- Ambient energy harvesting has great potential to contribute to sustainable development and address growing environmental challenges. Converting waste energy from energy-intensive processes and systems (e.g. combustion engines and furnaces) is crucial to reducing their environmental impact and achieving net-zero emissions. Compact energy harvesters will also be key to powering the exponentially growing smart devices ecosystem that is part of the Internet of Things, thus enabling futuristic applications that can improve our quality of life (e.g. smart homes, smart cities, smart manufacturing, and smart healthcare). To achieve these goals, innovative materials are needed to efficiently convert ambient energy into electricity through various physical mechanisms, such as the photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, and radiofrequency wireless power transfer. By bringing together the perspectives of experts in various types of energy harvesting materials, this Roadmap provides extensive insights into recent advances and present challenges in the field. Additionally, the Roadmap analyses the key performance metrics of these technologies in relation to their ultimate energy conversion limits. Building on these insights, the Roadmap outlines promising directions for future research to fully harness the potential of energy harvesting materials for green energy anytime, anywhere.

Konferensbidrag (refereegranskat)abstract
- The LEGaTO project leverages task-based programming models to provide a software ecosystem for Made in-Europe heterogeneous hardware composed of CPUs, GPUs, FPGAs and dataflow engines. The aim is to attain one order of magnitude energy savings from the edge to the converged cloud/HPC, balanced with the security and resilience challenges. LEGaTO is an ongoing three-year EU H2020 project started in December 2017.

- The accumulation of Cr(VI)will cause mutagenic and carcinogenic effects on humans. Therefore, the standard regulations have been governed by the EPA to control the chromium content in the effluent and drinking water and have made it mandatory [1]. For the better recovery of the adsorbent; Magnetic nano particle based phosphorene titanium nano tubes were used for the first time in action which has been proven to be superior for the Chormium pollutants. MNP-PN-TNT (Magnetic nanoparticle-Phosphorene-Titanium nano tubes)was synthesized from hydrothermal method in this study. The prepared material is used for effective removal of Cr(VI)from the water by adsorption technique in acidic environment. The adsorption capacity was found to be 35 mg g −1 at the initial concentration of 50 mg L −1 maintainingthe temperature under 45 °C. The optimal operation condition is under pH 9, temperature of 25 °C, and dosage of 0.8 g L −1 obtained from RSM (Response Surface Methdology). The adsorption process of MNP-PN-TNT is conformed with a pseudo-second-order kinetic model. Cr(VI)adsorption behavior with MNP-PN-TNT, is spontaneous from the results of thermodynamics analysis. The adsorption mechanism of Cr(VI)with MNP-PN-TNT was evident by O1s, C1s, Cr 2p, Ti 2p, Fe 2p and P 2p of XPS. Cr(VI)is adsorbed with MNP-PN-TNT, in randomness during the adsorption process.

- This paper investigates key determinants of business performance in China's video industry in the era of digital convergence. Specifically, we analyze China's OTT (over-the-top) service providers and cable operators based on the perspective of an industry platform, which acts as the core module of a business ecosystem and is capable of facilitating and coordinating interdependence among different agents. Panel data models are established to empirically explore what factors impact the performance of these two types of players. The findings demonstrate that both platform use and the size of an installed base are crucial for the determinants of the performance of OTT service providers and cable operators. An online video platform can also benefit from an increasing proportion of mobile viewers by implementing a multi-screen strategy. Further, an OTT service provider can profit from the interaction between its installed base and UGC (user-generated content), while cable operators can take advantage of positive feedback between their demand side and supply side.
