Engineering patterns of wrinkles and bubbles in supported graphene through modeling and simulation
(Universitat Politècnica de Catalunya, 2015-06-10)
Tesi
Accés obertGraphene deposited on a substrate often exhibits out-of-plane deformations with different features and origins. Networks of localized wrinkles have been observed in graphene synthesized through CVD, as a result of compressive ... -
Engineering photoresponse in epitaxial BiFe0.5Cr0.5O3 thin films through structural distortion
(American Chemical Society (ACS), 2022-08-16)
Article
Accés obertMultiferroic BiFe0.5Cr0.5O3 (BFCO) thin films are promising candidates for emerging optoelectronics and all-oxide solar absorbers. Yet, a thorough understanding of the structural evolution and associated changes in the ... -
Engineering polymers with improved charge transport properties from bithiophene-containing polyamides
(Royal Society of Chemistry (RSC), 2020)
Article
Accés obertPolymer semiconductors show unique combinations of mechanical and optoelectronic properties that strongly depend on their microstructure and morphology. Here, we have used a model p-conjugated bithiophene repeat unit to ... -
Engineering redox active sites enriched 3D-on-2D bimetallic double layered hydroxide electrode for supercapatteries
(2022-10)
Article
Accés restringit per política de l'editorialThe functionalization of structural nanoengineered battery-type electrodes has aided the emergence of supercapattery (SCp) subclass, which enables a wide range of applications. Herein, our research work provides a platform ... -
Engineering schools facing the thorny issue of training students in collaborative skills: feedback from the field
(Universitat Politècnica de Catalunya, 2022-09)
Text en actes de congrés
Accés obertIn a context of transformation and increasing complexity of work due to the development of information technologies, communication and digital networks, the question of the acquisition and development of collaborative ... -
Engineering self-organized criticality in living cells
(2021-12-01)
Article
Accés obertComplex dynamical fluctuations, from intracellular noise, brain dynamics or computer traffic display bursting dynamics consistent with a critical state between order and disorder. Living close to the critical point has ... -
Engineering sleep disorders : from classical CPAP devices toward new intelligent adaptive ventilatory therapy
(2014-09-01)
Article
Accés restringit per política de l'editorialAmong the most common sleep disorders are those related to disruptions in airflow (apnea) or reductions in the breath amplitude (hypopnea) with or without obstruction of the upper airway (UA). One of the most important ... -
Engineering social reality with inheritance relations
(Springer, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialIn systems based on organisational specifications a reoccurring problem remains to be solved in the disparity between the level of abstractness of the organisational concepts and the concepts used in the implementation. ... -
Engineering soliton nonlinearities: from local to strongly nonlocal
(2009-01)
Article
Accés restringit per política de l'editorialWe put forward what we believe to be a novel strategy to achieve synthetic nonlinearities where local and nonlocal contributions compete on a similar footing, thus yielding intermediate tunable responses ranging from local ... -
