The sluggish kinetics and demand of high anodic potential are the bottlenecks for OER that severely hamper the deployment of water splitting modules for H 2 production. Although transition metal oxides based electrocatalysts have been envisioned as potential contender in this quest, but their low conductivity, instability and limited number of active sites are among the common impediments that need to be addressed to enhance their inherent catalytic potential for enhanced OER activity. Herein, we report the controlled assembly of transition metal oxides i.e., Cu@CuO x nanoclusters (NCs, ≈ 2nm) and Co@CoO x beaded nanoclusters (BNCs, ≈2nm) on thiol-functionalized graphene oxide nanosheets as novel and highly efficient electrocatalysts for OER. Thiol functionality was incorporated via selective epoxidation reaction on the surface of graphene oxide to achieve chemically exfoliated nanosheets to enhance its conductivity and trapping ability for metal oxides NCs. During electrocatalytic reaction, an overpotential of 290 mV and 310 mV is required to achieve a current density of 10 mA/cm 2 for BNCs and NCs respectively, while exhibiting long-term stability (≈50 h) in alkaline medium (1 M KOH) with no dissolution. Moreover, the smaller Tafel slopes (54 mV/dec for BNCs and 66 mV/dec for NCs), and a Faradic efficiency of ≈96 % indicate not only the selectivity but also the tailored heterogeneous electrons transfer rate that is essentially required for fast electrode kinetics. © 2020 WILEY-VCH Verlag GmbH & Co.

Liquid-phase synthesis methods are economical and environmentally-friendly with low energy consumption and volatile emissions, which have received much attention in the preparation of iron oxide nanostructured materials. Herein, the liquid-phase synthesis methods of iron oxide nanostructured materials including the co-precipitation method, microemulsion method, conventional hydrothermal and solvothermal methods, microwave-assisted heating method, sonolysis method, and other methods are summarized and reviewed. Many iron oxide nanostructured materials, self-assembled nanostructures, and nanocomposites have been successfully prepared, which are of great significance in enhancing their structure-dependent properties and applications. The specific roles of the liquid-phase chemical reaction parameters in regulating the chemical composition, structure, crystallinity, morphology, particle size, and dispersive behavior of the as-prepared iron oxide nanostructured materials are emphasized. The biomedical, environmental, and electrochemical energy storage applications of iron oxide nanostructured materials are discussed. Finally, challenges and perspectives are proposed for future investigations on the liquid-phase synthesis and applications of iron oxide nanostructured materials. © 2020 WILEY-VCH Verlag GmbH & Co.

This has also led to a steadily growing number of publications concerning the preparation of isolable and characterizable palladium(III) and palladium(IV) complexes. A variety of one-electron and two-electron oxidants have been employed to give access to high-oxidation-state Pd compounds. Undoubtedly, the study of these stoichiometric reactions has great implications for relevant Pd-mediated catalysis. In this mini-review, we focus on the synthetic approaches of structurally determined Pd III/IV complexes starting from their Pd II precursors, and the advances in this research area from early 2010 to late 2019 will be highlighted. Chemical oxidations exploiting various oxidizing agents including (i) hypervalent iodine reagents; (ii) halogens; (iii) electrophilic fluorination reagents; (iv) alkyl/aryl halides; (v) ferrocenium salts; (vi) peroxides/O 2 ; (vii) sulfonyl chlorides; and (viii) others are covered. A "greener" electro-oxidation manner has also been reviewed. © 2020 WILEY-VCH Verlag GmbH & Co. selleck chemicals llc KGaA, Weinheim.This study aimed to evaluate the effects of dietary guanidine acetic acid (GAA) supplementation on growth performance, carcass traits and the expression of muscle growth-related genes in finishing pigs. A total of 128 (81.03 ± 1.09 kg body weight) crossbred pigs (Duroc × Landrace ×Yorkshire) were blocked by body weight and allotted to 16 pens (eight pigs per pen), and pens were randomly assigned within blocks to one of five dietary treatments, with a basal diet (control group) or a basal diet supplemented with 0.03%, 0.06% and 0.09% GAA respectively. During the 60-day trial, GAA increased the average dairy gain (ADG) and average daily feed intake (ADFI) (p less then .05). The back fat thickness of pigs fed 0.06% GAA was lower than other groups (p less then .05). Pigs fed 0.06% GAA had improved lean meat percentage, loin muscle area, shear force and cross-sectional area of muscle fibre in comparison with control group (p less then .05). The drop loss and the muscle fibre density in pigs fed 0.06% GAA were lower than control (p less then .05). In addition, dietary GAA enhanced the expression of myosin heavy chain gene (MYH4), myogenic determination (Myod) and myogenic factor 5 (Myf5) in longissimus dorsi and carnitine palmitoyltransferase-1(CPT-1) in liver (p less then .05). Meanwhile, GAA decreased the expression of Myostatin in longissimus dorsi and fatty acid synthase (FAS) in liver (p less then .05). In conclusion, our results showed that appropriate dietary GAA supplementation (0.06%) promotes skeletal muscle development through changing myogenic gene expression and myofibre characteristics. © 2020 Blackwell Verlag GmbH.Linguistic and ethnic diversity is a feature of patient profiles at almost all public healthcare facilities in urban areas in Australia. Patients with limited proficiency in the socially dominant language - in this case Limited English proficiency (LEP) patients - commonly form a significant patient group in public healthcare settings. Communication barriers that exist between patients and healthcare professionals necessitate the provision of translation and interpreting (T&I) services. This study presents longitudinal data from Melbourne, Australia, on the provision of (T&I) services together with patient length of stay (LOS) and patient readmission rates over a 10-year period at a large, public healthcare provider. Patient LOS and patient readmission rates are key metrics for effective diagnosis and treatment of patients and commonly used to measure the performance of various aspects of healthcare provision. The augmentation of T&I services within a general policy of patient-centred care is shown to accompany decreased LOS and lower readmission rates for LEP patients. © 2020 John Wiley & Sons Ltd.Controlling the crystallisation of metal-organic frameworks (MOFs), network solids of metal ions or clusters connected by organic ligands, is often hindered by the significant number of synthetic variables inherent to their synthesis. Coordination modulation, the addition of monotopic competing ligands to solvothermal syntheses, can allow tuning of physical properties (particle size, porosity, surface chemistry), enhance crystallinity, and select desired phases, by modifying the kinetics of self-assembly, but its mechanism(s) are poorly understood. Herein, we use turbidity measurements to assess the effects of modulation on the solvothermal synthesis of the prototypical Zr terephthalate MOF UiO-66 and apply the knowledge gained to its rapid microwave synthesis. The studied experimental parameters - temperature, reagent concentration, reagent aging, metal precursor, water content, and modulator addition - all influence the time taken for onset of nucleation, and subsequently allow microwave synthesis of UiO-66 in as little as one minute. The simple, low cost turbidity measurements align closely with previously reported in situ synchrotron X-ray diffraction studies, proving their simplicity and utility for probing the nucleation of complex materials while offering significant insights to the synthetic chemist. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Hybridizing graphene and molecules possess a high potential for developing materials for new applications. However, new methods to characterize such hybrids must be developed. Herein, we present the wet-chemical non-covalent functionalization of graphene with cationic π-systems and characterize the interaction between graphene and the molecules in detail. A series of tricationic benzimidazolium salts with various steric demand and counterions was synthesized, characterized and used for the fabrication of graphene hybrids. Subsequently, the doping effects were studied. The molecules are adsorbed onto graphene and studied by Raman spectroscopy, XPS as well as ToF-SIMS. The charged π-systems show a p-doping effect on the underlying graphene. Consequently, the tricationic molecules are reduced via a partial electron transfer process from graphene, a process which is accompanied by the loss of counterions. DFT calculations support this hypothesis and the strong p-doping could be confirmed in fabricated monolayer graphene/hybride FET devices. The results are the basis to develop sensor applications, which are based on analyte/molecule interactions and effects on doping. © 2020 WILEY-VCH Verlag GmbH & Co.

With recent efforts to find effective non-opioid analgesics, ketamine has surfaced as a potential option for ED analgesia.1-3 While ketamine is typically used as a sedative agent, several studies have shown that when it is administered in sub-dissociative doses, both as a stand-alone agent and as an adjunct to opioids, it may also provide analgesia.4 Two recently published meta-analyses compared ketamine with opioid analgesics in adult ED patients with acute pain.

Despite this growth, the profession of genetic counseling has remained demographically homogenous. Promoting a culture of inclusivity that supports visible and invisible diversity and leveraging that culture not only expands perspectives represented in the field, but also helps foster equity in genetic services. This report summarizes the formation, implementation, and outcomes of the 2019 Diversity and Inclusion Task Force (TF) of the National Society of Genetic Counselors (NSGC), including the group's responses to their allotted charges from the NSGC Board of Directors. The recommendations generated by the TF aim to aid in the (1) establishment of infrastructure for ongoing diversity, inclusion, and equity (DEI) work by collaborating with a DEI organizational expert and forming a DEI advisory group within the NSGC, (2) development of specific short-term DEI initiatives, and (3) identification of seven areas of focus areas that must be addressed in order to create meaningful and measurable DEI improvements.
