This field encompasses a variety of techniques and technologies for the production, manipulation, and recycling of plastics. Plastics engineers work to develop new plastic materials and enhance existing ones for various applications across several industries, including automotive, packaging, consumer goods, medical devices, and electronics.
A pugmill, also known as a pug mill or pug mixer, is a type of industrial mixer used to blend and mix materials, particularly in the production of clay, ceramics, and other similar substances. It is specifically designed to process materials that must be mixed in a wet state or require the addition of water to achieve the desired consistency.
Severe Plastic Deformation (SPD) refers to a set of advanced processing techniques used to significantly improve the mechanical properties of materials, particularly metals, through large strains without a significant increase in temperature. The main objective of SPD is to refine the microstructure of the material, leading to a high density of dislocations and a fine-grained structure, which ultimately enhances strength, hardness, ductility, and other properties.
Poly(amidoamine), commonly referred to as PAMAM, is a type of dendritic polymer that is characterized by its branched structure. It is a synthetic polymer that comprises a central core atom (often a nitrogen atom) from which multiple amidoamine branches extend. PAMAM is produced through iterative processes of reactions involving amines and acids, allowing for the precise control of the polymer's architecture, including its size and functionalization.
Polymer adsorption refers to the process by which polymer molecules adhere to a solid surface or interface, often involving a liquid, gas, or another solid medium. This phenomenon can occur in various contexts, including biological systems, materials science, and industrial applications.
A powder mixture refers to a composition made by blending two or more powdered materials. These materials can vary widely in their chemical and physical properties and can include metals, ceramics, polymers, or other substances. Powder mixtures are commonly used in various industries, including pharmaceuticals, food, ceramics, and materials science. Key points about powder mixtures include: 1. **Composition**: The individual components can have different particle sizes, shapes, and chemical properties.
Retrogression heat treatment is a specialized thermal processing technique primarily used on certain aluminum alloys, especially those in the 2xxx and 7xxx series, which are heat-treatable alloys. The goal of retrogression is to enhance the mechanical properties of the aluminum, such as strength and toughness, by modifying the microstructure. ### Process Overview 1.
Random Sequential Adsorption (RSA) is a theoretical model used to describe the process of particle deposition onto a surface. In this model, particles are randomly placed on a surface one at a time. Each particle is allowed to "adsorb" or stick to the surface only if it does not overlap with any already adsorbed particles. Once a particle is successfully adsorbed, it stays on the surface, and subsequent particles are added under the same condition of non-overlapping.
Thiomer is a term that is often associated with a specific class of pharmaceutical compounds known as thiomers or thiolated polymers. These compounds are typically modified polymers that have thiol (-SH) groups incorporated into their structure. Thiomers are researched for various applications, particularly in drug delivery systems, due to their unique properties such as enhanced stability, biocompatibility, and the ability to form strong interactions with biological components.
Materials Research Innovations is a peer-reviewed scientific journal that focuses on the field of materials science. It publishes research articles, reviews, and communications covering a broad range of topics related to the development, characterization, and application of new materials. This includes areas such as nanomaterials, polymers, ceramics, metals, and composites. The journal serves as a platform for researchers to share their findings, innovations, and methodologies in materials research, promoting advancements in technology and applications across various industries.
Materials Research Letters is a scholarly journal that publishes research articles, letters, and reviews focusing on materials science and engineering. The journal primarily aims to disseminate high-quality, cutting-edge research findings in the area of materials, encompassing various fields such as nanomaterials, biomaterials, polymers, ceramics, metals, and composites. The format of the publication often allows for rapid dissemination of research results, which is suitable for researchers looking to share significant findings quickly.
Reaction bonded silicon carbide (RBSC) is a type of advanced ceramic material known for its excellent mechanical properties, thermal stability, and resistance to chemical attack. It is produced through a process that involves the reaction of silicon with carbon at high temperatures, which results in the formation of silicon carbide (SiC).
Redux is a predictable state management library for JavaScript applications, often used with frameworks like React. It provides a centralized store to manage the application's state in a way that is easier to understand and debug. Redux follows a unidirectional data flow and uses actions to describe state changes, reducers to update the state, and a store to hold the application state. The term "adhesive" in relation to Redux is not commonly recognized or associated directly with the library itself.
"Smart cut" can refer to several different concepts depending on the context, including technology, video editing, or even a feature in a specific software application. Here are a few interpretations: 1. **Video Editing**: In video editing software, a "smart cut" may refer to a feature that intelligently cuts and trims footage based on audio cues, scene changes, or content analysis to create a more polished final video.
B mesons are a type of meson that contain a bottom quark (b quark) and an anti-quark. Mesons are subatomic particles made up of one quark and one antiquark, and they are part of the family of hadrons, which are particles affected by the strong force. B mesons come in several varieties, depending on the type of anti-quark they pair with the bottom quark.
The BaBar experiment is a particle physics project that was conducted at the SLAC National Accelerator Laboratory in California, USA, primarily between 1999 and 2008. The experiment's main goal was to investigate the properties of B mesons, which are pairs of bottom (or beauty) quarks and their corresponding antiquarks.
Reinforced concrete is a composite material that combines concrete with reinforcement, typically in the form of steel bars (rebar) or mesh. The primary purpose of adding reinforcement is to improve the tensile strength of concrete, which is strong in compression but weak in tension. This combination allows reinforced concrete to withstand various types of loads and stresses more effectively than plain concrete.

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.
