result of human activity. The intergovernmental panel on climate change (IPCC) says that human activity is the main cause of the changes seen in climate. This it does through activities that cause emissions of greenhouse gases (mainly consist of carbon dioxide, water vapour, methane and nitrous oxide). Studies of long-termed climate change have discovered a connection between the concentrations of carbon dioxide in the atmosphere and mean global temperature. Carbon dioxide is one of the more important gases responsible for the green house effect.
3. Evaluation of Biomass Energy Biomass energy is created when the biomass is collected and burned slowly to create steam. Generators then use the steam to turn it into heat and energy. It is believed that this is a very clean type of natural gas as it requires the plants to absorb the carbon dioxide from the environment before it can be used as a viable
Volcano eruptions, solar output (amount of energy the sun puts out), and the earth’s rotation around the sun all are natural causes in why the climate changes. Climate change caused by human interaction is mainly due to the burning of fossil fuels like coal, natural gas, oil, and other fossil fuels for energy. We are releasing a dangerous amount of carbon dioxide (CO2) in the atmosphere, which make the greenhouse effect stronger. There are two other types of gases that are also released by human activity, which is making the greenhouse effect stronger. These gases are methane (CH4) and nitrous oxide (N2O).
The cause of he ice caps are melting due to global warming, and the results are rising because of the sea levels and drastic change in the weather patterns. This change in our environment is caused by several events. The cause of the melting caps is due to global warming. This environmental change is caused by humans and the industrial revolution. The steady flow of greenhouse gases that traps the rays of the sun.
4. Conclusion In this work, a facile shock wave treatment for the synthesis of graphene and NG was developed which provides a simple, energy-saving and novel synthesis route. The shock synthesized graphene/multi-layer graphene and NG were evidenced by TEM, 19 Raman, XRD, and XPS measurements. The shock pressure and temperature are two important factors in the synthesis of graphene by affecting the formation rate of carbon. When the shock pressure and temperature are too low, the shock waves can not generate sufficient energy to produce carbon phase.
The table below shows how the additives affect the mechanical properties. The number of additives are numerous and show the versatility of Poly (ether sulphone) to incorporate new materials in making composites. The different additives are added as per requirement of application. For example, addition of Graphene oxide to improve the thermal and mechanical properties. The mechanical properties effect is shown through the comparison of Poly (ether sulphone) with 30% Carbon fibre and with 40% Glass fibre.
Excess of greenhouse gases in the atmosphere is harmful to the environment because it causes global warming, increases the acidity of the ocean, and depletes the ozone layer. First of all, greenhouse gases are harmful to the environment because it is the main reason why global warming is occurring. Global warming has been a major problem for years. When the Sun’s heat reaches Earth, some of the heat bounces back into
Once again, it’s a domino effect. The reefs bleach, marine life dies, and the food chain is thrown off balance. But there is a bigger issue. Reefs protect the global environment by acting as carbon sinks. Carbon sinks absorb carbon dioxide that would otherwise add to global warming.
EXPERIMENT Polyol process is used for the synthesis of the nanoparticles. A polyol is an alcohol containing multiple hydroxyl groups. This process involves hydrolysis and inorganic polymerization carried out on the salts dissolved in a polyol medium. The polyol acts as a solvent for the precursor salts because of its high relative permittivity, and allows one to carry out hydrolysis reactions under atmospheric pressure in a large temperature range up to the boiling point of the polyol. Ethylene glycol has been widely used in the polyol process for the synthesis of metal (pure and alloyed) nanoparticles due to its strong reducing power and relatively high boiling point (~1970C).
In the early 1800s, John Dalton discovered that all matter is made of atoms, and that atoms are indivisible and indestructible. Atoms are one of the most essential concepts for scientists to understand, because they explain how chemicals and elements act and react. Atoms help show what elements do when put in different circumstances and why they do that. An atom’s structure is based on its number of shells or periods. Those are the orbitals surrounding the atom where the electrons are.
