Air pollution affects human health and is particularly bad for susceptible groups, such as children. Health effects of air pollution are dependent on the particle deposition in the respiratory tract. To better understand the particle deposition for children we need to gain more knowledge about how and when the structure of the peripheral lung is developed.1

The polarization switching dynamics for Hf 1-x Zr x O 2 (HZO) integrated on InAs is studied as a function of pulse width and amplitude. Due to a mixed ferroelectric/antiferroelectric phase at x=0.8, a more gradual total polarization update is shown compared to a fully ferroelectric Hf 0.5 Zr 0.5 O 2 stack. A lowered operating voltage is achieved in Hf 0.2 Zr 0.8 O 2 by activating an inner ferroele

CsPbI3 nanocrystals (CPI NCs) have become a trending research topic due to their impressive potential in functional optoelectronic devices and optical gain applications. Their optical responses are governed by carrier dynamics, which is greatly influenced by temperature and corresponding phase structure due to the effects of inherently electron-phonon coupling. Notably, CPI NCs have been identifie

Here we describe an in vitro co-culture system that can differentiate hematopoietic progenitor populations to all major hematopoietic lineages at clonal level. We present both a sensitive single-cell switch-culture system as well as a less laborious alternative barcoding protocol more convenient for larger cell numbers. Importantly, generation of all lineages from single long-term hematopoietic st

An 8-band k · p theory is implemented for studying the electronic properties of near-surface lateral InxGa(1-x)As/InP heterostructure nanowires in the (100) direction. The change in bandgap and effective mass due to inhomogeneous strain are compared to unstrained scenario nanowires, and the lattice mismatch is varied from -3.2% to 1%. The nanowires' height is H = 5, 13 nm, and the width varies fro

Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied in situ. Herein we present a comparative XAFS study where the in situ sulfidation of Mo/δ-Al2O3 and Ni/δ-Al2O3 is compared to that of δ-Al2O3 supported NiMo catalysts with different NiMo ratios. The study also covers the com

RNA based processes are in the limelight due to the current technological advances from the fields of high throughput sequencing, structural probing and super-high resolution imaging. RNA biology is implicated in wide range of processes including embryonal development, maintenance of tissue homeostasis or tumor development and progression. We now gain insights at the unprecedented level on how RNA

Vertical graphene (VG) is a remarkable electrode material for supercapacitors due to its large specific area, open channel structures, and numerous exposed edges with high electrochemical activity. However, flexible supercapacitors with high rate performance based on VG have yet to be investigated. Here, we report flexible supercapacitors based on VG, carbon fabric (CF) current collector, and H2SO

BACKGROUND: Imaging ovarian cancer (OC) includes evaluating peritoneal carcinomatosis (PC) and enlarged cardio phrenic lymph nodes (CPLN) by computed tomography (CT), and thorough evaluation is tedious work. A "CT short score" with high-risk CT parameters might be a more pragmatic approach, but it is not known if such a short score associates with aggressive OC subtypes and impaired OC survival. F

The aim of this study was to establish traceable number concentration measurements of airborne particles beyond 10 μm in particle size. To this end, the primary standards for particle number concentration at the National Metrology Institutes of Switzerland and Japan were further developed to extend their measurement capabilities. Details on the upgraded setup are provided. An inter-comparison of t

To chemically modulate the ubiquitin-proteasome system for degradation of specific target proteins is currently emerging as an alternative therapeutic modality. Earlier we discovered such properties of the stem cell-supporting small molecule UM171 and identified that members of the CoREST complex (RCOR1 and LSD1) are targeted for degradation. UM171 supports the in vitro propagation of hematopoieti

BackgroundAmbulatory blood pressure (BP) monitoring has long been used to monitor BP in hypertension and lately emerged as a useful tool to detect hypotensive susceptibility in reflex syncope. However, hemodynamic characteristics in reflex syncope have not been sufficiently explored. The present study investigated the differences between ambulatory BP monitoring profiles associated with reflex syn

The photoluminescence (PL) of metal halide perovskites can recover after light or current-induced degradation. This self-healing ability is tested by acting mechanically on MAPbI3 polycrystalline microcrystals by an atomic force microscope tip (applying force, scratching, and cutting) while monitoring the PL. Although strain and crystal damage induce strong PL quenching, the initial balance betwee

Exposure to environmental factors is generally expected to cause degradation in perovskite films and solar cells. Herein, we show that films with certain defect profiles can display the opposite effect, healing upon exposure to oxygen under illumination. We tune the iodine content of methylammonium lead triiodide perovskite from understoichiometric to overstoichiometric and expose them to oxygen a

Objective: To identify subgroups of patients with magnetic resonance imaging (MRI)-confirmed degenerative meniscus tears who may benefit from arthroscopic partial meniscectomy (APM) in comparison with non-surgical or sham treatment. Methods: Individual participant data (IPD) from four RCTs were pooled (605 patients, mean age: 55 (SD: 7.5), 52.4% female) as to investigate the effectiveness of APM i
