If we analyses industry life cycle graphs‚ the Chinese firework industry is not in growing period‚ it can be counted at maturity phase such as sunset industry. According to Chinese Firework Industry article‚ there are some challenges for future outlook in Firework market‚ such as some safety regulations and increasing environmentally conscious among consumers. Both of them force the industry to be more manufacturing and it increases the cost. In addition to these disadvantages reproducing is another

Night Runner Currently‚ there is a product on the market called the "Night Runner" ("Night Runner‚" n.d.). The Night Runner is a set of ultra-lightweight LED unit with front lights and rear tail light gives you 30 feet of hands-free illumination ("Night Runner‚" n.d.). They were initially designed for runners. However‚ they have other commercial uses as well. One of the commercial uses for the Night Runner is that it can be used by postal workers (Barbuti‚ 2016). The second commercial use is

Infrared saunas work differently from the traditional ones because the infrared technology directly heats the people while those using wood or electric stove only heat the air inside the sauna. This is why the advantages of using an infrared sauna can be even more numerous‚ including the fact that they can truly improve your aspect. Let’s see how exactly can infrared saunas make us look much better. Skin Rejuvenation Due to the fact that we constantly expose our skin to all sorts of chemicals

2.3. Characterization 2.3.1. FT-IR spectra The IR spectra of different powder were recorded using FT-IR Spectrometer‚ Spectrum RX1‚ USA. The samples were prepared in the pellet form by pressing their mixed powder with KBr by the ratio 1:10 in the Perkin Elmer hydraulic device. 2.3.2. UV-Vis absorption spectra measurement UV-Vis spectra were recorded in N‚ N-Dimethylformamide (DMF) in the range 200-800 nm. All the UV-vis measurements were accomplished by a Shimadzu PC3101 spectrophotometer‚ under

A SEMINAR REPORT ON AGEING OF BITUMEN ABSTRACT Bitumen is a common binder and has gradually replaced road tar for construction purposes mainly because of the cancer risk. It is a mixture of organic liquids that are highly viscous‚ black‚ sticky and entirely soluble in carbon disulfide. The ageing of bitumen is a complex process based on the chemical composition of the bitumen‚ the pavement structure and climate. It leads to deterioration of pavements and leads to loss of adhesive

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4
