In condensed-matter physics, channelling (or channeling) is the process that constrains the path of a charged particle in a crystalline solid. [1] [2] [3]Many physical phenomena can occur when a charged particle is incident upon a solid target, e.g., elastic scattering, inelastic energy-loss processes, secondary-electron emission, electromagnetic radiation, nuclear reactions, etc.
Metabolite channeling [1] is the passing of the intermediary metabolic product of one enzyme directly to another enzyme or active site without its release into solution. When several consecutive enzymes of a metabolic pathway channel substrates between themselves, [2] this is called a metabolon. [3]

She started making science videos while working as a mobile app developer at General Electric. [11] She started her channel Physics Girl on October 21, 2011. [12] In an interview with Grant Sanderson, she said that some of the earlier videos were later deleted from the channel. [9] Cowern has also participated in various events as a speaker.
The two-pore-domain or tandem pore domain potassium channels are a family of 15 members that form what is known as leak channels which possess Goldman-Hodgkin-Katz (open) rectification. [1] These channels are regulated by several mechanisms including signaling lipids , oxygen tension , pH , mechanical stretch , and G-proteins . [ 2 ]
The channel has received a smaller grant from the John Templeton Foundation. [ 30 ] In a January 2023 statement, [ 29 ] Kurzgesagt stated that 65% of their income from 2020 to 2022 came from viewers via the sale of merchandise from their shop, such as mugs , posters and toys , crowdfunding via Patreon , and Google AdSense revenue, with ...
Membrane channels are a family of biological membrane proteins which allow the passive movement of ions (ion channels), water or other solutes to passively pass through the membrane down their electrochemical gradient. They are studied using a range of channelomics experimental and mathematical techniques.
Dynamical properties of reaction networks were studied in chemistry and physics after the invention of the law of mass action.The essential steps in this study were introduction of detailed balance for the complex chemical reactions by Rudolf Wegscheider (1901), [1] development of the quantitative theory of chemical chain reactions by Nikolay Semyonov (1934), [2] development of kinetics of ...
