Green Chemistry is essentially chemistry that reduces or eliminates hazardous substances in its processes and products. It is more than cleaning up pollution or treating hazardous waste, it’s keeping the hazardous chemicals out of the environment and stopping pollution at its source. It is important because if we are to reverse climate change, we can’t just clean up pollution, we...

July 2015 my father was diagnosed with stage five kidney failure and heart failure; I remember thinking these illnesses were rare. I’ve come to find out that they aren't rare at all, the sad truth is that many people all around the world suffer from kidney disease and more severely kidney failure. There are three common treatments to combat these...

Introduction Analytical chemistry considers and employs a variety of equipment and methods in order to separate, identify and quantify matter. After the first flame tests in 1860, the importance of qualitative and quantitative analysis has been identified and major advancements have been made with many of the spectroscopic and spectrometric methods only being refined in the late 20th century. One...

Have you ever wondered how fireworks actually work? Fireworks have been used for centuries as a source of entertainment, a method of communication and for religious reasons. Fireworks were invented in China. The earliest fireworks were made from hollow bamboo stalks filled with a simple chemical composition called ‘black powder’. This powder produces a small exploding reaction when ignited. In...

Rationale Forensic chemistry is the application of chemistry, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials and instruments found at a crime scene. Forensic Chemists have a wide array of methods used to identify unknown substances including High performance liquid chromatography (HPCL), gas chromatography (GC), atomic absorption spectroscopy, Fourier transform infrared...

Organic chemistry is a chemical branch involved with carbon compounds and particularly carbon compounds found in living things. Originally restricted to compounds generated by living organisms, this branch of chemistry has been expanded to include human-made substances like polymers. Polymers are substances with a molecular structure that consists mainly or entirely of a large number of related units, such as...

I chose to study chemistry as part of a of a science degree with mathematics being my major area of study. Knowledge of basic maths is essential for understanding chemical processes and solving chemical problems. Stoichiometry is a great example of this as every step involves some level of maths, from balancing chemical equations to unit conversions. A strong parallel...

Our human health and the global environment are threatened by the adverse effects of development in different field of science. Our bodies are contaminated with a large number of synthetic industrial chemicals, many of which are known to be toxic and carcinogenic while others remain untested for their health effects. They come to us from unlabeled products, chemically contaminated food,...

Abstract Rosaniline hydrochloride (RH) is a triaminotriphenyl methane dye, which is widely used as biological stain, mordant, printing, in cotton tannings, and dyeing in textile industry. The reaction obeys first order kinetics with respect to RH and IO4-. The reaction is around hundred times faster in the presence of CTAB compared to aqueous medium under identical conditions. This is due...

Chemistry is concerned with the complex arrangements and substances of which all of matter is made from. How these molecules react with other molecules and energy has given us our understanding of the universe as it is known. Therefore, I believe it is correct to view chemistry as a “central science”. Chemistry’s importance can be seen throughout most scientific disciplines....

Systems biology is the scientific analysis and modelling which displays systemic properties as well as dynamic interactions in biological objects. This holistic approach is used in a quantitative and qualitative manner by combining different experimental studies with mathematical modelling (Klipp et al., 2016). Systems biology can be used in order to establish the relationship between bodily systems which cause changes...

Rationale It has been claimed that “future medicine will only be based on synthetic DNA (XNA) technology”. Synthetic DNA are proteins that can duplicate synthetic genetic material. It could lead doctors to begin treating diseases by allowing the synthetic genetic material to interfere and prevent vital processes in the course of the disease. In theory, this method could function on...

Abstract As it has been widely underlined in recent years, Global warming is becoming a big problem and carbon emissions from a variety of sources are the cause of it. To control emissions, several carbon emission reduction policies, and schemes such as European Sustainable Development Goals, Green Deal & Paris Agreement have been reached and put in place. However not...

BACKGROUND THE latest threat to global health was recently given the name COVID-19 caused by SARS-COV-2(severe acute respiratory syndrome coronavirus-2). FIRST case was reported in December 2019, in Wuhan, Hubei province, china and is rapidly spreading from Wuhan to the rest of the world. Many of the initial cases had a common exposure to the wholesale seafood market in china...

In terms of education, the need for students to develop beyond initial knowledgeconstructions and land at a complex, domain-specific knowledge structure is emphasized both in research and in application. Studying children’s naïve biologies adds to our understanding of how teachers should address biology and science content (Inagaki, 1990). From the literature, we can predict the trajectory of a child’s knowledge...

A cell is the basic structure of any living thing, and thus can be considered the basis of life. All life is made up one type of cell or another. A notable thing about living systems is their ability to maintain a comparatively constant state known as homeostasis. The cell happens to be the earliest level of complexity capable of...

Background Information I personally chose to investigate this topic because green beans are one of my favorite vegetables to eat, and I have tried to grow them several times with varying degrees of success. Because I was sometimes not able to grow the plants from seeds, I was interested in what variables could affect the seedlings’ growth, specifically soil amendments...

Biology, derived from the Greek words, ‘bios’ translating to ‘life’, and ‘logos’ denoting a subject of study, is defined as the study of living organisms, for example humans. The rapidly expanding human population is faced with multiple complex and severe problems, such as diseases, which could be argued to be the biggest risk to the integrity of civilisation. Diseases can...

In pre-vedic periods in India, Ayurveda was found according to Ayurvendantana, stated to be divine revelation by Lord Brahma. The valuable knowledge was imparted to Dakhsha prajapati and Lord Indra in the form of shlokas. This knowledge was learned by Bharadvaja from Lord Indra himself. Bharadvaja taught ayurveda to a group of assembled sages who passed down this knowledge to...
