Those defects are assigned to be negatively charged defects. The results open a new route to develop high-performance and wavelength-tunable LED devices for future advanced optoelectronic applications.<br /><br /> To describe and compare the clinical nurse specialist core competency use in Finland, Denmark and Iceland.<br /><br /> Clinical nurse specialist roles were first developed more than 60years ago in the United States. Within the Nordic countries, the clinical nurse specialist role emerged around 2000. There is scarcity of clinical nurse specialist competency descriptions outside of North America, and research has been limited to examine or validate established competencies across different countries.<br /><br /> A descriptive correlational study.<br /><br /> An online survey was conducted from May to September 2019. A population sample of clinical nurse specialists in Finland, Denmark and Iceland was recruited. A validated self-report questionnaire of clinical nurse specialist competencies was used. The data were analysed using descriptive and inferential statistics, and the STROBE checklist was used as the reporting guideline.<br /><br /> A total sample of 184clinical nurse specialists, 52 from Finland, 95 from Denmark and 37 from Iceland, particind evaluation as well as inform post-graduate education.<br /><br />The CNS competency scale may be utilised in benchmarking clinical nurse specialist roles and practice within and across countries. The long-term goal for the competency descriptions is to enhance the clinical nurse specialist role clarity, integration and evaluation as well as inform post-graduate education.<br /><br /> This study's aim is to examine what matters to nursing home residents with dementia by exploring their perceptions of nursing home health care through the conceptual lens of person-centred care.<br /><br /> Dementia is a major contributor to nursing home placement. To understand the meaning of living with dementia, the inclusion of persons with dementia in research studies is essential.<br /><br /> In total, 35 in-depth qualitative interviews were conducted with people who have dementia and live in nursing homes. A thematic analysis was applied to analyse the data. Checklist for qualitative studies Consolidated Criteria for Reporting Qualitative Research (COREQ) https//www.equator-network.org/reporting-guidelines/coreq/ RESULTS The analysis revealed one overarching theme with four sub-themes. Different matchings of person-centred care and routines in health care being the overarching theme. The four sub-themes were as follows (a) understanding of the interplay between disabilities and ageing; (b) participating based on one's onance.<br /><br />Based on the residents' statements, the results contribute to the fields of dementia education, health-care provision and policy-making and may be used to achieve person-centredness and governance.The diversity, complexity, and heterogeneity of malignant tumor seriously undermine the efficiency of mono-modal treatment. Recently, multi-modal therapeutics with enhanced antitumor efficiencies have attracted increasing attention. However, designing a nanotherapeutic platform with uniform morphology in nanoscale that integrates with efficient chem-/sono-/photo-trimodal tumor therapies is still a great challenge. Here, new and facile Pd-single-atom coordinated porphyrin-based polymeric networks as biocatalysts, namely, Pd-Pta/Por, for chem-/sono-/photo-trimodal tumor therapies are designed. The atomic morphology and chemical structure analysis prove that the biocatalyst consists of atomic Pd-N coordination networks with a Pd-N2 -Cl2 catalytic center. The characterization of peroxidase-like catalytic activities displays that the Pd-Pta/Por can generate abundant •OH radicals for chemodynamic therapies. The ultrasound irradiation or laser excitation can significantly boost the catalytic production of 1 O2 by the porphyrin-based sono-/photosensitizers to achieve combined sono-/photodynamic therapies. The superior catalytic production of •OH is further verified by density functional theory calculation. Finally, the corresponding in vitro and in vivo experiments have demonstrated their synergistic chem-/sono-/photo-trimodal antitumor efficacies. It is believed that this study provides new promising single-atom-coordinated polymeric networks with highly efficient biocatalytic sites and synergistic trimodal therapeutic effects, which may inspire many new findings in reactive oxygen species-related biological applications across broad therapeutics and biomedical fields.Metal halide perovskite nanocrystals (PNCs) have recently garnered tremendous research interest due to their unique optoelectronic properties and promising applications in photovoltaics and optoelectronics. Metal halide PNCs can be combined with polymers to create nanocomposites that carry an array of advantageous characteristics. The polymer matrix can bestow stability, stretchability, and solution-processability while the PNCs maintain their size-, shape- and composition-dependent optoelectronic properties. As such, these nanocomposites possess great promise for next-generation displays, lighting, sensing, biomedical technologies, and energy conversion. The recent advances in metal halide PNC/polymer nanocomposites are summarized here. First, a variety of synthetic strategies for crafting PNC/polymer nanocomposites are discussed. [https://www.selleckchem.com/products/azd9291.html AZD9291] Second, their array of intriguing properties is examined. Third, the broad range of applications of PNC/polymer nanocomposites is highlighted, including light-emitting diodes (LEDs), lasers, and scintillators. Finally, an outlook on future research directions and challenges in this rapidly evolving field are presented.Single-component materials with white-light emission are ideal for lighting applications. However, it is very challenging to achieve white luminescence in single-dopant activated solid phosphors. Herein, white NaLi3 Si1- x O4 Eu2+ materials are designed via defect engineering and synthesized by reducing the Si content (0.15 ≤ x ≤ 0.25). Stochiometric NaLi3 SiO4 Eu2+ exhibits a narrow-band blue emission at 469 nm, ascribed to the 5d → 4f transition of Eu2+ at highly symmetric cuboid Na sites, while samples with Si content reduced by 15-25% display white emission with two peaks at 472 nm and 585 nm. The newly appeared broadband yellow peak arises from charge-transfer transitions involving Eu2+ and nearby defects, as verified by an unusual bandwidth, a large Stokes shift, and a long decay time. A single-component white light-emitting diode device is fabricated by employing a white phosphor to demonstrate a color-rendering index of 82.9. This result provides a new design strategy for single-component white-light materials with broad-band defect-induced charge-transfer emission.
