Artipoppe was founded by Anna van den Bogert and inspired by her experience of motherhood and search for functional yet stylistically elevated baby carriers. [5] From 2012 to 2018, the brand produced baby wraps and ring slings, expanding in 2018 with the Zeitgeist Baby Carrier, all recognized by the International Hip Dysplasia Institute for being “hip-healthy.” [6] Artipoppe's philosophy ...
Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.
Carrier mobility strongly depends on the concentration of localized states in a non-linear fashion. [2] In the case of nearest-neighbour hopping , which is the limit of low concentrations, the following expression can be fitted to the experimental results: [ 3 ]
Carrier and channel ionophores (a) Carrier ionophores reversibly bind ions and carry them through cell membranes. (b) Channel ionophores create channels within cell membranes to facilitate the transport of ions. In chemistry, an ionophore (from Greek ion and -phore ' ion carrier ') is a chemical species that reversibly binds ions. [1]
Lipid-based carriers include both liposomes and micelles. Examples of gold nanoparticles are gold nanoshells and nanocages . [ 3 ] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [ 5 ]
An electron transport chain (ETC [1]) is a series of protein complexes and other molecules which transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H + ions) across a membrane.
Facilitated diffusion in cell membrane, showing ion channels and carrier proteins. Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins. [1]
Uniporter carrier proteins work by binding to one molecule or substrate at a time. Uniporter channels open in response to a stimulus and allow the free flow of specific molecules. [2] There are several ways in which the opening of uniporter channels may be regulated: Voltage – Regulated by the difference in voltage across the membrane
