BackgroundMale involvement in maternal health care has proven to be beneficial for improving maternal and child health and is often crucial in areas of family planning and contraceptive use. However, compared to male involvement in maternal health care, male involvement in contraceptive counselling is complex and controversial and thus faces certain challenges. Immigrant men in Sweden are often ac

Al-alloys incorporating Mn, Cr and Zr, tailored for powder bed fusion-laser beam processes with solubilities three times equilibrium have recently been developed that yield a high strength. Mn and Cr-enriched precipitates that form during printing and heat treatment influence the material’s mechanical properties hence making it important to understand their kinetics. In this study, direct imaging

North - South collaboration between scientists and collaborators is increasingly prominent and promoted in research. This study examines power dynamics within a North-South research collaboration project conducted between institutions in Tanzania and Germany. The research design is guided by postcolonial considerations of knowledge production and seeks to amplify underrepresented voices from the S

Deep eutectic solvents (DESs) are an emerging class of modern, often “green” solvents with unique properties. Recently, a deep eutectic system based on amphiphilic surfactant N-alkyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (C12 & C14 sulfobetaine) and (1S)-(+)-10-camphor-sulfonic acid in the molar ratio 1:1.5 has been reported. Nanostructuring can be expected in this DES due to the nature of

Self-replication of amyloid fibrils via secondary nucleation is an intriguing physicochemical phenomenon in which existing fibrils catalyze the formation of their own copies. The molecular events behind this fibril surface-mediated process remain largely inaccessible to current structural and imaging techniques. Using statistical mechanics, computer modeling, and chemical kinetics, we show that th

The solid-liquid interface, where corrosion reactions occur, is notoriously difficult to study in operando conditions. Few experimental techniques can provide surface sensitivity and spatial and temporal resolution and are compatible with liquid environments. 2-Dimensional surface optical reflectance (2D-SOR) is an emerging optical technique providing microscopic information with high temporal res

Direct thermal-to-electric energy converters typically operate in the linear regime, where the ratio of actual maximum power relative to the ideal maximum power, the so-called fill factor (FF), is 0.25. Here, we show, based on fundamental symmetry considerations, that the leading order nonlinear terms that can increase the FF require devices with broken spatial symmetry. Studying nonlinear, thermo

BACKGROUND: Perfluoroalkyl substances (PFAS) have been associated with impaired antibody levels after childhood vaccinations and immunosuppressive effects in animals. However, the in vivo effects of PFAS on antigen specific human T cell responses have not been investigated in adults. In Ronneby, Sweden, the drinking water of one of the water works was previously highly contaminated with primarily

Extracellular plaques in Alzheimer’s disease contain Aβ peptides and ganglioside lipids such as GM1. Aβ monomers self-assemble into beta-sheet-rich fibrils when their concentration exceeds solubility, while GM1 monomers form spherical micelles above their critical concentration. This study examines the self-assembly of Aβ in the first two papers and its co-assembly with GM1 in the last two. In Pap

The strategy of pre-training a large model on a diverse dataset, then fine-tuning for a particular application has yielded impressive results in computer vision, natural language processing, and robotic control. This strategy has vast potential in adaptive control, where it is necessary to rapidly adapt to changing conditions with limited data. Toward concretely understanding the benefit of pre-tr

The band offsets of semiconductor heterojunctions are critical parameters for the design of electronic and optoelectronic devices. In this work, we report the fabrication of a Co3O4/3C-SiC p-n heterojunction and the determination of the conduction band and valence band offsets at the Co3O4/3C-SiC heterojunction. Our results reveal that the Co3O4/3C-SiC p-n heterojunction exhibits a type-II band al
