Abstract Carbon nanotubes‚ in different forms and architectures‚ have demonstrated good promise as electrode material for Li-ion batteries‚ owing to large surface area‚ shorter Li-conduction distance and high electrical conductivity. However‚ practical application of such Li-ion batteries demands higher volumetric capacity‚ which is otherwise low for most nanomaterials‚ used as electrodes. In order to address

experiment I am investigating the relationship between surface area and the volume of a model cactus and to determine whether this relationship affects the loss of water. We used oasis blocks‚ an absorbant material used by florists as a substitute for a cactus‚ that would soak up the water‚ and thus ideally show the percentage water loss by weighing the before and after evaporation weights. Independent Variable The independent variable is the total surface area for each size of the blocks and I think

Evaporation? Aim * To find out if changes in temperature‚ draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given Prediction * I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation in the water * I believe

Find the Right Location 1. Observe the flow of water from rooftops‚ driveways‚ or other hard surfaces and place the rain garden where the water collects. 2. Select an area on marginally sloping or flat land. 3. Calculate the slope of your lawn (continued below). 4. Pick a spot that has full to partial sun if possible. 5. Place the rain garden at least 10’ away from a building/housing structure. 6. Call 811 or 1-800-522-6543 for OKIE811‚ the Oklahoma Company for damage prevention information before

all serve the same basic purpose. They are made to absorb liquids. It doesn’t matter if the sponge is from the sea‚ or from a factory‚ they both use wicking and surface tension in order to absorb sponges. This use is what allowed the sponge to soak its way into history. Sponge absorption is the key power that utilizes wicking and surface tension to soak up liquids. Wicking‚ or capillary action‚ allows water to be stored in sponges when they soak up liquids. According to World Book Student‚ capillary
