Nano is a prefix derived from the Greek word for dwarf. The parts of the U. S. National Nanotechnology Initiative (NNI) definition that are relevant for this review define nanoscale materials as having at least one dimension in the range of 1 to 100 nanometers (nm), with properties that ...
Students make qualitative observations of the relative force required to blow bubbles into the syrup solutions with a straw as an analog for comparing the effects of viscosity on the formation and bursting behavior of gas bubbles in magma. During class, students observe syrup "lava flows" flowing...
Nanotechnology presents the possibility of revolutionizing many aspects of our lives. People in many settings (academic, small and large industrial, and the general public in industrialized nations) are either developing or using engineered nanomaterials
