Reversible-deactivation polymerization, often referred to as controlled/living polymerization, is a type of polymerization process that enables the synthesis of polymers with well-defined molecular weights and narrow molecular weight distributions. This technique allows for a high degree of control over the polymerization process, enabling the production of polymers with specific structural features and functionalities. The key characteristic of reversible-deactivation polymerization is the presence of reversible reactions that can temporarily deactivate the active sites of the polymerization process.
Thin film deposition is a process used to create very thin layers of material on a substrate. These layers, typically measuring from a few nanometers to several micrometers in thickness, can be composed of metals, oxides, polymers, or other compounds. Thin films are essential in a variety of applications, including electronics, optics, coatings, and photovoltaics.
Solid-state chemists are scientists who study the synthesis, structure, properties, and behavior of solid materials. This branch of chemistry focuses specifically on solid materials, as opposed to liquids and gases. Solid-state chemistry encompasses a wide range of topics, including: 1. **Crystallography**: The study of the arrangement of atoms within crystals. This involves understanding how atoms pack together in three-dimensional structures and how these structures relate to the material's properties.
The Istituto per le Applicazioni del Calcolo Mauro Picone (IAC) is an Italian research institute affiliated with the National Research Council of Italy (CNR). Founded in 1957 and named after the prominent Italian mathematician Mauro Picone, the institute focuses on various fields of applied mathematics and its applications in science and technology.
Statistical organizations in the United States are institutions that collect, analyze, and disseminate statistical data related to various aspects of the economy, society, and the environment. These organizations play a crucial role in providing reliable data that policymakers, researchers, and the public use to make informed decisions. Here are some key statistical organizations in the U.S.: 1. **U.S.
"Shipping News" can refer to a couple of different concepts depending on the context: 1. **Literature**: "The Shipping News" is a novel by American author E. Annie Proulx, published in 1993. The book centers on Quoyle, a struggling newspaper hack who moves to Newfoundland with his two daughters after the death of his wife.
Power system operations and control refer to the processes and technologies used to ensure the reliability, stability, and efficiency of electrical power systems. This encompasses a variety of activities and strategies designed to manage the generation, transmission, distribution, and consumption of electrical energy. Here are the main components of power system operations and control: ### 1.
An industrial fan is a type of mechanical device designed to move air or gas in various industrial settings. These fans are typically larger and more robust than standard or residential fans and are engineered to handle demanding applications, including ventilation, cooling, drying, and material handling processes. ### Key Features of Industrial Fans: 1. **Durability**: Built to withstand harsh environments, industrial fans are often made from heavy-duty materials like steel or aluminum.
Butt welding is a welding process where two pieces of metal are joined together by heating their edges until they reach a molten state and then allowing them to cool and solidify, forming a strong bond. This method is commonly used for joining metal components that are aligned edge-to-edge. There are several key aspects of butt welding: 1. **Preparation**: The edges of the materials to be joined are typically prepared to ensure proper alignment and fit.
Friction Hydro Pillar Processing (FHPP) is a manufacturing technique primarily used to produce high-strength, lightweight components, often in the aerospace, automotive, and energy sectors. It involves the use of a combination of friction welding and hydroforming techniques. Here's a brief overview of the process: 1. **Friction Welding**: In this initial stage, two metal pieces are joined together through frictional heating.
Laser-hybrid welding is an advanced welding technique that combines the benefits of both laser welding and traditional arc welding processes, such as MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding. This hybrid approach leverages the focused energy of a laser beam along with the heat generated by the arc to achieve efficient and versatile welding solutions.
Micellar cubic structures refer to a particular arrangement of surfactant molecules that form a three-dimensional cubic phase in solutions, often in the context of self-assembled structures. These structures are notable in colloidal and materials science due to their unique properties and potential applications in pharmaceuticals, food science, and nanotechnology. In a micellar cubic phase, surfactant molecules aggregate in a way that creates a repeating cubic lattice structure.
C. V. Boys (Cecil V. Boys) is a name that may refer to a notable British physicist known for his contributions to experimental physics, particularly in the field of fluid dynamics and aerodynamics. He is also known for his work on the behavior of fluids and the principles of fluid mechanics. In a different context, "C. V.
Emil Martinec is a theoretical physicist known for his work in the fields of cosmology, gravity, and string theory. He has contributed to various research areas, including the study of black holes, gravitational waves, and the early universe. Martinec's work often involves advanced mathematical formulations and theoretical models that help to deepen our understanding of fundamental physical concepts.
Menas Kafatos is a prominent physicist and cosmologist known for his work in the fields of quantum physics, consciousness, and the philosophical implications of scientific understanding. He has authored numerous research papers and books, often focusing on topics such as the relationship between science and spirituality, the nature of reality, and the implications of quantum mechanics. Kafatos has held academic positions at various institutions and has been involved in interdisciplinary studies that bridge the gap between science and philosophy.
Nicholas P. Samios is a physicist known for his work in the field of nuclear and particle physics. He has been involved in various research projects and has contributed to scientific literature, particularly in areas related to nuclear reactions and high-energy physics. However, specific details about his current affiliations or recent research may not be widely publicized.
PIKO can refer to different things depending on the context, including: 1. **PIKO (Company)**: A well-known manufacturer of model trains and railway accessories, particularly in the hobbyist and collectors' markets. They produce a wide range of products in various scales, including N scale and HO scale. 2. **PIKO (Programming Language)**: PIKO is also the name of a simple programming language used primarily for educational purposes.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
