Bright fireballs recorded along February 2021 in the framework of the Southwestern Europe Meteor Network
(MeteorNews, 2021)
Artículo / Artikulua,
This work focuses on the analysis of some of the brightest bolides recorded along February 2021 by the meteorobserving stations operating in the framework of the Southwestern Europe Meteor Network (SWEMN). Some of them ...
Locally adaptive change-point detection (LACPD) with applications to environmental changes
(Springer, 2021)
Artículo / Artikulua,
We propose an adaptive-sliding-window approach (LACPD) for the problem of change-point detection in a set of time-ordered observations. The proposed method is combined with sub-sampling techniques to compensate for the ...
Hybrid xerogels: study of the sol-gel process and local structure by vibrational spectroscopy
(MDPI, 2021)
info:eu-repo/semantics/article,
The properties of hybrid silica xerogels obtained by the sol-gel method are highly dependent on the precursor and the synthesis conditions. This study examines the influence of organic substituents of the precursor on the ...
Feasibility to producing second generation bioethanol in Bolivia
(Universidad Nacional del Sur (Argentina), 2021)
info:eu-repo/semantics/article,
Bioethanol produced worldwide is mostly obtained from agricultural crops such as sugarcane and corn. However, it has negative environmental effects, so opportunity for producing bioethanol from agricultural waste arises. ...
Improved adhesion of the DCL coating using HiPIMS with positive pulses and plasma immersion pretreatment
(MDPI, 2021)
info:eu-repo/semantics/article,
Diamond-like carbon (DLC) coatings are used due to their extraordinary tribomechanical properties, great hardness, high elastic modulus, high wear resistance, low friction coefficient and chemical inertness, which provide ...
Strain sensing based on resonant states in 2D dielectric photonic quasicrystals
(Optica, 2021)
Artículo / Artikulua,
This paper reports the numerical and experimental study of the strain sensing effect of bidimensional quasiperiodic structures made with dielectric cylinders. Structures of around 100 cylinders arranged following a Penrose ...
Understanding the formation of Al13 and Al30 polycations to the development of microporous materials based on Al13-and Al30-PILC montmorillonites: a review
(Elsevier, 2021)
Artículo / Artikulua,
Hydrolysis of aluminum cations (Al3+), the third most abundant metal in the Earth’s crust, is considered relevant
in many academic fields, including materials science and chemical engineering. AlIII -polycations and ...
Polioxometalatoak ingurune urtsuan: egitura esanguratsuenak
(Universidad de País Vasco, 2021)
Artículo / Artikulua,
Polioxometalatoen (POMen) konposizio eta egitura aniztasun ikaragarria, ur disoluzioan aurkezten dituzten oreka kimiko dinamikoen emaitza dira. Izan ere, beraien eraketa prozesuak ingurune azidotan gertatzen diren oxoanioien ...
