Franck–Condon-like Progressions in Infrared Spectra of Biological Molecules

Thomas Rizzo, Michael Zachary Kamrath, Aleksandra Zabuga

Infrared spectra in the NH stretch region are often used for structure determination of gas-phase biological molecules. Vibrational couplings complicate the structure determination process by giving rise to additional vibrational bands along with the expec ...

Blends of oligopeptide terminal polyisobutylene or polystyrene

Véronique Michaud, Holger Frauenrath, Emmanuel Croisier, Su Liang

Various blends of polymers are disclosed, comprising oligopeptide functionalised polymers such as polyisobutylene and polystyrene. Mono-functionalised and di-functionalised polymers (each containing 0 to 5 peptide units beyond its terminal amide group) may ...

The role of twist and crimp on the vibration behaviour of flax fibre composites

Pierre-Etienne Bourban, Fabien Duc

The damping properties of unidirectional, 0/90 and twill 2/2 flax fibre (FF) reinforced epoxy composites containing 40 vol% of fibres have been measured by vibration beam testing (VBT). The influence of the impregnation quality, the fibre/matrix adhesion, ...

Numerical and experimental study of a nearby solid boundary and partial submergence effects on hydrofoil added mass

Mohamed Farhat, Eduard Egusquiza

The influence of the boundary conditions on the added mass of a NACA0009 cantilever hydrofoil has been numerically and experimentally investigated. The study has been focused on the effects of a lateral solid wall close to the hydrofoil tip side and of a p ...

Experimental Investigation of Pressure Fluctuations in a High-Energy Centrifugal Pump Stage at Off-Design Conditions

François Avellan, Mohamed Farhat, Stefan Berten, Philippe Dupont

In centrifugal pumps, the interaction between the rotating impeller blades and the stationary diffuser vanes generates specific pressure fluctuation patterns. At off design operation, high incidence and large local pressure gradients can lead to flow separ ...

Experimental Aeroelastic Investigation of Vibrating Turbine Blade Clusters

Peter Ott, Achim Zanker

The presented work consists of the presentation and discussion of unsteady experimental results of controlled vibration measurements for two single-blade and two cluster test cases subjected to the same subsonic flow conditions. The experiments were perfor ...

Experimental Aeroelastic Analysis of Clustered Turbine Blades Vibrating in Mixed Torsion/Bending Mode

Peter Ott, Achim Zanker

This paper presents and discusses unsteady experimental results of controlled vibration measurements of blade-cluster and single-blade test cases, all subjected to the same subsonic ow conditions. The experiments were performed in a non-rotating annular te ...

Adaptive Vibration Suppression System: An Iterative Control Law for a Piezoelectric Actuator Shunted by a Negative Capacitor

Tomas Sluka, Pavel Mokry

An adaptive system for the suppression of vibration transmission using a single piezoelectric actuator shunted by a negative capacitance circuit is presented. It is known that by using a negative-capacitance shunt, the spring constant of a piezoelectric ac ...
