Effect of Chemical Structure and Salt Concentration on the Crystallization and Ionic Conductivity of Aliphatic Polyethers
(MDPI, 2019-03-09)
Poly(ethylene oxide) (PEO) is the most widely used polymer in the field of solid polymer electrolytes for batteries. It is well known that the crystallinity of polymer electrolytes strongly affects the ionic conductivity ...
CO2-sourced polycarbonates as solid electrolytes for room temperature operating lithium batteries
(Royal Society of Chemistry, 2019-03-19)
In the last few years, polycarbonates have been identified as alternatives to poly(ethylene oxide) as polymer electrolytes for lithium battery applications. In this work, we show the design of CO2-sourced
polycarbonates ...
Opportunities for organocatalysis in polymer synthesis via step-growth methods
(Elservier, 2019-03-14)
Organocatalysis has emerged as an invaluable tool for polymer synthesis and has already demonstrated versatility for replacing organometallic catalysts in many polymerization reactions. The overall ease of removal and lower ...
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)
Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ...
Self-nucleation Effects on Polymer Crystallization
(ACS, 2020-05-28)
The existence of a “memory” of the previous crystalline state, which survives melting and enhances re-crystallization kinetics by a self-nucleation process, is well-known in polymer crystallization studies. Despite being ...
Melt Memory Effects in Poly(butylene succinate) Studied by Differential Fast Scanning Calorimetry
(MDPI, 2020-11-26)
It is widely accepted that melt memory effect on polymer crystallization depends on thermal history of the material, however a systematic study of the different parameters involved in the process has been neglected, so ...
Nietzsche-Wagner: el encuentro.
(Bitarte, 2010-12)
La evolución de Nietzsche y las claves de su ruptura con Wagner.
Bancos, bibliotecas y cementerios: usos de las analogías y las clasificaciones en el razonamiento sobre biotecnología
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2011)
[ES] El uso de analogías en bioética es muy frecuente. Dado que son instrumentos especialmente eficaces desde un punto de vista retórico, resulta fundamental determinar bajo qué condiciones la formulación de analogías ...
Chemosensory response of marine flagellate towards L- and D- dissolved free amino acids generated during heavy grazing on bacteria
(Spanish Society for Microbiology, 2010-09)
This study investigated the generation of dissolved free amino acids (DFAA) by the bacterivorous flagellate Rhynchomonas nasuta when feeding on abundant prey. Specifically, it examined whether this flagellate protist ...
River doctors: Learning from medicine to improve ecosystem management
(Elsevier, 2017-10-01)
Effective ecosystem management requires a robust methodology to analyse, remedy and avoid ecosystem damage. Here we propose that the overall conceptual framework and approaches developed over millennia in medical science ...
