Benzene Pollution is a colourless or light-yellow chemical that is liquid at room temperature. It has a sweet odour and is highly flammable. Benzene is formed from both natural processes and human activities. Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Normal environmental concentrations of benzene are unlikely to damage… Continue reading Benzene Pollution

Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries
Carbon nanotubes (CNTs) Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter measured to less than 1 nanometer (nm). They are very lightweight, almost 1/6th of the steel with a mechanical tensile strength of almost 400 times that of steel.… Continue reading Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries
