These materials have garnered significant interest in recent years due to their unique properties and potential applications in areas such as spintronics, quantum computing, and magnetic sensors.

Neodymium magnets, also known as NdFeB magnets, are a type of rare-earth magnet made from an alloy of neodymium, iron, and boron. These magnets are known for their exceptional strength and are among the most powerful permanent magnets available today. Here are some key features and characteristics of neodymium magnets: 1. **Composition**: The main components of neodymium magnets are neodymium (Nd), iron (Fe), and boron (B).

Rare-earth magnets are a type of powerful permanent magnet made from alloys of rare-earth elements. The two most common types of rare-earth magnets are neodymium magnets (NdFeB) and samarium-cobalt magnets (SmCo). 1. **Neodymium Magnets (NdFeB)**: - These are the most widely used type of rare-earth magnets. They are made from an alloy of neodymium, iron, and boron (Nd2Fe14B).

Quasielastic scattering is a process in particle physics and nuclear physics in which a projectile particle (such as a neutron or a charged particle) collides with a target nucleus, leading to the ejection of one or more particles from the nucleus while the overall energy and momentum are conserved.

Vicalloy is a registered trademark for a specific line of alloys that are mainly used in the production of magnets, particularly in applications requiring high magnetic performance. These alloys typically consist of iron, cobalt, nickel, and other elements that enhance their magnetic properties. Vicalloy is known for its ability to maintain strong magnetic characteristics even at elevated temperatures, making it suitable for various industrial applications, including motors, sensors, and other electromagnetic devices.

Cunife is an alloy primarily made of copper, nickel, and iron, though the specific composition can vary depending on the application. The name "Cunife" is a trademark which is often used to refer to this type of alloy. It is known for its excellent magnetic properties and is commonly used in applications that require good electrical conductivity and resistance to corrosion.

A supersolid is a state of matter that exhibits properties of both solids and superfluids. In a supersolid, the material has a crystalline structure, which is characteristic of solids, but it also exhibits superfluid-like behavior, such as the ability to flow without viscosity. This fascinating phase of matter combines the rigidity of a solid with the frictionless flow of a superfluid, allowing it to display unique and counterintuitive characteristics.

ANSI C12.19 is a standard developed by the American National Standards Institute (ANSI) for data model and communication protocols in the context of electric metering systems. Specifically, it provides guidelines for the structure, format, and interpretation of data and communication methods used by utility companies and meter manufacturers for electrical usage data. The standard focuses on ensuring interoperability between different devices and systems used for metering electric power.

The ENEC Mark stands for "European Norms Electrical Certification." It is a certification mark that indicates compliance with European safety and performance standards for electrical products. The mark is recognized throughout Europe and signifies that the product has been rigorously tested and meets the required European norms for safety, performance, and compatibility. Products bearing the ENEC Mark are deemed safe for use and reliable, and this certification helps manufacturers, importers, and consumers ensure that electrical products adhere to regulated standards.

Mains electricity specifications vary significantly around the world. Here is a summary of the mains electricity standards in various countries concerning voltage, frequency, and plug types: ### Voltage and Frequency - **North America (e.g., USA, Canada)**: - **Voltage:** 120V - **Frequency:** 60Hz - **Most of Europe (e.g.

Mains power connectors, often referred to as power connectors or AC power connectors, are electrical components used to connect electrical devices to the mains electricity supply. These connectors allow equipment to draw power from the electrical grid, facilitating the operation of household appliances, electronics, and industrial machinery. Mains power connectors come in various shapes and sizes, depending on regional standards, voltage, and current specifications. Here are some common types: 1. **IEC Connectors (C13, C14, etc.

The Zandkreekdam is a dam located in the Netherlands, part of the Delta Works, a series of projects designed to protect the country from flooding. Specifically, the Zandkreekdam is situated in the province of Zeeland and serves both as a barrier against the North Sea and as a means to regulate water levels in the area.

Industrial and multiphase power plugs and sockets are specialized electrical connectors designed for high-power applications typically found in industrial, commercial, and agricultural settings. Here's a breakdown of each term: ### Industrial Power Plugs and Sockets **Definition**: - Industrial power plugs and sockets are robust electrical connectors used to safely connect larger equipment or machinery to a power supply.

Knob-and-tube wiring is an early method of electrical wiring used in buildings, primarily from the late 19th century to the early 20th century. This system consists of individual wires that are run through ceramic insulators mounted on wooden knobs (the "knob" part) and secured with straps or staples. The wires are typically insulated with rubber or cloth, and they run through walls, ceilings, and floors to distribute electrical power.

The National Electrical Contractors Association (NECA) is a trade association in the United States that represents electrical contractors and the electrical industry as a whole. Founded in 1901, NECA's mission is to promote the growth and success of its members through advocacy, education, technical support, and the development of industry standards.

CACNB2 is a gene that encodes the beta-2 subunit of voltage-dependent calcium channels. These calcium channels are integral membrane proteins that play a crucial role in the regulation of calcium ion (Ca²⁺) influx into cells, which is essential for various physiological processes, including muscle contraction, neurotransmitter release, and hormone secretion.
