A unique method for synthesis of graphene wrapped carbon nanotubes was developed by chemical vapor deposition. Raman analyses show that defects have been created during growth which helps in the efficient dispersion of the composites in a variety of solvents. The synergistic combination of 2D graphene and 1D carbon na…

Microorganisms have evolved different systems for storing carbon during times of stress. In the cell's natural environment, the stored carbon can then be utilized for growth when other nutrients are in better supply. Storage of carbon and other nutrients is ubiquitous throughout the prokaryotic and eukaryotic domains…

Polyethylene is the largest volume polymer produced globally, with a total over 90 million metric tons per annum. Since its accidental discovery in 1933 it has evolved into a material critical to modern life. The first product commercialized was low density polyethylene (LDPE) based on free radical polymerization. Sho…

Three novel chelators based on the 6-amino-6-methylperhydro-1,4-diazepine scaffold and possessing three pendant N-acetic or N-α-methylacetic acid have been synthesised. The ligands contain six donor atoms for complexation of Mn(II) ions and thus potentially leave an additional site for coordination of a water molecule…
