Terahertz nondestructive evaluation (THz NDE) is a technique that utilizes terahertz (THz) radiation, which falls in the frequency range between microwave and infrared radiation (approximately 0.1 to 10 THz), to inspect and analyze materials and structures without causing any damage. This method exploits the unique interaction of THz waves with different materials, enabling the detection of flaws, moisture content, and other properties.
Surface diffusion is a process in which atoms or molecules move along the surface of a solid material. This movement occurs as a result of thermal energy, allowing species to hop from one site to another on the surface. It plays a critical role in various physical and chemical phenomena, including thin film growth, adsorption/desorption processes, catalysis, and sintering.
In chemistry, the term "texture" can refer to various aspects depending on the context, including the physical characteristics of a substance, the arrangement of its components, or the way it interacts with other materials. Here are some common interpretations: 1. **Solid Samples:** In solid materials, texture relates to the size, shape, and arrangement of the particles or crystals within the solid. This can affect properties such as hardness, strength, and reactivity.
Tribology is the study of friction, wear, and lubrication between surfaces in relative motion. It encompasses the science and engineering aspects of how surfaces interact, the mechanisms of contact, and the ways to reduce friction and wear for better performance and longevity of mechanical systems. Key components of tribology include: 1. **Friction**: The resistance to sliding or rolling motion when two surfaces come into contact. Understanding friction helps in designing systems that either minimize energy loss or enhance control.
In geometry, a volume solid (often referred to simply as a "solid") is a three-dimensional object that occupies a certain amount of space.

Volume solids can be categorized into various types based on their shapes and properties. Common examples of volume solids include: 1. **Cubes**: A solid with six equal square faces.
Urbach energy is a parameter that characterizes the tail of the absorption spectrum of a semiconductor or insulator near its band edge. It is named after the physicist Emil Urbach, who studied the exponential absorption edge in disordered materials. In semiconductors and insulators, the absorption of light occurs when photons have enough energy to excite electrons from the valence band to the conduction band.

Pinned article: Introduction to the OurBigBook Project

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.
