Cobalt-nickel pertraction refinery to process pregnant leach solution from recycled spent catalysts. Part 1: Cobalt extraction from a binary system
(Taylor & Francis, 2020)
Owing to the recent increase in the global demand for Co, new cobalt–nickel refinery capacity is required. While solvent extraction is one of the most important separation and purification techniques in hydrometallurgy, ...
A NICER view of spectral and profile evolution for three x-ray-emitting millisecond pulsars
(IOP, 2020)
We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821−24, and J0218+4232. We fit Gaussians and ...
MHD-shock structures of astrospheres: λ Cephei-like astrospheres
(Oxford Univ Press, 2020)
The interpretation of recent observations of bow shocks around O-stars and the creation of corresponding models require a detailed understanding of the associated (magneto-)hydrodynamic structures. We base our study on 3D ...
New hard-TeV extreme blazars detected with the MAGIC telescopes
(IOP, 2020)
Extreme high-frequency-peaked BL Lac objects (EHBLs) are blazars that exhibit extremely energetic synchrotron emission. They also feature nonthermal gamma-ray emission whose peak lies in the very high-energy (VHE, E > 100 ...
