A schematic representation of Clark's 1962 invention, the Oxygen Electrode. The Clark electrode [1] [2] is an electrode that measures ambient oxygen partial pressure in a liquid using a catalytic platinum surface according to the net reaction: [3]
A Geissler tube is composed of a sealed glass cylinder of various shapes, which is partially evacuated and equipped with a metal electrode at each end. It contains rarefied gases—such as neon or argon , air , mercury vapor, or other conductive substances, and sometimes ionizable minerals or metals like sodium .
A MAQUET hollow fiber membrane oxygenator. A membrane oxygenator is a device used to add oxygen to, and remove carbon dioxide from the blood.It can be used in two principal modes: to imitate the function of the lungs in cardiopulmonary bypass (CPB), and to oxygenate blood in longer term life support, termed extracorporeal membrane oxygenation (ECMO).
The blood–air barrier or air–blood barrier, (alveolar–capillary barrier or membrane) exists in the gas exchanging region of the lungs. It exists to prevent air bubbles from forming in the blood , and from blood entering the alveoli .
Additionally, some tubes contain additives that preserve certain components of or substances within the blood, such as glucose. When a tube is centrifuged , the materials within are separated by density, with the blood cells sinking to the bottom and the plasma or serum accumulating at the top.
Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
"President Biden got it absolutely wrong and created a lot of pain here in Northeastern Pennsylvania," Gov. Josh Shapiro said after President Joe Biden's commutation of a judge in Pennsylvania's ...
The electroless deposition and electroplating bath actively performs cathodic and anodic reactions at the surface of the substrate. [2] [3] The standard electrode potential of the metal and reducing agent are important as a driving force for electron exchange. [3] The standard potential is defined as the power of reduction of compounds.
