The Vienna University of Technology, in collaboration with the dental company Ivoclar Vivadent, has now developed a new generation of photoactive materials based on the element Germanium. Similar to natural tooth enamel, modern dental composites consist of a mixture of different material components.
Check the bake element. Turn your range OFF and either remove the fuses or turn the breaker OFF. Then unplug the range. Carefully inspect the bake element (lower element) for cracks or breaks. If it is cracked or broken, it will need to be replaced. Purchase a GE Appliance part or accessory online.

May 28, 2019· A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a siliconsilicongermanium alloy is commonly used to increase transmission speed of electrical signals. Individual electrical component speed adds up as an aggregate, and, therefore, a germanium transistor array can significantly increase the processing speed of a circuit.

Mendeleev in his periodic table left some spaces below Al and called it as Eka Al ( presently it is the Gallium ). By this name he tells the up coming chemists that there is a new element with the property of he contributes in discovery of Gallium...! 1 person found this useful.
As a semiconductor element, Germanium has a small band gap that allows it to efficiently respond to infrared light. The two important characteristics of Germanium that brings about healthy function effects are its natural ability to balance the body's ions (bioelectricity) and the penetration of Far Infrared Rays into the human body.
