Chemistry and materials science Polymorphism is also observed in chemistry and materials science, and it has important implications for numerous areas, including agrochemicals, medicines, foods, pigments and even explosives. In all these areas, polymorphism refers to the idea that a material or chemical...

Robin K.Harris, inEncyclopedia of Spectroscopy and Spectrometry (Second Edition), 2010 Introduction Polymorphismis a very widespread phenomenon inchemistry. It commonly occurs in both organic andinorganic chemistryand inmineralogy, and is also found for polymers andbiochemicals. However, it is not strai...

Here we illustrate trends in the crystal chemistry of the n -alkylammonium halides, and the investigative methods, using as examples n -octadecylammonium chloride,C 18 H 37 NH + 3 Cl 鈥 , and their related bromides and iodidesdoi:10.1007/978-1-4020-5941-4_10Gert J. Kruger...
Förster resonance energy transfer (FRET) provides nanometer-scale distance information by measuring the excitation energy transfer between two dyes (donor and acceptor) attached to specific sites in a protein via specific chemistry. Single-molecule FRET (smFRET) can resolve the structural and dynamic...
The distribution of bill sizes within regional populations of kites is correlated strongly with the sizes of terrestrial snails found in the region. Except for cases of sexual dimorphism, there are few, if any, other examples of a morphometric triat being polymorphic in birds. The ecological, ...
Color polymorphism is an interesting property of chemical systems which present crystal polymorphs of different colors. It is a rare phenomenon, with only a few examples reported in the literature hitherto. Nevertheless, systems exhibiting color polymorp
Malaria, a major killer in human societies, is one of the best examples to illustrate this phenomenon. The parasite (Plasmodium) is transmitted to humans through the bites of mosquitoes of the genus Anopheles and develops its deleterious effects by infecting red blood cells (erythrocytes). ...
