crystals, including whether solvates and hydrates are included in the same definition: the FDA has defined co-crystals as "solids that are crystalline materials composed of two or more molecules in the same crystal lattice" with the interactions between them governed by "non-ionic interactions" [...
The MRR waveguide consists of a ring and a straight waveguide that interact in the presence of light propagation, provided that the distance or gap between them is small, usually in micro or nanometer sizes [4,5]. They are highly sought after due to several advantages such as fast ...
