Highly Efficient Utilization of Ferrate(VI) Oxidation Capacity Initiated by Mn(II) for Contaminant Oxidation: Role of Manganese Species.

Environmental Science and Technology, 2023
Manganese ion [Mn(II)] is a background constituent existing in natural waters. Herein, it was found that only 59% of bisphenol A (BPA), 47% of bisphenol F (BPF), 65% of acetaminophen (AAP), and 49% of 4-tert-butylphenol (4-tBP) were oxidized by 20 μM of ...

Iron(III)-(1,10-Phenanthroline) Complex Can Enhance Ferrate(VI) and Ferrate(V) Oxidation of Organic Contaminants via Mediating Electron Transfer.

Environmental Science and Technology, 2023
Recent research has primarily focused on the utilization of reductants as activators for Fe(VI) to generate high-valent iron species (Fe(IV)/Fe(V)) for the degradation of emerging organic contaminants (EOCs).

Population improvement in pyrethrum (Chrysanthemum cinerariaefolium Vis.)

Euphytica, 1985
A population improvement programme in pyrethrum had progressively increased the mean pyrethrins content from 1.33 percent in the unselected base population to 1.97 percent in the population developed after one cycle of each of mass and recurrent selections.

Improved performance of certain II–VI phosphors

Journal of Luminescence, 1988
Abstract Sunstone-IR and Sunstone-FL, proprietary II–VI phosphors, demonstrate superior fluorescent, phosphorescent and IR up-conversion properties. These characteristics are important for IR sensors, optical data storage, digital radiography and other applications.

Improved cosmogenic Ne measurements using ThermoFisher ARGUS VI

2022
<p>Cosmogenic Ne is used to record timing and rates of surface processes on the Earth and Moon and the time of meteorite release from parent bodies. Precise determination of neon isotopes in rocks and minerals has improved in the last ten years largely as a consequence of developments in mass spectrometry and associated electronics.& ...

Predicting Viscosity-Shear Relationships of VI Improved Lubricants

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">The majority of crankcase lubricants are now formulated to contain polymeric additives to improve the viscosity temperature properties to provide a better lubricating film in the various bearing systems in an internal combustion engine. These VI (viscosity index) improved lubricants are non-Newtonian under the high

Mono- and bimetallic nanoparticles decorated KTaO3 photocatalysts with improved Vis and UV-Vis light activity

Applied Surface Science, 2018
Novel mono- and bimetallic nanoparticles (MNPs and BNPs) decorated surface of perovskite-type KTaO3 photocatalysts were successfully synthesized by hydrothermal reaction of KTaO3 followed by photodeposition of MNPs/BNPs. The effect of noble metal type (MNPs = Au, Ag, Pt, Pd, Rh, Ru or BNPs = Au/Pt, Ag/Pd, Rh/Ru), amount of metal precursor (0.5, 1.0, 1 ...
