Latimer would also play a big role in developing Edison’s carbon filament light bulb. He would own two patents himself relating to the carbon filament at the heart of that bulb. In 1890 ...

This solved the problem of heating the filament in air and opened the search to non-metal materials. Edison identified carbon as the most suitable material, and his team worked to produce an evacuated ...

Previous bulbs had burned for a much longer 1,500 ... known as the Centennial Bulb (click to see a webcam of the lamp), is a dim carbon-filament bulb that’s been burning nearly continuously ...

Advancements in energy-efficient lighting technologies are key to reducing energy consumption and carbon emissions, driving ...

The MP4/1’s carbon-­fiber chassis ... lamp with a carbonized-paper filament in 1860, 19 years before Thomas Edison’s commercially viable light bulb. In 1958, at Union Carbide in Ohio, Roger ...

A broken light bulb can be dangerous in many ways ... Begin by cutting power to the light source. If the filament is still intact, use a pair of needle nose pliers to grip the glass base of ...

Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.

Carbon dioxide sinks Since 1750, continuously increasing anthropogenic CO 2 emissions and land-use change have perturbed the natural carbon cycle. Of the 9.1 Pg C yr −1 (1 Pg C = 1 petagram or ...

When it comes to energy policies, carbon capture, utilization and sequestration is one of the most controversial. The technology – where carbon is captured from industrial processes or from the ...

Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global ...

Dead organisms are broken down into smaller pieces by the process of decay. Organisms such as earthworms are involved in this process.

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. Radiocarbon dating, or carbon-14 dating, is a ...
