Different Branches Of Chemistry

05.30.2010 · Posted in Education

Chemistry is generally divided into two broad branches: organic chemistry and inorganic chemistry. Other types of chemistry include physical chemistry, biochemistry, and analytical chemistry, with each field branching off into several specific subfields. Here’s a brief description of the most common branches of chemistry.

Organic Chemistry

Organic Chemistry has to do with the study of compounds that contain carbon (and sometimes hydrogen). Even though carbon is only the fourteenth most common element on the planet, it produces the greatest number of different compounds on Earth. Not surprisingly then, much of the study of chemistry involves organic chemistry.

The most studied groups of organic compounds are those that contain nitrogen. These organic compounds are important because they are often linked to the amino group. When the amino group read more...

Chemical Element Silver

05.28.2010 · Posted in Education, Research

Silver, a chemical element, exists in the periodic table with the symbol “Ag” and atomic number 47. Silver is a soft white lustrous transition metal. Due to the fact that it has the highest electrical and thermal conductivity of any metal, silver is widel used throughout the world, used in used in coins, jewelry, tableware, and photography. Silver occurs in minerals and in free form.

I’m sure if you looked you would have in your household several objects that are made of polished silver. For example: Silver dollars, or Silver cutlery, or photography equipment.

Being just a bit harder than gold, silver is very ductile and malleable. Because of silver’s physical properties as a brilliant white metallic luster it can take a high degree of polish. Copper has replaced silver in several instances due to it’s hire cost, this is especially true for electrical read more...

An Overview of Wind Farms As An Energy Source

05.26.2010 · Posted in Energy, Research, Science

With energy issues becoming a daily subject in the news, wind energy is gaining notoriety. Here is an overview of wind farms and their potential.

An Overview of Wind Farms

A wind farm is simply a collection of wind turbines in a location used to produce electricity. Wind farms can be found in the United States, but are far more prevalent in Europe. China is also beginning to invest large amounts of resources in wind farms as its energy needs grow.

The fundamentals of electricity production through wind farms are pretty simple. Highly efficient wind turbines are placed in locations where they will receive the maximum amount of wind energy. These turbines can be traditional horizontal windmills or vertical eggbeater windmills.

Regardless, the wind turns the blades as it passes, which turns a generator within the read more...
