Effect of the TrFE Content on the Crystallization and SSA Thermal Fractionation of P(VDF-co-TrFE) Copolymers
(MDPI, 2022-09-08)
In this contribution, we study the effect of trifluoro ethylene (TrFE) comonomer content (samples with 80/20, 75/25, and 70/30 VDF/TrFE molar ratios were used) on the crystallization in P(VDF-co-TrFE) in comparison with a ...
Pi-magnetism and quantum transport in graphene-based nanostructures
(2022-10-21)
El grafeno constituye un material idóneo para aplicaciones electrónicas, sin embargo, al no poseer un gapen la estructura de bandas, este material dos-dimensional no puede utilizarse para construir la arquitecturadel ...
Characterization and Modification of Red Mud and Ferrosilicomanganese Fines and Their Application in the Synthesis of Hybrid Hydrogels
(MDPI, 2022-10-14)
In this work, hybrid hydrogels were synthesized with the inclusion of two types of clay materials that are considered industrial waste: red mud (RM) and ferrosilicomanganese fines (FeSiMn). These solid waste materials were ...
Unraveling the effects of Fe and Mn promoters on the tungstated zirconia catalyst: A DFT study
(Elsevier, 2022-10)
Periodic DFT calculations are performed to unravel the effect of the incorporation of Fe and Mn into the tung-stated zirconia catalyst, (WO3)x/ZrO2 (x = 1,3), in their electronic, geometric, and catalytic properties. Our ...
Ionic Liquid-Cured Epoxy/PCL Blends with Improved Toughness and Adhesive Properties
(MDPI, 2022)
In this work, ionic liquid (IL)-cured epoxy resins were modified by adding poly(ε-caprolactone) (PCL). Three different ILs were used in order to study how (a) the chemical structure of the ILs and (b) the PCL content affect ...
Structure and Properties of Reactively Extruded Opaque Post-Consumer Recycled PET
(MDPI, 2021-10-14)
The recyclability of opaque PET, which contains TiO2 nanoparticles, has not been as well-studied as that of transparent PET. The objective of this work is to recycle post-consumer opaque PET through reactive extrusion with ...
Printability Study of a Conductive Polyaniline/Acrylic Formulation for 3D Printing
(MDPI, 2021-06-23)
There is need for developing novel conductive polymers for Digital Light Processing (DLP) 3D printing. In this work, photorheology, in combination with Jacobs working curves, efficaciously predict the printability of ...
Spin excitations of individual magnetic dopants in an ionic thin film
(IOP, 2022-10)
Individual magnetic transition metal dopants in a solid host usually exhibit relatively small spin excitation energies of a few meV. Using scanning tunneling microscopy and inelastic electron tunneling spectroscopy (IETS) ...
Attaining Toughness and Reduced Electrical Percolation Thresholds in Bio-Based PA410 by Combined Addition of Bio-Based Thermoplastic Elastomers and CNTs
(MDPI, 2021-09-05)
Multi-walled carbon nanotubes (CNTs) were added to provide electrical conductivity to bio-based polymer blends with improved toughness (based on commercially available Pebax thermoplastic elastomers and bio-based polyamide ...
Synthesis, Structure, Crystallization and Mechanical Properties of Isodimorphic PBS-ran-PCL Copolyesters
(MDPI, 2021-07-09)
Isodimorphic behavior is determined by partial inclusion of comonomer segments within the crystalline structure and arises from the comparatively similar repeating chain units of the parental homopolymers. Isodimorphic ...
