The chelate effect is the greater affinity of chelating ligands for a metal ion than that of similar nonchelating (monodentate) ligands for the same metal. The thermodynamic principles underpinning the chelate effect are illustrated by the contrasting affinities of copper (II) for ethylenediamine (en) vs. methylamine .
"BLIT" (acronym of Berryman Logical Image Technique) is a 1988 science fiction short story by the British writer David Langford. It takes place in a setting where highly dangerous types of images called "basilisks" (after the legendary reptile) have been discovered; these images contain patterns within them that exploit flaws in the structure of the human mind to produce a lethal reaction ...
Holography served as an inspiration for many video games with the science fiction elements. In many titles, fictional holographic technology has been used to reflect real life misrepresentations of potential military use of holograms, such as the "mirage tanks" in Command & Conquer: Red Alert 2 that can disguise themselves as trees.

The eluviation of chelate compounds is the downward movement of soil chelates. The eluviation of chelate compounds can be affected by: Acidity. Organic acids produced under acidic conditions can increase the solubility of metal elements such as iron and aluminum, thereby enhancing soil eluviation. Iron and aluminum are easily leached at low pH.
The late 19th century witnessed a new generation of writers, such as J.-H. Rosny aîné, utilizing science and pseudoscience for purely fictional purposes. [15] This marked a significant departure from their predecessors, who employed the conjectural element as a pretext, following in the footsteps of Savinian Cyrano de Bergerac's utopian, Jonathan Swift's satires, and Camille Flammarion's ...
Science fiction genre – while science fiction is a genre of fiction, a science fiction genre is a subgenre within science fiction. Science fiction may be divided along any number of overlapping axes. Gary K. Wolfe's Critical Terms for Science Fiction and Fantasy identifies over 30 subdivisions of science fiction, not including science fantasy ...
The macrocyclic effect is the high affinity of metal cations for macrocyclic ligands, compared to their acyclic analogues. [7] [8] The high affinity of macrocyclic ligands is thought to be a combination of the entropic effect seen in the chelate effect, together with an additional energetic contribution that comes from the preorganized nature of the ligating groups (that is, no additional ...
Boris Karloff in James Whale's 1931 film Frankenstein, based on Mary Shelley's 1818 novel.The monster is created by an unorthodox biology experiment.. Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of ...
