Role of Vibrational Dynamics in Electronic Relaxation of Cr(acac)3
2015
Ultrafast energy relaxation of Cr(acac)3 dissolved in tetrachloroethylene (TCE) is studied by time-resolved infrared (TRIR) spectroscopy by using electronic and vibrational excitation. After electronic excitation at 400 or 345 nm, the ground state recovers in two time scales: 15 ps (major pathway) and 800 ps (minor pathway), corresponding to fast electronic transition to the ground state and intermediate trapping on the long-lived (2)E state followed by intersystem crossing (ISC) to the ground state. The quantum yield for the fast recovery of the ground state depends on the excitation wavelength, being higher for 345 nm. Vibrational cooling (VC) occurs on the electronic excited states with …
Music, vibrotactile mediation and bodily sensations in anorexia nervosa : "It's like I can really feel my heart beating"
2020
This article presents the theoretical, scientific, and methodological foundations for the design and implementation of an innovative technological and clinical platform that combined sound, music, and vibrotactile mediation used in a therapeutic setting by adolescents suffering from anorexia nervosa. In 2019, we carried out a pilot experiment with a group of 8 adolescent patients hospitalized in the Eating Disorders Unit of the Department of Adolescent and Young Adult Psychiatry of the Institut Mutualiste Montsouris in Paris. Within this clinical framework, we aimed to create conditions suitable for patients to reinvest in their “disaffected” bodily zones and internal experiences through re…
On the Dynamics of Fractional Visco-Elastic Beams
2012
With increasing advanced manufacturing process, visco-elastic materials are very attractive for mitigation of vibrations, provided that you may have advanced studies for capturing the realistic behavior of such materials. Experimental verification of the visco-elastic behavior is limited to some well-known low order models as the Maxwell or Kelvin models. However, both models are not sufficient to model the visco-elastic behavior of real materials, since only the Maxwell type can capture the relaxation tests and the Kelvin the creep tests, respectively. Very recently, it has been stressed that the most suitable model for capturing the visco-elastic behavior is the spring-pot, characterized …
