The term “forensic” is derived from the Latin word “forēnsis,” which means of or before the forum. The history of this word dates back to Roman times, during which the person accused of a crime was presented before a group of...
In chemistry, a base can be defined as a substance that dissociates in an aqueous solution to form Hydroxide ions (OH− ). A weak base is a base that doesn’t completely dissociate into its constituent ions when dissolved in a solution. Some...
A chemical change is a process in which one or more substances are converted into one or more new and different substances. These substances can be either chemical elements or compounds. Chemical changes occur as the result of chemical reactions...
A decomposer is an organism that breaks down complex organic matter from dead or decaying organisms to obtain energy. It may sound unpleasant, but decomposers do nature’s dirty work. They eliminate dead or dying organisms, and while doing so...
One may think that precipitation is just about rain, but that’s not the case. In simple terms, precipitation is any type of water particles, liquid or solid, that form in the atmosphere and falls on the earth’s surface. METAR weather...
Titanium nitride belongs to a group of refractory metals in which a nonmetallic element (Nitrogen) forms a compound with a transition metal element (Titanium). This metallic compound has a brown color and appears gold when applied as a coating. It...
Styrene is a liquid hydrocarbon known for its incredible capability to undergo polymerization — a process in which individual molecules react with each other to form large, three-dimensional networks or polymer chains. Styrene is primarily...
The term ‘metal’ is derived from the Greek word ‘metallon,’ which means ‘to extract’ or mine from the ground. Our planet contains plenty of metal. In fact, out of 118 elements in the periodic table, about 95 are...
A particle accelerator is a device that propels subatomic particles to high speeds, using electromagnetic fields. It generates a beam of charged particles that is used for numerous research purposes. The history of particle accelerator dates back to...
Nitric Acid is a strong acid with a PH of about 3.01. It is a ‘sticky’ molecule that readily absorbs to surfaces, specifically if there is water on the surface. The physical state of a pure nitric acid is a colorless liquid, but older...
Carbon nanotubes are cylindrical molecules made out of rolled-up sheets of graphene. They are the stiffest and strongest materials yet synthesized. They have unique electrical and thermal properties. These nanotubes can have a variety of...
Mixtures are formed when two or more compounds or elements combine together without participating in a chemical change. Each component in a mixture retains its own chemical properties and makeup. Scientists recognize two types of mixtures:...
