Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

The statehouse is built in the Greek Revival style which is a design type based on the buildings of Ancient Greece. This was popular in the US from 1820 through the early 1860s. It’s a masonry building consisting of Columbus limestone on the exterior which was taken from a quarry on the banks of the Scioto River. I chose to describe the architectural elements of the back side of the statehouse. Looking at the portico at the center of the building, the top contains the pediment space. The sima…

Classical, utilising Greek and Roman traditions to create an inviting exterior for the city’s library. The library’s Grecian influence is obvious at first glance, as four massive Ionic columns tower above the short flight of steps before the library’s door. These steps run perpendicular to the shallow porch behind the columns. While the portico offers some standing space, the axiality of the front steps encourages…

multifarious Greek architecture influenced buildings today. For example, countless buildings in our country’s capital , Washington D.C , have Greek columns (Doc.1). Similarly, the Lincoln Memorial has Doric columns. The Supreme Court has Corinthian columns. Even the Jefferson Memorial has Ionic Greek columns. Not only Washington D.C has Greek columns , Greek columns…

of the stimuli, including the control group without a stimulus, will be written in the left hand column under the title “stimulus”. Next to the stimulus column, there will be three columns titled “number of mealworms in stimulus chamber after 1 minute”, “number of mealworms in stimulus chamber after 2 minutes”, and “number of mealworms in stimulus chamber after 3 minutes”. Under each of the three columns relating to the minutes passed, the corresponding data will be collected for each stimulus.…

Paper Chromatography Paper Chromatography is an analytical method that is used to separate coloured chemicals substances, especially pigments. This is how paper chromatography is conducted: Materials Chromatography Paper (Can also be Coffee Filter) Large Beaker (max one litre) Paper Clips/Sellotape & Skewer Stick Water soluble black marker Water Procedure: Draw a ink dot with the marker on each one of the chromatography paper near the bottom end of the paper. Then stick or paper clip the…

in total, these arches were used as entrances for spectators as well as exits to remove the bodies that were slain in the arena. The arches were supported by columns, each story contained columns of a different order. The bottom story consisted of columns from the Doric order, the most simple of the three; it consisted of a simple column with the top flaring out to a flat capital. The second level used…

documented in “Elements” by Euclid. However, the use of golden ratio can almost be found everywhere in the Parthenon. The height of the columns perfectly satisfy the golden ratio with the structural beam on top of the columns. The wide of the columns also stands in golden ratio with the distance between the center line of the columns to the outside of the columns. It’s not even that necessary to mention that the golden ratio appears in the height of the roof support beam and in the highly…

Meaning where each dilution is going to take place and where to adding each substance into. In this case: Row A: was skipped completely, Row B: Columns 1-6 were for the untreated control cells (cells only in normal media), Row B: Columns 10-12 were for treated cells with plumbagin, Rows C and D: were for cells treated with doubling dilution of our reagent/chemical, and lastly Rows E and F: were for cells treated with doubling dilutions of…

results are listed and taken into consideration to get an accurate comparison. 2. The type of column used is listed, this column contains the stationary phase and the mobile phase is pumped through the column under pressure. The dimensions of the column are listed as this will determine how much stationary phase is inside the column. As well as the size of the stationary phase particles, the amount in the column can determine how quickly the sample will pass through i.e. if there are a small…
