Multivariate analysis of pharmaceutical pollutants adsorption in aqueous media with tailored waste-based carbonaceous adsorbent materials and commercial activated carbons
(Elsevier, 2024-04)
Article
Accés obertThe purpose of this research is to determine the effectiveness of various biocollagenic waste-based activated carbons (BWAC) and a sludge biochar (SBC) in removing emerging pharmaceutical pollutants (phenol, salicylic acid, ... -
Carbon footprint evaluation in tunnels excavated in rock using tunnel boring machine (TBM)
(Springer, 2024-01-30)
Article
Accés obertThe generation of CO2 is an important element in assessing the environmental impact generated in a tunnel construction project, making this knowledge very useful for evaluating different alternatives. In this study, an ... -
Machine learning assisted multifrequency AFM: Force model prediction
(American Institute of Physics (AIP), 2023-12-05)
Article
Accés obertMultifrequency atomic force microscopy (AFM) enhances resolving power, provides extra contrast channels, and is equipped with a formalism to quantify material properties pixel by pixel. On the other hand, multifrequency ... -
Metodologías IA en la detección de infiltraciones en presas
(2023-12-20)
Article
Accés obertHistóricamente, una de las causas más comunes de rotura de las presas, se debe a vertido por coronación, principalmente en presas de materiales sueltos. Existen otros causantes en la rotura de presas de mampostería como ... -
Architecting an open-source IIoT framework for real-time control and monitoring in the bioleaching industry
(Multidisciplinary Digital Publishing Institute, 2023-12-29)
Article
Accés obertElectronic waste (e-waste) contains toxic elements causing an important impact on environmental and human health. However, the presence of valuable metals, such as copper or gold, among others, make recycling a necessity ... -
Differentiation between copal and amber by their structure and thermal behaviour
(Springer, 2023-12)
Article
Accés obertThe relationships between the polymerization related to structure and the composition of different types of natural resins were determined. Analyses were carried out by Fourier transform infrared spectroscopy (FTIR), ... -
Super-regenerative receiver wake-up radio solution for 5G New Radio communications
(2023-12-14)
Article
Accés obertWake-up radio is a promising solution to reduce the energy wasted by mobile devices during an idle state. In this paper, we propose a new wake-up radio solution for 5G mobile devices based on a super-regenerative receiver ... -
Microflow injection analysis based on modular 3D platforms and colorimetric detection for Fe(III) monitoring in a wide concentration range
(Springer Nature, 2023-12-02)
Article
Accés obertA modular microflow injection analysis (microFIA) system for the determination of Fe(III) in a bioleaching reactor has been designed, developed and validated. The different modules of the analyzer (mixer, diluter, disperser ... -
Empirical correlation for in-situ deformation modulus of sedimentary rock slope mass and support system recommendation using the Qslope method
(Techno press, 2023-12-10)
Article
Accés restringit per política de l'editorialThis article is dedicated to the pursuit of establishing a robust empirical relationship that allows for the estimation of in-situ modulus of deformations (Em and Gm) within sedimentary rock slope masses through the ... -
Metallogenic model of the Eocene Santa María and Antares Zn-Pb(-Ag) skarn deposits, Velardeña Mining District, Durango, Mexico
(Springer Nature, 2023-11-03)
Article
Accés obertThe Santa María and Antares Zn-Pb(-Ag) skarn deposits in the Velardeña Mining District are located in central–NW Mexico. They lie 470 m apart along the contact between Oligocene felsic intrusions and Cretaceous limestones, ... -
Viability of bauxite deposits from Catalonia (Spain) for ceramic applications
(2023-10-04)
Article
Accés obertThis study provides a characterization of materials from wastes and outcrops of two inactive bauxite mines located close to Sant Joan de Mediona and Peramola, Spain. Mineralogy was determined via powder X-ray diffraction ... -
A high productivity bioprocess for obtaining metallic copper from printed circuit boards (PCBs)
(2024-01-01)
Article
Accés restringit per política de l'editorialPCBs constitute a residue rich in metals, among which copper stands out due to its majority content, much higher than that found in natural deposits, so that it is a potential secondary resource. Many attempts have been ...
