In this work, growth of InN quantum dots (QDs) on GaN nanowires (NWs) by metal-organic vapour phase epitaxy is demonstrated, illustrating the feasibility to combine 0D and 1D structures for nitride semiconductors. Selective area growth was used to generate arrays of c-oriented GaN NWs using Si3N4 as the mask material. In general, InN QDs tend to form at the NW edges between the m-plane side facets
Surface affinity, orientation and ion pairing are investigated in mixed and single solute systems of aqueous sodium hexanoate and hexylammonium chloride. The surface sensitive X-ray photoelectron spectroscopy technique has been used to acquire the experimental results, while the computational data have been calculated using molecular dynamics simulations. By comparing the single solute solutions w
The atomic contributions to valence electronic structure for 37 ionic liquids (ILs) are identified using a combination of variable photon energy XPS, resonant Auger electron spectroscopy (RAES) and a subtraction method. The ILs studied include a diverse range of cationic and anionic structural moieties. We introduce a new parameter for ILs, the energy difference between the energies of the cationi
Assemblies of anisotropic particles commonly appear in studies of active many-body systems. However, in two dimensions, the geometric ramifications of the finite density of such objects are not entirely understood. To fully characterize these effects, we perform an in-depth study of random assemblies generated by a slow compression of frictionless elliptical particles. The obtained configurations
We report the first systematic investigation of relativistic effects on the UV-vis spectra of two prototype complexes for so-called photo-activated chemotherapy (PACT), trans-trans-trans-[Pt(N3)2(OH)2(NH3)2] and cis-trans-cis-[Pt(N3)2(OH)2(NH3)2]. In PACT, design of new drugs requires in-depth understanding of the photo-activation mechanisms. A first step is usually to rationalize their UV-vis spe
On a planetary scale, the D/H ratio on Mars is a key diagnostic for understanding the past history of water on the planet; locally, it can help to constrain the sources and sinks of water vapor through the monitoring of condensation and sublimation processes. To obtain simultaneous measurements of H2O and HDO lines, we have used the Echelle Cross Echelle Spectrograph (EXES) instrument aboard the S
Huvuddelen av all miljöpåverkan kan kopplas till vår konsumtion. I takt med att reallönerna ökar så ökar också konsumtionen – fler semesterresor, fler klädinköp, snabbare utbyte av produkter mot nyare versioner och så vidare. Denna utveckling utgör ett hot mot planetens tillstånd. I arbetetmed FN:s hållbarhetsmål ligger de nordiska länderna högt i den allmänna rankingen, men när det gäller delmål
Multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and relativistic configuration interaction (RCI) calculations are performed for states of the 3s23p2, 3s3p3 and 3s23p3d configurations in the Si-like ions Ti IX - Ge XIX, Sr XXV, Zr XXVII and Mo XXIX. Valence and core-valence electron correlation effects are accounted for through large configuration state function expansions. Calculated en
The cartilage aggrecan proteoglycan is crucial for both skeletal growth and articular cartilage function. A number of aggrecan (ACAN) gene variants have been linked to skeletal disorders, ranging from short stature to severe chondrodyplasias. Osteochondritis dissecans is a disorder where articular cartilage and subchondral bone fragments come loose from the articular surface. We previously reporte
Den tredje februari 2022 anordnades en workshop vars syfte var att diskutera policy rekommendationer som skulle kunna främja utvecklingen av energigemenskaper i Sverige. Under workshopen diskuterades energigemenskapers möjlighet att äga nät, incitamentsstruktur för att utveckla energigemenskaper och huruvida energiföretag bör tillåtas vara medlemmar i energigemenskaper. Deltagarna i workshopen var
BACKGROUND: Asthma is the most frequent chronic disease in children. One of the most replicated genetic findings in childhood asthma is the ORMDL3 gene confirmed in several GWA studies in several paediatric populations.OBJECTIVES: The purpose of this study was to analyse ORMDL3 variants and expression in childhood asthma in the Polish population.MATERIALS AND METHODS: In the study we included 416
This article explores the discourses, actors, and cross-border exchanges thatshape the broader landscape of contemporary transnational feminist andqueer non-governmental organizations (NGOs). While several studies havepointed to the co-opted role of NGOs, fewer have explored the potential forNGOs to influence the conditions under which they operate. That is what thisarticle sets out to do, with th
Wanting to help others and benefit society in one’s future career are examples of communal career goals. Raising these goals in youth should increase interest in HEED-occupations (Healthcare, Early Education, Domestic, and the Domestic fields) which are strongly gender-skewed and face labor shortage. Research has yet to find ways to increase communal career goals. In this study, we test the novel Wanting to help others and benefit society in one’s future career are examples of communal career goals.

Development of islet autoimmunity precedes the onset of type 1 diabetes in children, however, the presence of autoantibodies does not necessarily lead to manifest disease and the onset of clinical symptoms is hard to predict. Here we show, by longitudinal sampling of islet autoantibodies (IAb) to insulin, glutamic acid decarboxylase and islet antigen-2 that disease progression follows distinct tra
“The definition of insanity is doing the same thing over and over again but expecting different results.” This quote by Albert Einstein highlights our need for new formats of communication to address the knowledge-action gap regarding climate change and other sustainability challenges. This includes reflection, and communication spaces, as well as methods and approaches that can catalyze the emerg
