product density of hydrotreated GO obtained using CAT-E and CAT-C. The density of hydrotreated GO from CAT-C at 370◦C was 0.8148g/ml whereas at the same temperature the density of hydrotreated GO obtained from CAT-E was 0.8302 g/ml despite sulphur and nitrogen in the GO has been reduced to less than 50 ppm and 1 ppm respectively. The reason for higher density would be due to higher aromatic content in the hydrotreated product obtained from CAT-E. This indicates that the nature of support of the…

compared to normal rain. Lightning and erupting volcanoes release some chemicals that cause acid rain, but human activities are the major cause with reference to the graph in Appendices 3 (National Geographic, Acid Rain). When humans burn fossil fuels, nitrogen oxides and sulfur dioxide are released and dissolve in water to produce sulfuric and nitric acid in rainwater with reference to Appendices 2. The ecological effects of acid rain are seen in streams, lakes, and rivers most clearly. As it…

Dangerous Airbags “Upon rapid deceleration of the vehicle, an airbag can be propelled against the passenger at speeds approaching 200 miles per hour.”(www.newlinlaw.com) When you get into an accident and the airbags go off, they mostly save lives, but sometimes they can cause injuries to the passengers in the car. Manufacturers can make the airbags dangerous for the occupants in the car. Accidents can cause rapid airbag inflation. Because of the rapid inflation of the airbag, it can cause many…

They contain nitrogen, carbon, hydrogen, and oxygen. Proteins are recognized as compounds that make up living organisms and are essential to their functioning. Whether found in humans, animals, plants or in single-celled bacteria, proteins are made of units of amino acids…

• West: Assessment of CCI of various stopper, vial, and stopper blowback feature combinations. Samples with air headspace stored in nitrogen environment for four weeks: 5 of 240 samples showed evidence of a leak (drop in oxygen concentration between 1.3% and 3.4% atm). Results used by West for marketing poster. CCIT, Dry Ice • BioMarin: 130 glass vials with liquid (diluent) stored for two weeks on dry ice. Correction of total pressure measurement for carbon dioxide ingress into positive…

Direct methane activation into chemicals and fuels can be compared to converting lead into gold, as methane is an inert molecule with few methods of selective transformation. Methane is a ubiquitous byproduct with the potential to create more efficient chemical syntheses and replace the current petrochemical feedstocks through less expensive and more readily-available alkanes . C-H bond activation frequently occurs at transition-metal centers , often with high selectivity and trivial conditions.…

emission of light waves from the sun includes the visible light spectrum, so the colors are visible to the human eye. When the waves of light pass through the different layers of the Earth’s atmosphere, the beam of light can strike either an oxygen or nitrogen molecule in the air, and cause scattering the happen. Scattering…

Over the past year in 2016, the highest average temperature recorded on Earth was experienced 1. Many researchers believe this to be partially because of greenhouse gasses, including carbon dioxide 2. However, carbon dioxide is essential for the photosynthesis of plants, allowing plants to be successful autotrophs by using carbon dioxide, water, and energy from the sun to produce glucose and oxygen. One of the main sources of photosynthesis in a plant is in the leaves. When leaves decompose they…

Use of Carbon Compounds as Fuel: Carbon based fuels: What makes a good fuel? What are these fuels used for? Combustion effects good bad The main carbon based gases in use today are coal, gasoline and natural gas. Coal: The chemical formula of coal is C135H96O9NS. Nearly 85% of Coal is made up of Carbon and the rest is mainly hydrogen and oxygen. Coal doesn’t have a melting point. Like all fossil and biofuels, all different kinds of coal produce CO2 when burned. Coal energy quality varies…

of thymol had no significant effect on digestibility of dry matter (DM), organic matter (OM), crude protein (CP) and acid detergent fiber (ADF). The main effect of thymol on neutral detergent fiber (NDF) and ether extract (EE) digestibility and on nitrogen balance (NB) was significant (P 0.80) between the two experiments. Carvacrol was kindly supplied by Khorraman Pharmaceutical Company (Lorestan Province, Iran). Feeding and sample preparation for analysis Diets were fed twice daily…
