Pheromone biosynthesis activating neuropeptide The pheromone biosynthesis activation neuropeptide (PBAN) is a neurohormone (member of the PBAN/pyrokinin neuropeptide family) that activates the biosynthesis of pheromones in moths. Female moths release PBAN into their hemolymph during the scotophase to stimulate the bios... | https://en.wikipedia.org/wiki?curid=30280355 |
Structure of liquids and glasses The structure of liquids, glasses and other non-crystalline solids is characterized by the absence of long-range order which defines crystalline materials. Liquids and amorphous solids do, however, possess a rich and varied array of short to medium range order, which originates from che... | https://en.wikipedia.org/wiki?curid=30283480 |
Structure of liquids and glasses A typical plot of "g" versus "r" of a liquid or glass shows a number of key features: The static structure factor, "S(q)", which can be measured with diffraction techniques, is related to its corresponding "g(r)" by Fourier transformation where "q" is the magnitude of the momentum trans... | https://en.wikipedia.org/wiki?curid=30283480 |
Structure of liquids and glasses Once obtained, an "S(q)" pattern can be Fourier transformed to provide a corresponding radial distribution function (or pair correlation function), denoted in this article as "g(r)". For an isotropic material, the relation between "S(q)" and its corresponding "g(r)" is The "g(r)", which... | https://en.wikipedia.org/wiki?curid=30283480 |
Structure of liquids and glasses Other experimental techniques often employed to study the structure of glasses include Nuclear Magnetic Resonance (NMR), X-ray absorption fine structure (XAFS) and other spectroscopy methods including Raman spectroscopy. Experimental measurements can be combined with computer simulation... | https://en.wikipedia.org/wiki?curid=30283480 |
Structure of liquids and glasses every silicon atom is coordinated by 4 oxygen atoms and the nearest neighbour Si-O bond length exhibits only a narrow distribution throughout the structure. The tetrahedra in silica also form a network of ring structures which leads to ordering on more intermediate length scales of up t... | https://en.wikipedia.org/wiki?curid=30283480 |
