In this work, we report methods to quantify and minimize the interfacial resistance for Li ion transport, Rinterface, between a model polymer electrolyte, poly(ethylene oxide) + LiCF3SO3 (PE), Li+-conducting ceramic LICGC from Ohara Corporation. By constructing PE–ceramic–PE trilayer cell, found Rinterface be very large, 1.2 kΩ·cm2 at 30 °C, accounting 66% of total cell resistance. When dimethyl carbonate, loose-binding solvent Li+, was introduced into trilayer, decreased essentially zero....
Single-ion-conducting polymer electrolytes are attractive to use in lithium batteries as the transference number of cation approaches unity. This helps prevent concentration gradients across electrolyte, which can result dendrite formation. The addition ceramic particles at high loadings increase mechanical strength polymer, also help suppress Here, a single-ion-conducting electrolyte is blended with lithium-conducting oxide make composite electrolyte. studied comparison containing freely...
TiO2 nanotube arrays (NTAs) on transparent conducting oxides (TCO) have attracted great attention due to the potential application in dye-sensitized solar cells (DSCs). Here, we introduce template-assisted process for direct fabrication of aligned NTAs TCO substrates, involving layer-by-layer adsorption and reaction (LBL-AR) assembled coating ZnO nanorods (NR). Key factors microstructures are analyzed, geometry effects performance electron transport properties DSCs investigated by using...
In this work, the properties of univalent, that is, Li+, Na+, NH4+, and TEA+ form perfluorosulfonate (PFSA) membranes are studied compared to H+ materials. Properties these polymer including water uptake, density conductivity, were investigated for exposed various activity levels. The uptake by decreased in order > Li+ Na+ NH4+ TEA+, same as hydration enthalpy (absolute values) cations. Conductivity values did not strictly follow order, indicating importance different factors besides level....
Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an important disease in Canada. The worldwide genetic structure of Pst populations have been characterized, excluding Here, we elucidated the western Canadian population using molecular markers, revealing presence four divergent lineages with predominantly clonal structure. In context, two previously reported were identified: PstS0 (22%), representing old Northwestern-European and PstS1 (35%), invasive...
A binuclear ruthenium(II) dimer (BiRD) bridged by an alkene linker was synthesized that labile to reactive oxygen species generated another photosensitizer. Compared the monomeric Ru(II) complex, BiRD had attenuated fluorescence and singlet production which could be restored a longer-wavelength This two-step amplification strategy demonstrates proof-of-principal for photosensitization chain-reactions.
Objective This paper aims to investigate whether machine learning (ML) can be used predict the state of pulmonary hypertension (PH), including pre-capillary and post-capillary, from echocardiographic data.Methods Two hundred seventy-five patients with PH who underwent both echocardiography right heart catheterization were included in study. Mean artery pressure, wedge pressure measured by as criteria for judging post-capillary PH. Thirteen indicators was or post-capillary. Nine ML models...
The characterization of perfluorsulfonate and sulfonated block copolymer ion exchange membranes is well established in aqueous systems. While many these have been proved to favorable conductivity stability multiple applications(1,2), similar studies are hardly found for non-aqueous Although some results on system published(3), a complete understanding how behave organic solvents lacking. largest range existing methods mostly dedicated probing In light emerging applications, especially...
From aqueous to non-aqueous redox flow batteries, the general membrane properties are unchanged: electronically isolating anolyte and catholyte allowing conductance through keep charge balance. However, on top of high cost(1), existing membranes for battery inherit natural disadvantage non-hydrogen-bonding transport compared all-vanadium system while leaving door wide open species pass through. Crossover-induced capacity fade remains one most challenging problems battery(2). Efforts have...
Objective To investigate the effect of hyperbaric oxygen intervention time on Glasgow Coma Score (GCS) and functional independent measure (FIM) scores in patients following traumatic brain injury, so as to provide clinical evidence for optimal comprehensive rehabilitation those patients. Methods There were 130 with moderate or severe injury (TBI), who divided according different into 4 groups: control group (n=25), HBO 1 (TBI 30 d) (n=25). The all groups received drug therapy...
Catalyst studies have improved the overall CO 2 R (electrochemical reduction) faraday efficiency (FE) 1 , however, experimental FE can be deteriorated by product crossover through membrane in a practical electrochemical cell. The molecules generated at cathode are subject to oxidation anode if they permeate membrane, thus decreasing collection. loss also poses challenge for quantification and study of behavior 2–4 . In this work, we will present designs that effectively overcome reveal...

Several studies have shown that using SnO or Bi-based catalyst, Faradaic...
As a typical single ion conductor, the perfluorsulfonate (PFSA) exchange membrane performance predominantly relies on interactions amongst cation, sulfonate group and solvent. Such solvation information is crucial to of electrochemical devices. The well-studied interaction between water proton membranes paved way for development fuel cells redox flow batteries (1–3). emerging non-aqueous battery (NARFB) features alkyl or organic cations. Given overall inferior NARFBs aqueous systems, it...
