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 ...
A comparative study of multifunctional coatings based on electrospun fibers with incorporated ZnO nanoparticles
(MDPI, 2019)
info:eu-repo/semantics/article,
In this work, polymeric fibers of polystyrene (PS) with incorporated ZnO nanoparticles have been deposited onto an aluminum alloy substrate (6061T6) by using the electrospinning technique. In order to optimize the deposition ...
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 ...
Periodic solutions, KAM tori and bifurcations in a cosmology-inspired potential
(IOP Publishing, 2019)
Artículo / Artikulua,
A family of perturbed Hamiltonians H = 1/2 (x^2 + X^2) − 1/2 (y^2 + Y^2)+1/2
(z^2 + Z^2) + 2[ (x^4 + y^4 + z^4) + (x^2 y^2 + x^2 z^2 + y^2 z^2)] in 1: −1:1 resonance
depending on two real parameters is considered. We ...
Thermostructural behavior in a series of lanthanide-containing polyoxotungstate hybrids with copper(II) complexes of the tetraazamacrocycle cyclam: a single-crystal-to-single-crystal transformation study
(ACS Publications, 2019)
info:eu-repo/semantics/article,
A series of 14 isostructural [Cu(cyclam)](2)[{Cu(cyclam)}4{(a-GeW11O39)Ln(H2O)-(OAc)(12)].18H(2)O (1-Ln, where Ln = La Lu; cyclam = 1,4,8,11-tetraazacyclotetradecane) polyoxometalate-based hybrids reported herein represent ...
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 ...
Corrigendum to “Oscillatory motions in restricted N-body problems” [J. Differential Equations 265 (2018) 779–803]
(Elsevier, 2019)
Artículo / Artikulua,
At the beginning of paper [1] there is an error that spreads along the rest of the work and the conclusions are not correct in their present form. Precisely, in Section 2, page 783, there is a contradiction related to the ...
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 ...
