2. Iron poisoning - Wikipedia

   en.wikipedia.org/wiki/Iron_poisoning

   Iron poisoning typically occurs from ingestion of excess iron that results in acute toxicity. Mild symptoms which occur within hours include vomiting, diarrhea, abdominal pain, and drowsiness. [ 1] In more severe cases, symptoms can include tachypnea, low blood pressure, seizures, or coma. [ 2] If left untreated, iron poisoning can lead to ...

3. Air ioniser - Wikipedia

   en.wikipedia.org/wiki/Air_ioniser

   An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in ...

4. Iron-oxidizing bacteria - Wikipedia

   en.wikipedia.org/wiki/Iron-oxidizing_bacteria

   The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...

7. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings.

8. Rust - Wikipedia

   en.wikipedia.org/wiki/Rust

   Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron (III) oxides (Fe 2 O 3 ·nH 2 O) and iron (III) oxide-hydroxide (FeO (OH), Fe (OH) 3 ), and is typically associated with the corrosion of refined iron .

9. Medical uses of silver - Wikipedia

   en.wikipedia.org/wiki/Medical_uses_of_silver

   The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. [2] [3] [4] Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. [5] [6] [7] The limited evidence available shows that silver coatings on endotracheal breathing tubes ...
