'RoSEM - True Beauty of Science that lies within'
The photograph is of the microstructure of a treated surface of contaminated petroleum waste with a combination of Portland cement and microsilica (which is a by-product from electric arc furnaces that are used in the manufacture of ferrosilicon or silicon metal), viewed after 28 days using the SEM (Scanning electron microscope) technique. The SEM image depicts various vivid patterns which give a sense of a composite design but one shape that stands out is that which most resembles a rose...hence the name 'roSEM'.
