Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly

Advanced Science, EarlyView.
In this study, hydrophobic tripeptides are explored as building blocks for stable piezoelectric crystals. Tripeptides with phenylalanine at the central position self‐assembled into uniform, thermally stable crystals. Piezoresponse force microscopy reveals a high effective piezoelectric coefficient of 24.0 pC N−1, attributed to asymmetric molecular ...

Self-Excited Vibrations in Drillstrings

SPE Annual Technical Conference and Exhibition, 1987
Abstract Vibrations created by drag bits can cause premature failure of drillstring components and fracture cutters. Unfortunately, there has been no theory that adequately explains how drag bits excite drillstrings. Our paper shows that these vibrations are self excited by the interaction of drillstring, bit, and formation. Results show

Ship Propulsion Self-Excited Torsional Vibration

Volume 4: Cycle Innovations; Fans and Blowers; Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Marine; Oil and Gas Applications, 2011
Self-excited vibration is demonstrated in many common day events, for example, wheel-castor shimmy or a traffic sign twisting in a steady strong wind [1]. Another example, blade flutter, is well known in the gas turbine community. The affected system will typically oscillate at its natural frequency.
