Study Of Blooming Bio Filler Reinforced Rubbers

In 1855, Charles Goodyear invented the first soccer ball made out of rubber. Charles was in jail for debts, but while he was in jail, he asked his wife to bring him rubber, and a rolling pin.There, in his cell, he made his first rubber experiments , kneading and working the gum hour after hour. If rubber was naturally adhesive, he reasoned, why couldn’t a dry powder be mixed in to absorb it’s stickiness? Perhaps the talc-like magnesia powder sold in drugstores? Out of jail, he tried, with promising results. After inventing vulcanized rubber, he invented the first soccer ball.

✔ Quality material - eco friendly, non toxic, high density EVA foam material, 38-40 degrees density.

Change in color once chemicals were combined (experiments b,c,d,e,f,g,h,j,l); Precipitate formation (experiments g,j,l), and formation of gas bubbles (experiment a).

The most reactive substance in this lab was the crushed liver core, it produced the most amount of heat, bubbles, and the biggest flame during the glowing splint test. The manganese dioxide and the liver core were also very reactive and they both produced a flame during the glowing splint test. Next, the potato core produced a slight reaction, but it was not as extreme as the other substances. Finally, just the hydrogen peroxide and the boiled liver core had no reaction and did not produce a flame during the glowing splint test.

The reason for the plan of this experiment is not only to find out which brand has better absorbency, but

The purpose of this study was to observe the effects of various pHs, temperatures, chemical

This remarkable characteristic is due to the chemical composition of the polymer, as the fibres are made of many polymer strands (8). These strands are comprised of two segments of a long, amorphous segment and a short, rigid segment (8). The amorphous segments allows for the elastic properties of spandex where the material can be continuously stretched and then return to their original shape and size (8). This polymer also has useful features of being light weight, easily dyed, abrasion resistant, and is unaffected by the harsh effects of perspiration, body oil, and detergents (8). These attributes of spandex makes it a popular choice of material for sports

vulgaris were prepared by repeatedly rinsing in distilled water to remove surface betalain (Flinders, 2015). A control group and two treatments were taken, the control was at room temperature (25 degrees Celsius), and the treatments were at 50 degrees Celsius and 80 degrees Celsius. Cubes of B. vulgaris were placed into cuvettes with three ml of distilled water, the treatments were started five minutes apart to ensure each treatment was recorded at the correct time. The light absorbency of each treatment was then recorded using a spectrophotometer set at 540nm, the absorbency for each treatment was checked after 0 minutes, 15 minutes and, 30 minutes in the water baths. Before measuring the light absorbency of each treatment a cuvette with 3 millimetres of distilled water was placed in a spectrophotometer to set it to zero. The absorbency in the solution was measured in arbitrary units (AU), the higher the light absorbency, the higher the plasma membrane permeability. Each treatment was gently swirled before being placed into the spectrophotometer to disperse the colour. Each treatment had three replicates to guarantee an accurate average could be recorded. The results were then collated into tables and

Through research about composite and bio-composite, there are many advantage and disadvantages in aircraft construction. Definition for composite, a material that are made from two or more constituent materials with significantly different physical or chemical properties when combined, produce a material with characteristic different from the individual components. The individual components remain separate and distinct within the finished structure. In aircraft, the first composite aircraft was in 1916, era of World War 1, when British launched a Bristol Scout from Felixstowe. Between the World War, American experiments with airship composites led to the construction of two aircraft carriers, while the British Short Mayo seaplane composite demonstrated successful transatlantic mail delivery. During the Second World War, some composites saw operational use including the Mistel, the larger unmanned component of a composite aircraft configuration developed in Germany at the end of World War 2. Experiments continued into the jet age, with large aircraft carrying fully capable parasite fighters or reconnaissance drones.

The purpose of the lab was to make observations and inferences, on how 2 types of packing material reacts to different liquids. In part one of the lab, 2 different types of packing material was placed in separate beakers of acetone and water. After a minute of stirring using the glass stirring rod, iodine, an indicator, was added to each beaker. In part 2, tin foil was rolled and placed in a solution of water and crystals. Observations were taken in all parts of the lab.

This report aimed to investigate the relationship between the air pressure in a ball and the bounce height of the ball as well as the material of a ball and the bounce height of the ball. The data collected supports the two aims and hypotheses mentioned previously in Stage 1.
