Human embryonic stem (hES) cell has a unique ability of differentiating into all cell types, which leads to the development of the whole organism. As the integrity of ES cells is crucial for the developing embryo, these cells have likely evolved a mechanism that will …
It’s a rarity that we should come across a laboratory, classroom, chemistry textbook or lecture theatre that doesn’t contain a periodic table of the elements. It required the immense research and determination of the scientist Dmitri Mendeleev to show us that all elements followed a …
The environmental degradation is the deterioration of environment through depletion of resources, such as soil, water and air. When natural habitats destroyed or natural resources depleted, the environment are degraded. Here’s, one example of air pollution which lead to environment degraded in London. London in …
The time and temperature change of the reaction are graphed to identify the hanged in enthalpy and entropy that took place as the melted substance solidifies. Using the data we can then predict the change in free energy, GAG . Keyword’s: Entropy, Enthalpy, Free energy, …
The short and unpredictable nature of the conventional chemical batteries, along with the frequent replacements that they require, has created an acute need for a reliable, longer-lasting and rugged source of energy. Moreover Radars, spacecrafts, interstellar probes and other advanced communication devices require much larger …

Oil used in cooking foods is commonly derived from vegetables. Cooking oil is commonly used for frying and oil used for frying is usually thrown away. The recycling of cooking oil also provides a form of revenue for restaurants, which are sometimes compensated by cooking …
Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
