helsingborg, Sweden, according to pre-de
