Interfacial rheology is the study of the mechanical properties and behavior of interfaces, typically between two immiscible phases, such as liquids, gases, or solids. This field focuses on how forces and deformations affect the interface and how the interfacial properties influence the overall behavior of the materials involved.
Hydrogel encapsulation of quantum dots refers to the process of incorporating quantum dots (QDs)—nanoscale semiconductor particles with unique optical and electronic properties—into a hydrogel matrix. Hydrogel is a three-dimensional network of hydrophilic polymer chains that can hold a large amount of water and is often used for various biomedical and technological applications.
The Hertz–Knudsen equation is a fundamental relationship in physical chemistry used to describe the evaporation and condensation of a substance in the context of phase transitions, particularly at the interface between a liquid and vapor or a solid and vapor. The equation provides a way to relate the pressure of a vapor in equilibrium with its liquid phase to the rate of evaporation and the molecular characteristics of the substance.
Helium-3 surface spin echo is a technique used primarily in the field of condensed matter physics to probe the properties of liquid helium-3 (³He) near surfaces, usually in the context of studies involving superfluidity and quantum phenomena. Helium-3 is notable because it is a fermionic isotope of helium, and it can exhibit superfluid behavior at very low temperatures.
Surface tension is a physical property of liquids that describes the elastic tendency of a fluid surface. It is the result of the cohesive forces between liquid molecules at the surface, which causes them to contract and minimizes the surface area. Surface tension is typically measured in units of force per unit length, often expressed in dynes per centimeter (dyn/cm) or newtons per meter (N/m). The values of surface tension can vary widely among different liquids.
The Du Noüy-Padday method is an experimental technique used to determine the surface tension of liquids. It is widely utilized in various fields, including chemistry, materials science, and biomedical applications. This method involves measuring the force required to detach a solid object, typically a ring or a drop, from the surface of a liquid. ### Key Points of the Du Noüy-Padday Method: 1. **Apparatus**: The apparatus typically includes a ring that is submerged in the liquid.
Disjoining pressure is a concept in physical chemistry and materials science that refers to the pressure difference across a thin film or interface due to molecular interactions and forces. It is particularly relevant in the study of thin liquid films, such as those found in emulsions, foams, or biological membranes. Disjoining pressure arises from three primary sources: 1. **Van der Waals Forces**: These are attractive forces that can cause thin films to collapse when the film thickness is reduced.
The Davisson–Germer Prize in Atomic or Surface Physics is an award established by the American Physical Society (APS) in honor of Clinton Davisson and Lester Germer, who are known for their foundational work in the field of electron diffraction and the study of surface phenomena. The prize recognizes and honors outstanding achievements in atomic or surface physics, with a focus on fundamental contributions that advance the understanding of these fields.
Superhydrophilicity refers to the extreme affinity of a surface to water, resulting in a very high contact angle hysteresis and the ability to attract and spread water droplets over the surface. In practical terms, materials exhibiting superhydrophilicity have low contact angles (typically less than 10 degrees), meaning that water droplets spread out almost completely on the surface rather than forming beads.
Supercritical adsorption refers to the process of adsorbing molecules from a supercritical fluid onto a solid adsorbent. A supercritical fluid is a state of matter that shares properties of both gases and liquids. It occurs when a substance is above its critical temperature and critical pressure, allowing it to diffuse through solids like a gas while maintaining a higher density and solvating ability similar to that of a liquid.
Stiction by Wikipedia Bot 0
Stiction is a term that describes the phenomenon of static friction that needs to be overcome to initiate movement between two surfaces that are in contact with each other. It occurs when the forces holding the two surfaces together are stronger than the forces that allow them to slide against each other, resulting in a "stickiness.
Supersonic transport refers to aircraft capable of flying faster than the speed of sound, which is approximately 343 meters per second (1,125 feet per second) at sea level in dry air at 20°C (68°F). This speed is commonly referred to as Mach 1. Aircraft designed for supersonic transport are typically characterized by their aerodynamic shapes, powerful engines, and specialized design features to handle the challenges associated with flying at such high speeds.

As of my last knowledge update in October 2021, there is no widely known public figure or concept named Steve Alleyne. It is possible that he is a private individual or someone who has gained prominence after that date.
Cassie's law by Wikipedia Bot 0
"Cassie's Law" refers to a piece of legislation that was introduced in various jurisdictions to address the issue of domestic violence and to enhance protections for victims. The name is often derived from a case involving an individual named Cassie, who may have suffered from domestic violence or whose story highlighted the gaps in existing laws and protections for victims. While specific details vary by location, Cassie's Law typically aims to: 1. Improve the reporting and response mechanisms for domestic violence incidents.
The Captive Bubble Method (CBM) is a technique used primarily in the field of materials science, particularly in the study of the properties of porous materials and the measurement of fluid permeability. This method involves creating a controlled environment in which a gas bubble is trapped within a porous medium. The primary goal is to analyze the behavior of the bubble as it interacts with the surrounding material, often to understand how liquids or gases move through porous structures.
The Sud Aviation Super-Caravelle is a French twin-engine jet airliner that was developed in the 1960s. It is an extended version of the earlier Sud Aviation Caravelle, which was one of the first jets designed specifically for short and medium-haul passenger flights. The Super-Caravelle featured improvements in range, capacity, and performance compared to its predecessor.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
