A layered titanosilicate AM-4 as a novel catalyst for the synthesis of 1-methoxy-2-propanole from propylene oxide and methanol
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper we report for the first time the catalytic properties of the titanosilicate AM-4 in the synthesis of 1-methoxy-2-propanol (PGME) from methanol and propylene oxide (PO). PGME is widely used as a pollution-free ...
Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure
(Springer, 2019)
info:eu-repo/semantics/article,
Outliers and missing data are commonly found in satellite imagery. These are usually caused by atmospheric or electronic failures, hampering the correct monitoring of remote-sensing data. To avoid distorted data, we propose ...
Adsorption recovery of Ag(I) and Au(III) from an electronics industry wastewater on a clay mineral composite
(University of Science and Technology BeijingSpringer, 2019)
info:eu-repo/semantics/article,
The aim of this work is to investigate the ability of an adsorbent of a clay mineral composite to remove and recover gold and silver ions from wastewater. The composite was prepared by mixing phosphogypsum (PG), obtained ...
Negative reflection, negative refraction and ray displacements in biaxial absorbing media, In4Se3
(Taylor & Francis, 2019)
info:eu-repo/semantics/article,
We show the existence of negative reflection and negative refraction in a slab of biaxial absorbing medium In 4Se3 placed between two isotropic media. We find the limiting angle of incidence in the slab for these phenomena ...
Magnetocaloric effect enhancement driven by intrinsic defects in a Ni45Co5Mn35Sn15 alloy
(Elsevier, 2019)
info:eu-repo/semantics/article,
The influence of mechanically-induced defects on the magnetostructural properties is analyzed in a Ni-Co-Mn-Sn alloy subjected to soft milling and subsequent annealing treatments. It is found that, opposite to what occurs ...
Pretreatment and enzymatic hydrolysis for the efficient production of glucose and furfural from wheat straw, pine and poplar chips
(Elsevier, 2019)
info:eu-repo/semantics/article,
A flexible approach to a two-step biorefinery for the production of glucose and furfural from three different feedstocks is presented. Pretreatment conditions were selected to drive the production towards the generation ...
Online relative risks/rates estimation in spatial and spatio-temporal disease mapping
(Elsevier, 2019)
info:eu-repo/semantics/article,
Background and objective: Spatial and spatio-temporal analyses of count data are crucial in epidemiology and other fields to unveil spatial and spatio-temporal patterns of incidence and/or mortality risks. However, fitting ...
Outstanding role of the magnetic entropy in arrested austenite in an ordered Ni45Mn36.7In13.3Co5 metamagnetic shape memory alloy
(Elsevier, 2019)
info:eu-repo/semantics/article,
The relevance of the entropy and in particular the outstanding role of the magnetic contribution is analyzed in a non-equilibrium arrested austenite phase in a Ni 45 Mn 36.7 In 13.3 Co 5 metamagnetic shape memory alloy. ...
Enantioselective addition of alkynyl ketones to nitroolefins assisted by Brønsted base/H-bonding catalysis
(Wiley, 2019)
info:eu-repo/semantics/article,
Various sets of enolizable alkynyl ketones (including methyl ynones with α-aryl, α-alkenyl, and α-alkoxy groups) were able to react smoothly with nitroolefins with the assistance of bifunctional Brønsted base/H-bond catalysts ...
Asymptotic greediness of the Haar system in the spaces Lp[0 , 1] , 1< p< ∞
(Springer, 2019)
info:eu-repo/semantics/article,
Our aim in this paper is to attain a sharp asymptotic estimate for the greedy constant Cg[H(p), Lp] of the (normalized) Haar system H(p) in Lp[0 , 1] for 1 < p < ∞. We will show that the super-democracy constant of H(p) ...
