One of the oldest reputable sources that I managed to find allowing to define what "uraneous oxide" is, was Roscoe's Lessons in Elementary Chemistry [1, p. 253] (strong emphasis mine): URANIUM. Symbol U, Combining Weight 240, Specific Gravity 18·4. Uranium is a metal which occurs but sparingly in nature, existing combined in two somewhat rare ...

Two water drops 1 mm apart do not attract each other, if I omit gravity and electrostatic charges. Are they hydrophobic ? No, they are not. The relevant intermolecular forces are contact ones, decreasing very fast with high power order of distance. Water molecules in a gaseous phase have still strong attraction during their collisions, what reflects in vapor ...

I am working on the secondary structure assignment/prediction (actually I am not sure) of proteins using machine learning. Secondary structure assignment is an automated method that defines the secondary structure (helix, sheet, loop) based on a known three-dimensional structure. Secondary structure prediction refers to taking the primary structure (the ...

Structure assignment is relating e.g., a measured absorbance frequency (like a triplet in $\pu{^1H NMR}$), or a structural feature (like $\Phi$ and $\Psi$ in a Ramachandran plot) to a structure already known. It equally may be based on a putative / postulated structure; then, you compare e.g., how a simulated NMR spectrum is similar to the experimentally ...
