Mobile phase A was 0.1% (v/v) formic acid aqueous solution and mobile phase B was acetonitrile. The gradient elution method was as follows: 0–1 min, 90%–80% A; 1–3 min, 80%–77.5% A; 3–3.5 min, ...

This paper reports on an investigation of the electrochemical behavior of Ti grade 2 and Ti6Al4V alloy in aqueous ... acetic and lactic acid, but can be corroded by others such as formic acid and ...

The chromatographic method employed was as follows: the column was a Welch Ultimate XB-C18 column (250 mm × 4.6 mm, 10 μm), the mobile phase was a gradient elution of 0.4% formic acid aqueous solution ...

We describe the various homogeneous catalysts available that usually operate in aqueous formic acid solutions. We also briefly describe the reverse reaction that would contribute to making the use of ...

Therefore, CDs with strong emissions in red to NIR region in aqueous solutions are highly desired ... of red emissive FA-CDs from citric acid and urea in FA without complicated purification ...

There are several solutions to stopping human-caused acid rain. Regulating the emissions coming from vehicles and buildings is an important step, according to the EPA. This can be done by ...

In the 50s of the last century Earland and Raven (1954) proposed the use of formic acid (FA), mixed with small quantities ... that they kept an amorphous state and remained stable in aqueous solution ...

Both bases have been studied in gas and solution phases. The interaction of adenine base ... Then hipoxanthine oxidation occurs assisted by an oxygen donor molecule (formic acid in this work) to give ...

HILIC requires more organic solvent than aqueous solvent in the mobile ... shape improvement when adding 0.01% of formic acid to the organic phase, using a bare silica column. Guillarme: Additives and ...
