We investigated the oxygen reduction reaction (ORR) mechanism on Pt nanoparticles (NPs) dispersed on several carbon blacks with various physicochemical properties ( i.e. specific surface ranging from 80 to 900 m 2 g -1 , different graphitization degree, etc .). Using the kinetic isotope effect (KIE) along with various electrochemical characterizations, we determined that the rate determining step (RDS) of the ORR is a proton-independent step when the density of Pt NPs on the surface of the carbon support is high. Upon decrease of the density of Pt NPs on the surface, the RDS of the ORR starts involving a proton, as denoted by an increase of the KIE > 1.This underlined the critical role played by the carbon support in ultra-low loading Pt-based electrocatalysts, which presents a low density of Pt NPs on their surface. © 2020 WILEY-VCH Verlag GmbH & Co.

They are also well-known ornamental plants that have economic value in the perfume industry. The main obvious diagnostic difference between the different species is based on the morphology of the flowers. The flowering cycle is very short as well as the persistence of the fully opened flowers extends for a few days only. Moreover, the climatic conditions significantly causes fluctuation in their blooming time from year to year. This makes the morphological discrimination very difficult. The discrimination of different iris species is of a great importance, as each species is reported to possess different folk medicinal activities. OBJECTIVES Finding genetic and metabolic markers for differentiation between Iris confusa Sealy (Subgen. Limniris Sect. Lophiris), I. pseudacorus L. (Subgen. Limniris Sect. Limniris) and I. germanica L. (Subgen. Iris Sect. Iris) on levels other than traditional taxonomic features. MATERIAL AND METHODS Inter-simple sequence repeat (ISSR) and gas chromatography-mass spectrometry (GC-MS) analyses were performed. RESULTS The highest similarity was found between I. pseudacorus L. and I. germanica L. and the least similarity was between I. confusa Sealy and I. pseudacorus L. The metabolic profiling of the leaves confirmed genetic profiling discriminating I. confusa from the other two species. The primary metabolites of the underground parts showed clear discrimination between the three species. CONCLUSIONS This study represents the sole complete map for distinguishing the three Iris species on genetic and metabolic bases. © 2020 John Wiley & Sons, Ltd.Chiral optical metamaterials with delicate structures are in high demand in various fields due to their strong light-matter interactions. Recently, a scalable strategy for the synthesis of chiral plasmonic nanoparticles using amino acids and peptides has been reported. In this work, three-dimensional chiral gold nanoparticles using dipeptide γ-Glu-Cys and Cys-Gly were synthesized and analyzed from a crystallographic perspective. The γ-Glu-Cys-directed nanoparticles showed a cube-like outline with a protruded chiral wing. Meanwhile, the nanoparticles synthesized with Cys-Gly exhibited a rhombic dodecahedron-like outline with curved edges and elliptical cavities on each face. Intermediate morphology analysis indicated that γ-Glu-Cys generated an intermediate morphology of concave hexoctahedron, while Cys-Gly formed a concave rhombic dodecahedron. Nanoparticles synthesized with Cys-Gly were named 432 helicoid V due to their unique morphology and growth pathway. © 2020 WILEY-VCH Verlag GmbH & Co.

Using acute stroke as an example, we aim to identify critical junctures for patient-centeredness along the acute care pathway from the perspectives of patients, relatives and staff. METHODS We conducted a qualitative multi-method study including 27 non-participant observations and 37 semi-structured interviews with patients, relatives and staff. We defined junctures as critical when mentioned (as problematic) in two or three information sources (i.e. observations, staff interviews, or patient and relative interviews), as potentially critical when mentioned in one, and as uncritical when not mentioned. RESULTS Post-procedure communication after thrombectomy, patients' stay at the stroke unit and decision-making around transfer, discharge and rehabilitation were identified as critical junctures for patient-centeredness. Arrival at the emergency department and the (thrombectomy) treatment itself were identified as uncritical junctures, while history-taking and treatment preparation, the treatment decision, and patients' stay at the intensive care unit were identified as potentially critical junctures. CONCLUSIONS In acute stroke care, patients, relatives and staff prioritise fast over patient-centred decision-making in the most time-critical phases, especially before and during treatment. This is reversed after the procedure, when difficulties arise implementing a patient-centred approach in clinical practice. To improve patient-centeredness where it is most needed, clear guidelines and accessible resources are recommended. Future research should investigate whether insights from acute phases of stroke care are applicable to other neurological conditions as well. This article is protected by copyright.

However, the relationship between genetic factors and mechanisms is not fully understood. The aim of the study was to further clarify the relationship between ARC and genetic mechanisms in East Asian populations and to elucidate the pathogenesis. METHODS The study collected 191 sporadic cataracts and 208 healthy people from the eastern provinces of China, with an average age of about 60 years. selleck kinase inhibitor All participants were subjected to a comprehensive ophthalmic clinical examination and peripheral blood samples were collected and their genomic DNA was extracted. Mutations were screened among 792 candidate genes to enhance understanding of the disease through targeted capture and high-throughput sequencing. RESULTS We identified novel candidate susceptibility gene, which may serve as a potential susceptibility factor leading to an increase in the incidence of age-related cataracts. Three novel loci are associated with age-related cataracts significant significance rs129882 in DBH (p = 5.
