Abstract Contaminations by heavy metals in aquatic ecosystems strongly affect foodchain relationships through the process of biomagnification. Heavy metals (i.e. Fe, Cu, Mn, Pb, Zn, Cd, Cr, and Co) were determined from sediment, water and macrophytic species (Ceratophyllum demersum, Phragmites australis, and Potamogeton crispus) of Nigeen lake. The concentration of different heavy metals was determined using atomic absorption spectrophotometer. The...

Abstract Silver/Chitosan nanodispersion (Ag/CS) prepared by gamma ray was used to modify the thin-film composite reverse osmosis (RO) membrane. The silver nitrate solutions were added to the chitosan solution with different concentrations of 5 to 20 (wt/wt %) and exposed to gamma radiation at different irradiation doses. The size of the silver/chitosan nanodispersion is investigated by transmission electron microscopy (TEM)....

Rationale The big issue is that I want to see if chemical reactions will happen faster if they happen at different temperatures. So, I will see if iodine solution and starch solution will react faster if they are at room temperature, at 40 degrees and if they are cold. So, I will be recreating the Iodine Test Background Research: The...

Abstract Heavy metals beyond the threshold concentration in nature are often considered as phytotoxic. They cause damage to environment by affecting the soil fertility, biomass, crop yield and the human health. There are various approaches put forth by researches, but the most cost-efficient emerging remedy is been seen as phytoremediation; where the plants are itself involved partially or substantially in...

“All substances are poisons; it is the dose that makes the poison.”, Philippus Aureolus Theophrastus Bombastus von Hohenheim stated. Heavy metals are commonly characterized as metals with a high toxicity level in high concentrations generally with high atomic numbers, atomic masses, or densities, and those metals are located on the 3rd-15th groups and through the 4th-6th periods. Moreover, heavy metals...

Inquiry-based learning (IBL) is a student-centered Pedagogic strategy, a process that is ideally led by students. This strategy aims to teach students science by doing it, to attain conceptual change, or accommodate new knowledge, as Jean Piaget's theory of cognitive development claims. To achieve that, students work collaboratively. Build on previous knowledge and one another’s work engaging in active self-directed...

Introduction Steel often interacts with hydrogen in a variety of ways, especially because steel is used typically in structural components. Today these applications may vary from bridges to the transportation of natural gas, making the knowledge of this interaction useful [1]. Due to its high chemical reactivity, hydrogen can diffuse into the surface of steel and then appear ionically or...

Introduction While coacervates are not alive, they are good representations of how early life may have formed from simple organic substances under the right conditions, which eventually led to the formation of prokaryotes. Under suitable conditions, life-like structures can form naturally from relatively simple materials. In the 1920’s, a scientist named Oparin predicted that biological molecules would form in an...
