Roadmap on energy harvesting materials

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

Effect of calcination temperature on cobalt substituted cadmium ferrite nanoparticles

The Cd0.9Co0.1Fe2O4 nanoparticles are synthesized using chemical co-precipitation method. The as-prepared samples are calcinated at 300 and 600 degrees C for 2 h. The thermal effects on structural, morphological and magnetic properties are reported. The X-ray diffraction data confirm the formation of single-phase cubic spinel structure. The Surface morphology and compositional features are studied using SEM with EDX and TEM measurements. The Magnetic properties of samples are evaluated using vibrating sample magnetometer. The magnetic properties, like saturation magnetization and coercivity are increases with increasing calcination temperature. The enhancement is attributed to the transition from a multi-domain to a single-domain nature. From the FTIR spectra, it is confirmed that the vibrations of tetrahedral and octahedral complexes corresponds to absorption bands at 590 cm(-1) (nu(1)) and 460 cm(-1) (nu(2)) respectively. The particle size enhances significantly with increasing the calcinated temperature.ope
