The Workings Of Gas Chromatography [Infographic]
Gas Chromatography or the separation of mixtures in a laboratory setting that without any sort of decomposition can be subjected to vaporization. It is mostly used in analytical chemistry and consists of a detector, a data recording system, an injection port, a separation column and a flowing mobile phase. The qualitative analysis involves responses from […]
How to Write Better Science Papers (Tips for Writing Research Articles)
Reporting results in a scientific journal is a process common to researchers in all disciplines. However, many scientific papers fail to communicate research work effectively. Pitfalls include using complicated jargon, including unnecessary details, and writing for your highly specialized colleagues instead of a wider audience. Effective research articles are interesting and useful to a broad […]
The Chemistry Of Colored Glass
Soda Lime Glass is the most common glass type, making up an estimated 90% of all manufactured glass. Its uses include containers, windows, bottles and drinking glasses. The below percentages are a general composition only; other compounds are also present in smaller amount. Silicon Dioxide (SiO2): 70-74% Calcium Oxide (CaO): 10-14% Sodium Oxide (Na2O): 13-16% Glass […]
A Brief Introduction of Amino Acids – The Building Blocks of Proteins
Amino acids are an important group of compounds that all contain the amino group (-NH2) and carboxylic acid group (-COOH). One type of amino acid has the -NH2 group bonded to the C atom next to -COOH group. These 2-amino-carboxylic acids are the building blocks that make up proteins. The general structural formula of 2-amino-carboxylic […]
Simple Benzene Derivatives and Their Nomenclature in Organic Chemistry
Benzene is an organic chemical compound with the molecular formula C₆H₆. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom. Benzene was prepared from coal tar by August W. von Hofmann in 1845. Coal tar remained the primary source for the industrial production of benzene […]
Types of Organic Reactions – Functional Groups Interconversion
Most molecules are at peace with themselves. Bottles of water, or acetone (propanone, Me2C=O), or methyl iodide (iodomethane CH3I) can be stored for years without any change in the chemical composition of the molecules inside. Yet when we add chemical reagents, say, HCl to water, sodium cyanide (NaCN) to acetone, or sodium hydroxide to methyl iodide, chemical reactions […]
Inorganic Compounds As Pigments in Paints [Infographic]
Paints have been manufactured since prehistoric times, but until recently they were highly expensive and thus were mainly used for artwork. It is only since the nineteenth century that houses have commonly been painted. Today paints are used for colouring and protecting many surfaces, including houses, cars, road markings and underground storage vessels. Each of […]
