Medium optimization

In this research, the problems were divided into three small, medium and large groups, and for each of the solving methods the evaluation criteria was calculated. The results of this comparison indicated that non-dominated optimization algorithm outperforms the exact solving method. Therefore, it was concluded that this algorithm should be used to solve the model of real data.

A simple and sensitive modified electrode was fabricated with graphene via the drop-casting method and applied for the electrochemical detection of Sudan IV. Cyclic voltammetry (CV) was used to investigate the electrochemical behaviors of Sudan IV in phosphate buffer solution (PBS). The experimental conditions such as determining medium, scan rate, and accumulation time were optimized for the determination of Sudan IV.

The Heck coupling of haloarenes with various alkenes was successfully performed in the presence of 0.25 mol% PdCl2 and 0.5 mol% biphenyl-4-yl-[4(5)-(biphenyl-4-yl)-1H -imidazol-2-yl]ketone 2f as a ligand with Na2CO3 as optimal base, in a 1:1 mixture of H2O/DMF as the reaction solvent at 80◦C for 8 h. Imidazole 2f was found to be an inexpensive, air-stable, easily available, and efficient ligand in the palladium-catalyzed Heck reactions of aryl iodides (76%–94%), bromides (52%–79%), and chlorides (40%–70%).

In this paper, a fast, cheap, simple, sensitive and selective spectrophotometric method based on high spin peroxo-Fe(III)-EDTA complex in the alkaline medium was developed for the determination of hydrogen peroxide (H2O2) in real water samples. The purple-coloured complex with a maximum absorbance at a wavelength of 525 nm was formed. Various parameters such as type of stabilizer reagent and its concentration, reaction time, Fe(III), EDTA and NH3 concentration were optimized. The method was confirmed with the Beer’s law with a molar absorption coefficient of 267.36 L mol−1cm −1 in the 8.

Usnic acid (UA) was extracted from Usnea longissima (L.) Ach. in supercritical carbon dioxide (SC-CO2 ) medium. The selected process parameters were extraction temperature (35–45 °C), amount of co-solvent (0%–5%) and extraction time (5–9 h). These parameters were applied to Box-Behnken design (BBD) belonging to response surface methodology (RSM) to determine optimum process parameters for the highest amount of UA in the extract. g UA/100g lichen, extraction yield % and UA content values were calculated in the range of 0.045–0.317, 2.77–5.

Roses are one of the most popular fl owers in the world because of their beauty, color, aroma as well as their various uses and Red Eden rose is one of the most popular hybrid roses. Results of the study showed the most optimal medium for shoot multiplication, which was MS + 30 g/l of sucrose + 8 g/l of agar supplemented with 0.5 mg/l of BA. The optimal medium for growth and fl owering was ½MS + 30 g/l of sucrose + 8 g/l of agar supplemented with 30 μM of AgNO3 . However, NAA at all tested concentrations did not show any eff ect on in vitro plant growth.
