Gravitational bouncing of a quantum ball: Room for Airy's function Bi
(2002)"I apply (i) a classical version of the Ermakov-Lewis procedure and (ii) the strictly isospectral supersymmetric approach to the Schrodinger free fall of the bouncing ball type. In both cases, the Airy function Bi, which ... -
Growth of Ni nanoclusters on irradiated graphene: A molecular dynamics study
(Royal Society of Chemistry, 2018)"We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ... -
Growth of Trichoderma atroviride and importance of the nano-motor Kinesin-1 in its development
(2019-02)"The vegetative growth of filamentous fungi comprises cell elongation and branching. This complex process involves Intracellular transport of molecules, vesicles and organelles within the cell interior, assisted by motor ... -
H2Ti3O7 nanotubes decorated with silver nanoparticles for photocatalytic degradation of atenolol
(Hindawi Publishing Corporation, 2017)"The photocatalytic degradation/adsorption process of the β-blocker atenolol (ATL) under UV irradiation is described using two types of silver decorated catalysts: silver/titania and silver/titanates. The silver ions were ... -
Happy and agreeable?: multi-label classification of impressions in social video
(ACM, 2015)"The mobile and ubiquitous nature of conversational social video has placed video blogs among the most popular forms of online video. For this reason, there has been an increasing interest in conducting studies of human ... -
Heterojunction of CuO nanoclusters with TiO2 for photo-oxidation of organic compounds and for hydrogen production
(American Institute of Physics, 2020)"Heterojunctions of small CuO nanoclusters (synthesized by radiolysis) with TiO2 (commercial P25) induced a photocatalytic activity under visible light irradiation in a wide range of wavelengths due to the narrow bandgap ... -
Hierarchy in 1D carbon nanostructures: from theoretical design and properties calculation to experimental synthesis and characterization.
(2008)"A key challenge in nanotechnology is the assembly of nanostructured components (building blocks; such as DNA molecules, 0D clusters and 1D nanowires) into well ordered arrays. Based on this research trend, the core proposal ... -
High temperature martensitic transformation and giant magnetocaloric effect in Ni40Co10Mn41Sn9 melt-spun ribbons
(Elsevier, 2018)"We report a large magnetic entropy change associated with a high-temperature martensitic transformation in Ni40Co10Mn41Sn9 (at. %) melt-spun ribbons. The ribbons underwent a first-order forward martensitic transition and ... -
High-gain nonlinear observer for simple genetic regulation process
(Elsevier, 2007)"High-gain nonlinear observers occur in the nonlinear automatic control theory and are in standard usage in chemical engineering processes. We apply such a type of analysis in the context of a very simple one-gene reg-ulation ... -
High-magnetic field characterization of magnetocaloric effect in FeZrB(Cu) amorphous ribbons
(2015-05)"The magnetic and magnetocaloric properties of a series of Fe-rich FeZrB(Cu) amorphous ribbons were investigated under magnetic field values up to mu H-0 of 8 T. A correlation between the saturation magnetization and the ... -
