Scanning electron microscope (SEM) analysis showed that the surface of the coal sample became smoother and the pore size decreased after citric acid treatment. In conclusion, citric acid has a good inhibitory effect on different types of coal. select article Defining kerogen maturity from orbital ...

This refers to the extent to which the results from one study are relevant to other contexts which in turn could be affected by how representative the sample is [16]. To this end, we had discussed how representative and information-rich samples were selected from the community itself and we...
From laboratory practices, it transpires that even after a very short period of storage, the oxidative stability of the biodiesel exceeds the values required by European regulations. Therefore, the goal of this work was to devise a parameter (marker) allowing for fast and convenient identification...
