purified even further to insure quality. Because this process is so expensive it is forgone and replaced with fossil fuel polymers that are highly pollutant and will someday deplete. With Laine’s new findings we use little more than sand or rice hull‚ ethylene glycol (antifreeze)‚ and a caustic to create these silicon-based compounds that are used in the production of products such as computer chips and textiles. We can also use this process to create silicon-based polymers which could someday replace

The amount of solute decreases the boiling point. The pressure keeps the atmospheric temperature lower than the pressure with the solute. Antifreeze used in heating and cooling systems is a solution of water and ethylene glycol has a lower freezing point than pure water or pure ethylene glycol. Antifreeze is a good example of the colligative property‚ except its special because it keeps from

De-icing Background Research De-icing is defined as the removal of existing‚ snow‚ ice‚ frost‚ etc.‚ from a surface. De-icing is very important in winter in places in the north and sometimes in really cold places in the autumn. De-icing was first used to de-ice snow and ice on roads to so that all forms of transportation can continue in extreme cold weather and also has an important impact for making the roads safer for traffic

Antifreeze is made of substance called ethylene glycol. Although antifreeze is a very helpful product for humans there is a lack of its overall effects upon the environment. This is defiantly a problem‚ due to its lack of research we decided to conduct an experiment; what are the effects of different types of antifreeze on the physical appearance on a pansy plant? Ethylene glycol is actually metabolized in plants and plants have a hormone inside of them called ethylene. Inside of plant cells this substance

How the Predator UAV Works Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1Predator Unmanned Aerial Vehicle. These high-tech aircraft‚ controlled by a crew miles away from the dangers of combat‚ are capable of reconnaissance‚ combat and support roles in the hairiest of battles. In a worst-case scenario‚ if a Predator

at PET Chips division manufacture polyester chips. The process description is as follows Polyester chips are manufactured by two step chemical reactions between PTA ( Pure terephtalic acid ) and MEG (Mono ethylene glycol) The two step reaction are : Esterfication and Poly condensation Process description : PTA and MEG mixed together in paste mixing tank. Mixing of paste is done by special type of agitator. The slurry obtained in paste tank is fed to esterification reactor by screw pump

Coconut Shells as a Shoe Polish Science Investigatory Project Let us begin our adventure with our Abstract... The study focused in making a specialized shoe polish from burned dried coconut husk. It aimed to prove the affectivity of the product in terms of some parametric measurements based on the preferences made by respondents. The parameters were adapted from written reviews for top commercial products. Also‚ this was made to test if there are really no significant difference between the

CHAPTER 1 Introduction Background of the Study Like many other hygiene convenience‚ shoe polish or can also be called boot polish is usually a wax ‚ cream or paste used by people to shine‚ water proof and restore the appearance of leather shoes. This extends the footwear’s life. This is made up of many kinds of chemicals and because of this; it can cause irritations‚ allergies to us. In our generation‚ shoe polish is used every day and companies produce a lot of it to meet the demands of
