Bacterial diaper rash may be caused by several different organisms. The most common are Staphylococcus aureus (Staph), which also causes impetigo, and Group AStreptococcus (Strep), which usually is seen as strep throat.
A light-emitting diode (LED) is a semiconductor device that creates light using solid-state electronics. A diode is composed of a layer of electron rich material separated by a layer of electron deficient material which forms a junction.
Light Emitting Diodes (LEDs) MiniScience supplies the most useful LED lights for science and educational activities. These are generally LEDs that require very little voltage and very little current and produce a very bright light. In many science experiments such as making electricity from potato these LEDs play a major role in successful demonstration of the project.
