New attention to trifluoracetic acid, or TFA, underscores the game of whack-a-mole that scientists and communities face with ...

A chemical that’s in everything from fridges to air-conditioning and is linked to birth defects is accumulating in our blood and drinking water.

A growing body of research has raised concerns about a forever chemical known as TFA, which is short for trifluoroacetic acid ...

A colossal rockslide into Greenland’s Dickson Fjord scoured the surface of a glacier that fed the narrow channel, as shown in ...

In this transformation, trifluoroacetic acid (TFA) was used as the optimal solvent and played an important role in the ...

The sections were immediately transferred to a cold room (4 °C), where 10 μl of matrix (sinapinic acid, 10 mg/ml in acetonitrile/0.05% trifluoroacetic acid 50:50) were deposited with a pipette ...

Stop the reaction by addition of 1.5 μl of 0.1% trifluoroacetic acid. 10| Fractionate the peptides by narrow-bore high-performance liquid chromatography. Subject the collected peptides to ...

Copper is an essential enzyme cofactor in bacteria, but excess copper is highly toxic. Bacteria can cope with copper stress by increasing copper resistance and initiating chemorepellent response.

Figure 5. Temperature dependence of the rate constant. Figure 6. Activation energy graph - Arrhenius plot. The reaction follows pseudo-first-order kinetics due to the fact that trifluoroacetic acid ...
