It is essential to synthesize low-cost, earth-abundant bifunctional electrocatalysts
 for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for
 water electrolysis. Herein, we present a one-step sulfurization method to fabricate
 Ni3S2 nanowires directly grown on Ni foam (Ni3S2 NWs/Ni) as such an electrocatalyst.
 This synthetic strategy has several advantages including facile preparation, low cost
 and even can be expanded to large-scale preparation in the practical application...

The local phonon modes in a Coulomb crystal of trapped ions can represent a Hubbard system of coupled bosons. We selectively prepare single excitations at each site and observe free hopping of a boson between sites, mediated by the long-range Coulomb interaction between ions. We then implement phonon blockades on targeted sites by driving a Jaynes-Cummings interaction on individually addressed ions to couple their internal spin to the local phonon mode. The resulting dressed states have energy splittings that can be tuned to suppress phonon hopping into the site...

Two-dimensional (2D) microdroplet arrays with indexed sample concentration gradients have been receiving considerable attention for high-throughput biological and medical analyses. However, the preparation of such an array by conventional methods mandates precise pipetting and/or pumping. In this paper, we introduce a method to spontaneously generate 2D-arrayed aqueous droplets using a well array, for which coarse pipetting is sufficient. The wells are connected in rows and columns via narrow channels. Aqueous solutions impregnated in the well array are split into droplets in every single well as a subsequently introduced immiscible solvent self-propagates and divides the solution at the channels...

Post-translational K63-linked poly-ubiquitination of AKT is required for its membrane recruitment and phosphorylation dependent activation in response to growth-factor stimulation. Current assays for target specific poly-ubiquitination involve cumbersome enzymatic preparations and semi-quantitative readouts. We have engineered a reporter that can quantitatively and in a target specific manner report on AKT-directed K63-polyubiquitination (K63UbR) in live cells. The reporter constitutes the AKT-derived poly-ubiquitination substrate peptide, a K63 poly-ubiquitin binding domain (UBD) as well as the split luciferase protein complementation domains...

BACKGROUND AND OBJECTIVES: In Canada, few family physicians (FPs) perform endoscopy. Conflicting evidence exists on the quality of endoscopy performed by Canadian FPs, which may be explained by differing skillsets of these endoscopists. The objective of this study was to perform the first exploration of the practice, skills, and knowledge of Canadian FP endoscopists. METHODS: A cross-sectional survey, including direct knowledge test, was used. RESULTS: Twenty Canadian FP endoscopists completed the survey...

OBJECTIVES: Split dose of 4 l polyethylene glycol (PEG) is currently the standard regimen for bowel preparation (BP). However, it may be unnecessary for patients without high risks (e.g., old age, constipation, and diabetes, and so on) for inadequate BP. The study aimed to compare the efficacy of bowel cleansing between low-risk patients receiving same-day, single dose of low-volume (SSL) PEG vs. standard regimen. METHODS: This prospective, randomized, observer-blinded, non-inferiority study enrolled low-risk patients in three centers...

This paper considers the impact of gendered norms on decision-making for wildfire preparation and response at the household level. Focusing on Australia, it provides a theoretical thematic analysis of data acquired in 107 interviews with residents of nine different localities. It builds on existing research on gender and disaster, as well as on decision-making and wildfires, and analyses the narratives that centre on 'split' households plans (where a male partner plans to stay and a female partner plans to evacuate) and disagreements within heterosexual couples as to an appropriate wildfire safety plan...

The iron(IV) oxido complex [(tmc)Fe=O(OTf)]OTf with the macrocyclic ligand 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclo-tetradecane (tmc) has been synthesized using ozone as an oxidant. By adding water to this compound the complex [(H2O)(tmc)Fe=O)](OTf)2 could be prepared. This complex is important in regard to a better understanding of the reactivity of Fe(IV) oxido complexes. Mössbauer measurements using the solid compound showed an isomer shift of = 0.19 mms-1 and a quadrupole splitting EQ = 1.38 mms-1 confirming the high valent Fe(IV) state...

Background: A split-dose (SD) regimen is crucial for colonoscopy quality. Compliance with SD for early morning colonoscopy is generally poor. The present study evaluated whether pre-colonoscopy counselling, in addition to a dedicated leaflet, might increase SD uptake. Methods: Consecutive 50-69-year-old patients undergoing screening colonoscopy before 10 a.m. were randomized to either receive written information only on bowel preparation (Written Group, WG) or written and oral instructions (Written and Oral Group, WaOG)...

Developing highly efficient oxygen evolution reaction (OER) electrocatalysts is critical to the cost-effective generation of clean fuels. Transition-metal selenides have been proposed to be OER catalyst alternatives to noble metal based catalysts, but generally exhibit limited electrocatalytic activity. We here report hierarchical Fe-doped Ni3 Se4 ((Ni,Fe)3 Se4 ) ultrathin nanosheets as an efficient electrocatalyst for OER in alkaline electrolytes. The preparation involves a solvothermal synthesis and a topotactic conversion process...

Explantation of a left ventricular assist device (LVAD) may be challenging even in the most experienced hands. We aim to describe the technique for explantation of an LVAD together with the heart as applicable to all contemporary implantable mechanical assist devices. In order to ensure safe explantation, particular care must be taken at three distinct stages: at the time of LVAD implantation, at pre-transplant assessment and at the time of heart transplantation. The preparation for a safe explantation at LVAD implantation includes positioning the driveline and the outflow graft away from the back of the sternum to ensure protection from injury during re-entry into the chest...

An Ar atmospheric treatment is rationally used to etch and activate hematite nanoflakes (NFs) as photoanodes toward enhanced photoelectrochemical water oxidation. The formation of a highly ordered hematite nanorods (NRs) array containing a high density of oxygen vacancy is successfully prepared through in situ reduction of NFs in Ar atmosphere. Furthermore, a hematite (104) plane and an iron suboxide layer at the absorber/back-contact interface are formed. The material defects produced by a thermal oxidation method can be critical for the morphology transformation from 2D NFs to 1D NRs...

Graphitic carbon nitride (g-CN) is one potential metal-free photocatalyst. The photocatalytic mechanism of g-CN is involved with its building unit heptazine ring. Melem is the simplest heptazine-based compound and g-CN is its polymeric product. Thus, studies on the photophysical property of melem will help to understand the photocatalytic mechanism of heptazine-based materials. In this work, we systematically explored the spectroscopic features of melem through measuring its absorption spectrum, fluorescence spectrum and fluorescence decay, respectively...

Hollow nanostructures with mesoporous shells are attractive for their advantageous structure-dependent high-efficiency electrochemical catalytic performances. In this work, a novel nanostructure of Fe-doped CoP hollow triangle plate arrays (Fe-CoP HTPAs) with unique mesoporous shells is designed and synthesized through a room-temperature postsynthetic ligand exchange reaction followed by a facile phosphorization treatment. The mild postsynthetic ligand exchange reaction of the presynthesized ZIF-67 TPAs with K4 [Fe(CN)6 ] in an aqueous solution at room temperature is of critical importance in achieving the final hollow nanostructure, which results in the production of CoFe(II)-PBA HTPAs that not only determine the formation of the interior voids in the nanostructure, but also provide the doping of Fe atoms to the CoP lattice...
