Abstract: Devices, methods, and systems employing a multivariate optical computing sensor comprising a multivariate optical element calibrated to independently measure an electromagnetic spectral pattern of a cultivation characteristic of an algae strain in a cultivating algae water slurry and a detector for receiving output signals indicative of the cultivation characteristic. The cultivation characteristic may include, for example, total organic carbon, total carbohydrate, or fatty acid methyl esters.

Abstract: Identification of aromatic interactions, e.g. π-interactions, of mesophase formation, and methods related thereto, including the use of fluorescent light and optical imaging and/or detection schemes for the identification of π-interactions of mesophase formation, and methods related thereto. Methods include interacting fluorescent light with a pitch composition; receiving fluorescent light emissions from the pitch composition; and detecting the onset of mesophase formation upon detecting a normalized fluorescence intensity (I/I0) of the fluorescent light emissions in the range of about 0.4 to about 0.7 at a wavelength in the range of about 430 nm to about 470 nm for an exposure of about 1.5 seconds.
