Carbon capture and storage CCS or carbon capture and sequestration  is the process of capturing emitted carbon dioxide CO 2 , transporting it to a storage site, and depositing it where it will not enter the atmosphere. Usually the CO 2 is captured from large point sources , such as a chemical plant or biomass power plant , and then stored in an underground geological formation. The aim is to prevent the release of CO 2 from heavy industry with the intent of mitigating the effects of climate change. CO 2 can be captured directly from an industrial source, such as a cement kiln , using a variety of technologies; including absorption , adsorption , chemical looping , membrane gas separation or gas hydration. Most projects are industrial.
Radiocarbon Dating and Archaeology
Carbon dating accuracy called into question after major flaw discovery
Ranging from the very crude to the highly sophisticated, batteries come in a plethora of variety. Batteries in short are electrochemical cells that produce a current of electricity via chemical reactions. More specifically, batteries produce electrical energy from oxidation-reduction reactions. A collection of electrochemical cells wired in series is properly called a battery. A flashlight battery is really a single electrochemical cell, while a car battery is really a battery since it is three electrochemical cells in series. Electrochemical cells have been in use longer than what was once thought. Consisting of a copper cylinder, an iron rod, an asphalt stopper, and a small earthenware jar, the Baghdad Battery was filled with an unknown electrolytic solution and may have been used for electroplating.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in Radiocarbon dating is based on the fact that radiocarbon 14 C is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
