Chemistry

Every moment of every day, chemistry plays a part in all we experience. This branch of the Helium network humbly attempts to illuminate the vast array of chemical knowledge, making it accessible to all. Let our site inform, inspire, and awe you with chemical wonders.
Niels Bohr's contribution to chemistry
By: Ramona Taylor
Niels Bohr was the brilliant Nobel Prize winning physicist who helped the world understand quantum mechanics. His genius helped unlock the secrets of the atom; however, Bohr’s contribution influenced more than physics. His work was also crucial to physics’ sister science of chemistry. From...

There are several simple methods to determine if a substance is an acid or a base. They are litmus paper, pH paper, phenolphthalein solution, portable hand held pH meter, or pH wax pencil. Litmus is a mixture of blue dyes that has been used to...
Lab equipment for blind chemists
By: Helena Whyte
There hasn't been much new in assistive devices for the blind in laboratory equipment in the last thirty years. Chemists can still use an opticon, an optical character reader, to read science books and periodicals. Even though voice activated software is used to read digitized...
Why carbon is the basis for so many compounds
By: Elaine Sihera
Life on earth depends on the existence of large molecules built around chains of carbon atoms. Chains and rings are fundamental to the way life forms build themselves which puts carbon in a class of its own. With carbon having the largest range of subtle...

Chemical engineering is that branch of engineering about transformations. Through the applied principles of science - chemical engineers pioneer concepts on new materials, design processes, and produce new technologies. The magic of this branch of applied science is about gaining fundamental knowledge about a substance...

In the late 1800s, isotopes puzzled scientists and transformed how science viewed the nature of atoms. However, the confirmation of and understanding of isotopes has lead to some incredible possibilities that go beyond scientific experiments. Now, these odd atoms serve as tools in modern diagnostic...

As the name suggests, molecular mass is the mass of a molecule. You will hear terms such as molecular weight, formula weight, formula mass, and molar mass used in conjunction with molecular mass. There are very slight differences, but the general concept is the same...
What are aerogels and how are they used?
By: Elaine Sihera
Aerogels are unique materials. Regarded as the most useful substance ever created, aerogels are the lightest solids produced. They consist of a fine network of bubbles, containing over 95% air, or whatever gas the designer wishes to include, with cell walls just a few atoms...
How to get kids interested in chemistry
By: Madhusoodanan K.P
One of the best ways to get kids interested in chemistry is through some practical demonstrations, such as making colored soap bubbles,green flames etc. Show them,that every day objects which we all use, from bread to blankets,from shoes to school bags are...
Understanding the periodic table of elements
By: Elaine Sihera
Everyone would have learnt about the periodic table of elements at some point in their lives, most likely at school in science lessons. If one is not keen on science, it would have been a passing experience to fulfil the mandatory association with it. However...
