Impact of Planar and Vertical Organic Field‐Effect Transistors on Flexible Electronics
No full text: The development of flexible and conformable devices, whose performance can be maintained while being continuously deformed, provides a significant step towards the realization of next-generation wearable and e-textiles applications. Organic field-effect transistors (OFETs) are particularly interesting for flexible and lightweight products, because of their low-temperature solution processability, and the mechanical flexibility of organic materials that endows OFETs the natural compatibility with plastic and biodegradable substrates. Here, an in-depth review of two competing flexible OFET technologies, planar and vertical OFETs (POFETs and VOFETs, respectively) is provided. The electrical, mechanical, and physical properties of POFETs and VOFETs are critically discussed, with a focus on four pivotal applications (integrated logic circuits, light-emitting devices, memories, and sensors). It is pointed out that the flexible function of the relatively newer VOFET technology, along with its perspective on advancing the applicability of flexible POFETs, has not been reviewed so far, and the direct comparison regarding the performance of POFET- and VOFET-based flexible applications is most likely absent. With discussions spanning printed and wearable electronics, materials science, biotechnology, and environmental monitoring, this contribution is a clear stimulus to researchers working in these fields to engage towards the plentiful possibilities that POFETs and VOFETs offer to flexible electronics.

Advanced Neuromorphic Applications Enabled by Synaptic Ion-Gating Vertical Transistors
No full textAbstract Bioinspired synaptic devices have shown great potential in artificial intelligence and neuromorphic electronics. Low energy consumption, multi‐modal sensing and recording, and multifunctional integration are critical aspects limiting their applications. Recently, a new synaptic device architecture, the ion‐gating vertical transistor (IGVT), has been successfully realized and timely applied to perform brain‐like perception, such as artificial vision, touch, taste, and hearing. In this short time, IGVTs have already achieved faster data processing speeds and more promising memory capabilities than many conventional neuromorphic devices, even while operating at lower voltages and consuming less power. This work focuses on the cutting‐edge progress of IGVT technology, from outstanding fabrication strategies to the design and realization of low‐voltage multi‐sensing IGVTs for artificial‐synapse applications. The fundamental concepts of artificial synaptic IGVTs, such as signal processing, transduction, plasticity, and multi‐stimulus perception are discussed comprehensively. The contribution draws special attention to the development and optimization of multi‐modal flexible sensor technologies and presents a roadmap for future high‐end theoretical and experimental advancements in neuromorphic research that are mostly achievable by the synaptic IGVTs

Amending the European Insolvency Regulation to Strengthen Main Proceedings
No full textThe EC Regulation No 1346 on insolvency proceedings allows for the coexistence of different proceedings with respect to the same debtor. This triggers certain problems in terms of efficiency of the insolvency administration within the European Judicial Space, thus menacing the effet utile of the Regulation.
The article focuses on such problems, explaining the shortcomings which affect the Regulation and wondering whether the ECJ case-law managed a solution for them.
As a matter of principle, preventing the opening of secondary proceedings seems in several cases to be a suitable means for protecting the main proceedings’ purposes. However, at the same time, not opening secondary proceedings could hamper the interests of local creditors, which rely on it to safeguard their rights on the grounds of the local lex concursus. The author addresses the main aspects of this tension.
The Regulation is under revision as result of a Proposal of the European Commission, which, inter alia, aims to strike a balance between the aforesaid interests at odds. The author, hence, carries out a critical appraisal of the envisaged amendments having also regard to the recent reactions of the other European Institutions
Improvement of poly(3-hexylthiophene-2,5-diyl) electron mobility through complete elimination of regioregularity defects
No full textThe improvement of electron transport in polymer semiconductors is highly desirable for realizing robust, large-area and low-cost organic integrated circuits. This work investigates the effect of regioregularity on the intrinsic hole and electron transport characteristics of poly(3-hexylthiophene-2,5-diyl) (P3HT) using current-voltage (I-V) measurements in metal/polymer/metal sandwich structures. Through a direct comparison between 93% regioregular P3HT (EG-P3HT) and 100% regioregular defect-free poly(3-hexylthiophene-2,5-diyl) (DF-P3HT), it is found that the elimination of regioregularity defects improves the electron mobility of DF-P3HT (1.05 × 10-7 cm2 V-1 s-1) by three orders of magnitude compared to the 93% regioregular EG-P3HT sample (1.82 × 10-10 cm2 V-1 s-1). Quantum chemical calculations indicate that the improvement of electron mobility in DF-P3HT can be associated to the lower degree of disorder in these samples that tends to increase the transfer angle between the lowest unoccupied molecular orbitals of adjacent chains. At the same time, the lower dipole moments produced by the defect-free polymer molecules also appears to play an important role in decreasing the susceptibility of charge transport to environment-induced electron traps. The obtained results provide a strong evidence that the elimination of regioregularity defects is an effective technique to improve electron transport and restore the symmetry between hole and electron mobility in P3HT as well as other thiophene-based polymers
Towards a New Interface BetweenBrussels I and Arbitration?
No full textArbitral tribunals and state courts are currently called upon to coexist in the European
Judicial Space without being clearly coordinated with each other. The author wonders
whether Regulation (EU) No 1215/2012, irrespective of restating the arbitration exclusion,
brings a novelty in this regard by way of Recital 12—which sets out the arbitration
exclusion’s scope—and Article 73(2)—which safeguards the 1958 New York
Convention. Certain well known issues concerning the interface between Brussels I
and arbitration—such as the risk of conflicting decisions either on the merits or on the
arbitration agreement, the defence against derailing or delaying tactics flouting an arbitration
agreement, the enforcement of anti-suit injunctions or judgments awarding
damages for breach of the obligation to arbitrate—have been reviewed so as to appreciate
whether and to what extent things have really changed
Leandro y Hero : de la Edad Media al Renacimiento europeo
No full textEste trabajo pretende ampliar la investigación de la Fábula de Leandro y Hero de Juan Boscán a partir del estudio de obras de distintas épocas que relatan la misma historia. En el artículo se desvelan posibles fuentes que sirvieron al autor barcelonés para la composición de su fábula con la finalidad de reconstruir su origen. La aparición de unos mismos motivos y episodios en obras tan alejadas en el tiempo permite especular con la posibilidad de la existencia de una fuente común que haya servido de modelo a todas ellas. Por otro lado, en este trabajo también se estudia la influencia que ejerció la fábula de Boscán en la literatura posterior del Siglo de Oro.This work tries to extend the investigation about Fábula de Leandro y Hero by Juan Boscán by the study of some literary works of different times that relate the same history. In this paper are revealed other possible sources that helped the author to write his fable in order to rebuild its origin. The development of the same motifs and chapters in remotes works allows us to gamble on the existence of a common source that would serve as a model for all of them. In addition, in this work is studied the influence that involve Boscan's fable in the subsequent literacy of the Spanish Golden Age
