The guluronic acid to manuronic acid ratio was estimated through colorimetric reaction with carbazole
reagent at 546 nm .
The effect of P tenuiflorus extract on alginate production was evaluated as per the standard carbazole
On the basis of the research and analysis, Louzhen Fan and team, extend the study by fabricating an experimental LED from blue to red, with the NBE-T-CQDs blended with poly(N-vinyl carbazole
) (PVK) as the active emission layer.
oligomers  have been widely studied in recent years thanks to their optoelectronic  and photovoltaic properties  and their industrial applications .

 Lewandowski M.: "Hydrotreating activity of bulk NiB alloy in model reaction of hydrogenation of carbazole
Per Guethlin, the markets for certain key feedstocks such as CLT acid, 2B acid (PR48.xx), carbazole
(PV23) and DCB (PY12, 13,14, 83,174, etc.) have "become very tight, leading to extreme price volatility."

and tetraphenylethylene moieties: convenient synthesis through one-pot "A2 + B4" suzuki polymerization, aggregation-induced enhanced emission, and application as explosive chemosensors and PLEDs," Journal of Materials Chemistry, vol.
A calibration curve was set up (y = 909.14x - 9891.9, [R.sup.2] = 0.9996), allowing for accurate [DELTA]-disaccharide quantitation in each sample, by loading known quantities (from 25 to 800 ng) of AMAC-derivatized [DELTA]-disaccharides obtained by depolymerisation of a highly purified UTI sample assayed for uronic acid (UA) content, according to the carbazole
method by Bitter and Muir .
(Supelco 442506) and cysteine hydrochloride (C7880) were purchased from Sigma-Aldrich Ltd.
Finally, the concentration of alginate in solution was determined using the carbazole
