Carbon-14

Recently, water and food pollution are the important global concern in environmental protection and human health due to their numerous harmful activities. There are many pollutants producing by human day-by-day including nitrate, fluoride, pesticides, mercury, lead, arsenic, and nitrite resulting from oil spills, burning of the fossil fuels, dumping waste and sewage of factories, and etc. Among them, nitrite was widely used in the food industry, pharmaceutical and agriculture as an additive in foods

Introduction Due to outstanding mechanical, thermal and electronic properties, graphene is receiving increased attention by the scientific community. Exceptional properties of graphene are owing to its hexagonal monolayer of honeycomb lattice packed with carbon atoms. The mechanical properties of graphene have been extensively

Molecular Dynamics Based Investigation to Study the Effect of Pair of Stone-Thrower-Wales Defects on the Mechanical Response and Failure Morphology of Graphene G. Rajasekaran, Rajesh Kumar and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT Structural defects are inevitable in graphene due to its production techniques as well as chemical and heat treatment processes. These defects in graphene are introduced

have lost limbs find it hard to pay for them, since they’re very expensive, so I looked into materials used, which are currently plastics such as polypropylene and carbon fibers. However, there are still some problems such as slow reaction time so manufacturers and laboratories are looking into alternate solutions such as carbon nanotubes and microchips. Research is expensive though, so I do not see the cost of

the Buckminster Fullerene is the third allotropic form of Carbon, with the other two being Graphite and Diamond. The more proper term used to describe these compounds in regards to Carbon compounds would be Graphenes. (22) The Buckminster Fullerene was first discovered in 1985 by scientists Harold Kroto, Rickard Smalley and Robert Curl. (1) They were able to discover that when Graphite is vaporized by a laser, a variety of large Carbon cluster compounds were formed, the C60 compound or Buckminster

Recently alternative fuels have been gaining popularity, especially here in the United States. The advantages of many of these fuels are being recognized with the rising cost of crude oil. Other countries around the world have been using alternative fuels for years, such as in Brazil where they have good feedstock for some fuels such as ethanol. Biofuels are also becoming cost effective with higher crude oil prices and can be completely renewable. The best thing about many of these alternative fuels

Molecular Simulations on the Mechanical Response and Failure Behavior of a Defective Graphene: Cases of Stone-Thrower-Wales (5-7-7-5) defects G. Rajasekaran Rajesh Kumar and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT Structural defects which are inevitable during the production, chemical and heat treatment processes can affect the mechanical properties of graphene and also defects can be deliberately

Making Cars Lighter Cars have been around for many years. The first car to move off its own power was in 1769, and 1989 the average weight of a car was about 3,000 pounds. Overtime, cars have been through many changes and improvements. Car makers are constantly in search of improving cars to be better than the last. Can lighter cars be safer? Can the fuel economy benefit if the production of lighter cars were to increase? And lastly, what are alternative composites car makers can invest in? Making

India ABSTRACT Keywords: graphene, defect engineering, Stone-Thrower-Wales defect, crack bridging, stress intensity factor, fracture toughness. 1. Introduction Graphene is a hexagonal two-dimensional (2D) monolayer of honeycomb lattice packed carbon structure that was discovered and successfully isolated from bulk graphite just a few years ago [1]. It is a promising candidate in a number of mechanical, thermal and electrical applications [2-6], owing to its outstanding physical properties [2]

Al., 2015) and are better known as starches and sugars. Their molecular compound is made of Carbon, Hydrogen, and Oxygen; very often in a Cn(H20)n ratio. (Reese, Et. Al., 2015) Monosaccharides (e.g. glucose, fructose, galactose) are the monomers of carbohydrates. (Reese, Et. Al., 2015) Two or more monosaccharides are disaccharides (e.g. sucrose)
