surface diffusion » state diffusion
protein surface » protein source, process surface
array profiling » array processing, microarray profiling
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing

• If you are trying to use Boolean operators, they must be ALL CAPS: formulations protein surface diffusion ((array string) OR (((array arcing) OR (array profiling)))).
• Adding a wildcard symbol may retrieve word variants: formulations protein surface diffusion ((array string) or (((array arcing) or (array profiling))))*.
