Could Water Be Used to Charge a Cell Phone?

Research 2014

A research team from Massachusetts Institute of Technology (MIT) recently found that water droplets can generate an electric charge when repelled from a superhydrophobic (ultra-waterproofed) metal surface. This technology may be used to develop portable devices that can harness the humidity from surrounding air, converting it into enough electricity to charge battery-powered electronics like cell phones.

Atoms, Ions and Molecules. What’s the Difference?

When you view an atom, the first question you might ask is ‘what kind of atom is it?’ What you are really asking is ‘which element am I looking at?’ You can answer this by counting the number of protons in the atom. The number of protons, neutrons and electrons is the same in a neutral atom- that is, an atom with no charge. So, in a regular Calcium atom, there are 20 protons, 20 neutrons and 20 electrons. The electrons orbit around the nucleus and have a negative charge.  An isotope is a version of the element with a different number of neutrons. Read More →

Quarks and Leptons – the Stuff of Matter

Physics is the study of matter, its composition and energy. Scientists have attempted to explain how matter comes into existence and how it operates for thousands of years. It is now known that all matter is composed quarks and leptons, elementary particles that combine in different ways to create the matter we live with everyday. Read More →
