Fabrication of self-assembled film used 792(silane coupling agent), citric acid, boric acid and triethanolamine as the main materials. Through orthogonal experiment and the single factor analysis experiment, the optimum technological conditions are 792 10mL·L-1, citric acid 24g·L-1, boric acid 8g·L-1, triethanolamine 7.5mL·L-1, temperature 20~21°C, time 10min. Simulated sea water (3% Sodium chloride) is applied to measure the effects of the film. The results show that the processing is simple, tank liquor is stable, and film is uniform, dense and colorless.

Abstract A manual and automated method has been developed in which a new "aqueous" o-toluidine reagent is used that is compatible with standard tubing throughout the system. Citric acid, boric acid, and thiourea are incorporated, to increase absorbance readings. The sampling rate is 50/h, and the sample volume is 0.12 ml. Measurements may be made at either 630 or 385 nm.

This study aimed to evaluate the effects of three acids; Citric, Oxalic and Boric acids 0.05% on the viability of Beauveria bassiana and Metarhizium anisopliae spores after 1,2, 3 days of exposure 27±1 C° and the growth on chitin agar was obtained after 5 days at 26 ± 1C°.The results showed that the rate of viability of B. bassiana and M. anisopliae with boric acid was 312.3,209,150.3 colony/ml and 318,294.7,157.5 colony/ml respectively during three period time of in comparison with control and spore suspensions with the other acids. Spores of both fungi B. bassiana and M. anisopliae showed maximum rate of viability in the suspension supplied with citric acid which were 266 and 293.6 colony/ml, respectively after 1day of exposures to this acid in comparison with viability of control and other periods. Spores viability was lost with oxalic acid. On the other hand, control recorded highest rate of radial growth in the control was 1.92, 4.4 cm on the medium chitin agar after 3 days of incubation in comparison with other treatments. Both fungi showed best rate of radial growth 3.12, 1.88cm after 1and 3 days of exposure to citric acid, respectively in comparison with other treatments. There were no such growths on chitin agar after exposure the oxalic acid.
