Is the usage of "vice versa" appropriate in academic writing? I have written:


  In an oil-water system, if the particle contact angle is larger than 90°, showing greater affinity for the oil phase, then the system is likely to be a W/O emulsion and vice versa.


Does this convey "if the particle contact angle is lower than 90°, that the system is more likely to be O/W emulsion", in a more professional way, or does it seem lazy?

I hate writing repeating sentences, with a few different words.
I would make the position completely clear:


  Conversely, if the angle is …
