Researchers at the Georgia Institute of Technology have devised a method for using an origami-based structure to create radio frequency filters that have adjustable dimensions, enabling the devices to change which signals they block throughout a large range of frequencies.
A paper detailing a type of origami tube that is strong and reconfigurable will be recognized in May as one of the best studies published in the Proceedings of the National Academy of Sciences in 2015. The editors of the journal have selected the research for the Cozzarelli Prize, an annual award for scientific excellence and originality.
Researchers from the University of Illinois at Urbana-Champaign, the Georgia Institute of Technology and the University of Tokyo have developed a new “zippered tube” configuration that makes paper structures stiff enough to hold weight yet able to fold flat for easy shipping and storage. Their method could be applied to other thin materials, such as plastic or metal, to transform structures ranging from furniture and buildings to microscopic robots.
By combining information about power plant operation with real-time air quality predictions, researchers have created a new capability to minimize the human health effects of air pollution resulting from electric power generating facilities. The Air Pollutant Optimization Model, described in the journal Proceedings of the National Academy of Sciences, provides a new approach for reducing the health effects of ozone and fine particulate pollution.
