“…Mechanical experiments give important information on the effect of the nanofibers, but other techniques are also used to further investigate their working mechanisms and are here mentioned. Most of the papers use SEM images to study and compare virgin and nanomodified fractured surfaces; other common techniques used for the same purpose, and mentioned in this review are acoustic emissions [104], X-ray spectroscopy [82], high-resolution transmission electron microscopy [105] and transmission electron microscopy [13].…”

In the last few decades nanofibers have been developed and introduced in a vast number of industrial and research applications. One of their most effective use is as interleaved reinforcement for composite laminate materials against delamination. Nanofibrous mats have the ideal morphology to be embedded between two plies of a laminate, and a vast and deep research has been carried out investigating their effect on the global behaviour of a composite laminate. This review is the first of its kind to date which presents a detailed state-ofthe-art on the effect of nanofibrous interleaves into composite laminates with focus on the mechanical performances and behaviours of nanomodified materials. A detailed description of the working mechanisms of the nanointerleave under different load cases is presented, and a comparative analysis between papers in literature will provide readers with a powerful tool to understand and use nanofibers for reinforcing purposes.

“…Therefore, hydrothermally prepared pyroelectric nanofibers behave as ferro-/pyroelectric effect without undergoing poling process [24]. It has been reported that BaTiO3 nanofiber has a high piezoelectric coefficient (d33) of ~45 pC/N [16,25]. Figure 3 shows the temperature curve of one cold-hot cycle excitation.…”

A pyro-electro-chemical catalytic dye decomposition using lead-free BaTiO 3 nanofibers was realized under room-temperature cold-hot cycle excitation (30-47 • C) with a high Rhodamine B (RhB) decomposition efficiency~99%, which should be ascribed to the product of pyro-electric effect and electrochemical redox reaction. Furthermore, the existence of intermediate product of hydroxyl radical in pyro-electro-chemical catalytic process was also observed. There is no significant decrease in pyro-electro-chemical catalysis activity after being recycled five times. The pyro-electrically induced pyro-electro-chemical catalysis provides a high-efficient, reusable and environmentally friendly technology to remove organic pollutants from water.

In the coming era of the internet of things (IoT), wireless sensor networks that monitor, detect, and gather data will play a crucial role in advancements in public safety, human healthcare, industrial automation, and energy management. Batteries are currently the power source of choice for operating wireless network devices due to their ease of installation; however, they require periodic replacement due to capacity limitations. Within the scope of the IoT, battery maintenance of the trillion sensor nodes that may be implemented will be practically infeasible from environmental, resource, and labor cost perspectives. In considering individual self-powered sensor nodes, the idea of harvesting energy from ambient vibrations, heat, and electromagnetic waves has recently triggered noticeable research interest in the academic community. This paper gives an overview of energy harvesting materials and systems. Three main categories are presented: piezoelectric ceramics/polymers, magnetostrictive alloys, and magnetoelectric (ME) multiferroic composites. State-of-the-art harvesting materials and structures are presented with a focus on characterization, fabrication, modeling and simulation, and durability and reliability. Some perspectives and challenges for the future development of energy harvesting materials are also highlighted.
