Experimental post-selection loophole-free time-bin and energy-time nonlocality with integrated photonics
(Optica Publishing Group, 2024-04-20)
Time-bin (TB) and energy-time (ET) entanglements are crucial resources for long-distance quantum information processing. However, their standard implementations suffer from the so-called post-selection loophole that allows ...

Oleo-dispersions of electrospun cellulose acetate butyrate nanostructures: toward renewable semisolid lubricants
(Wiley, 2024)
In this work, the electrospinnability of cellulose acetate butyrate (CAb)solutions, and the ability of the resulting micro- and nano-architectures tostructure castor oil are studied aiming to develop eco-friendly ...

Impact of vegetable oil type on the rheological and tribological behavior of Montmorillonite-based oleogels
(MDPI, 2022-08-13)
We formulated and characterized oleogels based on montmorillonite clay and vegetable oils that could serve as eco-friendly semi-solid lubricants. In particular, we studied the influence of the physical-chemical properties ...

Transfer of 129I to freshwater fish species within Fukushima and Chernobyl exclusion zones
(Elsevier, 2023)
Unique data is reported on the transfer of 129I iodine from freshwaters to fish as well as the internal distribution within fish from the Fukushima and Chernobyl exclusion zones (ChEZ). Samples of water, sediments and ...

The cumulative effect of three decades of phosphogypsum amendments in reclaimed marsh soils from SW Spain: 226Ra, 238U and Cd contents in soils and tomato fruit
(Elsevier, 2008)
Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW Spain, where available PG has a typical ...

The use of 137-cs in marine and lacustrine sediment dating
(Pergamon Press, 1992)
En este trabajo, la técnica de datación 137 Cs con precisión mejorada se muestra como una herramienta poderosa para establecer cronologías en diferentes depósitos acuáticos jóvenes (lacustres, marinos). El método tiene ...

A self-sufficient and general method for self-absorption correction in gamma-ray spectrometry using GEANT4
(Elsevier, 2007)
This paper presents a self-sufficient and general method for measurement of the activity of low-level gamma-emitters in voluminous samples by gamma-ray spectrometry with a coaxial germanium detector. Due to self-absorption ...

Radiometrical and physico-chemical characterisation of contaminated glass waste from a glass dump in Sweden
(Elsevier, 2020-02)
Around former glass factories in south eastern Sweden, there are dozens of dumps whose radioactivity and physico-chemical properties were not investigated previously. Thus, radiometric and physico-chemical characteristics ...

Certifying sets of quantum observables with any full-rank state
(American Physical Society, 2024-04-03)
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these two properties make it possible to certify ...

Machine learning techniques for the ab initio Bravais lattice determination
(Wiley, 2023-02)
Machine learning-based algorithms have been widely applied recently in different areas due to its ability to solve problems in all fields. In this research, machine learning techniques classifying the Bravais lattices from ...
