A comparison of the microstructures, thermal and mechanical properties of pressed and sintered TieCu, TieNi and TieCueNi alloys intended for dental applications
(Journal of Alloys and Compounds, 2020)
The effect of Ni and Cu on the a/b phase transformation temperature, possible retention of the b-phase, and mechanical properties of Ti, Tie13Cu, Tie4.5Ni and Tie13Cue4.5Ni (compositions in wt. %) alloys were investigated. ...
Spin coating immobilisation of C-N-TiO2 Co-Doped nano catalyst on glass and application for photocatalysis or as electron transporting layer for perovskite solar cells
(MDPI, 2020)
Producingactivethinfilmscoatedonsupportsresolvesmanyissuesofpowder-basedphoto catalysis and energy harvesting. In this study, thin films of C-N-TiO2 were prepared by dynamic spin coating of C-N-TiO2 sol-gel on glass support. ...
The evolving role of science in society
(José Frantz, 2020)
The world is experiencing a traumatic change brought about by the Covid-19 pandemic. It is traumatic because it is sudden and affects everyone around the globe at once. Nothing like this has ever happened so rapidly before, ...
The lofar two-meter sky survey: Deep fields data release 1: II. The elais-n1 lofar deep field
(EDP Sciences, 2021)
The LOFAR Two-metre Sky Survey (LoTSS) will cover the full northern sky and, additionally, aims to observe the LoTSS deep fields to a noise level of ? 10 μJy beam-1 over several tens of square degrees in areas that have ...
The LOFAR Two-metre sky survey deep fields: The star-formation rate-radio luminosity relation at low frequencies
(EDP Sciences, 2021)
In this paper, we investigate the relationship between 150 MHz luminosity and the star-formation rate - the SFR-L150 MHz relation - using 150 MHz measurements for a near-infrared selected sample of 118 517 z < 1 galaxies. ...
The lofar two-meter sky survey: Deep fields data release 1: IV. Photometric redshifts and stellar masses
(EDP Sciences, 2021)
The Low Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey split across multiple tiers over the northern sky. The first LoTSS Deep Fields data release consists of deep ...
High Molecular-gas to Dust Mass Ratios Predicted in Most Quiescent Galaxies
(American Astronomical Society, 2021)
Observations of cold molecular gas reservoirs are critical for understanding the shutdown of star formation in massive galaxies. While dust continuum is an efficient and affordable tracer, this method relies upon the ...
Electrochemical studies of Pd-based anode catalysts in alkaline medium for direct glycerol fuel cells
(MDPI, 2020)
his study investigates the most effective electrocatalyst for glycerol oxidation reaction (GOR) in alkaline medium for five synthesized electrocatalysts, Pd, PdNi, PdNiO, PdMn3O4 and PdMn3O4NiO, supported on multi-walled ...
A new auroral phenomenon, the anti-black aurora
(Nature, 2021)
Black auroras are small-scale features embedded in the diffuse background aurora, typically occurring post-substorm after magnetic midnight and with an eastward drift imposed. Black auroras show a significant reduction in ...
MIGHTEE-HI: discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT
(Monthly Notices of the Royal Astronomical Society, 2021)
We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. 20
galaxies are detected in HI in this z ∼ 0.044 group, with a 3σ column density sensitivity of NHI = ...
