Journal ArticleDOI
Bidirectional frequency tuning of a piezoelectric energy converter based on a cantilever beam
TL;DR: In this paper, a piezoelectric energy converter is presented, whose resonance frequency can be tuned by applying mechanical stress to its structure, which consists of a piezo polymer cantilever beam with two additional thin arms, which are used to apply an axial preload to the tip of the beam.
Journal ArticleDOI
A smart and self-sufficient frequency tunable vibration energy harvester
TL;DR: In this article, the authors present a piezoelectric energy harvesting system, which is able to self-tune its resonance frequency in an energy-autonomous way, in order to extend its efficient operation over a large frequency range.
Journal ArticleDOI
Indirect Dynamics in a Highly Exoergic Substitution Reaction
Jochen Mikosch,Jiaxu Zhang,Sebastian Trippel,C Eichhorn,R. Otto,Rui Sun,Wibe A. de Jong,Matthias Weidemüller,William L. Hase,Roland Wester +9 more
TL;DR: These direct chemical dynamics simulations at the DFT/B97-1 level of theory show that the reaction is dominated by three atomic-level mechanisms, an indirect reaction proceeding via an F(-)-HCH2I hydrogen-bonded complex, a direct rebound, and a direct stripping reaction.
Journal ArticleDOI
Inverse Temperature Dependent Lifetimes of Transient SN2 Ion-Dipole Complexes
TL;DR: It is suggested that the inverse temperature dependent rates of nonsymmetric S(N)2 reactions are related to the observed inverse temperature dependence of the transient ion-dipole complexes.
Journal ArticleDOI
Kinematically complete chemical reaction dynamics

TL;DR: In this paper, the authors developed a scheme to study ion-molecule reactions by velocity map imaging at very low collision energies and compared to high-level direct dynamics trajectory calculations.
