2. Çatalhöyük - Wikipedia

   en.wikipedia.org/wiki/Çatalhöyük

   Calibrated carbon-14 dates for Çatalhöyük, as of 2013 [1]. Çatalhöyük (English: Chatalhoyuk / ˌ tʃ ɑː t ɑː l ˈ h uː j ʊ k / cha-tal-HOO-yuhk; Turkish pronunciation: [tʃaˈtaɫhœjyc]; also Çatal Höyük and Çatal Hüyük; from Turkish çatal "fork" + höyük "tumulus") is a tell (a mounded accretion due to long-term human settlement) of a very large Neolithic and Chalcolithic ...

3. Graphene - Wikipedia

   en.wikipedia.org/wiki/Graphene

   Graphene is the only form of carbon (or solid material) in which every atom is available for chemical reaction from two sides (due to the 2D structure). Atoms at the edges of a graphene sheet have special chemical reactivity. Graphene has the highest ratio of edge atoms of any allotrope. Defects within a sheet increase its chemical reactivity ...

4. Allotropes of carbon - Wikipedia

   en.wikipedia.org/wiki/Allotropes_of_carbon

   A vapor of carbon-containing molecules is injected into the zeolite, where the carbon gathers on the pores' walls, creating the negative curve. Dissolving the zeolite leaves the carbon. A team generated structures by decorating the pores of a zeolite with carbon through a Monte Carlo method. Some of the resulting models resemble schwarzite-like ...

5. Amorphous carbon - Wikipedia

   en.wikipedia.org/wiki/Amorphous_carbon

   According to the researchers, Q-carbon exhibits a random amorphous structure that is a mix of 3-way (sp 2) and 4-way (sp 3) bonding, rather than the uniform sp 3 bonding found in diamonds. [7] Carbon is melted using nanosecond laser pulses, then quenched rapidly to form Q-carbon, or a mixture

6. Ottoman (furniture) - Wikipedia

   en.wikipedia.org/wiki/Ottoman_(furniture)

   An ottoman is a piece of furniture. [1] Generally, ottomans have neither backs nor arms. They may be an upholstered low couch or a smaller cushioned seat used as a table, stool or footstool. The seat may have hinges and a lid for the inside hollow, which can be used for storing linen, magazines, or other items, making it a form of storage ...

7. Carbon-based life - Wikipedia

   en.wikipedia.org/wiki/Carbon-based_life

   Carbon's widespread abundance, its ability to form stable bonds with numerous other elements, and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables it to serve as a common element of all known living organisms. In a 2018 study, carbon was found to compose approximately 550 billion tons of all life on ...
