“…Lastly, the bioleaching conditions should be optimized as they affect the biological activities of microorganisms. Novel bioreactors should be built, such as light induced systems and energy harvesting systems [ 91 , 92 ]. The addition of various catalysts also needs to be tested, which might help improve bioleaching efficiency.…”

The rapid pace of innovations and the frequency of replacement of electrical and electronic equipment has made waste printed circuit boards (WPCB) one of the fastest growing waste streams. The frequency of replacement of equipment can be caused by a limited time of proper functioning and increasing malfunctions. Resource utilization of WPCBs have become some of the most profitable companies in the recycling industry. To facilitate WPCB recycling, several advanced technologies such as pyrometallurgy, hydrometallurgy and biometallurgy have been developed. Bioleaching uses naturally occurring microorganisms and their metabolic products to recover valuable metals, which is a promising technology due to its cost-effectiveness, environmental friendliness, and sustainability. However, there is sparse comprehensive research on WPCB bioleaching. Therefore, in this work, a short review was conducted from the perspective of potential microorganisms, bioleaching mechanisms and parameter optimization. Perspectives on future research directions are also discussed.

“…What we expect is to make full use of any available resources in the environment where the device is deployed. Therefore, the idea of a self-powered system is proposed, which is one of the most feasible schemes for low power electronic devices by effectively acquiring environmental energy [10][11][12][13][14][15][16][17][18].…”

By seamlessly integrating the wearing comfortability of textiles with the biomechanical energy harvesting function of a triboelectric nanogenerator (TENG), an emerging and advanced intelligent textile, i.e., smart textile TENG, is developed with remarkable abilities of autonomous power supply and self-powered sensing, which has great development prospects in the next-generation human-oriented wearable electronics. However, due to inadequate interface contact, insufficient electrification of materials, unavoidable air breakdown effect, output capacitance feature, and special textile structure, there are still several bottlenecks in the road towards the practical application of textile TENGs, including low output, high impedance, low integration, poor working durability, and so on. In this review, on the basis of mastering the existing theory of electricity generation mechanism of TENGs, some prospective strategies for improving the mechanical-to-electrical conversion performance of textile TENGs are systematically summarized and comprehensively discussed, including surface/interface physical treatments, atomic-scale chemical modification, structural optimization design, work environmental control, and integrated energy management. The advantages and disadvantages of each approach in output enhancement are further compared at the end of this review. It is hoped that this review can not only provide useful guidance for the research of textile TENGs to select optimization methods but also accelerate their large-scale practical process.

“…[4][5][6] For instance, lithium batteries (LIB) and supercapacitors (SC) are ubiquitous; however, limited shelflife, lack of flexibility in integrated smart electronics, and disposal hazards may compromise their all-weather demand in the long run. 7,8 Several alternatives have already sprung up to meet the demand for green, flexible and stable power sources. 9 Triboelectric nanogenerators (TENG) are most notable in terms of converting ambient mechanical energy to scalable electrical output and have already been hailed as promising alternatives Despite the fact that commercial rubbers are highly desirable in terms of mechanical strength, thermal & chemical stability, their involvement in nanoengineered triboelectric generator (TENG)-based tactile devices is practically non-existent.…”
