This study was aimed to investigate the effects of the size of material, extraction time (60, 90, 120,150,180 and 210 minutes), water-to-material ratio (5:1, 10:1, 15:1, 20:1, 25:1 and 30:1 ml/g) and extraction temperature (110, 120,130, 140, 150, and 140°C) on the essential oil yield accruing from extraction of white pepper cultivated in Phu Quoc, Vietnam.
However, when this ratio exceeds 20:1 (g/g), the essential oil yield is only 2.4 (mL/g) at a ratio of 30:1 (g/g).

The InGaAs samples were dipped in acidic solutions such as 1/101 diluted HCl and HNO3 and 1/1/100 HCl/H2O2/H2O (CPM) and HNO3/H2O2/H2O (NPM).
Cross-sectional SEM images of the etching profiles of InGaAs (001) surface before and after wet treatments are shown in Fig. 1.
However, in 1/1/100 CPM and NPM, the thickness of the InGaAs layer decreased to 549 and 221 nm, respectively.
Figs. 1 and 2 show that the CPM-treated InGaAs surface had a much lower etching rate than the NPM-treated one.
