Quantifying the contact area and force applied by an atomic force microscope (AFM) probe tip to a sample surface enables nanoscale mechanical property determination. Best practices to implement AFM cantilever-based nanoindentation in air or fluid on soft and hard samples to measure elastic modulus or other nanomechanical properties are discussed.

The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.LipidsThe most...

Source: Laboratory of Alan Lester - University of Colorado Boulder The physical properties of minerals comprise various measurable and discernible attributes, including color, streak, magnetic properties, hardness, crystal growth form, and crystal cleavage. Each of these properties are mineral-specific, and they are fundamentally related to a particular mineral’s chemical make-up and atomic structure. This experiment examines two properties that stem primarily from symmetric repetition of...

The characteristics that enable us to distinguish one substance from another are called properties. Physical Properties of Matter A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter...

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.
FAQs
Density provides a key basis for analyzing buoyant forces because it characterizes how much matter occupies a given volume. When combined with pressure information, it helps physicists evaluate how a fluid supports or resists an immersed object. This relationship is important in studying floating behavior and other hydrostatic situations.
Viscosity determines how strongly a fluid resists internal motion. A highly viscous fluid deforms and flows less readily, whereas a fluid with lower viscosity changes motion more easily under comparable conditions. Accounting for this property helps explain flow behavior in systems such as pipelines, pumps, and other fluid-handling designs.
Pressure differences provide a driving influence for fluid flow, while pressure within a fluid can transmit force through the system. Examining how pressure varies across a fluid therefore helps connect applied forces with motion and buoyancy. This principle supports analysis of hydrostatics, fluid dynamics, pumps, and pipelines.
Compressibility describes how readily a fluid changes volume when conditions vary. That response becomes especially relevant when analyzing disturbances that travel through a fluid, as well as processes involving changes in temperature and state. Including compressibility allows physical models to address waves and thermal behavior rather than treating every fluid response as purely rigid.
A practical analysis begins by identifying the dominant behavior: density and pressure for hydrostatic effects, viscosity for resistance to flow, compressibility for volume changes and wave behavior, and surface tension for boundary interactions. Selecting properties this way connects measurable characteristics with the physical outcome being modeled, improving interpretation of fluid systems.
Fluid properties support investigations across atmospheric and oceanic behavior, where pressure, density, and compressibility help characterize large-scale fluid systems. They also inform the design and analysis of pipelines, pumps, aircraft, and biomedical devices. In each case, the relevant properties connect environmental or operating conditions with flow, force transmission, or boundary effects.
