Whispering Gallery Modes: Advanced Photonic Applications

2019

Los micro-resonadores basados en Whispering Gallery Modes (WGMs) han atraido un gran interés en las últimas décadas debido a su fuerte confinamiento de la luz. Tales micro-resonadores pueden ser fabricados con diferentes geometrías y materiales. Estos micro-resonadores exhiben factores de calidad Q altos y volúmenes modales pequeños, lo que permite realizar un gran número de estudios y aplicaciones, como por ejemplo el estudio de efectos no-lineales ópticos. La delgada anchura spectral que presentan las resonancias WGM permite la medida de pequeñas perturbaciones de los parámetros de los micro-resonadores, con un límite de detección bajo. Esta tesis proporciona la caracterización experiment…

The Instability of Ni{N(SiMe3)2}2: A Fifty Year Old Transition Metal Silylamide Mystery

2015

The characterization of the unstable NiII bis(silylamide) Ni{N(SiMe3)2}2 (1), its THF complex Ni{N(SiMe3)2}2(THF) (2), and the stable bis(pyridine) derivative trans-Ni{N(SiMe3)2}2(py)2 (3), is described. Both 1 and 2 decompose at ca. 25 °C to a tetrameric NiI species, [Ni{N(SiMe3)2}]4 (4), also obtainable from LiN(SiMe3)2 and NiCl2(DME). Experimental and computational data indicate that the instability of 1 is likely due to ease of reduction of NiII to NiI and the stabilization of 4 through dispersion forces. peerReviewed

Molecular dynamics simulations of heavy ion induced defects in SiC Schottky diodes

2018

Heavy ion irradiation increases the leakage current in reverse-biased SiC Schottky diodes. This letter demonstrates, via molecular dynamics simulations, that a combination of bias and ion-deposited energy is required to produce the degradation. Peer reviewed

Failure Load and Collapse Mode of an RC Beam in a Large Collapsed Roof

2021

The present work focused on the determination of the collapse load and of the failure mode of a collapsed framed structure constructed in the South of Italy and failed in 2004 under its self-weight. Information available was the results on extensive experimental test campaign, for the determination of mechanical properties of concrete and steel bars of beams, floors and columns involved in the failure. Moreover, draws of original design with construction details and design rules valid in Italy at the time of construction were found. A simple monodimensional beam model for prediction of load-deflection curve, able to include degradation of constituent materials (concrete, steel and bond) was…

Interactive effects of state anxiety and trait anxiety on emotional Stroop interference

2001

This study examined main, interaction, and quadratic effects of state and trait anxiety on attentional bias toward threat related stimuli. Students (n=121) completed a card version of an emotional Stroop task. While there were no main effects for trait anxiety or state anxiety, regression analyses revealed a significant contribution of the interaction term of both variables. Only for individuals high in trait anxiety, was state anxiety positively related to Stroop interference. In contrast, the low anxious group showed the opposite response pattern. A quadratic effect of trait anxiety was also found but the interaction term proved to be the most important predictor. Implications of these fi…

The Role of e-Tutor Competencies in Postgraduate e-Learning Courses: Spotlight on Emotion Management

2021

The role of e-learning in the existing and challenging educational era is crucial. However, it is necessary to overcome some drawbacks such as feelings of isolation and a lack of emotional contact. In this sense, emotion management is a key driver of student satisfaction in e-learning, which is significantly related to students’ motivation, learning, cognitive strategies, self-regulation, and personality antecedents in the classroom. This article examines an online postgraduate course in financial statements auditing, describing the resources used by the e-tutor to conduct affective tutorials, reduce students’ feelings of isolation, increase student involvement, and achieve success in e-lea…
