Ru is an important catalyst in many types of reactions. Specifically, Ru is well known as the best monometallic catalyst for oxidation of carbon monoxide (CO) and has been practically used in residential fuel cell systems. However, Ru is a minor metal, and the supply risk often causes violent fluctuations in the price of Ru. Here, we report performance-improved and cost-reduced solid-solution alloy nanoparticles of the Cu-Ru system for CO oxidation. Over the whole composition range, all the CuxRu1-x nanoparticles exhibit significantly enhanced CO oxidation activities, even at 70 at% inexpensive Cu, compared to Ru nanoparticles...

The juxtaposition of a young city-state showing relative maturity as a rapidly aging society suffuses the population aging narrative in Singapore and places the "little red dot" on the spotlight of international aging. We first describe population aging in Singapore, including the characteristic events that shaped this demographic transition. We then detail the health care and socioeconomic ramifications of the rapid and significant shift to an aging society, followed by an overview of the main aging research areas in Singapore, including selected population-based data sets and the main thrust of leading aging research centers/institutes...

As global leaders, US nurses will have an increasingly recognized role and responsibility in shaping health care in all countries. They should be at the forefront of changing and improving health systems to achieve universal health. Currently, a major health care reform is underway that requires a shift in the professional nursing footprint of China's nurse leaders. These leaders must garner knowledge capital to reinforce ethics, regulations, and standards; use current best practices; implement a comprehensive performance evaluation process; and capture the spirit of caring within their health care environments...

The relationship that Indigenous Peoples have to the Canadian healthcare system makes the system's weaknesses and complexities obvious. The long-standing lack of consideration to the historical and contemporary realities of Indigenous Peoples has resulted in miscommunication, misunderstanding, mistrust and racism. Health leaders, including health authorities, across the province are thus challenged to ensure that culturally safe environments are available and culturally safe practices are being used. This article begins with an overview of contemporary social political contexts in which Indigenous individual and collective realities are situated...

A novel drug carrier is constructed by compositing hydrophilic hydroxypropyl-β-cyclodextrins (HP-β-CD) and carboxylated graphene nanomaterial (GO-COOH). Fourier transform infrared spectroscopy confirms that the two materials are successfully combined via chemical bonds. Further, a crosslinking agent of glutaraldehyde is applied to fabricate composite GO-COO-HP-β-CD nanospheres, as demonstrated by an atomic force microscope. Dexamethasone (DEX) is selected as the model drug, and the drug loading efficiency and water solubility of the nanospheres greatly increased...

ZnO grafted amorphous Fe2 O3 matrix (ZnO/Fe2 O3 ) was coupled with g-C3 N4 to synthesize heterojunction photocatalysts with a loosened multilayered structure. The ZnO/Fe2 O3 /g-C3 N4 exhibited enhanced photocatalytic performance in the degradation of sulfamethazine under visible-light irradiation (λ > 420 nm), with an optimum photocatalytic degradation rate approximately 3.0, 2.4 times that of pure g-C3 N4 and binary ZnO/g-C3 N4 . Moreover, the target sulfonamides spiked in actual surface water samples could be efficiently photodegraded by ZnO/Fe2 O3 /g-C3 N4 after 8 h of irradiation, demonstrating its practical potential...

Oxidative O2 -dependent biotransformations are promising for chemical synthesis, but their development to an efficiency required in fine chemical manufacturing has proven difficult. General problem for process engineering of these systems is that thermodynamic and kinetic limitations on supplying O2 to the enzymatic reaction combine to create a complex bottleneck on conversion efficiency. We show here that continuous flow (micro)reactor technology offers a comprehensive solution. It does so by expanding the process window to the medium pressure range (here: ≤ 34 bar) and thus enables biotransformations to be conducted in a single liquid phase at boosted concentrations of the dissolved O2 (here: up to 43 mM)...

Hydroquinone (HQ) is produced commercially from benzene by multi-step Hock-type processes with equivalent amounts of acetone as side-product. We describe an efficient biocatalytic alternative using the cytochrome P450-BM3 monooxygenase. Since the wildtype enzyme does not accept benzene, a semi-rational protein engineering strategy was developed. Highly active mutants were obtained which transform benzene in a one-pot sequence first into phenol and then regioselectively into HQ without any overoxidation. A computational study shows that the chemoselective oxidation of phenol by the P450-BM3 variant A82F/A328F leads to the regioselective formation of an epoxide intermediate at the C3=C4 double bond, which departs from the binding pocket and then undergoes fragmentation in aqueous medium with exclusive formation of HQ...

Useful insight into the evolution of genes and gene families can be provided by the analysis of all available genome datasets rather than just a few, which are usually those of model species. Handling and transforming such datasets into the desired format for downstream analyses is, however, often a difficult and time-consuming task for researchers without a background in informatics. Therefore, we present two simple and fast protocols for data preparation, using an easy-to-install, open-source, cross-platform software application with user-friendly, rich graphical user interface (SEDA; http://www...

Microplastics are recognized as a growing threat for the marine environment that may even affect areas generally considered pristine. In this work we surveyed the microplastic contamination in the Faafu Atoll (Maldives, Indian Ocean) across twelve sampling station, located either inside or outside the reef rim. Sediments and seawater samples were collected. Despite the remoteness of the atoll, the scarce local population and low touristic annual afflux, the detected average abundance were 0.32 ± 0.15 particles/m3 in the surface water and 22...

Healthcare reform efforts implemented to optimize primary and specialty care delivery require practices to undertake considerable transformation. To support change efforts, many private insurers and federal and state health-reform efforts provide practices and clinicians with access to practice-transformation facilitators. Healthcentric Advisors provides practice-transformation support and technical assistance to practices in Rhode Island and across New England. From this work we know that strategies and approaches to support transformation and achievement of program recognitions differ by practice characteristics, resource access, and patient panels...

The delivery of effective 21st-century multidisciplinary healthcare requires that clinicians focus on patient needs and concerns and are able to communicate compassionately and appropriately so that patient-practitioner trust is engendered. To develop interpersonal skills among healthcare providers, health professions education programs must build student competencies in the affective domain of learning. This paper seeks to investigate the efficacy of some of the contemporary strategies used to present and assess affective domain learning in health professions education, including the think-pair-share technique, reflective journaling, simulation and role play, motivational interviewing, and structured controversy...
