TFA is trifluoroacetic acid, which is corrosive, but not as dangerous as hydrofluoric acid. Its reactions are based on the carbonyl group.
The mechanism for tert-butyl ester deprotection using trifluoroacetic acid (TFA) involves the protonation of the oxygen atom in the ester group by TFA, leading to the cleavage of the tert-butyl group and formation of the corresponding carboxylic acid.
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
In general, exothermic reactions are faster than endothermic reactions. This is because exothermic reactions release energy, which can help drive the reaction forward more quickly.
For reactions involving gases, you can select reactions where the equilibrium constant Kp is equal to the equilibrium constant Kc.
the reactions in which value of Qc=Kc

In medical terms, TFA commonly stands for "Transfemoral Amputation," which refers to the surgical removal of a limb above the knee. It can also refer to "Tissue Factor Antigen," involved in the blood coagulation process. The context in which TFA is used is crucial for determining its specific meaning.

Total Flow Area
TFA ; a unit take out side fresh air to in side room / complax AHU ; a unit take inside air to conditioning air , remove heat from air , maintened temp. and give back that air to room
supplying fresh air at required temperature space that is tfa
There is only TFA the 'movie' ,season 1,2 and lastly 3.No more TFAs
TFA is pretty nasty, so I'll go with that.

The Autobots crash in Lake Erie, Michigan. But after leaving the lake, the Autobots end up in Detroit, Michigan.
TFA provides assistance in ionisation in the matrix, providing both ions and absorption at the wavelength of the MALDI laser.
Total Flow Area (TFA) is summation of nozzle areas which fluid can pass through. When you consider about the TFA, you need to count all nozzles that you have in a bit or a reamer. " http://www.drillingformulas.com/total-flow-area-tfa/ "
