Introduction to the dye-sensitized solar cell (DSSC)
By: Alexius Tan
Introduction to the dye-sensitized solar cell. As the name suggests, it is a type of solar cell that is “sensitized” by a dye. What does this actually mean? Before further confusion occurs with the emergence of more scientific terms, some simple theory of electricity...
The formation and expansion of the periodic table
By: Nick Somoski
Chemistry students and scientists alike use the periodic table of elements as a source for answers and new discoveries. It serves as much more than an educational cheat sheet; it's composed of numerous bits and pieces of information about each chemical element and its properties...
What is a gravitational keyhole?
By: Jose Juan Gutierrez
A gravitational keyhole, also known as resonance keyhole, is a small section in a planet’s gravitational region where gravity would alter the orbit of a passing asteroid, causing that asteroid to change its path on a future orbital approach. The keyhole refers to the...
The formation and expansion of the periodic table
By: Cicely Richard
The periodic table is an organized table displaying chemical elements by their increasing atomic number. The table subdivides elements by their unique properties. The modern periodic table has expanded from the time the table’s creator Dmitri Mendeleev developed it to include the first known...

Quite simply, astrometry is a field within astronomy that deals with the positions and movements of celestial bodies. Emphasis is placed on accurately determining the movement of stars and other objects. Astrometry uses this information to provide information about how the bodies in our...
Contacting Aliens
By: Robert Hoglund
As of now, we have no evidence that alien civilizations exist. However, we occupy and observe a very small part of a huge, perhaps infinitely large universe. I will tackle the question at hand supposing that we have found evidence of an alien civilization already...
What is cold welding?
By: Jose Juan Gutierrez
Cold welding involves joining two pieces of metal together using intense pressure and without the application of heat. Cold welding is a solid state process in which pressure at ambient temperature initiates coalescence between two metals. The pressure produces deformation until a desired state is...
What is cold welding?
By: Olivia Kay
Cold welding is the process of bonding two objects together without heat and without any melting taking place. It is totally opposite of traditional welding as the two objects do not change state as they combine into one. Objects that are cold welded combine through...

As a result of serious meltdowns in the Ukraine and Japan, safer alternatives to uranium-based nuclear energy are being sought. The chemical element thorium has come into the spotlight as a possible alternative. What is thorium? Thorium is a naturally radioactive chemical element with an...
What is the Kuiper Belt?
By: Jose Juan Gutierrez
The Kuiper belt is a region of the solar system that lies further beyond the orbit of Neptune. The Kuiper belt is populated by objects, including asteroids, comets and other ice dwarfs. The name with which these objects are collectively known is Kuiper belt objects...
