Ion channels are pore-forming membrane proteins that allow ions to pass through the channel pore. Their functions include establishing a resting membrane potential, shaping action potentials and other electrical signals by gating the flow of ions across the cell membrane, controlling the flow of ions across secretory and epithelial cells, and regulating cell volume. Ion channels are present in the membranes of all excitable cells. Ion channels are one of the two classes of ionophoric proteins, the other being ion transporters.
In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research.
Academic publishing is the subfield of publishing which distributes academic research and scholarship. Most academic work is published in academic journal article, book or thesis form. The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called "grey literature". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field.
An academic or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They are usually peer-reviewed or refereed. Content typically takes the form of articles presenting original research, review articles, and book reviews. The purpose of an academic journal, according to Henry Oldenburg, is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge, and perfecting all Philosophical Arts, and Sciences."
Physical Review is an American peer-reviewed scientific journal established in 1893 by Edward Nichols. It publishes original research as well as scientific and literature reviews on all aspects of physics. It is published by the American Physical Society (APS). The journal is in its third series, and is split in several sub-journals each covering a particular field of physics. It has a sister journal, Physical Review Letters, which publishes shorter articles of broader interest.
An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation. Ion-selective electrodes are used in analytical chemistry and biochemical/biophysical research, where measurements of ionic concentration in an aqueous solution are required.
In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface. A more general term is sorption, which covers absorption, adsorption, and ion exchange. Absorption is a condition in which something takes in another substance.
Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic "ion exchangers".
Ion chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids. However, ion chromatography must be done in conditions that are one unit away from the isoelectric point of a protein.
Inner sphere complex is a type of surface complex that refers to the surface chemistry changing a water-surface interface to one without water molecules bridging a ligand to the metal ion. Formation of inner sphere complexes occurs when ions bind directly to the surface with no intervening water molecules. These types of surface complexes are restricted to ions that have a high affinity for surface sites and include specifically adsorbed ions that can bind to the surface through covalent bonding.
The European Geosciences Union (EGU) is a non-profit international union in the fields of Earth, planetary, and space sciences whose vision is to "realise a sustainable and just future for humanity and for the planet." The organisation has headquarters in Munich (Germany). Membership is open to individuals who are professionally engaged in or associated with these fields and related studies, including students and retired seniors.
Sorption is a physical and chemical process by which one substance becomes attached to another. Specific cases of sorption are treated in the following articles:
Journal of Luminescence is a peer-reviewed scientific journal, published monthly.
The Electrochemical Society is a learned society based in the United States that supports scientific inquiry in the field of electrochemistry and solid-state science and technology. The society membership comprises more than 8,000 scientists and engineers in over 70 countries worldwide who hold individual membership, as well as roughly 100 corporations and laboratories that hold corporate membership.
The IEEE Electron Devices Society is a professional society of the IEEE.
Migration Letters is an international triannual (Jan.-May-Sep.) peer-reviewed academic journal of migration studies published by Transnational Press London since 2004. Topics covered range from internal migration to transnational mobility and from voluntary to forced migration. Migration Letters is indexed and abstracted by the International Bibliography of the Social Sciences. Notable contributors to the journal include Ron J. Johnston, Caroline Brettell, Gordon F. De Jong, Philip L. Martin and Thomas Faist.
The Open Access Scholarly Publishers Association (OASPA) is a non-profit trade association representing the interests of open access journal publishers globally in all scientific, technical and scholarly disciplines. Along with promoting open access publishers, OASPA sets best practices and provides a forum for the exchange of information on and experiences of open access. OASPA brings together the major open access publishers on the one hand and independent—often society-based or university-based—publishers on the other, along with some hybrid open access publishers. While having started out with an exclusive focus on open access journals, it is now expanding its activities to include matters pertaining to open access books too.
An article processing charge (APC), also known as a publication fee, is a fee which is sometimes charged to authors to make a work available open access in either an open access journal or hybrid journal. This fee may be paid by the author, the author's institution, or their research funder. Some publishers waive the fee in cases of hardship or geographic location, but this is not a widespread practice. An article processing charge does not guarantee that the author retains copyright to the work, or that it will be made available under a Creative Commons license.
Industrial separation processes are technical procedures which are used in industry to separate a product from impurities or other products. The original mixture may either be a natural resource or the product of a chemical reaction.
An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules.
