Analyzing Biocomposite Morphologies and Compositions

The morphologies and the elemental compositions of the developed biocomposites were analyzed by means of a Verios G4 UC scanning electron microscope (Thermo Scientific, Brno, Czech Republic) equipped with an energy dispersive X-ray spectroscopy analyzer (Octane Elect Super SDD detector, EDAX-AMETEK, Mahwah, NJ, USA) [67 (link)]. Before analysis, the samples were fractured in liquid nitrogen and dried, then fixed on aluminum stubs with double-adhesive carbon tape and coated with 10 nm gold using a Leica EM ACE200 Sputter coater (Leica Microsystem, Vienna, Austria) to provide material deterioration during electron beam exposure. SEM investigations were performed in high vacuum mode using a secondary electron detector (Everhart-Thornley detector, ETD) at an accelerating voltage of 10 kV.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
