Several toxic fractions have been isolated from the salivary glands of " Ixodes holocyclus " but there has been variation in the reported molecular size of the principle paralysing toxin or toxins.
32.
Glycolic acid, having the smallest molecular size, is the AHA with greatest bioavailability and penetrates the skin most easily; this largely accounts for the popularity of this product in cosmetic applications.
33.
If you look at green ink in particular some have postulated that the reason for slow resolution is due to the molecular size of the green ink particles being significantly smaller than other colours.
34.
Methanol to gasoline processes favor molecular size-and shape-selective zeolite catalysts, and the STG + process also utilizes commercially available shape-selective catalysts, such as ZSM-5.
35.
The pore is narrowed at the funnel, which is formed by the six amino-terminal helices lining the wall of the channel, which thus determines the molecular size restriction at the channel entrance.
36.
By concluding that substances were expelled in order of molecular size as temperature increased, she helped classify coals and accurately predict their performance for fuel purposes and for production of wartime devices such as gas masks.
37.
When A _ { 12 } = A _ { 21 } = A, which implies molecules of same molecular size but different polarity, the equations reduce to the one-parameter Margules activity model:
38.
A sorption pump does pump all gases effectively with the exception of hydrogen, helium and neon which do not condensate at liquid nitrogen temperatures and are not efficiently adsorbed by the molecular sieves because of their small molecular size.
39.
In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small ( or zero for an ideal gas ), and the typical distance between neighboring molecules is much greater than the molecular size.
40.
The Van der Waals equation gives a better approximation when the size of the gas molecules cannot be neglected, and, as you would expect, it contains a term that " does " depend on the molecular size.
