Somenath Mitra, distinguished professor of chemistry and environmental science, was awarded a patent last month for a next-generation water desalination and purification technology that uses uniquely absorbent carbon nanotubes ...
A new material changes its conductivity depending on the concentration of CO2 in the environment. The researchers who developed it have utilized the material to produce a miniature, simply constructed sensor.
Over geologic time, the work of rain and other processes that chemically dissolve rocks into constituent molecules that wash out to sea can diminish mountains and reshape continents.
Coating engine components with hard carbon reduces friction to almost zero – a development that could save billions of liters of fuel worldwide every year. Now researchers have developed a new laser method to apply the ...
A group of nine PhD students from the Department of Earth and Environmental Sciences at Columbia University has just arrived in Exuma, The Bahamas, for a week-long field trip.
The widest global effort yet to gauge citizens' views on climate change showed 79 percent to be "very concerned" about its effects, but less than half support a carbon tax to curb emissions, organisers said Sunday.
Japan may find itself the odd man out when Prime Minister Shinzo Abe presents his government's blueprint for combating climate change at this weekend's summit of the world's leading industrialized democracies.
The world community has rallied around the goal of limiting global warming to two degrees Celsius (3.6 degrees Fahrenheit), but how to get there is becoming a headache.
As the ocean absorbs atmospheric carbon dioxide (CO2) released by the burning of fossil fuels, its chemistry is changing. The CO2 reacts with water molecules, lowering the ocean's pH in a process known as ocean acidification. ...
Scientists have adapted a process normally used to make bioplastic, to remove carbon from wastewater, slashing the amount of energy needed for the treatment process.
