Queratinas de plumaje de pollo y lana de oveja: comparativa de sus masas moleculares mediante electroforesis en gel
(Universidad de Córdoba, 2019)
Article,
El plumaje de pollo y la lana de oveja son actualmente considerados residuos agroindustriales de difícil deshecho. Es por ello que la búsqueda de aplicaciones para estos materiales es interesante desde el punto de vista ...
Comprehensive kinetics of hydrolysis of organotriethoxysilanes by 29Si NMR
(American Chemical Society, 2019)
Artículo / Artikulua,
The kinetics of several representative hybrid precursors were studied via 29Si NMR: three alkyl precursors, methyltriethoxysilane, ethyltriethoxysilane, and propyltriethoxysilane; as well as two unsaturated radicals, ...
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 ...
Effective degradation of methylene blue in aqueous solution using Pd-supported Cu-doped Ti-pillared montmorillonite catalyst
(Elsevier, 2019)
info:eu-repo/semantics/article,
The effluents from the textile, paper and food industries contain organic dyes that are strongly colored and reveal harmful effect on living systems. In order to reduce water pollution, the degradation of dye into non toxic ...
Photocatalytic degradation of trimethoprim on doped Ti-pillared montmorillonite
(Elsevier, 2019)
info:eu-repo/semantics/article,
Montmorillonite pillared with titanium and doped with Cr3+ or Fe3+ has been tested for the photo-degradation of the antibiotic trimethoprim (trimethoxybenzyl-2,4-pyrimidinediamine) under different conditions, namely, in ...
Thrust actuator with passive restoration force for wide gap magnetic bearings
(Elsevier, 2019)
info:eu-repo/semantics/article,
Active thrust magnetic bearings provide an axial force to balance the moving parts of machines. However, most devices produce null or unbalancing passive forces. Furthermore, reported designs usually feature very small ...
Effect of oxygen addition, reaction temperature and thermal treatments on syngas production from biogas combined reforming using Rh/alumina catalysts
(Elsevier, 2019)
Artículo / Artikulua,
Dry reforming and partial oxidation of biogas were studied using 0.5 wt.% Rh/Al2O3 catalysts, both inhouse prepared and commercial. The effects of O2 addition on syngas yield and biogas conversion were
studied at 700 C ...
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 ...
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 ...
