Micro-compounding generally refers to the process of creating very small-scale compounded pharmaceuticals or formulations that are typically prepared by a licensed pharmacist or a specialized compounding pharmacy. This practice allows for the customization of medications to meet the unique needs of individual patients, such as altering dosage forms, flavors, or delivery methods.
Poly(p-phenylene) is a type of conducting polymer, which consists of a linear chain of repeating units derived from para-substituted phenylene units. Its chemical structure is characterized by alternating single and double carbon-carbon bonds in the backbone, leading to a conjugated system that allows for electrical conductivity.
Poly(phthalaldehyde) (PPA) is a thermoplastic polymer known for its unique properties, such as high rigidity, thermal stability, and good chemical resistance. It is derived from phthalaldehyde, a compound that can polymerize to form this high-performance material. PPA has been studied for various applications, including in the production of engineering plastics and coatings, as well as composite materials. Its advantages include a high glass transition temperature and the ability to maintain mechanical strength at elevated temperatures.
Seasoning is a process used primarily with cast iron and carbon steel cookware to create a non-stick surface and to protect the metal from rusting. The process involves coating the surface of the cookware with a layer of oil and then heating it to a high temperature. This causes the oil to polymerize, forming a hard, protective layer on the cookware.
The term "reactive center" can refer to different concepts depending on the context, including chemistry, biochemistry, and cellular biology. Here are a few interpretations: 1. **In Chemistry**: The reactive center often refers to a part of a molecule where a reaction is likely to occur. This could be a functional group such as a carbonyl group, amine, or reactive metal center in coordination complexes.
The Newton polytope is a geometric object associated with a polynomial function, particularly in the context of algebraic geometry and combinatorial geometry. It provides a way to study the roots of a polynomial and the properties of the polynomial itself by examining the combinatorial structure of its coefficients.
The Ziegler–Natta catalyst is a type of catalyst used in the polymerization of alkenes, particularly ethylene and propylene, to produce high-performance polymers such as polyethylene and polypropylene. Developed in the early 1950s by chemists Karl Ziegler and Giulio Natta, these catalysts are significant in the field of polymer science.
Solvent Vapor Annealing (SVA) is a technique used to improve the properties of thin polymer films and other materials by utilizing the controlled exposure to solvent vapors. The process involves placing a polymer film in an environment containing the solvent in its vapor form, allowing the solvent to diffuse into the film.
Actuarial polynomials are specific mathematical tools used primarily in actuarial science, often in the context of modeling and calculating insurance liabilities, annuities, and life contingencies. They can be used to represent functions that describe various actuarial processes or outcomes.
Silicon carbide (SiC) is a compound of silicon and carbon that possesses a variety of crystalline structures, known as polymorphs. These polymorphs exhibit different physical and chemical properties, making them suitable for various applications.
Schreyerite is a rare mineral that is a member of the pyrochlore group. Its chemical composition is primarily defined by the presence of niobium, titanium, and oxygen, along with other elements in lesser amounts. The mineral is typically found in igneous rocks, particularly those that are rich in niobium and titanium. Schreyerite is of interest to mineralogists and geologists because of its unique properties and its occurrence in specific geological environments.
Vaterite is a mineral form of calcium carbonate (CaCO₃) that is less common than other polymorphs of calcium carbonate, such as calcite and aragonite. It is named after the German mineralogist Heinrich Vater. Vaterite typically forms in the presence of certain biological processes, in alkaline conditions, or in the presence of organic compounds.
Continuous \( q \)-Legendre polynomials are a family of orthogonal polynomials that extend classical Legendre polynomials into the realm of \( q \)-calculus. They arise in various areas of mathematics and physics, particularly in the study of orthogonal functions, approximation theory, and in the context of quantum groups and \( q \)-series.
Hudde's Rules refer to a set of guidelines used in organic chemistry for determining the stability of reaction intermediates, particularly carbocations and carbanions. These rules help predict the relative reactivity and stability of different carbocation species based on their structure and the substituents attached to them.
Boas–Buck polynomials are a family of orthogonal polynomials that arise in the study of polynomial approximation theory. They are named after mathematicians Harold P. Boas and Larry Buck, who introduced them in the context of approximating functions on the unit disk. These polynomials can be defined using a specific recursion relation, or equivalently, they can be described using their generating functions.
The dual q-Krawtchouk polynomials are a family of orthogonal polynomials associated with the discrete probability distributions arising from the q-analog of the Krawtchouk polynomials. These polynomials arise in various areas of mathematics and have applications in combinatorics, statistical mechanics, and quantum groups. The Krawtchouk polynomials themselves are defined in terms of binomial coefficients and arise in the study of discrete distributions, particularly with respect to the binomial distribution.
Generalized Appell polynomials are a family of orthogonal polynomials that generalize the classical Appell polynomials. Appell polynomials are a set of polynomials \(A_n(x)\) such that the \(n\)-th polynomial can be defined via a generating function or a differential equation relationship. Specifically, Appell polynomials satisfy the condition: \[ A_n'(x) = n A_{n-1}(x) \] with a given initial condition.
Geronimus polynomials are a class of orthogonal polynomials that arise in the context of discrete orthogonal polynomial theory. They are named after the mathematician M. Geronimus, who contributed to the theory of orthogonal polynomials. Geronimus polynomials can be defined as a modification of the classical orthogonal polynomials, such as Hermite, Laguerre, or Jacobi polynomials.
Peters polynomials are a sequence of orthogonal polynomials associated with the theory of orthogonal functions and are specifically related to the study of function approximation and interpolation. They can be regarded as a specific case of orthogonal polynomials on specific intervals or with certain weights. While "Peters polynomials" might not be as widely referenced as, say, Legendre or Chebyshev polynomials, they represent an interesting area of study within numerical analysis and mathematical approximation.
Quantum philosophy is an area of philosophical inquiry that explores the implications and foundations of quantum mechanics, which is the branch of physics that deals with the behavior of matter and energy on very small scales, such as atoms and subatomic particles. This field of philosophy addresses several deep questions regarding the nature of reality, observation, and knowledge, and it often intersects with issues in metaphysics, epistemology, and the philosophy of science.

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.
