Sentences with phrase «carbon nanofibers»
Carbon nanofibers are tiny threads made of carbon atoms. They are incredibly thin and lightweight, but also very strong. They have various useful properties and are used in various applications such as making materials stronger, conducting electricity, and removing pollutants from the air or water. Full definition
Today in Nano Letters, the group presents a process that turns atmospheric CO2 into carbon nanofibers similar to valuable materials used in industries such as aerospace, construction, and electronics.

But now, a study from Ohio State University found that the life - cycle environmental impacts of carbon nanofiber can be as much as 100 times worse than traditional materials, and another study from the University of Illinois at Chicago shows that loose regulations in nanomaterial manufacturing could mean greater environmental burdens than conventional manufacturing.
«Spinning a lighter, safer electrode: Researchers develop solid - state, free - standing carbon nanofiber supercapacitor.»
So instead of a flammable electrolyte solution, the device designed by Vibha Kalra, PhD, a professor in Drexel's College of Engineering, and her team, used a thick ion - rich gel electrolyte absorbed in a freestanding mat of porous carbon nanofibers to produce a liquid - free device.
And researchers in the United States have just come up with a new process to use sunlight to make high - strength and light carbon nanofibers, which are used in consumer products and building materials.
In particular, he and his team hope STEP could provide a less expensive way to make carbon nanofibers.

Until scientists learn to spin STEP's carbon nanofibers into long commercially usable fibers, he says, it's too early to hail the process as an environmental breakthrough.
Researchers have invented a process that turns atmospheric carbon dioxide into carbon nanofibers.
The team found that with the right combination of metals, voltage, and temperature, STEP's coulombic efficiency (a classic measure of chemical yield used to determine how efficiently the product is made) hovered around 95 %, meaning that in STEP's case, 95 % of the current worked toward producing the carbon nanofibers, and only 5 % powered other side reactions.
