Liquefied petroleum gas (LPG) sensing properties of ZnO thin films consisting of sub-micron rods synthesized by chemical bath deposition (CBD) method are presented in depth. The scanning electron microscopy observation reveals that ZnO sub-micron rods are of hexagonal in phase grown perpendicular to

โฆ Synopsis
The yeast mediated reduction of ethyl acetoacetate to ethyl (S)-3-hydroxy butyrate proceeds with good yield and high enantioselectivity in liquefied petroleum gas (LPG). It was found that slightly more water (2 ml/g yeast) and more yeast (1.6 g/mmol substrate) were required to effect complete conversion than was the case with more conventional organic solvents, such as petroleum spirit.
