The present study aims to identify nanoparticles amenable to the decrease of erosion and corrosion in various working states.  In this regard it is argued that the negative effects on erosion and corrosion imposed due to the presence of nanoparticles are reflected from the nanoparticles shape. In this situation, WS2 featured by possessing an almost round shape is suitable for decreasing the ero...

introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
