| nucleoli |
In biology, the nucleolus is, strictly speaking, a "suborganelle" of the cell nucleus, which is an organelle. Only plant and animal nuclei have nucleoluses. Most plant and animal cells have one or more nucleoluses although some do not. No membrane separates the nucleolus from the nucleoplasm. The nucleolus are made of protein and ribonucleic acid (RNA) and contains proteins as well as ribosomal RNA. ...

| nucleophile |
In chemistry, a nucleophile (literally nucleus lover) is a reagent which is attracted to centres of positive charge. A nucleophile participates in a chemical reaction by donating electrons to a species known as an electrophile in order to form a chemical bond. Because nucleophiles donate electrons, they are by definition Lewis bases (see acid-base reaction theories). ...

| nuclear chemistry |
Nuclear chemistry is a subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties. It may be divided into the following categories: * Radiochemistry deals with the use of radioactivity to study ordinary chemical reactions* The application of techniques from chemistry to study nuclear reactions such as fission and fusion — see also nuclear physics. ...

| nuclear energy |
Nuclear power currently involves converting the nuclear energy of fissable uranium into thermal energy by fission, from thermal to kinetic energy by means of a steam turbine and finally to electron energy by a generator. Nuclear reactors currently use nuclear power to provide about 17% of the world's electricity and 7% of global energy. ...

| nuclear energy |
Nuclear energy is energy released from the nucleus of an atom by the conversion of its mass to energy consistent with Albert Einstien's formula E=mc?in which E = Energy, m = Mass and c = the Constant Speed of Light. Nuclear energy is released by one of three nuclear reactions:*Fission, the breaking of the binding forces of an atom's nucleus.*Fusion, the fusing together of atomic particles.*Decay, which is the natural and much slower form of Fission. ...
