Quick response (QR) codes are becoming ubiquitous. When read by a cellphone, these small squares of black square dots provide additional details on a product, service or activity. Now, a team of scientists from two South Dakota universities has developed an ink from unique nanoparticles to print covert QR codes.
Hands-on engineering activities are being developed and tested that showcase how the Sanford Underground Research Facility operates. While much of the scientific research of the underground lab in Lead, South Dakota is quite esoteric and difficult to convey by way of hands-on activities, there is plenty of engineering related to the facility’s operation that is highly accessible and engaging for high school, middle school, and even elementary school students.
Approximately 50 students took part in Oglala Lakota College’s Math Camp held at Pejuta Haka College Center in Kyle, SD in August 2011. OLC’s Math & Science department hosted the third annual event open to 6th grade through college level students.
Outcome/Impact/benefits: This research has focused on the development and direct write printing of thin polymer films impregnated with silver and upconverting nanoparticles. Such thin polymer films could be used for luminescent solar concentrators, as well as having possible applications in security printing and energy harvesting.
