Electrocoagulation
The term "electro" refers to the application of electrical charges to water. Electrocoagulation (EC) is an advanced and economical water treatment technology that applies electrical charges to water to remove contaminants. It is an effective process for treating industrial wastewater containing metals, oils, grease, heavy metals, and other pollutants.
The electrocoagulation mechanism resembles chemical coagulation in that cationic species neutralize surface charges. However, the characteristics of the electrocoagulated flock differ significantly from those generated by chemical coagulation. An electrocoagulated flock tends to contain less bound water, is more shear-resistant, and is more readily filterable.
The electrocoagulation process has been used for most of the 20th century, particularly in North America, to treat wastewater from various industries, including pulp and paper, mining, and metal processing. In recent years, it has gained popularity in the United States, South America, and Europe for treating industrial wastewater. Electrocoagulation is not commonly used for domestic wastewater treatment.

Electrochemical
The prefix "electro" in medical terms is derived from the Greek word "ēlektron," which refers to amber, a substance that can generate static electricity through friction. In medicine, electrochemistry has played a significant role in understanding and treating various health conditions.
Electrochemistry is the branch of physical chemistry that explores the relationship between electrical potential differences and identifiable chemical changes. These electrochemical reactions involve the movement of electrons through an electronically conducting phase, often an external electrical circuit. This field was pioneered by Italian physician Luigi Galvani in the late 18th century, who proposed the concept of a "nerve-electrical substance" in biological life forms, which he termed "animal electricity."
In medicine, electrochemical forces are essential for understanding how our bodies function. For example, the membrane theory of nerve excitation, proposed by Julius Bernstein in 1902, explains how the membranes of neurons can become electrically polarized by blocking or transmitting specific ions. This polarization triggers the release of acetylcholine, causing adjacent neurons to become polarized and sending impulses throughout the body.
Additionally, electrochemistry has been applied in medicine through the use of recording devices that convert the body's natural electrical activity into diagrams for medical analysis. Physicians utilize electrocardiograms (ECGs) to diagnose heart abnormalities, electroencephalograms (EEGs) for brain disturbances, and electromyograms (EMGs) to detect loss of nerve function.
Furthermore, electrochemical cells, consisting of two half-cells with electrodes dipped in an electrolyte, play a crucial role in energy generation and storage. These cells can be Galvanic or electrolytic, with the former generating electrical energy from chemical reactions and the latter facilitating chemical reactions using supplied electrical energy.

Electrolysis
The prefix "electro" in medical terms refers to electricity or electric. Electrolysis is a hair removal treatment that uses electricity to destroy hair follicles and prevent hair growth. It has been used for over 100 years and is considered very safe, with only slight risks of infection or scarring if the procedure is not performed correctly.
During the procedure, a trained electrologist inserts a thin wire or needle into the hair follicle under the skin's surface. An electric current then travels down the wire to the bottom of the follicle, destroying the hair root. This process can be used to treat most areas of the body, including the face, bikini line, thighs, lower legs, breasts, abdomen, fingers, and toes. It is effective for sensitive areas and works with a wide range of skin and hair types.
The hair follicle is responsible for producing hair and shedding it through a cycle of growth, rest, and replacement. Electrolysis aims to catch the hairs at the right point in this cycle to destroy them. Each treatment lasts between 15 minutes and one hour, and multiple treatments are usually needed to achieve permanent hair removal.
After the treatment, it is recommended to avoid activities that may irritate the hair follicles for the first 24 hours, such as sweating, sun exposure, or applying makeup. Some people may experience temporary skin reddening or, in the case of darker skin tones, temporary dark spots that fade over time. Overall, electrolysis is a safe and effective method for permanent hair removal, with the main disadvantage being the length of time required to achieve desired results.

Electrogastrogram
The prefix "electro-" in medical terms refers to electricity or electric.
An electrogastrogram (EGG) is a graphic produced by electrogastrography, a non-invasive diagnostic technique that detects, analyses, and records the myoelectrical signals generated by the movement of smooth muscles in the stomach, intestines, and other smooth muscle-containing organs. In other words, it measures the electrical activity that prompts the muscles to squeeze and release, known as peristalsis. This procedure can help determine if abnormal electrical activity is causing nausea, vomiting, or abdominal pain.
The EGG was first introduced in 1922 by Alvarez, who also pioneered early studies of electrogastrography in 1921-22. It was then rediscovered in 1957 and gained popularity in the 1990s. The non-invasive nature of EGG has made it attractive to researchers and clinicians, but it has also sparked controversies regarding its validity and applications.
The recording of an EGG can be made from the gastrointestinal surface mucosa, serosa, or the external skin surface. The cutaneous electrogastrography provides an indirect representation of the electrical activity, and it is often used due to its ease of performance. The EGG is similar in principle to an electrocardiogram (ECG), which detects muscular activity in various regions of the heart. However, the EGG focuses on detecting the myoelectrical activity of wave-like contractions in the gastrointestinal tract.
Psychologists have recently used the EGG to test physiological arousal, specifically studying the increase in bradygastria, which is when electrical activity in the stomach drops below 2 cpm, resulting in a slower stomach rhythm when exposed to disgusting stimuli. This abnormal myoelectrical activity is often combined with other precursors to nausea and vomiting.

Electronegative
The prefix "electro" in medical terms is associated with electricity or electric. For instance, the word "electrocardiogram" refers to a device that records the electrical activity of the heart.
Now, onto the word "electronegative", which is a term used in chemistry. It refers to the tendency of an atom in a molecule to attract the shared pair of electrons towards itself. This property is known as electronegativity. It is a dimensionless property, meaning it only indicates a tendency, and it is measured on several scales, with the most commonly used one designed by Linus Pauling. This scale, known as the Pauling scale, runs from 0.79 (for the least electronegative element, cesium) to 3.98 or 4.0 (for the most electronegative element, fluorine).
Electronegativity is important in understanding the strength of covalent bonds between atoms. When two atoms with different electronegativities form a bond, the more electronegative atom pulls the shared electrons closer to itself, developing a partially negative charge (𝛿-). At the same time, the less electronegative atom develops a partial positive charge (𝛿+). This phenomenon is known as polarized bonding.
The electronegativity of an atom is influenced by factors such as the nuclear charge (the number of protons) and the number and arrangement of other electrons in the atomic shells. As you move across a period in the periodic table from left to right, the nuclear charge increases, and the atomic size decreases, resulting in an increase in electronegativity. On the other hand, as you move down a group, the nuclear charge increases, but this is offset by the addition of one shell, leading to a decrease in electronegativity.
In organic chemistry, electronegativity is often associated with functional groups rather than individual atoms, and the terms "group electronegativity" and "substituent electronegativity" are used interchangeably. Additionally, it is important to distinguish between the inductive effect and the resonance effect, which are sometimes referred to as σ- and π-electronegativities, respectively.
