Segmental Dynamics Govern the Cold Crystallization of Poly(lactic acid) in Nanoporous Alumina
Shi, Guangyu; Guan, Yu; Liu, Guoming; Müller Sánchez, Alejandro Jesús 
; Wang, Dujin (ACS Publications, 2019-09-04)
; Wang, Dujin (ACS Publications, 2019-09-04)
How segmental mobility influences the crystallization behavior of polymers in confined spaces is still not fully understood. In the present work, a systematic study of the segmental dynamics was carried out by dielectric ...
Confined Crystallization of Polymers within Nanopores
; Müller Sánchez, Alejandro Jesús ; (ACS, 2021-08-03)
; (ACS, 2021-08-03)
Crystallization of polymeric materials under nanoscopic confinement is highly relevant for nanotechnology applications. When a polymer is confined within rigid nanoporous anodic aluminum oxide (AAO) templates, the ...
Crystallization Kinetics and Nanoparticle Ordering in Semicrystalline Polymer Nanocomposites
; ; ; ; ; ; Müller Sánchez, Alejandro Jesús ; (Elsevier, 2022-03-13)
; (Elsevier, 2022-03-13)
There has been considerable interest in the nucleation and crystallization of polymers in the presence of nanoparticles (NPs, or nanofillers in general, NFs). Most of the extensive work in this area has focused on anisotropic, ...
Effect of Nanoconfinement on the isodimorphic crystallization of Poly(butylene succinate-ran-caprolactone) Random Copolymers
Safari, Maryam; Leon Boigues, Laia; Shi, Guangyu; Maiz, Jon; Liu, Guoming; Wang, Dujin; Mijangos, Carmen; Müller Sánchez, Alejandro Jesús (ACS, 2020-07-21)
(ACS, 2020-07-21)
In this paper, we study for the first time the effect of hard confinement on the isodimorphic crystallization of random copolyesters. A series of poly(butylene succinate-ran-caprolactone) samples encompassing the entire ...
Direct Relationship between Dispersion and Crystallization Behavior in Poly(ethylene oxide)/Poly(ethylene glycol)-g-Silica Nanocomposites
Wen, Xiangning; Su, Yunlan; Liu, Guoming; Li, Shaofan; Müller Sánchez, Alejandro Jesús ; Kumar, Sanat K.; Wang, Dujin (American Chemical Society, 2021-02-08)
; Kumar, Sanat K.; Wang, Dujin (American Chemical Society, 2021-02-08)
The inclusion of polymer-grafted nanoparticles (PGNPs) can impart various
functional properties to polymer nanocomposites (PNCs). For semicrystalline
polymers, we can control the spatial dispersion of PGNPs and presumably ...
Impact of MOF-5 on pyrrolidinium-based poly(ionic liquid)/ionic liquid membranes for biogas upgrading
(ACS, 2019-12-03)
Bearing in mind that Metal Organic Frameworks (MOFs) have remarkable CO2 adsorption selectivity and Mixed Matrix Membranes (MMMs) have been identified as potential solution for advancing the current state of the art of ...
Even-odd Effect in Aliphatic Polycarbonates with Different Chain Lengths: from Poly (hexamethylene carbonate) to Poly (dodecamethylene carbonate)
Pérez Camargo, Ricardo Arpad; Meabe Iturbe, Leire; ; Liu, Guoming; Zhao, Ying; Wang, Dujin; Müller Sánchez, Alejandro Jesús (ACS, 2020-12-17)
(ACS, 2020-12-17)
We have characterized a series of aliphatic polycarbonates synthesized by organocatalysis containing a variable number of methylene groups (nCH2) in their repeat units ranging from nCH2 = 6 to 12. The melting and crystallization ...
Toward Supramolecular Nanozymes for the Photocatalytic Activation of Pt(IV) Anticancer Prodrugs
Mazzei, Laura Filomena; Martínez, Álvaro; Trevisan, Lucia; Rosa Gastaldo, Daniele; López Cortajarena, Aitziber ; Mancin, Fabrizio; Salassa, Luca (Royal Society Of Chemistry, 2020-09-16)
; Mancin, Fabrizio; Salassa, Luca (Royal Society Of Chemistry, 2020-09-16)
A supramolecular nanozyme for the photocatalytic conversion of a Pt(IV) anticancer complex to cisplatin is described herein. We employed 1.9 nm Au nanoparticles decorated with thiol ligands bearing a TACN (1,4,7-triazacyclononane) ...
Residual alignment and its effect on weld strength in material-extrusion 3D-printing of polylactic acid
; ; ; ; Müller Sánchez, Alejandro Jesús ; ; ; (Elsevier B.V, 2020-06-30)
; ; ; (Elsevier B.V, 2020-06-30)
Gaining a molecular understanding of material extrusion (MatEx) 3D printing is crucial to predicting and
controlling part properties. Here we report the direct observation of distinct birefringence localised to the ...
Janus 3D Printed Dynamic Scaffolds for Nanovibration-Driven Bone Regeneration
(Nature, 2021-02-15)
The application of physical stimuli to cell cultures has shown potential to modulate multiple cellular functions including migration, differentiation and survival. However, the relevance of these invitro models to future ...
