Definition: Relating to a method of analysis that measures the current produced by a chemical reaction in a solution as a function of the applied voltage.

Example: The polarographic technique is often used in electrochemistry to analyze substances in solution.

Definition: A technique used in chemistry to analyze substances by measuring the current that flows through a solution as the voltage is changed.

Example: Scientists often use polarography to determine the concentration of different ions in a solution.

Definition: A type of quasiparticle formed when an electron or hole interacts with the surrounding lattice in a material, causing a distortion in the lattice structure.

Example: In certain materials, the behavior of a polaron can significantly affect their electrical properties.

Definition: Describing something that does not have a pole or is lacking a pole.

Example: The tent was designed to be poleless, making it easier to set up in windy conditions.

Definition: A star that is used for navigation because it is always in the same position in the sky, often referred to as Polaris. It can also mean a guiding principle or center of attraction.

Example: In times of uncertainty, her values served as a polestar for making decisions.

Definition: A serious infectious disease that affects the nervous system and can cause paralysis, especially in children.

Example: Vaccination has greatly reduced the incidence of polio around the world.

Definition: A serious viral illness that mainly affects children and can cause paralysis and muscle weakness. It is preventable with vaccines and is also known as infantile paralysis.

Example: Vaccination has significantly reduced the number of cases of poliomyelitis worldwide.

Definition: A type of virus that can cause a disease called poliomyelitis, which affects the nervous system and can lead to paralysis.

Example: The poliovirus is responsible for outbreaks of polio in various parts of the world.

Definition: A person or thing that helps to transfer pollen from one flower to another, which is necessary for plants to produce seeds and fruit.

Example: Bees are important pollenizers that help many plants reproduce by spreading pollen.

Definition: A condition caused by an allergic reaction to pollen, often resulting in symptoms like sneezing, runny nose, and itchy eyes.

Example: Many people suffer from pollenosis during the spring when pollen levels are high.
