; (ACS, 2018-07-17)
A complete study of the effect of different organocatalysts on the step-growth polyaddition of a five-membered dicyclic carbonate, namely diglycerol dicarbonate, with a poly(ethylene glycol)-based diamine in bulk at 120 ... -
Unexpected trends in halogen-bond based noncovalent adducts
(RSC, 2012-06-14)Unexpected trends in the strengths of halogen-bond based adducts of CY3I (Y = F, Cl, Br, I) with two typical Lewis bases (chloride and trimethylamine) show that the halogen-bond donor strength (Lewis acidity) of a compound ... -
Uniaxial and Mixed Orientations of Poly(ethylene oxide) in Nanoporous Alumina Studied by X-ray Pole Figure Analysis
Su, Cui; Shi, Guangyu; Li, Xiaolu; Zhang, Xiuqin; Müller Sánchez, Alejandro Jesús; Wang, Dujin; Liu, Guoming (American Chemical Society, 2018-11-16)
The orientation of polymers under confinement is a basic, yet not fully understood phenomenon. In this work, the texture of poly(ethylene oxide) (PEO) infiltrated in nanoporous anodic alumina oxide (AAO) templates was ... -

Unions as ‘managers of precariousness’: The entrenchment of micro-corporatism in the Spanish automotive industry and its drawbacks
(Emerald, 2018-07-06)This paper enriches and updates the literature on micro-corporatism, collective bargaining in transnational corporations, and the erosion of trade union power resources which dates back to the 1990s and early 2000s. Whilst ... -
La unión europea en las negociaciones climáticas: ¿Referente o líder en la lucha contra el calentamiento global?
García Lupiola, Asier (Tirant lo Blanch, 2022-10)
La UE lleva décadas en primera línea de la lucha contra el cambio climático y constituye un referente en esta materia, tanto por las políticas y normas adoptadas a nivel interno como por las propuestas presentadas en las ... -
Uniqueness for solutions of the Schrödinger equation on trees
Fernández Bertolin, Aingeru; Jaming, Philippe (Fondazione Annali di Matematica Pura ed Applicata and Springer Nature, 2019-08-30)
We prove that if a solution of the time-dependent Schrödinger equation on an homogeneous tree with bounded potential decays fast at two distinct times then the solution is trivial. For the free Schrödinger operator, we use ... -

Universal class of type-IIB flux vacua with analytic mass spectrum
; Sousa, Kepa; Álvarez Urquiola, Mikel ; (American Physical Society, 2021-05)
We report on a new class of flux vacua generically present in Calabi-Yau compactifications of type-IIB string theory. At these vacua, the mass spectrum of the complete axiodilaton/complex structure sector is given, to ... -
Universal Scaling Law for the Size Effect on Superelasticity at the Nanoscale Promotes the Use of Shape‐Memory Alloys in Stretchable Devices
Fuster, Valeria; ; Nó Sánchez, María Luisa; San Juan Núñez, José María (Wiley, 2020-02)
Shape-memory alloys (SMAs) are the most stretchable metallic materials thanks to their superelastic behavior associated with the stress-induced martensitic transformation. This property makes SMAs of potential interest for ... -
