This work reveals a new method of producing robust printed electronics that retain the advantages of rapid prototyping and three-dimensional fabrication while achieving the performance necessary for success within the aerospace and communications industries.As emerging materials for capacitor applications, antiferroelectric (AFE) materials possess high energy storage density. AFE single crystals are conducive to studying the physical mechanism of AFE response. However, the preparation of AFE single crystals is a huge and long-standing challenge. Herein, we report the effect of Na/La codoping on the energy storage properties and phase transition of Pb(Lu1/2Nb1/2)O3 (PLN) AFE single crystals. selleck An enhanced recoverable energy storage density of 4.81 J/cm3 with a high energy efficiency of 82.36% is obtained, which is much larger than that of the PbZrO3- and PLN-based AFE crystals. Two superlattice reflections, which stem from the A-site Pb2+ ions and the ordered B-site ions, are identified by X-ray diffraction and selected-area electron diffraction. The domain structures demonstrated a high temperature stability of the AFE phase. A secondary ferroelectric phase transition is induced after codoping, resulting in a sharp improvement of polarization (12.5 μC/cm2), which contributes to the enormous enhancement of energy storage density. This multiphase transition is explained using the modified Ginzburg-Landau-Devonshire phenomenology.Despite the large number of reports on the utilization of highly microporous solids, most relevant are metal-organic frameworks (MOFs), in different demanding applications, the successful hybridization of MOFs and moldable polymer matrices into flexible, water-permeable membranes exhibiting strong entanglement of the MOF and the polymer matrix properties is still lacking. We describe herein an efficient pathway to construct a mixed-matrix membrane (MMM) comprising a water-stable metal-organic framework (UiO-66-NH2), as the active sorbent, and cellulose acetate (CA), as the polymer matrix, to construct a flexible membrane for water treatment applications. The MOF@CA MMM demonstrated superior performance in terms of exceptional removal of organic dyes (both cationic and anionic species) as well as hexavalent Cr ions, compared to the control CA membrane. The recorded high uptake of the MOF@CA MMM for this wide array of contaminants demonstrated the accessibility of the MOF nanocages immobilized within the MMM, in contrast to the common perception that the polymer matrix might act as a physical barrier to block the accessibility of the MOF cages. The negative surface charge of the matrix exerted a notable action to affect the diffusion of the negatively charged contaminants to reach the active sorbent filler. Moreover, the formed membrane demonstrated high durability and recyclability with no detected loss of performance over numerous cycles. This approach outlines the ability to formulate one of the most water-stable MOFs, as exceptional microporous sorbent, into a usable membrane form compatible with real-life applications.Background People of Aboriginal (Indigenous) ancestry are more likely to experience traumatic spinal cord injury (TSCI) than other Canadians; however, outcome studies are limited. This study aims to compare Aboriginal and non-Aboriginal populations with acute TSCI with respect to preinjury baseline characteristics, injury severity, treatment, outcomes and length of stay. Methods This was a retrospective analysis of participants with a TSCI who were enrolled in the prospective Rick Hansen Spinal Cord Injury Registry (RHSCIR), Saskatoon site (Royal University Hospital), between Feb. 13, 2010, and Dec. 17, 2016. Demographic, injury and management data were assessed to identify any differences between the populations. Results Of the 159 patients admitted to Royal University Hospital with an acute TSCI during the study period, 62 provided consent and were included in the study. Of these, 21 self-identified as Aboriginal (33.9%) and 41 as non-Aboriginal (66.1%) on treatment intake forms. Compared with non-Aboriginal participants, Aboriginal participants were younger, had fewer medical comorbidities, had a similar severity of neurologic injury and had similar clinical outcomes. However, the time to discharge to the community was significantly longer for Aboriginal participants (median 104.0 v. 34.0 d, p = 0.016). Although 35% of non-Aboriginal participants were discharged home from the acute care site, no Aboriginal participants were transferred home directly. Conclusion This study suggests a need for better allocation of resources for transition to the community for Aboriginal people with a TSCI in Saskatchewan. We plan to assess outcomes from TSCI for Aboriginal people across Canada.Eosinophilic esophagitis (EoE) is a chronic allergen/immune-mediated disease leading to esophageal dysfunction. Food allergens play critical roles in the pathogenesis and treatment of EoE via different mechanisms. This study aimed to present the characteristics and evaluate the ability of skin prick test (SPT), skin prick to prick test (SPP) (IgE-mediated), and atopic patch test (APT) (cell-mediated) individually or simultaneously to diagnose food allergy in patients suffering from EoE. This prospective study was conducted on 58 patients with EoE. Seven patients (12.1%) were positive to only one, 3 (5.2%) were simultaneously positive to two, and 32 (55.2%) were simultaneously positive to three tests. Single and double sensitizations were totally 10.4% in IgE-mediated reactions, while 36.5% in cell-mediated reactions. In contrast, poly sensitization (>2 allergens) was 51.7% in IgE-mediated tests and 20.7% in the cell-mediated test. Multiple sensitization findings showed egg white, milk, yolk, and soy were the most frequent allergens. Our findings indicate that EoE is early onset and associated with multiple food sensitizations, particularly via IgE-mediated mechanisms. These immune-mediated responses encompass both IgE-mediated (SPT and SPP) and cell-mediated (APT) reactions simultaneously not individually. Therefore, employing multiple assays may strengthen the diagnosis of food sensitization.
