Mass spectrometry can help determine the molecular formula and weight of a compound as well as provide isotope abundance data. Within a magnetic field the angle of deflection of charged particles is used to discover the relative masses of molecular fragments and ions. Several peaks …
In order to treat a disease correctly and efficiently, it is important to first identify the microbe that is causing the disease. Isolating the bacteria that is causing the disease and using an antibiotic that specifically targets that microbe, can help prevent or reduce the …
Vehicles on the roads contribute to air pollution in major way. Most of the vehicle plying on road are fuelled by petrol and diesel emitting pollutants like Ozone gas, Nitrogen Oxides (NO), particulate matter, soot smog, carbon monoxide (CO), sulphur dioxide (SO2) etc These emissions …
Abstract A polymer is any number of natural or synthetic compounds which can contain thousands of atoms held together by covalent bonds. This is made up of a chain of monomers linked together. There are two different types of polymers, cross linking and linear. Linear …
Generally, atmosphere layers are hot if they contain gases that absorb some of the light that penetrates to that depth. Transparent layers are cool. The temperature of a layer is generally found by the balance between absorption of solar radiation (heating) and the emission of …
There are several grounds for the pollution of H2O – metal, organic merchandises, every bit good as municipal, industrial and agricultural. ( Burande, Causes of Water Pollution )May be the causes of H2O pollution caused by pollution beginnings of direct and indirect. Is the exchange …
Introduction The world today has adopted a varied and extensive use for polymers. Polymers have found their way into the daily activities of people. From small scale domestic to large industrial uses, polymers form a large part of human livelihood. Polymer chains are made up …
The mere mentioning of an Energy Conservation Plan may seem like a project that is too big for many. What needs recognition, immediately, is the fact that there is a dire need for energy conservation, it will save lives, and eventually may even save the …
The mechanical properties of materials are determined by performing carefully designed laboratory experiments that replicate as nearly as possible the service conditions. In real life, there are many factors involved in the nature in which loads are applied on a material. The following are some …
Polyester fibers, the synthetic fibers, are long chain polymers derived from coal, air, water, and petroleum. They are formed through chemical reaction between an acid and alcohol. In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its …
Feasible alternative fuel development is essential to sustainable resource management and the alternatives to fossil fuels as presented in Watershed offers promise and hope critical to the survival of our ecosystem. Brief History Before the Industrial Revolution, the human species relied on the sun for …
We all live on the planet that provides us everything; we do not go anywhere else for anything. We get all we need on Earth. It might sound odd but its true and we take it for granted. In certain cultures, the Earth is called …
Modern society is dependent on oil. At present, the demand of oil is supplied by fossil fuels. Unfortunately, fossil fuels are non-renewable. Soon the supply will run out, as the demand for oil will surely exhaust all resources. In addition, the use of fossil fuels …
Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances, when mixed, particles bounce off …

Introduction A microlens array is composed of a series of micro lens distributed in a regular pattern and has been usedin a wide range of photonic products. A micro lens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometers (µm). The …
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.
