Breathing, effect

A crude estimate of the breathing effect can be made by treating the linear chain as if it were tethered at its midpoint, i.e., like a 2-arm star", thus completely ignoring the effect of its diffusion history along the tube. In that case... 

Precautions Poison by swallowing and skin contact. Mildly toxic by breathing. Effects on the body by swallowing are changes in motor activity, muscle weakness, and sweating. Avoid cat flea collars with this ingredient, as it is harmful...

Precautions Moderately toxic by breathing. Effects on the human body by breathing are general anesthetic, decreased pulse rate without blood pressure fall, and body temperature decrease. An asphyxiant. Moderate explosion hazard. 

Precautions A skin irritant. Toxic by swallowing. Causes nausea, vomiting, cramps, diarrhea, rectal spasms, thirst, dizziness, sleepiness, and confusion. Large doses can cause fever, disturbance of heart rhythms, and breathing effects.

Future work incorporating unsteady inhalation and expiration cycle is intended, to look at the full breathing effect on the tongue dynamics. Ultimately, a realistic pharyngeal airway model is also intended to be used for further fluid-structure interaction investigation. 

This peculiarity induces unprecedented very large breathing effects, but in contrast to MIL-53, the input (solvent) is associated with an expansion of the framework (Fig. 14). The extent of these swellings (most of the time reversible) strongly depends on the nature of the dicarboxylate linking the trimers in the solids.

De Vos and coauthors [220] studied the differences in adsorption of hnear and branched hydrocarbons in the Cu-based MOF structure. The data obtained provide evidence for definite preferences of the linear alkanes in the adsorption. Quite a few examples of the so-called molecular recognition by MOFs were reported in the literature, the predominant adsorption of certain isomers over the other, such as p-dichlorobenzene or p-xylene compared to m-isomers or linear alkanes compared to the branched molecules is meant by this term. Another interesting feature of the MOF materials is the breathing effect, which is revealed as the changes in the pore diameter depending on the nature of the adsorbate (Fig. 14) [8,221],...

MHz, and of 0.15 (Fig. 12B). This finding indicates the high sensitivity of Al solid-state NMR spectroscopy on framework aluminum atoms in MIL-53(A1) to their interactions with adsorbate molecules and to structural transformations. So, the breathing effect (open-closed framework interconversion) of the framework of MIL-53 and influence on it of different adsorbates can be investigated with Al MAS NMR.
