Appearances of the composites synthesized.

Code	Visual inspection and other remarks on composites
MV001_NP, MV002_NP, MV003_NP	Black, loose, easy to crush, and gradually turns brownish on exposure to air
MV004_NP	Black, most gelling, strong, very difficult to crush, and remains black even after exposure to air
MV005_NP, MV006_NP	Gelling, strong, difficult to crush, and remains black even after exposure to air
MV007_NP	Gelling, strong, very difficult to crush, and remains black even after exposure to air
