When these trained flies were then presented with a completely new and unrelated choice of normal vs . deuterated odorants, they avoided or preferred deuterium as with the previous pair.
42.
Because of these factors, as well as the much larger incoherent scattering cross section of protium, ordinary proteins cannot be imaged as well as those that are fully deuterated.
43.
In the March 8, 2002 issue of the peer-reviewed journal " deuterated acetone ( ) showed measurements of tritium and neutron output consistent with the occurrence of fusion.
44.
Another remarkable manifestation of this property is their reluctance to surrender the pyridine ligand ( for example in exchange for deuterated pyridine d 5-Py ), even at 200 �C.
45.
It was proposed in 1999 that it might be possible to achieve single-residue resolution by using collision-induced dissociation fragmentation of deuterated peptides in conjunction with tandem mass spectrometry.
46.
Two years later, in 2013, Turin and colleagues published a study in PLoS ONE showing that humans easily distinguish gas-chromatography-purified deuterated musk in double-blind tests.
47.
Deuterated solvents are needed, as they don't give a signal under a magnet, as it is a paired proton, allowing only the signal from the sample to be detected.
48.
In 1992, Schilke et al . measured abundances of HNC, HCN, and deuterated analogs along the OMC-1 ridge and core and confirmed the temperature dependence of the abundance ratio.
49.
Hence, the lower zero-point energy of the deuterated species translates into a larger activation energy for its reaction, as shown in the following figure, leading to a normal kinetic isotope effect.
50.
Regular KDP has absorbances at this wavelength of approximately 4.7 6.3 % / cm of thickness while highly deuterated KDP has absorbances of typically less than 0.8 % / cm.
