Mattershift scales up CNT membranes; potential for zero-carbon fuels for less than fossil

Green Car Congress

Startup Mattershift says it has achieved a breakthrough in making carbon nanotube (CNT) membranes at large scale. The paper is a characterization study of commercial prototype carbon nanotube (CNT) membranes consisting of sub–1.27-nm-diameter nm-diameter CNTs traversing a large-area nonporous polysulfone film.

Study finds global carbon emissions reached 10 billion tonnes in 2010

Green Car Congress

Global carbon dioxide emissions from burning fossil fuels have increased by 49% in the last two decades, according to the latest figures from the Global Carbon Project. Total emissions—including fossil fuel combustion, cement production, deforestation and other land use emissions—reached 10 billion tonnes of carbon (36.7

Study finds Antarctic icebergs play a previously unknown role in global carbon cycle, climate

Green Car Congress

In a finding that has global implications for climate research, scientists have discovered that when icebergs cool and dilute the seas through which they pass for days, they also raise chlorophyll levels in the water that may in turn increase carbon dioxide absorption in the Southern Ocean.
