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.
Chemistry science fair projects: Which cloths offer the most protection from fire?
By: Ernest Capraro
Your lab partner spilled the bottle of alcohol all over the floor again, only this time a nearby Bunsen burner set it ablaze and you’re standing right in the middle of it all. Good thing you weren’t wearing your favorite outfit today. Just...
Exploring advanced chemistry degrees
By: Ernest Capraro
If you’re considering a graduate degree in chemistry, congratulations, you’re about to explore a fascinating realm. You’ll have a bit of decision-making before you can really get started. There are literally hundreds of options to consider, as you look at the degree...

The dictionary defines fireworks, also termed pyrotechnics, as manufactured chemicals designed to make a loud and brilliant explosion when lit. That hardly does justice to the awe they inspire in young and old alike. We never outgrow the fascination of watching the stars burst, the...
Matter Plasma Photons Bose Einstien Condensate Liquid Crystal
By: John Traveler
Typically we think of matter in terms of three states, solid, liquid and gas. There are actually several other states of matter which have been discovered to exist. Photons are a type of matter, or perhaps more aptly stated quasi-matter which exhibit no detectable or...
Planet made mostly of hydrogen and helium
By: D. Vogt
Much like the Sun itself (and the giant molecular cloud from which it formed), the outer gas giants - Jupiter, Saturn, Uranus, and Neptune - contain large proportions of hydrogen and helium gas. The two closest of these, Jupiter and Saturn, in fact are made...

Black chemists have been contributing to advancements and developments in chemistry since the first chemists existed. We cannot forget that the first man and woman were chemists who worked with plants and substances to understand and to use their properties. Since the origins of man...
Exploring the ozone layer
By: Sharon Mazaka
The glowing sun's energy heats the earth and makes life on earth possible. Plants, animals and humans need the sun to shine brightly so they can live a healthy life, but the strong ultraviolet light from the sun can be extremely dangerous. Fortunately way...
What is a polymer?
By: Samuel Lamphier
Poly(3,4-Ethylenedioxythiophene), a transparent conducting polymer with the acronym PEDOT that exhibits characteristics of Green Chemistry. PEDOT displays many qualities that make it considerable for use in applications as an environmentally friendly polymer. PEDOT has favorable properties of a low band gap, high conductivity, periodic...
Atomistic modeling: Using computers to model nanoscale particles
By: Samuel Lamphier
In a world where technology has evolved so rapidly a great focus has been placed on nanoscale materials. These materials possess greater properties than their bulk material. Properties such as superior strength, resistance to cracking, high temperature applications and almost everything you can think of...
Why helium makes your voice squeaky
By: Lynette Alice
While it is fun to use helium to make your voice high and squeaky, it is actually equally fun to know why it does that. Something important to keep in mind about helium and voices is that helium does not change your voice, it changes...
