We report on experimental determination of the strain and bandgap of InAsP in epitaxially grown InAsP-InP core-shell nanowires. The core-shell nanowires are grown via metal-organic vapor phase epitaxy. The as-grown nanowires are characterized by transmission electron microscopy, X-ray diffraction, micro-photoluminescence (μPL) spectroscopy, and micro-Raman (μ-Raman) spectroscopy measurements. We o
The anodic oxidation of metals such as aluminum and titanium can lead to the development of self-ordering pores. These pores make excellent templates for a range of nanoscale objects with many applications in nanoscience. Theoretical studies on pore formation have proposed several models for the establishment, growth, and ordering of these pores; however, experimental verification has mostly been
Self-ordered porous anodic alumina (PAA) films are studied extensively due to a large number of possible applications in nanotechnology and low cost of production. Whereas empirical relationships between growth conditions and produced oxides have been established, fundamental aspects regarding pore formation and self-organization are still under debate. We present in situ structural studies of PAA
Porous anodic alumina (PAA) can be used as a template for controlled electrodeposition and growth of nano-structures, it is also essential for long-lasting decorative coloring of aluminum. We have investigated the deposition of Sn nanopillars into PAA in-situ, with Grazing transmission small angle X-ray scattering, X-ray fluorescence and X-ray absorption near edge structure spectroscopy. An accumu
The growth of oxides and thin films is important in a wide range of applications, including coating technology, production of solar cell materials, and formation of dielectric layers in the semiconductor industry. These growth processes necessitate the interaction of a solid surface with a gas/vapor or liquid phase. The chemical processes that take place during the interaction of the solid with th
Biomass is becoming particularly important as a starting material for advanced carbon structures. In this study, we found interesting nanostructures on the surface of burnt spaghetti using scanning electron microscopy, transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDX) for analysis. The structures were elongated and finger-like, with evidence that the tubes have
Background: Diabetes during pregnancy is an increasingly common metabolic disorder, associated with significantly increased risks for both mother and child. Aim of this study was to compare maternal and perinatal outcomes in women with pregestational (PDM) type 1 (T1DM), type 2 diabetes (T2DM), gestational diabetes mellitus (GDM) and compare these to pregnancies not complicated with diabetes. This
A compact, high-repetition rate OPCPA system with CEP-stable 6.3 fs pulses duration and 10 μJ of pulse energy is presented together with results from numerical simulations. First results of high harmonic generation will be shown.
Background: Media frequently report on overall work-place challenges in Swedish schools, including teachers’ working conditions, their well-being, and students’ declining results. Language is the key to success in every school subject. Therefore, optimal language learning environments are important. Poor sound environments affect teachers’ vocal health, their general well-being, and students’ perf
The value of a quality-adjusted life-year (QALY) and the value of a statistical injury (VSI) are important measures within health economics and transport economics. Several studies have, therefore, estimated people's willingness to pay (WTP) for these estimates, but most results show scale insensitivity. The 'original' chained approach (CA) is a method developed to mitigate this problem by combini
Purpose: The postponement principle concerns defining when and where value is added, usually referring to hardware components for physical products. However, in modern supply chains, software’s importance is increasing, impacting the timing and location of value-adding operations. Lacking insights into software-driven implications for postponement, we aim at elaborating on the postponement princip
Tunnel Field-Effect Transistors (TFETs) offer more energy efficient alternative to CMOS for design of low power circuits. In spite of this potential, circuits based on TFETs have not been experimentally demonstrated so far. In this letter, we explore TFET fabrication and basic functionality of n-TFET based circuits in the following configurations: a current mirror, a diode-connected inverter, and
We used Raman spectroscopy to investigate phonon modes of single InP-InAs core-shell nanowire with a pure wurtzite phase to reveal the embedded strained state. Raman spectra show that the InP core exhibits tensile strain and the InAs shell exhibits compressive strain due to the radial heterostructure growth. Using different polarization excitation configurations, we identified distinct A1 (TO) and
Background: The study of emotion regulation (ER) has gained traction in forensic psychological and psychiatric research as a correlate of antisocial and aggressive behavior as well as for its relevance to psychopathology. However, conceptual and definitional ambiguity persists. Methods: This pre-registered systematic review aimed to investigate how ER is conceptualized and measured in forensic pop
Occupational exposure to cancer-causing agents is a major, yet preventable, contributor to cancer in Europe and globally. In the European Union (EU), cancer is responsible for nearly half of all work-related deaths, underscoring the critical need for prevention measures. Effective strategies typically involve regulatory and workplace measures aimed at reducing or eliminating exposure risks. Raisin
The European Code Against Cancer (ECAC) provides evidence-based recommendations to help individuals reduce their cancer risk. For the 5th edition (ECAC5), recommendations on ultraviolet radiation (UVR) and indoor radon exposures were updated, and complementary recommendations for policymakers were introduced. UVR and radon are classified as carcinogenic to humans (group 1 carcinogens) in the Inter
Most European Union (EU) residents live in areas where outdoor air pollution levels exceed the 2021 World Health Organization (WHO) air quality guidelines for fine particles and nitrogen dioxide. Outdoor air pollution is classified as carcinogenic to humans, and both outdoor and indoor air contain established human carcinogens, including diesel exhaust particulates, benzo(a)pyrene [B(A)P] and benz
