Definition: A device or person that causes excitement or stimulation, often used in electrical contexts to provide current or frequency for other machines.

Example: The exciter in the generator ensures that it operates efficiently by supplying the necessary current.

Definition: A type of excited state in a material, where an electron is bound to a hole, allowing energy to move through the material without carrying a net charge.

Example: The exciton plays a crucial role in the efficiency of solar cells by facilitating energy transfer.

Definition: Relating to a type of quasiparticle formed when an electron and a hole bind together in a material, often studied in the field of excitonics.

Example: The researchers published a paper on excitonic effects in semiconductor materials.

Definition: A type of nerve that, when stimulated, causes an increase in activity in the part of the body it connects to.

Example: The excitor nerve played a crucial role in enhancing muscle movement during the exercise.

Definition: Describing a process that releases energy, often used in chemistry and biology to refer to reactions that give off energy.

Example: The exergonic reaction produced heat and light as it occurred.

Definition: A person who removes a body from a grave or tomb, usually for examination or investigation.

Example: The exhumer carefully dug up the remains to gather evidence for the investigation.

Definition: The outer layer that forms the wall of a spore or pollen grain.

Example: The exine protects the pollen grain during its development.

Definition: Relating to the study of life beyond Earth, especially the possibility of extraterrestrial life.

Example: Scientists are researching exobiological conditions on Mars to determine if life could exist there.

Definition: A scientist who studies life beyond Earth, focusing on the possibility of life on other planets or celestial bodies.

Example: The exobiologist presented her findings on the potential for microbial life on Mars.

Definition: This is a field of science that studies the possibility of life beyond Earth and how living things might be affected by environments in space.

Example: Scientists in exobiology explore the potential for life on other planets.
