A novel treatment of biogas digestate waste for biochar production and its adsorption of methylene blue and malachite green in a binary system

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.

New Light Curves and Orbital Period Investigations of the Interacting Binary System UV Piscium

Journal of Astronomy and Space Sciences, 2019
UV Psc is a typical RS CVn type system undergoing dynamic chromosphere activity. We performed photometric observations of the system in 2015 and secured new BVR light curves showing well-defined photometric waves.

Herschel far-infrared photometry of the Swift Burst Alert Telescope active galactic nuclei sample of the local universe – III. Global star-forming properties and the lack of a connection to nuclear activity [PDF]

, 2016
We combine the Herschel Space Observatory PACS and SPIRE photometry with archival WISE photometry to construct the spectral energy distributions (SED) for over 300 local ($z 0.5$), especially at higher luminosities ($L_{14-195\,\rm{keV}} > 10^{42.5 ...

Photometric Redshifts and Photometry Errors

, 2007
We examine the impact of non-Gaussian photometry errors on photometric redshift performance. We find that they greatly increase the scatter, but this can be mitigated to some extent by incorporating the correct noise model into the photometric redshift ...

Reactivity of δ‐Functionalized para‐Quinone Methides in Nucleophilic Addition Reactions

Chemistry – A European Journal, Accepted Article.
The electrophilic reactivities of para‐quinone methides (pQMs) with functional groups at the exocyclic polarized carbon‐carbon double bond were determined by photometrical monitoring the kinetics of their reactions with carbanions in DMSO at 20°C. The experimental second‐order rate constants k2 were evaluated by the Mayr‐Patz equation, that is, the ...
