Engineers Just Unveiled a New Blackest-Ever Material, Even Darker Than Vantablack
You might think you already know black – even super-black Vantablack, previously the blackest material known to science – but researchers just came up with a material that takes black to a new level of blackness. The new, as-yet-unnamed ultra-black material is made from vertically aligned carbon nanotubes (CNTs), microscopic carbon strings that are a little like a fuzzy forest of tiny trees, according to the team behind the project. And here's the rub – this CNT material can absorb more than 99.995 percent of incoming light, beating the 99.96 percent that Vantablack is able to absorb.
A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The device is essentially a large, specialized battery that absorbs carbon dioxide from the air (or other gas stream) passing over its electrodes as it is being charged.
Researchers have created a new system for removing carbon dioxide from a stream of air that can work at almost any concentration level, from power plant emissions to open air , according to MIT It absorbs carbon dioxide from a gas stream that passes over its electrodes as it's being charged up.
The Massachusetts Institute of Technology may have developed a new weapon in the fight against climate change. Researchers have created a new system forthat can work at almost any concentration level, from power plant emissions to open air, according to MIT News.
MIT said the new system requires less energy and money to operate than other methods, which require higher concentrations, such as those found in the flue emissions from fossil fuel-based power plants.
MIT Engineers Have Created The 'Blackest Black' To Ever Black
Move over, Vantablack. MIT engineers have developed a material they they claim is 10 times blacker than any other to date. In a blog post, MIT describes the material as being made from vertically aligned carbon nanotubes, which are microscopic carbon filaments. The engineers grew the carbon nanotubes on chlorine-etched aluminium foil, which then captured more than 99.995 per cent of incoming light in lab testing. For reference, Vantablack, the previous holder of the “blackest black” title, captures 99.965 per cent of light.

The device at the heart of the system behaves like a large battery. It absorbs carbon dioxide from a gas stream that passes over its electrodes as it's being charged up. It then blows out the pure carbon dioxide as it discharges.
The system's inner-workings are detailed further by the researchers -- MIT postdoc Sahag Voskian and professor T. Alan Hatton -- in a paper called, which was published this month n the journal Energy and Environmental Science.
"In my laboratories, we have been striving to develop new technologies to tackle a range of environmental issues that avoid the need for thermal energy sources, changes in system pressure or addition of chemicals to complete the separation and release cycles," Hatton told MIT News. "This carbon dioxide capture technology is a clear demonstration of the power of electrochemical approaches that require only small swings in voltage to drive the separations."
While operating, the device alternates between charging and discharging. During a charging cycle, fresh air blows through the system. During discharging, concentrated carbon dioxide blows through.
The research team has launched a company called Verdox to commercialize the system, which could have applications for the bottling of soft drinks and the creation of plant food.
