We can work on Coachella 20 years in the making

View the entire documentary, and after you have finished, please post two reflections on a theme or a performance in the documentary that struck you the most. Each reflection should be a full paragraph (the entire response should be 1 page to 1 1/2 pages total). As you are writing, imagine how you would explain to the class
why you think those moments were so fascinating. My main request
is that you watch the full documentary, so please indicate in your
response that you have viewed it completely.

Coachella 20 years in the making

Sample Solution

iVO4/TiO2 nanocomposite was synthesized by hydrothermal method. Briefly, 0.02 mol of Bi(NO3)3.5H2O and 0.02 mol of NH4VO3 were dissolved in 20 ml of 4 M HNO3 and 2 M NaOH aqueous solutions, respectively, to form two transparent solutions. These solutions were mixed together with Bi: V molar ratio of 1:1. The orange slurry was obtained by adjusting pH to 7 with 4 M NaOH. Then an appropriate amount of TiO2 powder was subsequently added to the pre-prepared BiVO4 solution (50:50 W/Wratio) and was stirred for 2 h under ambient air. After this time, the suspension was transferred into a Teflon-lined stainless steel autoclave with a capacity of 100 ml and the hydrothermal reaction was carried out at 180°C for 24 h, and then cooled down to room temperature. The final product was filtered and washed with deionized water several times and then was dried at 80°C for several hours. Finally, the resultant sample was calcined at 500°C for 6 h. Furthermore, the pure BiVO4was prepared without the addition of TiO2 powder and was used to the next experiments. 2.3. Characterization of nanocomposite Field emission scanning electron microscope (FESEM) (FEI Quanta 200, USA) was used to investigate the BiVO4and TiO2nanoparticles and BiVO4/TiO2nanocomposite structure and surface morphology. The crystalline nature was also revealed by X-ray diffractometer (XRD, Bruker D8 Advance, Germany).FTIR spectrum of BiVO4/TiO2 was recorded using an IR spectrometer (Jasco 6300, Japan). 2.4. Photocatalytic setup All of the experiments were performed in 25 ml Pyrex beakers involving 10 ml of aquatic solutions with 500 μg/l MC-LR concentration and catalyst mixture. The pH of the samples was adjusted by 0.01 M NaOH and HCl. Then, the samples were put in an ultrasonic bath for 10 min to eliminate aggregates. Photo-catalyst suspensions were illuminated with 15 W LED lamps (white light). These lamps were located in 10 cm above beakers. Firstly, and the samples were stirred for 30 min to reach equilibrium in darkness. Then, lamps were turned on and samples were placed under magnetic stirring to maintaining agitation during the reaction to keep suspension uniformity. At the end of contact time, lamps were turned off and samples were taken and filtrated through 0.22 μm syringe filters to separate the catalyst particles before measurin>
