Electrochemical devices for energy conversion and storage are central for a sustainable economy. The performance of electrodes is driven by charge transfer across different layer materials and an understanding of the mechanistics is pivotal to gain improved efficiency. Here, we directly observe the transfer of photogenerated charge carriers in a photoanode made of hematite (α-Fe2O3) and a hydrous iridium oxide (IrOx) overlayer, which plays a key role in photoelectrochemical water oxidation. Through the use of operando X-ray absorption spectroscopy (XAS), we probe the change in occupancy of the Ir 5d levels during optical band gap excitation of α-Fe2O3...

C-H Borylation of arenes has been a subject of great current interest because of its atom-economy and the wide applicability of borylated products in value-added synthesis. A new bis(silylene)cobalt(II) complex bearing a bis(N-heterocyclic silylene)-pyridine pincer ligand (SiNSi) has been synthesized and structurally characterized. It enabled the regioselective catalytic C-H borylation of pyridines, furans and fluorinated arenes. Notably, it exhibited the complementary regioselectivity for the borylation of fluorinated arenes compared to previously known catalytic systems, demonstrating that N-heterocyclic silylene donors have enormous potential in metal-catalyzed catalytic applications...

BACKGROUND: Japan's stagnant economy has produced increasing income disparities, and the effect of poverty on health and health-care utilization is a significant issue. Co-payments could be a trade-off for patients when seeking medical care and limit health-care utilization. We sought primary care physicians' experiences in dealing with financially deprived patients and their perspectives about reducing co-payments by low-income patients. METHODS: We used a convergent mixed-methods approach in a mail survey; it was distributed to 1989 primary care physicians practicing in areas with the highest proportions of socially disadvantaged individuals in Tokyo...

In 2015, a record-breaking 3.5 million visitors-1 million from Canada alone-traveled to Cuba to explore its history, culture, natural splendor, and visit family. That same year, US President Barack Obama relaxed travel restrictions, giving general authorization for a dozen categories of legal travel by US citizens and residents. As a result, US visitors to the island ballooned by 80% between January 2015 and June 2016. And the numbers keep growing: the latest data show that foreign arrivals reached 4 million in 2016...

This paper looks at the integration of local authorities within the emergency preparedness, resilience and response (EPRR) system for health. The experience of the author, who works within this field for a local authority, is that current guidance is unclear and has affected integration of local authorities into the EPRR system. This paper therefore aims to identify why these issues exist and to assist in driving changes to current guidance, documentation and procedures.

Globally increasing energy demands and environmental concerns related to the use of fossil fuels have stimulated extensive research to identify new energy systems and economies that are sustainable, clean, low cost, and environmentally benign. Hydrogen generation from solar-driven water splitting is a promising strategy to store solar energy in chemical bonds. The subsequent combustion of hydrogen in fuel cells produces electric energy, and the only exhaust is water. These two reactions compose an ideal process to provide clean and sustainable energy...

While movie edition creates a discontinuity in audio-visual works for narrative and economy-of-storytelling reasons, eyeblink creates a discontinuity in visual perception for protective and cognitive reasons. We were interested in analyzing eyeblink rate linked to cinematographic edition styles. We created three video stimuli with different editing styles and analyzed spontaneous blink rate in participants (N = 40). We were also interested in looking for different perceptive patterns in blink rate related to media professionalization...

The theory of the treadmill of production highlights how the constant search for economic growth leads to advanced economies being stuck on a "treadmill," where their well-being is not improved by economic growth, yet the impacts of this pursuit of growth causes massive, unsustainable environmental damages. In interrogating the specific driving force that keeps the irrational system of the treadmill so powerfully in place, the theory of the treadmill of production focuses on how those who control the production process, corporations, are the primary agents driving the treadmill, while also highlighting how the state and workers generally continue to provide support for the treadmill's continued reproduction...

Reactive oxygen species (ROS), when combined with various delivery mechanisms, has the potential to become a powerful novel therapeutic agent against difficult-to-treat infections, especially those involving biofilm. It is important in the context of the global antibiotic resistance crisis. ROS is rapidly active in vitro against all Gram-positive and Gram-negative bacteria tested. ROS also has antifungal and antiviral properties. ROS prevents the formation of biofilms caused by a range of bacterial species in wounds and respiratory epithelium...

Composite materials with fibrous reinforcement often provide superior mechanical, thermal, electrical and optical properties than the matrix. Asbestos, carbon fibers and carbon nanotubes (CNTs) have been widely used in composites with profound impacts not only on technology and economy but also on human health and environment. A large number of studies have been dedicated to the release of fibrous particles from composites. Here we focus on the transformation of the fibrous fillers after their release, especially the change of the properties essential for the health impacts...

A new strategy for direct and highly efficient synthesis of 2,3'-bisindolin-3-ones has been developed via a gold/copper-co-catalyzed tandem reactions of 2-alkynylanilines using TBHP as the terminal oxidant and oxygen-atom source. The single-step process involves a novel tandem intermolecular nucleophilic addition, intramolecular cyclization/oxidative cross-dehydrogenative coupling where up to four new bonds and two indole rings were created simultaneously in one-pot manner. The reaction features a broad substrate scope, good functional group tolerance, and high atom-economy...

A novel and atom-economical synthesis of fully substituted 4-aminoimidazoles via gold-catalyzed selective [3 + 2] annulation of 1,2,4-oxadiazoles with ynamides is reported. This protocol represents a new strategy to access α-imino gold carbenes, which corresponds to an unprecedented intermolecular transfer of N-acylimino nitrenes to ynamides. Moreover, the reaction proceeds with 100% atom economy, exhibits good functional group tolerance, and can be conducted in gram scale.

EDITORIAL
Raman Kumar, Pritam Roy
Amid the global push for Universal Health Coverage (UHC), the agenda is being set for India's health care. In the absence of a constitutional mandate, a national policy and citizen-led political demand for UHC, there exist specific risks in rushing toward its implementation in India. As the debate of UHC continues, the health-care delivery system in India is at cross roads. UHC in India could take two different trajectories. The first one takes India toward becoming "Global Bazaar" of morbidity and ill health, founded on the pillars of a vibrant rapidly multiplying healthcare industry...

Spiroplasma eriocheiris is a pathogen that causes mass mortality in Chinese mitten crab, Eriocheir sinensis. S. eriocheiris causes tremor disease and infects almost all of the artificial breeding crustaceans, resulting in disastrous effects on the aquaculture economy in China. S. eriocheiris is a wall-less helical bacterium, measuring 2.0 to 10.0 μm long, and can swim up to 5 μm per second in a viscous medium without flagella by switching the cell helicity at a kink traveling from the front to the tail. In this study, we showed that S...

: The use of textile meshes in hernia repair is widespread in visceral surgery. Though, mesh infection is a complication that may prolong the patient recovery period and consequently presents an impact on public health economy. Such concern can be avoided thanks to a local and extended antibiotic release on the operative site. In recent developments, poly-L-lactic acid (PLLA) has been used in complement of polyethyleneterephthalate (Dacron(®)) (PET) or polypropylene (PP) yarns in the manufacture of semi-resorbable parietal implants...

Exploitation of marine fishes is the main source of several life-supporting feed compounds such as proteins, lipids, and carbohydrates that maintain the production of most trading marine organisms by aquaculture. However, at this rate the marine inventory will go to the end soon, since fishery resources are finite. In this sense, the availability of the principal ingredients obtained from marine fishes is going to decrease considerably, increasing the diet prices and affecting the economy of this activity. Therefore, aquaculture industry needs to find nonexpensive land unconventional resources of protein, carbohydrates, and lipids and use bacterial probiotics to improve digestion-assimilation of these unfamiliar compounds...
