Membrane-aerated biofilms with oxygen and nutrients diffusing from the opposite sides possess distinct properties, including the ability to couple aerobic and anaerobic processes. The objective of ...

Chemical oxygen demand (COD) analysis is a pivotal method for evaluating water quality by quantifying the oxygen required to oxidise organic matter. Traditionally, methods have relied on hazardous ...

Salmo gairdneri erythrocytes were lysed and the oxygen-binding properties of the haemolysates in 0.1 M tris-HCl, veronal-HCl, imidazole-HCl and phosphate buffers were determined over the pH range ...

When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.
