Efficient recovery of aluminum from saline slag wastes
(Elsevier, 2019)
info:eu-repo/semantics/article,
This work presents the procedure to improve the aluminum extracted from a hazardous waste from the recycling of aluminum, aluminum that could be used in the production of value-added materials, as well as with the generation ...
Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential
(Springer, 2019)
Artículo / Artikulua,
We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon–
Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced
system with at most four non degenerate ...
IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots
(Elsevier, 2019)
Artículo / Artikulua,
Indole-3-acetaldoxime (IAOx) is a particularly relevant molecule as an intermediate in the pathway for tryptophan-dependent auxin biosynthesis. The role of IAOx in growth-signalling and root phenotype is poorly studied in ...
Phenyl siloxane hybrid xerogels: structure and porous texture
(Springer US, 2019)
Artículo / Artikulua,
The aim of this research is to investigate the effect of phenyltriethoxysilane (PhTEOS) and
tetraethoxysilane (TEOS) molar ratios as silicon precursors on the structure and porous texture of xerogels.
We have prepared ...
Identification of a Ni-vacancy defect in Ni-Mn-Z (Z = Ga, Sn, In): an experimental and DFT positron-annihilation study
(American Physical Society, 2019)
Artículo / Artikulua,
By means of experimental positron-annihilation-lifetime measurements and theoretical density functional
theory (DFT) positron-lifetime calculations, vacancy-type defects in Ni50Mn50−xSnx (x = 25, 20, 15, 13, 10) and ...
Self-referenced optical fiber sensor for hydrogen peroxide detection based on LSPR of metallic nanoparticles in layer-by-layer films
(MDPI, 2019)
info:eu-repo/semantics/article,
Intensity-based optical fiber sensors are one of the most studied sensor approaches thanks to their simplicity and low cost. Nevertheless, their main issue is their lack of robustness since any light source fluctuation, ...
Tough and functional cross-linked bioplastics from sheep wool keratin
(Nature Research, 2019)
info:eu-repo/semantics/article,
Novel bioplastic flms derived from wool keratins were prepared by protein solution in an alkaline mild oxidative method that splits disulphide (-S-S-) bonds. The native structure of the keratin macromolecules was partially ...
Impact of extraction conditions on the phenolic composition and antioxidant capacity of grape stem extracts
(MDPI, 2019)
info:eu-repo/semantics/article,
The use of grape stems for the extraction of bioactive compounds to be used in the pharmaceutical, food, and cosmetic industries is a promising objective. The aim of this work is to determine the influence of the different ...
Layer-by-layer nano-assembly: a powerful tool for optical fiber sensing applications
(MDPI, 2019)
info:eu-repo/semantics/article,
The ability to tune the composition of nanostructured thin films is a hot topic for the design of functional coatings with advanced properties for sensing applications. The control of the structure at the nanoscale level ...
White and red Brazilian Sao Simao's kaolinite-TiO2 nanocomposites as catalysts for toluene photodegradation from aqueous solutions
(MDPI, 2019)
info:eu-repo/semantics/article,
The presence of volatile organic compounds in groundwater is a major concern when it is used as a drinking water source because many of these compounds can adversely affect human health. This work reports on the preparation ...
