Angular momentum problem The angular momentum problem is a problem in astrophysics identified by Leon Mestel in 1965. It was found that the angular momentum of a protoplanetary disk is misappropriated when compared to models during stellar birth. The Sun and other stars are predicted by models to be rotating considerab... | https://en.wikipedia.org/wiki?curid=38367028 |
Biotransducer Electrochemical biosensors contain a biorecognition element that selectively reacts with the target analyte and produces an electrical signal that is proportional to the analyte concentration. In general, there are several approaches that can be used to detect electrochemical changes during a biorecogniti... | https://en.wikipedia.org/wiki?curid=38380954 |
Biotransducer The reference electrode provides a constant half-cell potential that is unaffected by analyte concentration. A high impedance voltmeter is used to measure the electromotive force or potential between the two electrodes when zero or no significant current flows between them. The potentiometric response is ... | https://en.wikipedia.org/wiki?curid=38380954 |
Biotransducer The reaction between the biomolecule and analyte changes the ionic species concentration, leading to a change in the solution electrical conductivity or current flow. Two metal electrodes are separated at a certain distance and an AC potential is applied across the electrodes, causing a current flow betwe... | https://en.wikipedia.org/wiki?curid=38380954 |
Biotransducer Devices based on field-effect transistors (FETs) have attracted great attention because they can directly translate the interactions between target biological molecules and the FET surface into readable electrical signals. In a FET, current flows along the channel which is connected to the source and the ... | https://en.wikipedia.org/wiki?curid=38380954 |
Biotransducer Acoustic waves can be projected to the thin film to produce an oscillatory device, which then follows an equation that is nearly identical to the Sauerbrey equation used in the QCM method. Biomolecules, such as proteins or antibodies can bind and its change in mass gives a measureable signal proportional ... | https://en.wikipedia.org/wiki?curid=38380954 |
Turnip crinkle virus (TCV) hairpin H4 In molecular biology, is an RNA hairpin found at the 3' end of the Turnip crinkle virus (TCV) genome.
