Ideas Put to Work!
Here is the thermodynamic proof that Cp/Cv=Kt/Ks. It is pretty straight forward if you use the cyclic chain rule.
I hope this helps some of you. I know this is a common question that is often asked in Physical Chemistry (P-Chem). If this is helpful and you would like to see the proof for another thermodynamic identity, leave me a comment and let me know!
Most us have heard about Silicon and how important Silicon is for generating our indispensable computer electronics. Some of us have even heard about Graphene, the one-atom thick carbon sheets that can possibly solve the issues related to reducing the size of current and future computer chips even further. However, have you heard about Molybdenite yet? Check out this article that explains how Molybdenite might be competing with Silicon and Graphene to be the next generation material for making future computer chips.
If you are looking for a great off-road car, jeep is always a safe bet. However, you might be wondering if you get the same off road performance out of a new Jeep Grand Cherokee compared to a new Rubicon. Well, I can tell you that both of these vehicles can take you far. However, if you are a serious off-roader, the Rubicon gives you the additional advantage to not only lock your front and rear axle differentials but also to disconnect your sway bar. What does sway bar disconnect mean? Check these following pictures which show how the sway bar disconnect of the Rubicon performs in comparison to the Grand Cherokee.
So, if you are looking for the best off road performance, the Rubicon gives you both sway bar disconnect and axle lock options.
These two options are great for keeping your traction and your wheels on the ground.
Thermoelectric materials can directly convert heat into electricity as well as electricity into heat. Here is an interesting article review that briefly explains how researchers at RPI developed an easy and inexpensive process to make these materials using clever chemistry and nanostructured components. The full explanation of this work was published in a paper in Nature Materials. In addition to being easier and more cost effective, the new process can also result in higher energy conversion efficiencies. Thermoelectric materials can for example be used to recuperate energy lost in the form of heat (car exhaust for instance) back into useful electrical energy.
