Aim: The aim of the study was to illustrate the potential health benefits of cleaner air in Sweden by conducting a comprehensive health impact assessment, using a population sample of 100,000 individuals

Thermoelectric cooling of a finite reservoir coupled to a quantum dot

We investigate nonequilibrium transport of charge and heat through an interacting quantum dot coupled to a finite electron reservoir. Both the quantum dot and the finite reservoir are coupled to conventional electric contacts, i.e., infinite electron reservoirs, between which a bias voltage can be applied. We develop a phenomenological description of the system, combining a rate equation for trans

Grain size control in quasi-two-dimensional perovskite thin film via intermediate phase engineering for efficient bound exciton generation

Quasi-two dimensional (2D) perovskites have emerged as a promising class of materials due to their remarkable photoluminescence efficiency, which stems from their exceptionally high exciton binding energies. The spatial confinement of excitons within smaller grain sizes could enhance the formation of biexcitons leading to higher radiative recombination efficiency. However, the synthesis of high-qu

Effective uniaxial dielectric function tensor and optical phonons in (2 ¯ 01)-oriented β - Ga2 O3 films with equally distributed sixfold-rotation domains

Monoclinic β-Ga2O3 films grown on c-plane sapphire have been shown to exhibit six (2¯01)-oriented domains, which are equally spaced by rotation around the surface normal and equally sized by volume that render the film optical response effectively uniaxial. We derive and discuss an optical model suitable for ellipsometry data analysis of such films. We model mid- and far-infrared ellipsometry data

Continuous Microwave Photon Counting by Semiconductor-Superconductor Hybrids

We present a continuous microwave photon counter based on superconducting cavity-coupled semiconductor quantum dots. The device utilizes photon-assisted tunneling in a double quantum dot with tunneling events being probed by a third dot. Our device detects both single and multiple-photon absorption events independently, thanks to the energy tunability of a two-level double-dot absorber. We show th

Detection of Very Fast Interface Traps at 4H-SiC/AlN and 4H-SiC/Al2O3 Interfaces

Modest channel carrier mobility in SiC-MOSFETs with NO annealed gate oxides has been the main factor hampering development of low power devices (300 – 650 V). A very fast interface trap, noted as NI, has been suggested to be the main culprit for poor inversion channel carrier mobility. The origin of the NI trap is unknown, but it is likely a property of the SiO2 and it is enhanced during post nitr

Facile In Situ Formation of Potassium Sodium Niobate (KNN) Using The Hexaniobate Polyoxometalate

Lead-based piezoceramics are the dominant materials used in electronic devices, despite the known toxicity of lead. Developing safer piezoelectric materials has inspired the pursuit of lead-free piezoceramics, however some challenges remain in accessing these materials reproducibly. Here we demonstrate a simple and robust method for synthesis of the lead-free piezoceramic material, potassium sodiu

COVID-19 in Individuals with Severe Alpha 1-Antitrypsin Deficiency

Background:cThe risk of coronavirus (COVID-19) can be affected by the presence of certain chronic conditions. It is unknown if individuals with severe hereditary alpha-1-antitrypsin deficiency (AATD) faced an increased risk of severe COVID-19 infection during the pandemic and if COPD in this population affected the risk of severe COVID-19 outcomes. Aim: Our aim was to investigate COVID-19 outcomes

Ultrafast Two-Dimensional Spectroscopy of Photosynthetic Systems

This chapter starts with a review of the theoretical foundation for understanding two-dimensional electronic spectroscopy (2DES) signals in molecular systems. We derive and motivate key properties of 2DES, demonstrating its ability to yield complex information about energy transfer processes and couplings within molecular assemblies, such as photosynthetic antennae. We continue with a discussion e

Surgery Combined with Local Implantation of Doxorubicin-Functionalized Hydroxyapatite Halts Tumor Growth and Prevents Bone Destruction in an Aggressive Osteosarcoma

Osteosarcoma treatment comprises pre-surgical chemotherapy followed by radical surgery and further chemotherapy cycles, but the prognosis has been far from satisfactory. No new drugs or treatment modalities have been developed for clinical use in the last four decades. We describe a nano-hydroxyapatite (HA)-based local drug delivery platform for the delivery of doxorubicin (DOX), a cornerstone dru

(G)Patching up mis-splicing in cancer

Benbarche, Pineda, Galvis, et al. delineate an essential role for the G-patch motif-containing protein GPATCH8 in mis-splicing associated with cancer-driving mutations of the splicing factor SF3B1. GPATCH8 cooperates with SF3B1 mutants, affecting the splicing machinery. Targeting GPATCH8 reveals therapeutic opportunities for SF3B1 mutant cancers and other splicing-related diseases.

Hemilabile Thio– and Selenoethers in Bis(benzimidazolyl)Amine Copper Complexes Relevant to the Active Sites of Copper-Dependent Monooxygenases

Copper complexes supported by benzimidazole-based tetradentate neutral ligands featuring thio- and selenoether donors, resemble the coordination environment of the active site in copper dependent monooxygenases Dopamine-β-monooxygenase (DβM) and peptidylglycine-α-hydroxylating monooxygenase (PHM). The cuprous complexes react with O2 at low temperature generating a reactive copper-oxygen species as

On ultrafast x-ray scattering methods for magnetism

With the introduction of x-ray free electron laser sources around the world, new scientific approaches for visualizing matter at fundamental length and time-scales have become possible. As it relates to magnetism and ‘magnetic-type’ systems, advanced scattering methods are being developed for studying ultrafast magnetic responses on the time-scales at which they occur. We describe three capabiliti

Novel methods to study amyloid oligomers

Amyloid protein deposits are the hallmark of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, or diabetes type II. Although their connection to the diseases is not fully understood, many studies point at intermediate species called oligomers as being the main responsible for the toxicity of these proteins. This makes them strong candidates as therapeutic targets. However, due to their
