Recent research shows that AgNPs enhance luminol fluorescence and chemiluminescence by acting as a catalyst with hydrogen peroxide. When AgNPs interact with hydrogen peroxide they cause the peroxide to degrade into superoxide and hydroxyl radical, which also react with luminol to form 3-aminophthalate (Equations 2-5) [13]. The further degradation of hydrogen peroxide into other reactive oxygen species promotes higher fluorescence intensity. Figure 5 shows the increased fluorescence intensity…

A few weeks later, I had written my book. I had some more mysteries that confused me. 1. Why are people’s marriages so weird? 3. Why was it so difficult to train Sandy? 5. Why did everyone get mad when I decided to practice Physics in the kitchen? I believe that the reason why mother didn’t love my father was because of his aggressive personality. When I didn’t listen to him, he easily lost his temper, but things have changed now. First, father asked mother if she could go out for dinner with…

We have one planet to live on. Have you ever thought of that? We only have this one giant rock, hurtling through the sky at speeds too fast for us to even comprehend; and we have nowhere else to go. Yet, we still take advantage of our home. We pollute it, mine mountains, clear-cut forests and think nothing of it. In everyday life people normally like to keep their home clean and tidy, they may buy insurance to help them buy a new one if something happens to their old one. Earth is our home, yet…

Pyrite, also known as fool's gold, is similar in color and shape to gold, and is easily mistaken for gold because it generally occurs naturally with gold. Pyrite, though, can be easily distinguished from gold by running some simple tests and doing some simple observations. Pyrite can form in many areas and shapes, the larger crystals can be perfectly formed into intriguing cubes, penetrating twins, and many other fascinating forms, while the smaller crystals can give of a shimmering or…

where mCO2 is the mass fraction of CO2 in the solution, and MWsolution, MWbrine, and MWCO2 are the molecular weight of the solution, of the brine, and of CO2, respectively. Considering the definition of density as shown on 5.5, equation 5.3 can be modified to equation 5.6. ρ_CO2=MW_CO2/V_CO2 (5.5) "1" /"ρ" _" solution" =("1-" "m" _"CO2" )/"ρ" _" brine" "+" "m" _"CO2" /〖"ρ" _"CO2" 〗_" " (5.6) where ρ solution and ρ brine are density of solution and brine, MW CO2 and ρm CO2 is…

Nanocrystals (NCs) are interesting material, as their electrical and optical properties can be tuned by tuning their size or surface area. They have diverse applications in electrical devices. Nanocrystal thin film transistors (NC TFTs) have been intensively researched, because of their low-temperature processability.1,2 Colloidal NCs are synthesized in a liquid solution containing some stabilizing organic molecules, broadly termed as surfactants, which are bulky and insulating ligands. The…

The removal of carbon dioxide in Recirculating Aquaculture Systems (RAS) has been an important topic of research due to the increasing amount of recirculating aquaculture systems being employed in the aquaculture industry. Carbon dioxide, as well as ammonia, are excreted by the fish and can be present in high quantities. Elevated levels of CO2 accumulation within the recirculating water could have toxic effects on fish. The maximum level of CO2 and ammonia that can be present in the tanks…

In Webster’s dictionary the definition of Environmental Science states that, it is “the branch of science concerned with the physical, chemical, and biological conditions of the environment and their effect of organisms”. In the experiment Environmental Science deals with how the human body will be affected in the environment with or without using electrolytes during an exercise. While conducting the experiment Aleckzar used his brother Alekczar to see if there would be a significant difference…

Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

Magnesium is a mineral that can be described in so many different ways. It is almost impossible to name every little thing that magnesium may assist in to help our body function. To start with, magnesium is roughly involved in 300 essential reactions that happen within our body. The adult contains about 25g of magnesium in their body. Magnesium has specific recommended consumption level. If there is not enough magnesium in the body, it can cause multiple problems or illnesses. The same applies…
