Evaluation of antimony availability in a mining context: Impact for the environment, and for mineral exploration and exploitation
(Elsevier, 2022-11-02)
This work aims to establish Sb mobility, its transfer to biota and its effect on soil health in a semi-arid climate. The results show the presence of stibnite (Sb2S3) as the main primary Sb compound, bindhemite (Pb2Sb2O6(O,OH)), ...
Fine-tune of lignin properties by its fractionation with a sequential organic solvent extraction
(Elsevier, 2022-01)
[EN] In this work, different lignins were obtained from two different extraction methods (kraft and organosolv) but from the same raw material (Eucalyptus globulus sp.). They were subsequently fractionated to determine the ...
Impact of the lignin type and source on the characteristics of physical lignin hydrogels
(Elsevier, 2022-04)
[EN] Multiple natural polymers have been investigated for the synthesis of hydrogels to the present date, but lignin has demonstrated to be a promising one for this purpose for the multiple advantages it offers. Lignin can ...
Physicochemical Characterization of Phase Change Materials for Industrial Waste Heat Recovery Applications
(MDPI, 2022-05-16)
The recovery and storage of process heat in industrial applications are some of the key factors to improve the sustainability and reliability of high temperature applications. In this sense, one of the main drawbacks is ...
Simple Coalitional Strategy Profiles in Repeated Games
(2014-10-28)
In this paper we introduce simple coalitional profi les to avoid group
deviations in repeated games. In the repeated Cournot supergame we
prove that it is possible to sustain the symmetric monopoly outcome
by means of ...
Impact of ionic quantum fluctuations on the thermodynamic stability and superconductivity of LaBH8
(APS, 2022-10-19)
The recent prediction of a metastable high-symmetry Fm-3m phase of LaBH8 gives hopes to reach high superconducting critical temperatures at affordable pressures among ternary hydrogen-rich compounds. Making use of ...
Health services research in patients with breast cancer (CAMISS-prospective): study protocol for an observational prospective study
(Biomed Central, 2019-01-08)
Background: Though breast cancer remains a major health problem, there is a lack of information on health care provided to patients with this disease and associated costs. In addition, there is a need to update and validate ...
Bayesian network-based over-sampling method (BOSME) with application to indirect cost-sensitive learning
(Nature, 2022-05)
Traditional supervised learning algorithms do not satisfactorily solve the classification problem on imbalanced data sets, since they tend to assign the majority class, to the detriment of the minority class classification. ...
Chemometrics and elemental mapping by portable LIBS to identify the impact of volcanogenic and non-volcanogenic degradation sources on the mural paintings of Pompeii
(Elsevier, 2021-05-03)
Crystallization of soluble salts is a common degradation phenomenon that threatens the mural paintings of Pompeii. There are many elements that contribute to the crystallization of salts on the walls of this archaeological ...
When Red Turns Black: Influence of the 79 AD Volcanic Eruption and Burial Environment on the Blackening/Darkening of Pompeian Cinnabar
(ACS, 2021-11-24)
It is widely known that the vivid hue of red cinnabar can darken or turn black. Many authors have studied this transformation, but only a few in the context of the archeological site of Pompeii. In this work, the co-occurrence ...
