Simultaneous catalytic de-polymerization and hydrodeoxygenation of lignin in water/formic acid media with Rh/Al2O3, Ru/Al2O3 and Pd/Al2O3 as bifunctional catalysts
(Elsevier, 2015-04-28)
[EN] The catalytic solvolysis of 3 lignins of different sources in a formic acid/water media using bifunctional Ru/Al2O3, Rh/Al2O3, Pd/Al2O3 catalysts was explored in a batch set-up at different temperatures and reaction ...
DoE-driven development of an organocatalytic enantioselective addition of acetaldehyde to nitrostyrenes in water
(Wiley-VCH, 2022-03-01)
Moving from organic solvents to water is not always an easy task, especially when a lot of variables need to be screened. The development of an enantioselective enamine-catalysed Michael addition of acetaldehyde to ...
Synthesis of novel antiproliferative hybrid bis-(3-indolyl)methane phosphonate derivatives
(Elsevier, 2018-09-15)
An efficient synthetic methodology for the preparation of phosphorus substituted bis-(3-indolyl)methane through a double nucleophilic addition of indole derivatives to an in situ generated α-iminophosphonate is reported. ...
Representaciones sociales del Museo Guggenheim y relaciones intergrupales en la comunidad autónoma vasca: conflicto endo y exogrupal.
(Sociedad Valenciana de Psicologia Social, 2005)
Basándonos en el supuesto teórico de la existencia de una relación entre representaciones sociales e identidad social, y partiendo de la diferenciación entre elementos representacionales y valencias de dichos elementos, ...
Natural Fiber–Reinforced Cement Mortar Composite Physicomechanical Properties: From Cellulose Microfibers to Nanocellulose
(ASCE, 2023-02-28)
Using asbestos in building materials is a risk to human health, which has driven the interest in utilizing other natural fibers, such as cellulosic fibers, in cement-based building materials. There have been studies on ...

(RSC, 2022-09-27)
Mixed conducting polymer electrodes built from poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) are attracting a great deal of interest in healthcare monitoring. However, the widespread application of ...
Synthesis of novel hybrid quinolino[4,3-b][1,5]naphthyridines and quinolino[4,3-b][1,5]naphthyridin-6(5H)-one derivatives and biological evaluation as topoisomerase I inhibitors and antiproliferatives
(Elsevier, 2020-04-03)
The topoisomerase I enzymatic inhibition of hybrid quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridines and quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-ones ...
Novel phosphine sulphide gold(I) complexes: topoisomerase I inhibitors and antiproliferative agents
(RSC, 2020-05-20)
This work describes the synthesis of the gold(I) complexes of phosphine sulphides. The formation of these new derivatives has been confirmed by X-ray crystallography. The coordination of gold(I) with the sulphur atom of ...
Shock decision algorithm for use during load distributing band cardiopulmonary resuscitation
(Elsevier, 2021-08-15)
Aim
Chest compressions delivered by a load distributing band (LDB) induce artefacts in the electrocardiogram. These artefacts alter shock decisions in defibrillators. The aim of this study was to demonstrate the first ...
