Nanostructural Organization of Thin Films Prepared by Sequential Dip-Coating Deposition of Poly(Butylene Succinate), Poly(ε-Caprolactone) and Their Copolyesters (PBS-ran-PCL)
(Elsevier, 2021-06-04)
In this work, we prepare and characterize multiphasic thin films containing poly(epsilon-caprolactone), PCL, poly (butylene succinate), PBS, and a poly (butylene succinate-ran-epsilon-caprolactone) (PBS-ran-PCL) random ...
Kinetics of NH3 Desorption and Diffusion on Pt: Implications for the Ostwald Process.
(American Chemical Society, 2021-10-21)
We report accurate time-resolved measurements of NH3 desorption from Pt(111) and Pt(332) and use these results to determine elementary rate constants for desorption from steps, from (111) terrace sites and for diffusion ...
Influence of Calcium Ion-Modified Implant Surfaces in Protein Adsorption and Implant Integration
(Springer, 2021-04-21)
Background Calcium (Ca) is a well-known element in bone metabolism and blood coagulation. Here, we investigate the link between the protein adsorption pattern and the in vivo responses of surfaces modified with calcium ...
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 ...
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 ...
Protein adsorption/desorption dynamics on Ca-enriched titanium surfaces: biological implications
(Springer, 2021-08-27)
Calcium ions are used in the development of biomaterials for the promotion of coagulation, bone regeneration, and implant osseointegration. Upon implantation, the time-dependent release of calcium ions from titanium implant ...
Length Absence of Spillover of Hydrogen Adsorbed on Small Palladium Clusters Anchored to Graphene Vacancies
(Elsevier, 2021-08-01)
Experimental evidence exists for the enhancement of the hydrogen storage capacity of porous carbons when these materials are doped with metal nanoparticles. One of the most studied dopants is palladium. Dissociation of the ...
Recyclable Epoxy Resin via Simultaneous Dual Permanent/Reversible Crosslinking Based on Diels-Alder Chemistry
(Wiley, 2021-09)
Taking advantage of the reversible Diels-Alder (DA) reaction, a simple strategy to obtain recyclable epoxy resins is presented. For this purpose, blends of furan-functionalized and nonfunctionalized epoxy resin are prepared. ...
