CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially. Hereby, it becomes possible to follow the dynamics of Pd(100) restructuring between a

Background A better characterization of diabetic retinopathy (DR) may be helpful to monitor early disease, predict progression of DR, and to evaluate new treatment strategies. Visual function has been suggested to complement the assessment of microvascular lesions in DR but needs to be evaluated in longitudinal studies. Objectives This prospective longitudinal cohort study investigated whether ear

Organo-metal halide perovskites are promising solution-processed semiconductors, however, they possess diverse and largely not understood non-radiative mechanisms. Here, we resolve contributions of individual non-radiative recombination centers (quenchers) in nanocrystals of methylammonium lead iodide by studying their photoluminescence blinking caused by random switching of quenchers between acti

PURPOSE: This study aimed to investigate inequality and heterogeneity in health-related quality of life (HRQoL) and to provide EQ-5D-5L population reference data for Sweden.METHODS: Based on a large Swedish population-based survey, 25,867 respondents aged 30‒104 years, HRQoL is described by sex, age, education, income, economic activity, health-related behaviours, self-reported diseases and condit

Semiconductor materials (e.g., conjugated polymers, metal halide perovskites) have been widely used in solar cells, light-emitting diodes, and photodetectors. Organic conjugated systems have high mechanical flexibility and low costs for production. Metal halide perovskites have the advantage of strong light absorption, long charge-carrier diffusion lengths, and low intrinsic surface recombination.

The high efficiency of the special pair in initiating electron transfer in reaction centers is not well understood. By using 2DES, we identified the charge transfer state, which is responsible for the charge separation function.

Optical nonlinear spectroscopies carry a high amount of information about the systems under investigation; however, as they report polarization signals, the resulting spectra are often congested and difficult to interpret. To recover the landscape of energy states and physical processes such as energy and electron transfer, a clear interpretation of the nonlinear signals is prerequisite. Here, we

Metal halide perovskites are an important class of emerging semiconductors. Their charge carrier dynamics is poorly understood due to limited knowledge of defect physics and charge carrier recombination mechanisms. Nevertheless, classical ABC and Shockley-Read-Hall (SRH) models are ubiquitously applied to perovskites without considering their validity. Herein, an advanced technique mapping photolu

As a classical polymer acceptor material, N2200 has received extensive attention and research in the field of polymer solar cells (PSCs). However, the intrinsic properties of ground- and excited-states in N2200, which are critical for the application of N2200 in PSCs, remain poorly understood. In this work, the ground- and excited-state properties of N2200 solution and film were studied by steady-

When measuring inequality using conventional inequality measures, ethical assumptions about distributional preferences are often implicitly made. In this paper, we ask whether the ethical assumptions underlying the concentration index for income-related health inequality and the Gini index for income inequality are supported in a representative sample of the Swedish population using an internet-ba

Background and purpose —The use of a tourniquet in knee replacement surgery is debated. Given the conflicting evidence, we aimed to compare the risk of revision after total knee replacements (TKR) with or without the use of tourniquet. Methods — In this register based observational study, we included the 5 most common cemented primary TKR models due to osteoarthritis reported to the Swedish Arthro

Aim: To evaluate the impact of initial mono- versus multitherapy on the ocular surface and related quality of life after 5 years follow-up in the Glaucoma Intensive Treatment Study (GITS). Method: The study included patients with primary open-angle glaucoma and pseudoexfoliation glaucoma who completed 5-year follow-up in GITS. Assessment of ocular surface disease (OSD) symptoms was done using a Sw

Objective: The aim of this study was to investigate the experiences of school nurses working with refugee children from Ukraine. Design: This research was conducted as a qualitative interview study, using an inductive approach and a semi-structured interview guide. Sample: School nurses (n = 8) from different parts of Sweden were interviewed, and the data were analyzed through a qualitative conten

Charge generation, injection and recombination in quantum dot-sensitized ZnO nanowires was probed using time resolved terahertz spectroscopy. The mobility spectrum at different representative pump-probe delays showed similar behavior during the injection time indicating free charges on the nanowire structures.

Using terahertz and transient absorption spectroscopy, carrier dynamics in organo halide perovskite solar cell is probed. Charge generation is <100 fs, followed by 2 ps charge formation with balanced electron hole mobility of 20 cm2V-1s-1.

Ulnar nerve entrapment at the elbow (UNE) is the second most common compression neuropathy in the upper limb. Immediate return-to-work (RTW) after surgery is seldom possible due to restrictions and recovery demands. We aimed to explore RTW after UNE surgery and investigate factors contributing to variations. A prospective study with patients undergoing primary UNE surgery was conducted. Treatment

Background: Large bone defects are challenging to manage clinically and usually require treatment with bone graft or bone graft substitute. This study evaluated the effect of romosozumab, a sclerostin antibody, in combination with demineralized bone matrix (DBM) on bone regeneration in a critical-size ulnar defect model in nonhuman primates. Methods: In cynomolgus monkeys (N = 22, male, 10–12 year

Asthma is a common, multifaceted respiratory disease with a major impact on quality of life. Despite increased insights into mechanisms underlying various asthma phenotypes and endotypes and the availability of targeted biologic treatment options, the disease remains uncontrolled in a substantial proportion of patients with risk of exacerbations, requiring systemic corticosteroids, and with progre

Upper-limb complications (ULCs) in diabetes, affecting joints, tendons, muscles, con-nective tissue, nerves, and skin, are underrecognized but prevalent conditions in type 1 and type 2 diabetes. Advances in diabetes care have extended life expectancy, leading to an aging population with diabetes with increased susceptibility to long-term complications beyond traditional vascular issues. Despite so
