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: Referring to something that is extremely heavy or has a very large atomic weight, particularly elements that are heavier than fermium in the periodic table.

Example: The ultraheavy elements are often studied for their unique properties and potential applications in science.

Definition: Extremely light in weight or mass, often used to describe materials or products that are designed to be as light as possible.

Example: The ultralight backpack made hiking much easier and more enjoyable.

Definition: A very light aircraft designed for recreational use, usually made from lightweight materials and powered by a small engine, often meant for one person.

Example: He flew his ultralight over the beautiful landscape.

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: Extremely small in size, often used to describe objects that are much smaller than usual.

Example: The artist created an ultraminiature sculpture that could fit on a pencil tip.

Definition: Extremely modern in ideas or style; completely up-to-date.

Example: The building features an ultramodern design that attracts many visitors.

Definition: Relating to something that is extremely physical or beyond the normal physical realm.

Example: The ultraphysical aspects of the performance left the audience in awe.

Definition: This word describes something that is extremely clean or free from any impurities.

Example: The laboratory used ultrapure water for their experiments to ensure accurate results.
