Isolation of the elusive heptavanadate anion with trisalkoxide ligands
(ACS, 2021)
Artículo / Artikulua,
The unprecedented heptavanadate cluster has been isolated from reactions between trisalkoxide ligands and vanadatein water at pH = 2 as a series of alkylammonium [HxV7O18(H2O)((OCH2)3CR)](4−x)‑salts (1−3,R=CH2OH;4,R=CH3). ...
Life cycle assessment of power-to-methane systems with CO2 supplied by the chemical looping combustion of biomass
(Elsevier, 2022)
Artículo / Artikulua,
Power-to-methane (PtM) systems may allow fluctuations in the renewable energy supply to be smoothed out by storing surplus energy in the form of methane. These systems work by combining the hydrogen produced by electrolysis ...
Icephobic and anticorrosion coatings deposited by electrospinning on aluminum alloys for aerospace applications
(MDPI, 2021)
info:eu-repo/semantics/article,
Anti-icing or passive strategies have undergone a remarkable growth in importance as a complement for the de-icing approaches or active methods. As a result, many efforts for developing icephobic surfaces have been mostly ...
Analysis and application of an overlapped FEM-BEM for wave propagation in unbounded and heterogeneous media
(Elsevier, 2022)
info:eu-repo/semantics/article,
An overlapped continuous model framework, for the Helmholtz wave propagation problem in unbounded regions comprising bounded heterogeneous media, was recently introduced and analyzed by the authors (2020) [10]. The continuous ...
Optical system based on multiplexed FBGs to monitor hand movements
(IEEE, 2021)
info:eu-repo/semantics/article,
This contribution reports the development and characterization of an optical system based on parallel Fiber Bragg Gratings (FBGs) to monitor the movements of the wrist and fingers of a hand. The system consisted of a ...
Tryptophan levels as a marker of auxins and nitric oxide signaling
(MDPI, 2022)
info:eu-repo/semantics/article,
The aromatic amino acid tryptophan is the main precursor for indole-3-acetic acid (IAA),
which involves various parallel routes in plants, with indole-3-acetaldoxime (IAOx) being one of
the most common intermediates. ...
Application of a modeling tool to describe fly ash generation, composition, and melting behavior in a wheat straw fired commercial power plant
(MDPI, 2020)
info:eu-repo/semantics/article,
Ash behavior is a key operational aspect of industrial-scale power generation by means of biomass combustion. In this work, FactSage™ 6.4 software was used to develop and assess three models of wheat straw combustion in a ...
Comparative study of tribomechanical properties of HiPIMS with positive pulses DLC coatings on different tools steels
(MDPI, 2021)
info:eu-repo/semantics/article,
Diamond-like carbon (DLC) coatings are very interesting due to their extraordinary properties; their excellent wear resistance, very low friction coefficient, great hardness, high elastic modulus or biocompatibility can ...
On certain subspaces of p for 0 < p ≤ 1 and their applications to conditional quasi-greedy bases in p-Banach spaces
(Springer, 2021)
info:eu-repo/semantics/article,
We construct for each 0<p≤1 an infinite collection of subspaces of ℓp that extend the example of Lindenstrauss (Bull. Acad. Polon. Sci. Sér. Sci. Math. Astronom. Phys. 12, 539–542, 1964) of a subspace of ℓ1 with no ...
Multigrid solvers for multipoint flux approximations of the Darcy problem on rough quadrilateral grids
(Springer, 2020)
info:eu-repo/semantics/article,
In this work, an efficient blackbox-type multigrid method is proposed for solving multipoint flux approximations of the Darcy problem on logically rectangular grids. The approach is based on a cell-centered multigrid ...
