“…Typically, the L-CNT-TiO(2) film exhibited an ultrasensitive fire-response signal of ~0.30 s and a long-term warning time of ~1238 s when a fire disaster was about to occur, demonstrating a reliable fire-alarm performance and promising flame-resistance ability. More importantly, the L-CNT-TiO(2) biofilm also possessed a water contact angle (WCA) of 166 ± 1° and an ultraviolet protection factor (UPF) as high as 2000, resulting in excellent superhydrophobicity, antifouling, self-cleaning as well as incredible anti-ultraviolet (UV) capabilities. …”

“…This technique involves using tetramethylammonium hydroxide (TMAH) as a catalyst, followed by analysis using gas chromatography equipped with a flame ionization detector. Recoveries of EE-EPA and EE-DHA spiked between 5 mg/g and 20 mg/g were found to be between 90.8% and 95.2%, with coefficients of variation ranging from 0.2% to 2.5%, demonstrating the accuracy and precision of the technique. …”

“…All samples were transformed into methyl ester and analysis of fatty acid methyl esters were performed by gas chromatography (GC) with 60 meters capillary columns and flame ionization detectors. RESULTS: TFAs ranged from 0.6% to 3.5%,with linolelaidic acid (C18:2 9t, 12t) being the most common form of fatty acid in Iranian mayonnaises, which had high amounts of SFAs (from18.1% to 24.9%) and unsaturated fatty acids (68.4%to 74.4%). …”
