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 = ...
Reflectivity of VUV-sensitive silicon photomultipliers in liquid Xenon
(IOP Publishing, 2021)
Silicon photomultipliers are regarded as a very promising technology for nextgeneration,
cutting-edge detectors for low-background experiments in particle physics. This work
presents systematic reflectivity studies of ...
Effects of alkali and transition metal-doped TiO2 hole blocking layers on the perovskite solar cells obtained by a two-step sequential deposition method in air and under vacuum
(Royal Society of Chemistry, 2020)
Planar perovskite solar cells (PPSCs) have received great attention in recent years due to their intriguing properties, which make them a good choice for photovoltaic applications. In this work, the effect of alkali and ...
Observing relativistic features in large-scale structure surveys - I. Multipoles of the power spectrum
(Oxford University Press, 2021)
Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation and the possibility of constraining novel ...
Mixed-halide perovskites solar cells through PbICl and PbCl2 precursor films by sequential chemical vapor deposition
(Elsevier, 2021)
Mixed halide perovskites with chlorine (Cl) content have received significant interest due to better charge transport properties and longer diffusion length compared to pure iodine-based perovskites. The superior properties ...
Extremely deep 150 MHz source counts from the LoTSS deep fields
(EDP Sciences, 2021)
With the advent of new generation low-frequency telescopes, such as the LOw Frequency ARray (LOFAR), and improved calibration techniques, we have now started to unveil the subgigahertz radio sky with unprecedented depth ...
The impact of solar wind variability on pulsar timing
(EDP Sciences, 2021)
Context. High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are variable in time. In a previous paper, ...
