Structural evolution of iron forming iron oxide in a deep eutectic-solvothermal reaction
Deep eutectic solvents (DES) and their hydrated mixtures are used for solvothermal routes towards greener functional nanomaterials. Here we present the first static structural and in situ studies of the formation of iron oxide (hematite) nanoparticles in a DES of choline chloride : urea where xurea = 0.67 (aka. reline) as an exemplar solvothermal reaction, and observe the effects of water on the r
Photoredox catalysis via consecutive 2LMCT- and 3MLCT-excitation of an Fe(iii/ii)-N-heterocyclic carbene complex
Fe-N-heterocyclic carbene (NHC) complexes attract increasing attention as photosensitisers and photoredox catalysts. Such applications generally rely on sufficiently long excited state lifetimes and efficient bimolecular quenching, which leads to there being few examples of successful usage of Fe-NHC complexes to date. Here, we have employed [Fe(iii)(btz)3]3+ (btz = (3,3′-dimethyl-1,1′-bis(p-tolyl
Semi-Crystalline and Amorphous Polyesters Derived from Biobased Tri-Aromatic Dicarboxylates and Containing Cleavable Acylhydrazone Units for Short-Loop Chemical Recycling
Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links
Photoredox Catalysis Driven by Visible Light and Iron N-Heterocyclic Carbene Complexes
Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. Traditionally, such PCs are based on scarce and expensive metals, such as ruthenium or iridium, in combination with polypyridyl ligands. Res
First record of bluish Podarcis muralis (LAURENTI, 1768)
Shifting realities: dislocating Palestinian Jerusalemites from the capital to the edge
Lefebvre’s ‘right to the city’ was an expression of a new politics of citizenship,residency and above all the right to urban life. We thus build our argument inthis paper on the Lefebvre concept and through the case study of Kufr Aqab, thenorthernmost neighbourhood of the occupied city of Jerusalem. In order tosystematically displace Palestinian Jerusalemites and to achieve the Judaisationof Jerus
Seasonal progression and differences in major floral resource use by bees and hoverflies in a diverse horticultural and agricultural landscape revealed by DNA metabarcoding
Gardens are important habitats for pollinators, providing floral resources and nesting sites. There are high levels of public support for growing ‘pollinator-friendly’ plants but while plant recommendation lists are available, they are usually inconsistent, poorly supported by scientific research and target a narrow group of pollinators. In order to supply the most appropriate resources, there is
Shortcuts for the circle
Let C be the unit circle in R2. We can view C as a plane graph whose vertices are all the points on C, and the distance between any two points on C is the length of the smaller arc between them. We consider a graph augmentation problem on C, where we want to place k⩾1 shortcuts on C such that the diameter of the resulting graph is minimized. We analyze for each k with 1⩽k⩽7 what the optimal set of
Production and characterization of Xanthosoma sagittifolium and Colocasia esculenta flours
The physical proximate composition and physicochemical characteristics, microbiological stability, and in vitro alpha-amylolysis rate of flours produced by conventional dehydration techniques of the edible portions of the aroids Xanthosoma sagittifolium and Colocasia esculenta were investigated. Flours from the edible portion of both tubers did not show significant statistical differences in moist
Recent advances on chiral partners and patterns and the thermal f0(500) in chiral restoration
We review recent results on chiral SU(2)L ×SU(2)R ≈ O(4) and U(1)A symmetry restoration in QCD. In particular, we discuss how Ward Identities allow one to derive general results on partner degeneration, which shed light on the distinction between the O(4) and O(4) ×U(1)A patterns of the chiral transition. For that purpose, susceptibilities associated with the O(4) and U(1)A symmetries are studied.
Analysis of column reactor results with organic decay by native organic microbiota and varying permeability
Field bio-remediation techniques (FBRT) can be a low cost method to avoid the removal of top layers of soil which are rich in organic matter and bio diversity. The use of native microorganisms in FBRT is preferable because non-indigenous species can transfer their genetic material to the environment with negative impacts on the local ecological equilibrium. Petroleum Produced Water (PPW) is an imp
Including the phosphorus cycle into the LPJ-GUESS dynamic global vegetation model (v4.1, r10994) – global patterns and temporal trends of N and P primary production limitation
Phosphorus (P) is a critical macronutrient for plant growth, often limiting plant production in areas where plant demand is higher than soil supply. In contrast to nitrogen (N), P cannot be sourced from the atmosphere; therefore, where it is rare, it becomes a strong constraint on primary production. Due to this, most dynamic global vegetation models (DGVMs) are incorporating a prognostic P cycle
The Wide Phenotypic Spectrum of L-2 Hydroxyglutaric Aciduria in Adults
Shared patterns in long-term dynamics of commons as institutions for collective action
We present an analysis of regulatory activities in historical commons offering a unique picture of their long-term institutional dynamics. The analysis took into account almost 3,800 regulatory activities in eighteen European commons in two countries across seven centuries. Despite differences in time and space, we found a shared pattern where an initial, highly-dynamic institutional-definition ph
Development of an automated flow-based spectrophotometric immunoassay for continuous detection of zearalenone
Considering the widespread contaminations of food products with mycotoxins, it is important to develop, robust, time- and cost-effective detection methods. We developed and optimized an immunoassay using a continuous flow system for the detection of zearalenone (ZEN). The assay was performed in a flow mode using an automated sequential injection system. Time for an assay cycle was 18 Min. Under op
Roadmap to functional characterization of the human intestinal microbiota in its interaction with the host
It is known for more than 100 years that the intestinal microbes are important for the host's health and the last decade this is being intensely studied with a focus on the mechanistic aspects. Among the fundamental functions of the intestinal microbiome are the priming of the immune system, the production of essential vitamins and the energy harvest from foods. By now, several dozens of diseases,
Negative properties of quantifiers in English and Swedish
In this paper we report the results from two small-scale studies on monotone decreasing (negative) quantifying expressions (QEs) and their negative polarity properties. Some approaches to QEs view polarity item licensing and clause polarity (affirmation/denial) as distinct phenomena. Here, we investigate if this distinction holds for monotone decreasing QEs. In two studies (one on English and one

The measurement of innovation is a challenging task for management accounting practitioners and researchers alike. To tackle this task, key performance indicators (KPIs) can be used to measure and follow up innovation. This case study shows how KPIs are used to measure innovation after strategic changes due to competitive pressures. The findings of this study indicate that KPIs in innovation are uMeasuring innovation is a challenging but essential task to improve business performance.
