Nickel(III) oxide, also known as nickel trioxide, is a chemical compound with the formula Ni₂O₃. It is an oxide of nickel in which nickel has an oxidation state of +3. This compound is characterized by its dark green to black appearance and is less common than the more stable Nickel(II) oxide (NiO). Nickel(III) oxide can be produced through various methods, including the oxidation of nickel compounds at high temperatures or through specific chemical reactions.

Mixed potential theory is a concept used primarily in electrochemistry to describe the behavior of electrochemical systems under various conditions. The theory provides a framework for understanding and predicting the potentials and reaction rates in systems where multiple redox reactions may occur simultaneously. ### Key Aspects of Mixed Potential Theory: 1. **Mixed Potential**: In a system with more than one electrochemical reaction, the overall potential is influenced by the contributions from all the involved reactions.

The International Society of Electrochemistry (ISE) is a professional organization dedicated to the advancement and promotion of electrochemical science and technology. Founded in 1949, the ISE serves as a platform for researchers, educators, and professionals in the field of electrochemistry to share knowledge, collaborate on research, and disseminate new findings. The society organizes events, including annual meetings and symposia, where members can present their research, attend lectures, and network with other professionals.

Nikolai Yefimov is not a widely recognized figure in mainstream culture, history, or current events as of my last update in October 2023. It’s possible that he could refer to a lesser-known individual, a fictional character, or someone who has gained recognition after that date.

Internal oxidation is a process that occurs in certain metals and alloys, particularly those that contain reactive elements such as aluminum or silicon. It involves the oxidation of the metal at or within its grain boundaries or internal structures rather than just on the surface. This can happen when the metal is exposed to an oxidizing environment, usually at elevated temperatures. In internal oxidation, oxygen or other oxidizing agents penetrate into the material, leading to the formation of oxides within the metal rather than a mere surface oxidation layer.

SGML predecessor.

As of my last knowledge update in October 2021, there isn't any widely recognized figure or concept by the name "Nikolai Ardelyan." It's possible that you are referring to a lesser-known individual or a character from a specific work of fiction, or it could be a recent development that emerged after my last update.

The short circuit ratio (SCR) of a synchronous generator is a key parameter that offers insight into the machine's ability to handle short-circuit conditions. It is defined as the ratio of the field current required to produce rated voltage (at rated speed and frequency) to the field current required to produce the same terminal voltage under short-circuit conditions.

Squegging is a term that has emerged to describe the practice of using a squeeze ball or "squegg," which is a small, portable, and often stress-relieving device. While the specific attributes and uses of "Squegging" may vary, it generally pertains to utilizing these types of tools for physical exercise, stress relief, or rehabilitation purposes. It's important to note that concepts and trends can evolve quickly, so definitions may vary based on context.

After-rust is a term that is often used in the context of certain forms of art and design, particularly referring to a creative movement or aesthetic focus that deals with the themes of decay and the transformative qualities of materials. It's not a universally defined term, but similar concepts can be found in contemporary art and design.

Amalgamated Zinc, often referred to simply as Amalgamated Zinc Ltd (AZL), was a major mining company in Australia, primarily known for its production of zinc and lead. The company was involved in various mining operations, including the mining, smelting, and refining of zinc and lead ores.

An anion-exchange membrane is a type of semi-permeable membrane that is designed to selectively allow anions (negatively charged ions) to pass through while blocking cations (positively charged ions). These membranes are typically composed of polymer materials that are chemically modified to contain positively charged functional groups, which attract and hold anions in the surrounding solution.

An antimony electrode is an electrochemical sensor typically used for measuring the concentration of specific ions, particularly in the field of analytical chemistry. It is commonly utilized in conjunction with ion-selective electrodes (ISEs) and potentiometric measurements. ### Characteristics 1. **Material Composition**: The electrode is made from antimony, a semimetal that exhibits specific electrochemical properties.

Literally: East of the Mountain.

The Betts electrolytic process, also known as the Betts method, is an electrolytic refining process used primarily for the extraction and purification of lead. It was developed by the American engineer, chemist, and inventor William Betts in the early 20th century.
