More than 175 years after it was manufactured, the Oxford Electric Bell, as it is often referred to, has rung more than 10 billion times. And Nobody knows the composition of the battery yet and scientists are waiting desperately for it to die to examine its contents.
There is a lot of anxiousness and distrust in the United States about these, seemingly, rushed vaccines for the covid-19 virus. The skepticism of their safety and effectiveness runs high, understandably. I, too, was one of the initial skeptics. What changed? I did some research.
Kevlar is aramid fiber. In this article, you will learn the manufacturing process, forms, properties, types, uses, and risks to the environment and humans. You will also know the features of the wool/Kevlar fabric.
Zirconium is a lustrous gray-white metal used in the chemical and nuclear industries. On exposure to air, it forms a white protective oxide film on its surface. Its high corrosion resistance to a wide variety of acids and bases is responsible for its wide extensive application in the industries.
Research in chemistry have evolved over the years to co–opt cross disciplinary research approach. This article discusses some of they areas of chemistry that have incorporated other major disciplines and changing traditional chemistry research methodology.
The current emerging and cross disciplinary area of science and technology, and engineering called “Nano” is an interesting area that brings together many disciplines of science and technology into harmony to find a common solution. In this article, the common terms and concepts are discussed

Being stuck in a long and overwhelming rush hour gridlock isn't just an efficient however enthusiastic weight to you particularly in the event that you treat time as your sumptuous item that you would prefer not to squander. In spite of the fact that even you previously exhausted.
How a lead acid battery work and its structure.
Dry ice, or solidified carbon dioxide, and silicon dioxide were tested if they can produce voltage using sodium hydroxide as an electrolyte and aluminum metal sheet as an anode. It was tested with varying variables.
Although this is a simple lab experiment, the learning of formation of coordination complexes, calculation of the enthalpy change and the color changes on formation of the complexes gives the students a hands on experience in coordination chemistry
Educational technology helps the teachers in executing their duties and responsibilities.
Benzene and its derivatives are also called "Aromatic Compounds".The term aromatic was derived from the Greek word ‘aroma’ meaning “fragrant” and was used in Organic Chemistry for a special class of compounds. These compounds have a low hydrogen to carbon ratio in their molecular formula.
Percy Julian was able to obtain a Ph.D. in chemistry and become an award-winning African-American chemist during a time of racial segregation and Jim Crow laws.
Among the experiments to prove the existence of electrons and protons, one was Crooke's Discharge Tube Experiment.
In this K--12 project we undertake varying both the functional group of the organic substrate as well as the three most common methods prevalent for the preparation of iodoform. To the final reaction mixture, addition of sodium hypochlorite visibly increases the yield regardless of the method.
Biodiesel is an environmentally friendly option available to third world countries where agriculture is a major source of livelihood. We attempt to prepare biodiesel as part of our K12 project.
Nanotechnology deals with the study and application of materials at an extremely small scale called the nanoscale. This article is about nanotechnology and its applications in different fields.
