It is a particle ejected at a high speed from the nucleus of some, not all, radioactive atoms. ... Gamma rays are very similar to radio or light waves except that they have much more energy. ... The speed of the electrons is then increased around the nucleus because of the attractive force of opposite charges. ...
Today conductive plastics are being developed for many uses, such as in corrosion inhibitors, compact capacitors, antistatic coating, electromagnetic shielding of computers, and in "smart- windows that can vary the amount of light they allow to pass, etc. A second generation of electric polymers has also appeared (see below) in, e.g., transistors, light-emitting diodes, lasers with further applications such as in flat television screens, solar cells, etc. ... This could thus explain the lower conduction anisotropy compared to graphite Anisotropy is also interesting in other contexts of s...
biology Living things make up the world as we know it. Living things are involved in our life constantly, seeing that we are alive. There are five characteristics that are common to all living things. Living things are made up of one or more cells. Each cell is made up of living matter and is se...
