Although the precise ligand sphere of component II remains contentious [15] [17], we have used 15N- and 13C-labelling to identify the coordination of the carbonyl of Ala2, while site specific 15N-labelling and multifrequency CW-EPR simulations supported simultaneous coordination of His6, His13 and His14 in a {COA2, NImH6, NImH13, NImH14} coordination sphere [15].
As we have the total of individual volumes (V v ), with a single division we can get the precise number of spheres in the unit volume containing those spheres.
Crucially, each laser shines at a couple of distinctive wavelengths depending on the precise size of the sphere, as shown in the graph.
Easy synthesis and synthetic versatility: AuNPs could be made in precise control over shape (sphere, rod, nanoshell, nanostar, triangular, nanocage) and size (1 150 nm) [15, 19 21].

The joint mission between Nasa and Stanford University uses four of the most perfect spheres - ultra precise gyroscopes - to detect minute distortions in the fabric of the universe.
Who could have predicted that this amazing, smart, decent, deeply funny and very handsome man would plop into my complicated sphere at that precise moment in time, becoming the surprise love of my life and the anchor of my family?
Teams in Germany and Japan produced similarly precise measurements using the silicon-sphere technique.
As an instructor at the University of Chicago from 1956 to 1958, Smale achieved notoriety by proving that there exists an eversion of the sphere (meaning, in a precise theoretical sense, that it is possible to turn a sphere inside out).
Why can we not conceive of a social science which could and would function as the theoretical natural sciences function, and yield precise unconditional predictions in the appropriate sphere of application?
For precise, spherically symmetric targets, such as homogenous spheres and multilayered concentric spheres, the Mie theory [26], the very first exact solution of Maxwell equations, can be applied.
