Nicknamed ‘graphene’s cousin’, silicene - a form of silicon made from a two-dimensional lattice structure of silicon atoms - has been touted as a super-material in its own right, and now, computer engineers in the US have managed to make a transistor out of this notoriously tricky material.
This feat, achieved by computer engineer Deji Akinwande from the University of Texas and his team, has proven for the first time that silicene can be stabilised and sandwiched into a functioning transistor device - something no one thought would even be possible. Scientists have theorised about the existence of silicene for over two decades, but it wasn’t until 2010 that anyone was actually able to make it. “For logic applications, graphene is hopeless,” Guy Le Lay, a materials scientist at Aix-Marseille University in France, told Peplow. “If we can get good properties out of it, it can be translated immediately by the semiconductor industry,” Akinwande told her.
We’re excited to see what comes next. Precipitation Reactions: Crash Course Chemistry #9. Acid-Base Reactions in Solution: Crash Course Chemistry #8. Decomposition reaction - Chemistry.

These are the first few posters I’ve come up with – each has a large icon representative of the reaction type, as well as a short description of the reaction, and an example. Hoping to add a few more over the next few days! Click the image to enlarge and make it readable, or, alternatively, I’ve copied the text from the posters into the post below.
You can download printable versions at the foot of the page. Addition/Synthesis Reactions: Chemical Reactions Posters – Part II. Click to enlarge Here’s the second part of the Chemical Reactions posters, this time featuring condensation, hydrolysis, displacement, oxidation, and reduction reactions.
Click the image above to enlarge and read the text, or, as previously, I’ve included the text separately in the post below. Print-friendly versions are again available to download at the foot of the page. Condensation Reactions: A condensation reaction is one in which two molecules combine to form a larger molecule, with the loss of a small molecule. Example: CH3NH2 + CH3COOH → CH3NHCOCH3 + H2O.

In a chemical reaction a reactant is consumed during a reaction while a product is formed as a result.
In this game two examples of chemical reactions are highlighted: combustion and gasification. In both cases a hydrocarbon (such as oil, coal or wood) and oxygen are the reactants, while the products vary depending on the process and amount of oxygen. Any product of a chemical reaction that is not the intended product of the reaction is a by-product. In combustion processes, heat is the main intended product, and the chemical compounds that are produced are considered by-products. The by-products produced by combustion depend on the type of reaction and reactants present. There are two types of combustion: complete and incomplete. Gasification converts hydrocarbons by reacting them at high temperatures with a controlled amount of oxygen and steam.
The Six Types of Chemical Reaction. All chemical reactions can be placed into one of six categories.
Here they are, in no particular order: 1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. Decomposition Metal Hydrogen Carbonate chemistry Animation. The Science of Fire - Interactive. Reaction Types.
