The development of rechargeable batteries with high performance is considered to be a feasible way to satisfy the increasing needs of electric vehicles and portable devices. It is of vital importance to design electrodes with high electrochemical performance and to understand the nature of the electrode/electrolyte interfaces during battery operation, which allows a direct observation of the complicated chemical and physical processes within the electrodes and electrolyte, and thus provides real-time information for further design and optimization of the battery performance...

BACKGROUND: The proposed National Health Insurance policy for South Africa (SA) requires hospitals to maintain high-quality International Statistical Classification of Diseases (ICD) codes for patient records. While considerable strides had been made to improve ICD coding coverage by digitising the discharge process in the Western Cape Province, further intervention was required to improve data quality. The aim of this controlled before-and-after study was to evaluate the impact of a clinician training and support initiative to improve ICD coding quality...

Transition metal dichalcogenides such as MoS2 and VSe2 have emerged as promising catalysts for the hydrogen evolution reaction (HER). Substantial work has been devoted to optimizing the catalytic performance by constructing materials with specific phases and morphology. However, the optimization of adsorption/desorption process in HER is rare. Herein, we concentrate on tuning the dynamics of the adsorption process in HER by applying a back gate voltage to the pristine VSe2 nanosheet. The back gate voltage induces the redistribution of the ions at the electrolyte-VSe2 nanosheet interface, which realizes the enhanced electron transport process and facilitates the rate-limiting step (discharge process) under HER condition...

Rational synthesis of flexible electrodes is crucial to rapid growth of functional materials for energy-storage systems. Herein, a controllable fabrication is reported for the self-supported structure of CuCo2 O4 nanodots (≈3 nm) delicately inserted into N-doped carbon nanofibers (named as 3-CCO@C); this composite is first used as binder-free anode for sodium-ion batteries (SIBs). Benefiting from the synergetic effect of ultrasmall CuCo2 O4 nanoparticles and a tailored N-doped carbon matrix, the 3-CCO@C composite exhibits high cycling stability (capacity of 314 mA h g(-1) at 1000 mA g(-1) after 1000 cycles) and high rate capability (296 mA h g(-1) , even at 5000 mA g(-1) )...

OBJECTIVES: Medication nonadherence is prevalent and associated with adverse outcomes, including hospital readmissions. Outpatient pharmacies within health systems are well positioned to intervene and enhance the discharge process by ensuring that patients leave the hospital with all discharge medications. The goal of this study was to evaluate whether a simply designed discharge prescription program (DPP) could reduce readmission rates and increase patient satisfaction scores for participants versus patients who did not participate...

Discharging patients from the hospital is a complex process, and preventing avoidable readmissions has the potential to improve both the quality of life for patients and the financial sustainability of the healthcare system (Alper et al. 2016). Improving the discharge process is one method to mitigate readmission to the hospital. Historically, St. Thomas Elgin General Hospital (STEGH) consistently experienced higher-than-expected readmission rates, and only 41% of discharge summaries were sent from the hospital to the community primary care within 48 hours...

Two-dimensional stable metallic 1T-MoSe2 with expanded interlayer spacing of 10.0 Å in situ grown on SWCNTs film is fabricated via a one-step solvothermal method. Combined with X-ray absorption near-edge structures, our characterization reveals that such 1T-MoSe2 and single-walled carbon nanotubes (abbreviated as 1T-MoSe2/SWCNTs) hybridized structure can provide strong electrical and chemical coupling between 1T-MoSe2 nanosheets and SWCNT film in a form of C-O-Mo bonding, which significantly benefits a high-efficiency electron/ion transport pathway and structural stability, thus directly enabling high-performance lithium storage properties...

Interconnected LiCuVO4 networks were synthesized through a facile surfactant-assisted approach. Detailed investigations on the lithium storage mechanism manifest that metallic Cu nanoparticles are generated in situ during the first discharge process and remain mostly intact in the following cycles, thereby enhancing conductivity of the electrode. The interconnected networks with submicron sized primary particles endow the LiCuVO4 with a large amount of active sites and thus high capacitive charge storage. Benefiting from a peculiar structure, the resultant interconnected LiCuVO4 networks deliver extraordinary rate performance (216 mA h g(-1) up to 10 A g(-1)) and ultralong cycling stability (∼85% capacity retention after 5000 cycles at 5 A g(-1))...

Electric field tuning of magnetism is one of the most intensely pursued research topics of recent times aiming at the development of new-generation low-power spintronics and microelectronics. However, a reversible magnetoelectric effect with an on/off ratio suitable for easy and precise device operation is yet to be achieved. Here we propose a novel route to robustly tune magnetism via the charging/discharging processes of hybrid supercapacitors, which involve electrostatic (electric-double-layer capacitance) and electrochemical (pseudocapacitance) doping...

The role of lithium salts in determining the discharge capacity of Li-O2 batteries has been highlighted in several recent studies; however, questions pertaining to their effect on the cathode surface and in the solution phase still remain unanswered. We conducted galvanostatic discharge experiments with different compositions of a binary mixture of 1 M of LiNO3 and LiTFSI in tetraglyme (TEGDME) as the electrolyte and analyzed the discharge products using techniques such as FT-IR, Raman spectroscopy, and SEM...

Nickel hydroxide (Ni(OH)2) has been regarded as a potential next-generation electrode material for supercapacitor owing to its attractive high theoretical capacitance. However, practical application of Ni(OH)2 is hindered by its lower cycling life. To overcome the inherent defects, herein we demonstrate a unique interconnected honeycomb structure of g-C3N4 and Ni(OH)2 synthesized by an environmentally friendly one-step method. In this work, g-C3N4 has excellent chemical stability and supports a perpendicular charge-transporting direction in charge-discharge process, facilitating electron transportation along that direction...

Cobalt hydroxide is a promising electrode material for supercapacitors due to the high capacitance and long cyclability. However, the energy storage/conversion mechanism of cobalt hydroxide is still vague at the atomic level. Here we shed light on how cobalt hydroxide functions as a supercapacitor electrode at operando conditions. We find that the high specific capacitance and long cycling life of cobalt hydroxide involve a complete modification of the electrode morphology, which is usually believed to be unfavourable but in fact has little influence on the performance...

A hierarchical mesoporous carbon foam (ECF) with an interconnected micro-/mesoporous architecture was prepared and used as a binder-free, low-cost, high-performance anode for lithium ion batteries. Due to its high specific surface area (980.6 m(2)/g), high porosity (99.6%), light weight (5 mg/cm(3)) and narrow pore size distribution (~2 to 5 nm), the ECF anode exhibited a high reversible specific capacity of 455 mAh/g. Experimental results also demonstrated that the anode thickness significantly influence the specific capacity of the battery...

OBJECTIVES: Patients are 30% less likely to be readmitted or visit the emergency department if they have a clear understanding of their discharge instructions. A standardized approach to a hospital discharge plan has not been universally implemented, however. Our goal was to increase patients' comprehension of discharge instructions by implementing a standardized patient-centered discharge planning protocol that uses a physician team member to explain these plans. METHODS: This was a prospective study that included all of the patients discharged from an inpatient medical teaching service in a community-based hospital during the study period...

OBJECTIVES: Healthcare expenditures in the United States have increased exponentially and hospital care accounts for one-third of these costs. Approximately 18% of hospitalized Medicare beneficiaries are being readmitted to the hospital within 30 days. Engaging patients in the discharge process can help better identify patients' postdischarge needs and implement more effective readmission prevention strategies. The objective of our study was to identify the factors that contribute to hospital readmission as seen from patients' perspectives in a large urban community hospital...
