A study on the feasibility of a battery-based electric propulsion system for ONAerospace eVTOL
(Universitat Politècnica de Catalunya, 2023-02-15)
Treball Final de Grau
Accés obert
Realitzat a/amb: ONAerospaceThe purpose of this project is to perform a study on the current and near-future feasibility of a battery system for commercial and regional aviation. Analysing the energy requirements of the ONA eVTOL and the different ... -
Black silicon solar cells with interdigitated back-contacts achieve 22.1% efficiency
(2015-05-18)
Article
Accés obertThe nanostructuring of silicon surfaces—known as black silicon—is a promising approach to eliminate front-surface reflection in photovoltaic devices without the need for a conventional antireflection coating. This might ... -

Improved thermal isolation of silicon suspended platforms for an all-silicon thermoelectric microgenerator based on large scale integration of Si nanowires as thermoelectric material
(2015-12-10)
Article
Accés obertSpecial suspended micro-platforms have been designed as a part of silicon compatible planar thermoelectric microgenerators. Bottom-up grown silicon nanowires are going to bridge in the future such platforms to the surrounding ... -
Influence of growth parameters on the optical properties of ZnO nanowires
(Universitat Politècnica de Catalunya, 2010-09-10)
Projecte Final de Màster Oficial
Accés obertZnO nanowires are source of a great interest in the scientific community due to numerous properties and the wide range of possible applications of this nanoscale material. Influence of the ZnO NWs growth parameters such ... -
Observation of the topological Anderson insulator in disordered atomic wires
(2018-11-23)
Article
Accés obertTopology and disorder have a rich combined influence on quantum transport. In order to probe their interplay, we synthesized one-dimensional chiral symmetric wires with controllable disorder via spectroscopic Hamiltonian ... -
Optical characterization of molecular beam epitaxy grown GaAs nanotrees
(Universitat Politècnica de Catalunya, 2018-07)
Treball Final de Grau
Accés obertIn the aim to grow vertical self-catalyzed GaAs nanowires on [100] Si, fancy structures with a tapered shape resembling a tree were observed. They were called nanotrees. This is the first time that vertical growth has been ... -
Single-crystalline metal oxide, resistive gas sensors advances and perspectives
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialHere we review recent results on the synthesis of single-crystalline metal oxide nanomaterials and their integration in resistive gas sensing devices. Emphasis is put on the integration of such nanomaterials in a wide ... -
Sonochemical synthesis and stabilization of concentrated antimicrobial silver-chitosan nanoparticle dispersions
(Wiley, 2017-08)
Article
Accés obertThis work reports on a green synthetic route to produce concentrated aqueous dispersions of silver nanoparticles (AgNP) employing high-intensity ultrasound (US) and chitosan (CS) as a non-toxic reducing agent for Ag1 salts ... -
Visible photoluminescence components of solution-grown ZnO nanowires: Influence of the surface depletion layer
(2012-09-13)
Article
Accés obertArrays of electrodeposited ZnO nanowires (NWs) were used to illustrate the dependence of the ZnO visible photoluminescence (PL) emission on the extension of the surface depletion layer and obtain further insight into the ...
