In this work, the fabrication and properties of ultraviolet-sensing films based on hybrid nanomaterials, containing graphene nanoplatelets (GNP) as signal transducer and DNA as UV-sensitive element, are investigated. The sensor components are prepared by sonication-driven non-covalent assembly and are embedded in a polymer matrix for enhanced adhesion on several types of space-grade materials and structures. We show that these nanomaterial sensing films can be used to monitor the effects of UV radiation exposure in real time.

Public educational systems operate thousands of buildings with vastly different characteristics in terms of size, age, location, construction, thermal behavior and user communities. Their strategic planning and sustainable operation is an extremely complex and requires quantitative evidence on the performance of buildings such as the interaction of indoor-outdoor environment. Internet of Things (IoT) deployments can provide the necessary data to evaluate, redesign and eventually improve the organizational and managerial measures.
