Simulating key properties of lithium-ion batteries with a fault-tolerant quantum computer
(American Physical Society, 2022-09)
There is a pressing need to develop new rechargeable battery technologies that can offer higher energy storage, faster charging, and lower costs. Despite the success of existing methods for the simulation of battery ...

Environmental radioactivity and trace metals in surficial sediments from estuarine systems in Ghana (Equatorial Africa), impacted by artisanal gold-mining
(Elsevier, 2020)
This paper reports concentrations of γ-emitter radionuclides (40K, 137Cs, 210Pb, 226Ra, 228Ra, 228Th and 234Th) and some metals (Al, Cr, Fe, Co, Ni, Cu, Zn, As, Sr, Cd, Sb, Cs, Pb, Th and U) in surficial sediments from ...

Transport and dispersion of tritium from the radioactive water of the Fukushima Daiichi nuclear plant
(ELSEVIER, 2021)
Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into the Pacific Ocean. The contaminated water can poses a threat to marine ...

Cultural heritage science at CNA (seville, Spain): Applications of XRF and IBA techniques to art and archaeological objects
(Elsevier, 2020)
The use of nuclear analytical techniques has experienced an extraordinary growth in recent decades in the field of cultural heritage. Nowadays, their use in the study of objects of interest in heritage has become essential. ...

Easing COVID-19 lockdown measures while protecting the older restricts the deaths to the level of the full lockdown
(Nature Research, 2021-03)
Guided by a rigorous mathematical result, we have earlier introduced a numerical algorithm, which using as input the cumulative number of deaths caused by COVID-19, can estimate the effect of easing of the lockdown conditions. ...

Modelling the kinetic reactive transport of pollutants at the sediment-water interface. Applications with atmospheric fallout radionuclides
(Elsevier, 2022)
Understanding the behaviour of particulate matter and chemicals at the sediment-water interface (SWI) is of interest in environmental studies and risk assessments. These processes are still poorly understood, and this work ...

Revisiting multi-breathers in the discrete Klein–Gordon equation: a spatial dynamics approach
(IOP Publishing, 2022-11)
We consider the existence and spectral stability of multi-breather structures in the discrete Klein–Gordon equation, both for soft and hard symmetric potentials. To obtain analytical results, we project the system onto a ...

Highly Anisotropic Organometal Halide Perovskite Nanowalls Grown by Glancing-Angle Deposition
(Wiley, 2022-05)
Polarizers are ubiquitous components in current optoelectronic devices as displays or photographic cameras. Yet, control over light polarization is an unsolved challenge, since the main drawback of the existing display ...

Opening Fukushima floodgates: Modelling 137Cs impact in marine biota.
(ELSEVIER, 2021)
A numerical model was applied to simulate the transport of 137Cs released with the waters which were used to cool Fukushima reactors. These stored waters will be released to the Pacific Ocean according to Japanese gov ...
