    Ever since the industrial revolution, the world has been involved in a constant struggle. This everlasting debate between economic growth and environmental protection has come to light once again with the expansion of hydraulic fracturing, also known as fracking. While fracking was first used in the 1940s, it has not been widespread until recently when it was joined with horizontal drilling (Hoffman, n.d., para. 1). It is a process used to acquire natural gas previously inaccessible with more…

    When you hear the word permanent, what do you think about? How about if you hear the two words permanent destruction, do you hear a ringing in your ears just from those two words? Do you ask yourself, what are the consequences from permanent destruction? Well, when I think of permanent destruction of forests, I come into realization all that’s at stake. According to Alina Bradford, a Live Science contributor, states “An estimated 18 million acres (7.3 million hectares) of forest, which…

    photocatalytic reaction process [14]. Many attempts have been devoted to develop high-performance TiO2 photocatalysts for practical applications such as core–shell structure [15] nonmetal or metal doping [16–19], phase mixing [20,21], generation of oxygen vacancy [22], and coupling with other semiconductors [23–28]. In particular, coupling with another semiconductor has been widely used to improve the photoelectrochemical and photocatalytic performance of TiO2 materials. WO3 is a suitable…

    takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the…

    Global Warming Global warming is changing the environment of Earth on a global scale. The world is continuing to get warmer and because there are many ramifications which can occur and the world must n. Due to many consequences which have ensued on Earth from the ozone layer depletion, to the melting polar ice caps, and the poles switching global warming has become more of a problem. Global warming, as a result of these human activities, can have many large-scale consequences. The earth 's…

    Sodium polyacrylate is a polymer with a unique structure, that chemists are leveraging in a variety of lucrative industrial applications. Sodium polyacrylate possesses a unique chemical property: the ability to absorb incredible amounts of water. It can absorb 300 to 800 times its weight in water (Superabsorbent Polymers). Industrial chemists have taken advantage of the polymer’s special function, and have incorporated it into dozens of different products. In fact, the industry behind…

    gases from polluting the air we breath. The trees use “GreenHouse” to restore the balance in the atmosphere We should be trying to stop deforestation so it would not disappear completely. Without trees our oxygen will reduce we will have less oxygen because trees are the ones that produce our oxygen so we can breath and our air would be polluted even more with all the car and factories that we use all around the world brings many gases that have chemicals in it that pollute our air.…

    Global warming or climate change is the gradual increase of Earth’s temperature over time, through the greenhouse effect. The greenhouse effect is the rising carbon level in the atmosphere, trapping radiation, and heating the Earth. Humans are depending on fossil fuels that release these emissions. Though we have increasingly started depending on renewable resources that don’t release these harmful gases into the atmosphere, we can already see the effects today and if this doesn’t stop now the…

    Below, one representative graph and a set of sample calculations are included which will show how the values for the enthalpy of combustion of the fuel sources are deduced. Graph 1: Scatter plot showing the change in the temperature of 80.0mL of distilled water in the tin calorimeter during and after the combustion of the kerosene for the first conducted trial. The linear trendline was created for the last three data points, where the water was allowed to cool, which was then extrapolated…

    In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…
