Scientists have recently found that the hard shells of diatoms have the highest specific strength - the strength at which a structure breaks with respect to its density - of any known biological material, including bone, antlers, and teeth.
Researchers show that the key to obtaining diffraction data from non-crystalline but symmetric structures, such as helices, lies in matching the symmetry of the incoming radiation to the symmetry of the structure to be studied.
Scientists used NIPAM-based nanogels synthesised with different percentages of MBA (N,N'-methylenebisacrylamide) as a cross-linker in the range 10-30%, and characterised them at human physiological temperature. Detailed structural studies of these systems on a molecular length scale have not been attempted before now.
Researchers are trying to figure out the rules that govern metallic glass's creation. They are doing this by looking at metallic glasses under extreme pressures. High-pressure research can be used to probe structure on an atomic level and understand a material's state of order or disorder.
