4.4.2 Explain the electrical conductivity and malleability of metals IB Chemistry
4.4.2 Explain the electrical conductivity and malleability of metals IB Chemistry
Metals are malleable (bendy) since the metallic ions have some freedom to move in the structure since the metallic bonds are uni-directional. Ionic compounds will crack. Anything with "Freely Moving Charged Particles" will conduct electricity which in the case of metals is the delocalized sea of electrons.

Carbon nano cone electrical properties measurement
Carbon nano cone electrical properties measurement
During the autumn 2007 an in-situ TEM studie was made on carbon nano cones to measure the electrical conductivity. As usual the electrical contact resistance in these two probe measurements are unknown. However there is a work around by measuring the resistance at several sites along the length/height of the cone as this movie shows. The blog gives the rest of the details.

Highly Conductive Film That Can Stretch : DigInfo
Highly Conductive Film That Can Stretch : DigInfo
DigInfo - www.diginfo.tv In a world-leading initiative, a research group led by Takao Someya at the University of Tokyo has developed a material that has high electrical conductivity, but can stretch and contract like rubber. The group has used this material to make integrated circuits containing organic transistors. Recently, carbon nanotubes dispersed in polymers have been used in efforts to create conductive materials that can stretch and contract. However, carbon nanotubes clump together, and this problem has prevented researchers from obtaining the desired characteristics. Someyas group solved the clumping problem by dispersing the nanotubes in an ionic liquid before mixing it with a polymer. The resulting material, with its uniformly dispersed nanotubes, shows hardly any change in electrical conductivity even when stretched by up to 70%. Someyas group has used this elastic material to make a large integrated circuit, and is studying how to incorporate sensors for temperature, pressure, ultrasound, and light. Such a large, flexible sensor could be attached to the surface of a robot, to give the robot a sense of touch similar to that of human skin. The group is also working to create a flexible Braille display, by building in actuators instead of sensors. Artificial Skin

Conductive glas selfmade DIY Solar cell transparent electrode ITO SnO2 tinoxide semiconductor
Conductive glas selfmade DIY Solar cell transparent electrode ITO SnO2 tinoxide semiconductor
www.overunity.com How to make a selfmade DIY conductive glas transparent electrode with low resistance ITO SnO2 tinoxide semiconductor layer for a selfmade DIY Solar cell solarcell. Great easy way to make glas electrical conductive and have a transparent electrode layer fro Graetzel solarcells and a solarpanel . Here are the staps to make it: 1. Dissolve 5 Gramms of wet SnCl4 in 5 mL Methanol 2. Place a tile with the shiny side up into the oven 3. Heat the oven at 600 degrees 4. Place a heat resistent microscope slide on another tile into the oven 5. Let it heat for about 10 minutes and pull it out via the tile again when it is hot enough! 6. Spray the glas slide with the SnCl4 solution 7. Put it back into the oven for about 2 minutes and pull it then out again 8. Spray it again with the SnCl4 solution and put it back into the oven again and repeat this process until the desired electrical conductivity is reached. Due to the heat the SnCl4 decomposes to SnO2. Don´t breath the fumes and do it only in a well ventilated area, best outside ! 9. Test the electrical conductivity with a digital ohmmeter and repeat the spraying-heating process until you are satisfied with the electrical resistance of the SnO2 layer. This video is from the Youtube user HJesu who gave me permission to copy it to my Youtube channel. www.youtube.com This will make it very easy to selfbuild great and big selfmade Solarcells. Enjoy ! Regards, Stefan.
