Researchers at Johns Hopkins Engineering have developed a benchtop prototype device designed to capture carbon dioxide from the atmosphere by harnessing the unique interactions between electricity and indigo\u2014the iconic, inexpensive, and readily available dye used in blue jeans. The team\u2019s innovative design, described in \"A<\/a><\/p>\n

Advanced Functional Materials<\/a><\/em>, presents a cost-efficient alternative to traditional carbon capture methods. Working in a simulated environment resembling a factory\u2019s exhaust stream, the researchers showed promising results. \u201cOur tests showed that this indigo-based system operates at 80% of the maximum theoretical efficiency,” explains Krish Jayarapu, a third-year student in chemical and biomolecular engineering<\/a>, who worked with Assistant Professor Yayuan Liu<\/a> on the prototype.<\/p>\n

\u201cIndigo\u2019s chemical properties allow it to latch onto carbon dioxide when electricity is applied and then release it when the current is reversed.\u201d<\/p>\n

The new prototype device\u2019s electrical process achieves optimal carbon capture efficiency while using low-cost materials and a modular design, making it scalable for both small devices and large industrial applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
