Many spacecraft propulsion methods such as ion thrusters require an input of electric power to run but are highly efficient.

This procedure is also highly efficient for the introduction of foreign genes in tissue culture cells, especially mammalian cells.

In highly symmetrical molecules the crystal phase is densely packed with many efficient intermolecular interactions resulting in a higher enthalpy change on melting.

However, neither Johnson nor Stevenson was a match for the talented and highly efficient Kennedy campaign team led by Robert F. Kennedy.

Gamma cameras and other similar detectors are highly efficient, and the tracer compounds are generally very effective at concentrating at the areas of interest, so the total amounts of radioactive material needed are very small.

Layer 2 switching is highly efficient because there is no modification to the data packet, only to the frame encapsulation of the packet, and only when the data packet is passing through dissimilar media ( such as from Ethernet to FDDI ).

A key feature of the evaporation or field ion images is that the data density is highly inhomogeneous, due to the corrugation of the specimen surface at the atomic scale.

The high ionic radius of the Pb < sup > 2 +</ sup > ion renders it highly immobile in the matrix and hinders the movement of other ions ; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass ( 10 < sup > 8. 5 </ sup > vs 10 < sup > 6. 5 </ sup > Ohm · cm, DC at 250 ° C ).

Ions in crystal lattices of purely ionic compounds are spherical ; however, if the positive ion is small and / or highly charged, it will distort the electron cloud of the negative ion, an effect summarised in Fajans ' rules.

This effect is called ion channelling, and, like all the channelling effects, is highly nonlinear, with small variations from perfect orientation resulting in extreme differences in implantation depth.

For this reason, molecules and molecular ions which are unstable on Earth can be highly abundant in space, for example the H < sub > 3 </ sub >< sup >+</ sup > ion.

Magnesium is a relatively abundant ion in the lithosphere and is highly bioavailable in the hydrosphere.

The break observed in the charge distribution may perhaps mean that the shift from the Dole to the ion evaporation mechanism arises at m � 104, though this inference is highly hypothetical.

Cellular respiration ( both aerobic and anaerobic ) utilizes highly reduced species such as NADH and FADH2 ( for example produced during glycolysis and the citric acid cycle ) to establish an electrochemical gradient ( often a proton gradient ) across a membrane, resulting in an electrical potential or ion concentration difference across the membrane.

The use of ion channels has been shown to offer highly sensitive detection

Perfluorinated alkenes ( alkenes that have all hydrogens replaced by fluorine ) are highly prone to nucleophilic addition, for example by fluoride ion from caesium fluoride or silver ( I ) fluoride to give a perfluoroalkyl anion.

The high ionic radius of the Pb < sup > 2 +</ sup > ion renders it highly immobile in the matrix and hinders the movement of other ions ; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass ( 10 < sup > 8. 5 </ sup > vs 10 < sup > 6. 5 </ sup > Ohm · cm, DC at 250 ° C ).

There is a highly conserved sequence in roughly three quarters of all ORs that is a tripodal metal ion binding site, and Suslick has proposed that the ORs are in fact metalloproteins ( mostly likely with zinc, copper and possibly manganese ions ) that serve as a Lewis Acid site for binding of many odorant molecules.

These rocks have low concentrations of large ion lithophile elements ( LILE ), light rare earth elements ( LREE ), volatile elements and other highly incompatible elements.

Less commonly, SAgs attach to the polymorphic MHC class II β-chain in an interaction mediated by a zinc ion coordination complex between three SAg residues and a highly conserved region of the HLA-DR β chain.
