Definition: This word describes something that works in a very effective way, achieving maximum results with minimal waste or effort.

Example: The new engine design is ultraefficient, using less fuel while providing more power.

Definition: A liquid that has passed through a filter during a process called ultrafiltration, which removes larger particles and allows smaller ones to pass through.

Example: The laboratory used ultrafiltrate to analyze the composition of the solution.

Definition: A process that separates small particles from larger ones by passing a liquid through a special filter that only allows tiny molecules to go through.

Example: Ultrafiltration is commonly used in water treatment to remove impurities.

Definition: Very dangerous or risky, often to a high degree.

Example: The chemical plant was labeled as ultrahazardous due to the toxic materials it handled.

Definition: A type of microscope that uses strong light to see very tiny objects that cannot be seen with a regular microscope.

Example: The scientist used an ultramicroscope to observe the behavior of colloidal particles.

Definition: A tool used to cut very thin slices of materials, especially for examining them under an electron microscope.

Example: The scientist used an ultramicrotome to prepare samples for detailed analysis.

Definition: A technique in microscopy that involves cutting very thin sections of a specimen using a specialized instrument called an ultramicrotome.

Example: Ultramicrotomy is essential for preparing samples for electron microscopy.

Definition: A person who has very modern ideas or styles and strongly believes in contemporary views.

Example: The ultramodernist artist created works that challenged traditional forms and embraced new technologies.

Definition: Very accurate and exact, leaving no room for error.

Example: The scientist used an ultraprecise instrument to measure the tiny particles.

Definition: Very close to reality, making something appear as real as possible.

Example: The artist created an ultrarealistic painting that looked like a photograph.
