Polymers
Nylon was one of the first commercial polymers of all time developed. It was foremost invented by a squad of chemists at the Du Pont de Nemours and Company research installation in the 1930 s. This squad was led by Dr. Wallace Hume Carothers. The end of nylon was to make a polymer that was…
Inferring Relative Permeability from Resistivity Well Logging
Chemistry
Inferring Relative Permeability from Resistivity Well Logging Introduction Permeability is a chattel of a spongy medium that measures the capacity of a substance to transmit fluids. Generally, permeability that is applied in petroleum industry is steady in Darcy’s flow equation which compares pressure gradient, flow rate and fluid properties. However, a formation has permeability regardless…
Comparison of the Heavy Metal Bioaccumulation Capacity of Epiphytic Moss and Lichen
Chemistry
Biomonitors are organisms used to monitor pollution and air quality in specific areas. Air pollution can cause the bioaccumulation of elements, especially heavy metals, into these organisms. This makes them perfectly suited for studying several parameters that would give an idea about the degree of air pollution in that area. In this study, the heavy…
