Anion exchange membranes (AEMs) play a vital role in AEM water electrolysis (AEMWE), a promising technology for hydrogen production. However, it remains challenging to develop AEMs that simultaneously achieve high OH− conductivity, robust alkaline stability, and sustained operational performance in AEMWE. In the present study, we report on a class of high-performance, readily synthesized AEMs base
The formation of the intermetallic 𝜎 phase (space group 𝑃42/𝑚𝑛𝑚) has a detrimental effect on the ductility of transition-metal alloys. This theoretical study uses first-principles calculations to investigate the stability and thermodynamic properties of the WRe and WOs 𝜎 phases. Our study indicates that the 𝜎 phase becomes thermodynamically stable at its ideal composition for temperature
China is an extraordinary country; in the last 30 years the economic development has moved forward in an almost impossibly high and even speed. The GDP has grown with an annual average of ten percent and placed the Chinese economy among the top three largest economies in the world. But while the economic development keep racing ahead, the democratic development has slowed down and is now standing
BACKGROUND: Depressive disorders are associated with immune system alterations that can be detected in the blood. Cytokine concentrations in cerebrospinal fluid (CSF) and their relationship to aspects of suicidality have previously not been investigated. METHODS: We measured interleukin-1beta, interleukin-6 (IL-6), interleukin-8, and tumor necrosis factor-alpha (TNF-alpha) in CSF and plasma of sui
Our existing urban environment has a significant potential to increase the use of renewable energy, mainly by using solar irradiation for heat and electricity. Quantification of the solar potential by means of a solar map is the first step in the acceleration process for using more solar energy in our urban environments. A solar map is a GIS system providing the annual solar irradiation on buildin
Economic historians tend to explain US geographical development gaps in terms of industrialisation. But by the end of the 20th century, the richest counties had become specialised in services, rather than in manufacturing. This column evaluates how the service economy triggered this evident contrast between the urban and rural US. Market size causes localisation of non-agricultural activity, with
The exploitation of migrant workers is widespread in the Nordic countries in labour intensive sectors. This article investigates whether there is any criminal law protection in practice for exploited migrant workers in Sweden. On the basis of descriptive statistics regarding the outcomes of criminal investigations on human trafficking for forced labour and on human exploitation for forced labour a
During forebrain development, Mash1 directs gamma-aminobutyric acid (GABA)ergic neuron differentiation ventrally in the ganglionic eminences. Repression of Mash1 in the cortex is necessary to prevent the formation of GABAergic interneurons. Negative regulation of Mash1 has been attributed to members of the Neurogenin family; the genetic ablation of Neurogenin2 (Ngn2) leads to the derepression of M
The transcriptional enhancer region in intron 1 of the proto-oncogene MDM2 contains a polymorphic site (SNP309) that may harbor a G or a T nucleotide. Previous studies have shown that the G allele confers a higher affinity for the Sp1 transcription factor, resulting in an increased transcriptional activity of MDM2. A constitutional G allele has also been associated with earlier onset of various ca
Granulocyte chemotactic protein 2 (GCP-2)/CXCL6 is a CXC chemokine expressed by macrophages and epithelial and mesenchymal cells during inflammation. Through binding and activation of its receptors (CXCR1 and CXCR2), it exerts neutrophil-activating and angiogenic activities. Here we show that GCP-2/CXCL6 itself is antibacterial. Antibacterial activity against gram-positive and gram-negative pathog
Inspired by cultural geographer David Crouch’s description of heritage as a journey,3 this paper looks at how the narrator’s physical and mental voyage towards the old capital of her childhood incorporates multiple spatiotemporal layers of urban cultural heritage in order to reach a deeper understanding of the living historical city she calls home.
Facilitated by mobility, occupational participation outside the home is vital in old age. However, the relative importance of factors influencing mobility and occupational participation remains unclear. The present study describes older peoples’ motives for, and experiences of, mobility and occupational participation outside the home. Nine focus-group interviews were conducted and analyzed using c
To investigate a putative involvement of protein kinase C (PKC) isoforms in supporting neuroblastoma cell proliferation, SK-N-BE(2) neuroblastoma cells were transfected with expression vectors coding for the C2 and V5 regions from different PKC isoforms. These structures have been suggested to inhibit the activity of their corresponding PKC isoform. The PKC fragments were fused to enhanced green f
