The formation of a hydroxylated native oxide layer on Si(001) under wet conditions is studied by means of first principles molecular dynamics simulations. Water molecules are found to adsorb and dissociate on the oxidised surface leading to rupture of Si-O bonds and producing reactive sites for attack by dissolved dioxygen or hydrogen peroxide molecules. Tensile strain is found to enhance the d...

Subcritical water extraction of horse chestnut (Aesculus hippocastanum) parts, such as seeds, seed shell, bark and leaves has been performed in a batch reactor at temperatures 150, 200 250?C times 5, 15 30 min. The obtained extracts were analyzed by spectrophotometric methods to determine the total phenols, carbohydrates antioxidant activity. Furthermore, compounds detected extracts, triterpene...

The dumping of waste banana peels from local chip manufacturing has encouraged sustainable food trends to valorize these as pectin sources. In this study, soluble was extracted using a continuous subcritical water extraction system (SWE). This method promising fast process with solvent that environmentally friendly. Temperature (100 160 °C) and time (5 50 minutes) were manipulated, fixed pressu...

Ginger is one of the commonly used spices that has been exhibited to have pharmaceutical activities. These therapeutic properties are mainly attribute to gingerols and shogaols. To extract these bioactive compounds, subcritical water extraction (SWE) was employed as a green method. The influence of adding co-solvents, temperature, retention time and particle size on extraction yield were invest...
