IAAM recognizes the contribution of scientists towards the advancement of materials to global excellence with the ‘Researcher of the year’ award every year. Prof. Zhong Lin (Z. L.) Wang from Georgia Tech., USA and Prof. T. Venkatesan from Nano Core Research Center at National University of Singapore were recognized with this prestigious award in 2017 and 2018, respectively. This year, the award is presented to eminent physicist Prof. Enge Wang, Vice President of Chinese Academy of Sciences (CAS) and President Emeritus of Peking University, China, for his contribution towards the nanotechnology research and innovations. Advanced Materials Letters feels very honored and privileged to confer upon him the ‘Researcher of the Year’ award and dedicate the cover photo of December 2019 issue for his several years of diligence and uncountable achievements.

Regarding modern, daylight-flooded buildings with large window façades, appropriate shading systems to improve the energy consumption of climate controlling systems are becoming more relevant. Building envelopes contribute largely to the temperature control and should be at best installed on the outside to prevent the interior from heating up. Preferably, those systems work with minimum maintenance and maximum robustness, covering as much of the window area as possible. Previous shading systems were mostly based on rigid-body mechanisms using error-prone joints. Components, whose movability is achieved by a local compliance of the material, offer a way to avoid the usage of mechanical joints. Within this paper, a new fiber-reinforced plastic (FRP) façade shading demonstrator called “Flexafold” is presented. Its opening and closing movement are controlled by pneumatic cushions which are integrated directly into the laminate set-up. The Flexafold shows thereby the possibility of producing self‑supporting, adaptive FRP components whose actuators are integrated into the component and thus protected in exterior applications. The functional principles and components of Flexafold, e.g. the locally compliant FRP material, the folding pattern and the integrated actuator system, are explained within this paper. Furthermore, a comparison to existing adaptive façade shading systems “flectofin®” and “Flectofold” is given. © VBRI Press
