Evaluation of intermittent contact mode AFM probes by HREM and using atomically sharp CeO2 ridges as tip characterizer

The imaging process of the atomic force microscope (AFM) in contact, noncontact, and intermittent contact mode is still debated after more than a decade of widespread use, in particular when imaged features are approaching atomic dimensions. Several models for the interaction between the tip and the surface have been suggested, but, generally they all need an exact description of the geometry of e

Is an elevated family-genetic risk for major psychiatric disorders specific to creative occupations?

Background Despite a large descriptive literature linking creativity and risk for psychiatric illness, the magnitude and specificity of this relationship remain controversial. Methods We examined, in 1 137 354 native Swedes with one of 59 3-digit official and objective occupational codes in managerial and educated classes, their familial genetic risk score (FGRS) for ten major disorders, calculate

Sharp microfaceting of (001)-oriented cerium dioxide thin films and the effect of annealing on surface morphology

Cerium dioxide, CeO2, is a chemically stable oxygen-ion-conducting material, which has been extensively used as an additive or support in oxidation catalysts. The fact that catalytic behaviour is often surface structure sensitive and/or edge atom dependent suggests that different surfaces might be discernible in associated redox processes. Thus, it is desirable to realise CeO2 films with a well-de

Strain state in semiconductor quantum dots on surfaces : a comparison of electron microscopy and finite element calculations

The strain distribution in InP quantum dots, coherently grown on a GaInP substrate, was determined by image analysis of high-resolution electron microscopy images. Image simulations were used to verify the obtained results. The measured strain values were compared with values obtained from finite element calculations, using the dot shape determined by electron microscopy. The measured and calculat

High-Efficiency Photoinduced Charge Separation in Fe(III)carbene Thin Films

Symmetry-breaking charge separation in molecular materials has attracted increasing attention for optoelectronics based on single-material active layers. To this end, Fe(III) complexes with particularly electron-donating N-heterocyclic carbene ligands offer interesting properties with a 2LMCT excited state capable of oxidizing or reducing the complex in its ground state. In this Communication, we

Compositional information from amorphous Si-Ge multilayers using high-resolution electron microscopy imaging and direct digital recording

A simple method for extracting compositional information from high-resolution electron microscopy images of an amorphous two-element system using a slow-scan CCD camera has been developed. The method has been evaluated on amorphous Si/Ge multilayers. The characterisation of the multilayers provided information about thickness of the layers, maximum concentrations within the layers and elemental pr

Accountabilities, invisibilities and silences in a Danish slave trading company on the Gold Coast in the early 18th century

Using eighteenth-century archival material from a Danish trading fort in West Africa, we explore how accounting and accountability systems were complicit with the crafting and narration of racialized slave trading during mercantile colonialism. By examining the role of accounting not at the slave trade's endpoint, e.g., plantations in the Americas, but at its points of extraction, we reveal the ro

Vad sjutton ska jag lyssna på nu? : En kvalitativ intervjustudie om ljudboksanvändares val av ljudböcker

När bokbranschen nu genomgår en förändring där digitala böcker blir allt mer populära är det viktigt för förlagen att veta hur användarbeteendet ser ut när det gäller de nya plattformarna. Hur går det egentligen till när ljudboksanvändare väljer ljudböcker? Den frågan ger den här undersökningen svar på genom att undersöka vilka faktorer som påverkar valet av ljudbok. Faktorerna utbud, omslag, förf

Kvalitetslitterära debuter : En fallstudie om hur prisvinnande debutanter värderas på bokmarknaden

The aim of this analysis has been to investigate how the books Osebol (2019), Samlade verk (2020) and Eufori (2021) have been received and treated on the Swedish book market, while focusing on how these books are being associated with high-quality literature while at the same time being debut books. A case study has been carried out in four different time periods of these books’ lifespan, from adm

Litteratur utan själ : En litteratursociologisk studie om diskussionen kring samt användningen av AI i förlagsbransche

Syftet med uppsatsen är att undersöka hur tolv svenska skönlitterära förlag tänker kring att använda AI (artificiell intelligens) inom sin verksamhet, vilka hinder som kan finnas, samt om åsikterna kring AI är kopplade till synen på litterärt värde. Frågeställningarna som undersökningen utgår från fokuserar på hur förlagsanställda ställer sig till den potentiella användningen av AI i förlagsarbete

Metastasis and recurrence patterns in the molecular subtypes of urothelial bladder cancer

Urothelial cancer of the urinary bladder frequently metastasizes to lymph-nodes, lungs, liver and bone. A taxonomy for molecular classification exists, but it is unknown if molecular subtypes show tropism for different organs. Here, we study 146 patients with de novo metastatic disease or recurrence after curative treatment. We classify primary tumors using two transcriptomic methods and immunosta

Niobium-doped strontium titanates as SOFC anodes

Sr-vacancy compensated Nb-doped SrTiO3 with the nominal composition Sr0.94Ti09Nb0.1O3 has been evaluated as part of a solid oxide fuel cell (SOFC) anode material in terms of redox stability, electrical conductivity, as well as electrochemical properties. Sr0.94Ti0.9Nb0.1O3 has been synthesized with a recently developed modified glycine-nitrate process. The synthesized powders have been calcined an

What is photosynthesis?-A broader and inclusive view

In general, the word, photosynthesis, is considered synonymous with oxygenic photosynthesis, a process by which cyanobacteria, algae, aquatic, and terrestrial plants produce oxygen and carbohydrates, using light (photons), water and carbon dioxide. Further, we have anoxygenic bacterial photosynthesis where oxygen is not evolved, but a substrate, other than water, is oxidized, and rhodopsin-type sy

Identifying actionable druggable targets for breast cancer : Mendelian randomization and population-based analyses

Background: Drug repurposing provides a cost-effective approach to address the need for breast cancer prevention and therapeutics. We aimed to identify actionable druggable targets using Mendelian randomization (MR) and then validate the candidate drugs using population-based analyses. Methods: We identified genetic instruments for 1406 actionable targets of approved non-oncological drugs based on

Résumé Français: Si l’écriture inclusive polarise largement l’opinion publique, les causes exactes des réticences envers son usage ne sont pas toujours très claires. Nous explorons les liens entre les attitudes envers l’écriture inclusive et différents facteurs, comme le niveau de connaissance linguistique ou historique de l’écriture inclusive. Nous avons également mesuré l’orientation politique dAlthough gender inclusive writing is widely polarised in public opinion, the exact causes of reluctance towards its use are not always clear. We explore the link between attitudes towards inclusive writing and different factors, such as the level of linguistic or historical knowledge of inclusive writing. We also measured the political orientation of the respondents, as well as their views on the

Transforming growth factor-β2 is associated with atherosclerotic plaque stability and lower risk for cardiovascular events

Aims: Transforming growth factor-beta (TGF-β) exists in three isoforms TGF-β1, -β2, and -β3. TGF-β1 has been suggested to be important for maintaining plaque stability, yet the role of TGF-β2 and -β3 in atherosclerosis remains to be investigated. This study explores the association of the three isoforms of TGF-β with plaque stability in the human atherosclerotic disease. Methods and results: TGF-β
