ABSTRACT Background and Purpose. White matter hyperintensities (WMHs) are bright objects observed in the white on brain magnetic resonance (MR) imaging. WMHs often reported as “normal” findings but may represent pathological changes. The prevalence of appears to increase with increasing age although both typical timing clinical significance their appearance among medically neurologically healthy persons remains unclear. We assessed a cohort younger subjects. Methods . Our study comprised 243...
Heterogeneous catalysts are desired for the conversion of glucose, most abundant sugar in renewable biomass, but presently their synthesis requires highly toxic chemicals with long times. We report glucose into fructose and 5-hydroxymethylfurfural on a heterogeneous catalyst that is stable selective operates environmentally benign solvent, water. used bifunctional solid Lewis Brønsted acid sites by partially replacing organic linker zirconium framework UiO-66...
Understanding the formulation and manufacturing parameters that lead to higher energy density longevity is critical designing energy-dense graphite electrodes for battery applications. A limited dataset includes 27 different formulation, protocols, performance properties reported. Input from are varied: slurry composition, mixing protocol, electrode coating gap size, drying temperature, speed, calendering. Measurable outputs rheological characteristics, adhesion, electrochemical testing...
The metal–organic framework MIL-101(Cr) is known as a solid–acid catalyst for the solution conversion of biomass-derived glucose to 5-hydroxymethyl furfural (5-HMF). We study substitution Cr3+ by Fe3+ and Sc3+ in MIL-101 structure order prepare more environmentally benign catalysts. MIL-101(Fe) can be prepared, inclusion Sc possible at low levels (10% Fe replaced). On extended synthesis times polymorphic MIL-88B instead forms.Increasing amount also only yields MIL-88B, even short...
Herein, Zeolitic imidazolate framework-8 (ZIF-8) is considered as an easy and cheap to prepare alternative catalyst for the isomerization of glucose production 5-hydroxymethyl furfural (HMF). For synthesis ZIF-8 catalysts two preparation methods were evaluated, being room temperature hydrothermal at 140 °C. Of these, method yields a material with exceptionally high surface area (1967 m2·g−1). As catalyst, materials generated excellent fructose yields. Specifically, prepared by yielded...
Abstract Metal organic framework UiO‐66 is studied as an adaptable heterogeneous catalyst for glucose conversion. was modified by; i) partial linker substitution, ii) particle size modulation and iii) defects. We the effect of crystallinity functional groups on conversion product yields. The main products are: fructose from isomerisation glucose, mannose epimerisation 5‐hydroxymethyl furfural dehydration fructose. found that defective nano crystalline performs best isomerisation. When 50 %...
Abstract As electric vehicles become more widely used, there is a higher demand for lithium‐ion batteries (LIBs) and hence greater incentive to find better ways recycle these at their end‐of‐life (EOL). This work focuses on the process of reclamation re‐use cathode material from LIBs. Black mass containing mixed LiMn 2 O 4 Ni 0.8 Co 0.15 Al 0.05 Nissan Leaf pouch cell are recovered via two different recycling routes, shredding or disassembly. The waste stream purity compared both processes,...
Nickel‐rich layered oxide cathodes, such as LiNi 0.9 Mn 0.05 Co O 2 (NMC 90‐5‐5) exhibit high energy densities but face challenges related to capacity fade and structural instability that arise during the material synthesis procedure. This study explores their shorter firing times lower temperatures via large‐scale hydroxide precipitation boron‐based fluxes sintering. After optimisation, critical insight into effect of fluxes, on electrochemical properties NMC 90‐5‐5 are investigated. Boric...
The high-Mr alkali-stable form of cathepsin B was purified from purulent human sputum. It shown to solubilize proteoglycan monomer entrapped in polyacrylamide at a rate comparable with that lysosomal B. Like the enzyme lysosomes, sputum bound by alpha 2-macroglobulin, which inhibited its action on proteoglycan. Cystatin C be N-terminally truncated generated neutrophil elastase cleavage, and only weakly recombinant cystatin had been cleaved vitro. Addition mucoid led 5-fold increase activity...
Yb6(BDC)7(OH)4(H2O)4 contains both bridging hydroxyls and metal-coordinated waters, possessing Brønsted Lewis acid sites. The material crystallises from water at 200 °C. Using the solid as a heterogenous catalyst, glucose is converted into 5-hydroxymethylfurfural, via fructose, with total selectivity of ∼70% after 24 hours 140 °C in alone: recyclable no loss crystallinity.
The rutiles (M,Ru)O2 (M = Mg, Zn, Co, Ni, Cu) are formed directly under hydrothermal conditions at 240 °C from potassium perruthenate and either peroxides of zinc or magnesium poorly crystalline oxides cobalt, nickel, copper. polycrystalline powders consist lath-shaped crystallites, tens nanometres in maximum dimension. Powder neutron diffraction shows that the materials have an expanded a axis contracted c compared to parent RuO2, but there is no evidence lowering symmetry other AO2-type...
The prevalence of chronic hepatitis C virus (HCV) infection among incarcerated individuals in the United States is estimated to be between 12% and 31%. HCV treatment during incarceration an attractive option because improved access health care directly observed therapy. We compared nonincarcerated HCV-infected patients evaluated for at a single academic center January 1, 2002 December 31, 2007. During this period, 521 388 were treatment. Three hundred nineteen (61.2%) 234 (60.3%) underwent...
AbstractSputum samples from 25 patients with bronchiectasis were assayed enzymatically for myeloperoxidase, neutrophil elastase and cathepsin B, immunologically cystatin A, C, S kininogen. High myeloperoxidase levels found in those sputum that assessed visually to be purulent. These also contain high of B activity but low the most effective inhibitor, C. In contrast, activities had C levels. It is concluded positively correlated degree inflammation recruitment. Although this may due part...
Electrocatalytic water splitting using iridate pyrochlores studied synchrotron spectroscopy reveals a response from all iridium in the conducting oxide.
Iridate pyrochlores formed by hydrothermal synthesis provide robust OER catalysts for membrane electrode assemblies, giving effective oxygen evolution with minimal carbon corrosion.
Iridium-containing NaTaO3 is produced using a one-step hydrothermal crystallisation from Ta2O5 and IrCl3 in an aqueous solution of 10 M NaOH 40 vol% H2O2 heated at 240 °C. Although nominal replacement 50% Ta by Ir was attempted, the amount included perovskite oxide only up to 15 mol%. The materials are formed as crystalline powders comprising cube-shaped crystallites around 100 nm edge length, seen scanning transmission electron microscopy. Energy dispersive X-ray mapping shows even...
