ABSTRACT A conducting plastic has been used to create a new memory technology which has the potential to store a mega bit of data in a millimeter- square device-10 times denser than current magnetic memories. This device is cheap and fast‚ but cannot be rewritten‚ so would only be suitable for permanent storage. The device sandwiches a blob of a conducting polymer called PEDOT and a silicon diode between perpendicular wires. The key to the new technology was discovered by

Soil FRQ A) One chemical soil test we could do is a pH level test so we are able to tell what crops can grow in what areas. Other chemical tests include salinity‚ organic content (humus)‚ or the iron exchange capacity. One Physical Soil test we can do is pick up a handful of it and rub it together with our fingers to tell if it’s a soil heavy in clay‚ silt‚ or sand. Other physical tests include water-holding capacity porosity‚ moisture content‚ soil structure‚ or color. By completing these tests
