Nov. 5, 2020 —Scientists have discovered a spongy form of calcium carbonate (CaCO3), a material found in limestone, chalk, marble, and the shells of mussels and other shellfish. While most forms of calcium ...
Apr. 8, 2021 —A group of researchers has taken advantage of different erosion rates and investigated how uplift and erosion of rocks determine the balance of carbon emissions and uptake. The surprising result: at ...
June 16, 2021 —A researcher has firsthand experience with the frustrations of oil production. He spent nine years as a hydraulic fracturing engineer with operating and service companies. A few years ago, he started ...
Oct. 7, 2021 —A new kind of concrete could reduce emissions from the construction industry. Calcium carbonate concrete is made from waste concrete and carbon dioxide from the air or industrial exhaust gases. It ...
Dec. 1, 2021 —Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. They are responsible for half of the limestone produced in the oceans and ...
Aug. 18, 2021 —Researchers have developed a climate-friendly alternative to conventional cement. Carbon dioxide (CO2) emissions can be reduced during production by up to two thirds when a previously unused ...
Oct. 21, 2020 —Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the Earth's history and its ...
Mar. 25, 2021 —A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years. ...
Apr. 12, 2021 —Researchers have discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings will allow scientists to better estimate the ...
Dec. 17, 2020 —Researchers have shed new light on the formation mechanisms of a rare earth-bearing mineral that is in increasingly high demand across the globe for its use in the green energy and tech industries. ...
