    en.wikipedia.org/wiki/Non-uniform_rational_B-spline

    NURBS curves and surfaces are generalizations of both B-splines and Bézier curves and surfaces, the primary difference being the weighting of the control points, which makes NURBS curves rational. ( Non-rational , aka simple , B-splines are a special case/subset of rational B-splines, where each control point is a regular non-homogenous ...

    Boehm titration results for various chemical reactions of single-layer graphene oxide, which reveal reactivity of the carboxylic groups and the resultant stability of the SLGO sheets after treatment. Hydrazine reflux is commonly used for reducing SLGO to SLG(R), but titrations show that only around 20–30% of the carboxylic groups are lost ...
