The Li3PO4 modified LiFePO4/C and Li4P2O7 modified LiFePO4/C cathode materials were synthesized by in-situ synthesis method, respectively. Phase compositions and microstructures of the products were characterized by X-ray powder diffraction (XRD), scanning electronic microscope (SEM). Results indicate that Li3PO4 and Li4P2O7 can sufficiently coat on the LiFePO4 surface and does not alter LiFePO4 crystal structure. The electrochemical behavior of cathode materials was analyzed using galvanostatic measurement and cyclic voltammetry (CV)...

OBJECTIVE: The Care Transitions Intervention (CTI) has potential to improve the emergency department (ED)-to-home transition for older adults. Community paramedics may function as the CTI coaches; however, this requires the appropriate knowledge, skills, and attitudes, which they do not receive in traditional emergency medical services (EMS) education. This study aimed to define community paramedics' perceptions regarding their training needs to serve as CTI coaches supporting the ED-to-home transition...

PROBLEM: Patients and caregivers frequently report feeling ill-prepared during the transition from hospital to home. Given the privileged position nurses occupy within the health care setting, they are often an appropriate health care professional to lead the discharge process. We aimed to map what is currently known about nurse-led/facilitated discharge programs, interventions, models, or frameworks for the pediatric population. ELIGIBILITY CRITERIA: We conducted a scoping review following the Joanna Briggs Institute Methodology...

Shared decision making (SDM) is an effective health communication model designed to facilitate patient engagement in treatment decision making. In mental health, SDM has been applied and evaluated for medications decision making but less for its contribution to personal recovery and rehabilitation in psychiatric settings. The purpose of this pilot study was to assess the effect of SDM in choosing community psychiatric rehabilitation services before discharge from psychiatric hospitalization. A pre-post non-randomized design with two consecutive inpatient cohorts, SDM intervention (N = 51) and standard care (N = 50), was applied in two psychiatric hospitals in Israel...

Triboelectrification has been studied for over 2500 years, yet there is still a lack of fundamental understanding as to its origin. Given its utility in areas such as xerography, powder spray painting, and energy harvesting, many devices have been made to investigate triboelectrification at many length-scales, though few seek to additionally make use of triboluminescence: the emission of electromagnetic radiation immediately following a charge separation event. As devices for measuring triboelectrification became smaller and smaller, now measuring down to the atomic scale with atomic force microscope based designs, an appreciation for the collective and multi-scale nature of triboelectrification has perhaps abated...

Smart electrochromic windows integrated with electrochemical energy storage capacity are receiving increasing interest for green buildings. However, the fabrication of bifunctional devices that demonstrate high-rate capability with stable and desirable optical modulation still remains a great challenge. Herein, a facile sacrificial template-accelerated hydrolysis approach is presented to prepare a designed lithium-ion insertion-type material layer on a fluorine-doped tin oxide substrate, with TiO2 mesoporous nanotube array (MNTA) film as an example, with rapid Li-ion insertion kinetics and without sacrificing window transparency, to meet requirements...

PURPOSE OF STUDY: A currently proposed rule by the Centers for Medicare & Medicaid Services would require providers to devote more resources to discharge planning from hospitals to ensure the prioritization of patient preferences and goals in the discharge planning process. Annually, more than 3 million persons enter a nursing home in the United States, with the vast majority of patients coming directly from hospitals. Although early evidence suggests more family involvement than patient involvement in the discharge process, most of this work has relied on retrospective reports of the decision-making process postplacement...

Homogeneous SnO2 hollow spheres have been synthesized through a hydrothermal method without a template, followed by in situ polymerization of PANI. The resulting SnO2 hollow spheres were uniformly deposited onto the surface or embedded into the PANI nanofibers to form a SnO2-PANI network structure. As electrode materials, the SnO2-PANI composites exhibit greatly enhanced specific capacitance (477 F g-1 at a current density of 1 A g-1) and superior cycling performance (no capacitance loss after 3000 galvanostatic charge-discharge cycles)...

Semiconductor nanowire arrays promise rapid development of a new generation of lithium (Li) batteries because they can store more Li atoms than conventional crystals due to their large surface areas. During the charge-discharge process, the electrodes experience internal stresses that fatigue the material and limit the useful life of the battery. The study of the electronic and mechanical properties of lithiated nanowire arrays using theoretical models allows designing electrode materials that improve battery performance...

Lithium ion capacitors possess an ability to bridge the gap between lithium ion battery and supercapacitor. The main concern of fabricating lithium ion capacitors is poor rate capability and cyclic stability of the anode material which uses sluggish faradaic reactions to store an electric charge. Herein, we have fabricated high performance hybrid anode material based on carbon nanofibers (CNFs) and cobalt-nickel sulfide (CoNi2S4) nanoparticles via simple electrospinning and electrodeposition methods. Porous and high conducting CNF@CoNi2S4 electrode acts as an expressway network for electronic and ionic diffusion during charging-discharging processes...

Silicon has been intensively studied as an anode material for lithium-ion batteries (LIB) because of its exceptionally high specific capacity. However, silicon-based anode materials usually suffer from large volume change during the charge and discharge process, leading to subsequent pulverization of silicon, loss of electric contact, and continuous side reactions. These transformations cause poor cycle life and hinder the wide commercialization of silicon for LIBs. The lithiation and delithiation behaviors, and the interphase reaction mechanisms, are progressively studied and understood...

Binder-free nickle cobaltite on carbon nanofiber (NiCo2O4@CNF) anode for lithium ion batteries was prepared via a two-step procedure of electrospinning and electrodeposition. The CNF was obtained by annealing the electrospun poly-acrylonitrile (PAN) in the nitrogen (N2). The NiCo2O4 nanostructures were then grown on the CNF by electrodeposition, followed by annealing in the air. Experimental results showed vertically aligned NiCo2O4 nanosheets were uniformly grown on the surface of CNF, forming an interconnected network...

A lithium-sulfur (Li-S) battery is regarded as the most promising candidate for next generation energy storage systems, because of its high theoretical specific capacity (1675 mA h g-1) and specific energy (2500 W h kg-1), as well as the abundance, low cost and environmental benignity of sulfur. However, the soluble polysulfides Li2Sx (4 ≤ x ≤ 8) produced during the discharge process can cause the so-called "shuttle effect" and lead to low coulombic efficiency and rapid capacity fading of the batteries, which seriously restrict their practical application...
