Structural characterization, optical properties and photocatalytic activity of MOF-5 and its hydrolysis products: implications on their excitation mechanism
(Royal Society of Chemistry, 2015-08-21)
The existing concerns on the limited stability of Zn4O-based MOFs upon exposure to humidity or aqueous environments, as well as on the excitation mechanisms, are discussed on the basis of Raman, FTIR, DR-UV and XRD ...
Influence of Excitation Signal on Impedance-based Structural Health Monitoring
(Sage Publications Ltd, 2010-09-01)
The electromechanical impedance (EMI) technique has been successfully used in structural health monitoring (SHM) systems on a wide variety of structures. The basic concept of this technique is to monitor the structural ...
Quantum mechanical modeling of excited electronic states and their relationship to cathodoluminescence of BaZrO3
(2013-07-28)
First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** ...

Influence of ideal and non-ideal excitation sources on the dynamics of a nonlinear vibro-impact system
(Polish Soc Theoretical & Applied Mechanics, 2013-01-01)
The objective of the present work is to analyze the dynamics of a vibro-impact system consisting of two blocks of different mass coupled by a spring with two stages. Two different types of excitation sources for the system ...
State-selective Rydberg excitation with femtosecond pulses
(American Physical Society, 2013-04)
We show that multipulse excitation of Rydberg atoms with a sequence of short time-delayed femtosecond pulses results in strong n selection of the final-state amplitudes. In the experiment, a 150 fs laser pulse, which alone ...
On numerical simulations of a nonlinear self-excited system with two non-ideal sources
(2005-12-01)
In this work, the dynamic behavior of self-synchronization and synchronization through mechanical interactions between the nonlinear self-excited oscillating system and two non-ideal sources are examined by numerical ...

Harvesting Energy from Time-Limited Harmonic Vibrations: Mechanical Considerations
(2017-10-01)
Single-degree-of-freedom (SDOF) mechanical oscillators have been the most common type of generators used to harvest energy from mechanical vibrations. When the excitation is harmonic, optimal performance is achieved when ...
