Special Issue Information

Dear Colleagues,

Under the dual pressures of global ecological environment deterioration and an increasing shortage of traditional fossil energy, utilizing renewable energy has become an important energy strategy for every country in the hopes of achieving social sustainability. Harvesting renewable energies from our ambient environments through the development of novel smart nanomaterials and micro/nanoscale energy technologies is of great practical significance. The emergence of nanogenerators, which can effectively harvest the environmental mechanical energy needed to generate electricity, provides a promising route to sustainable energy. The rapid development of nanogenerator technologies has gradually improved our understanding of energy harvesting. Also, new smart nanomaterials with new nanostructures need to be explored for nanogenerator systems in order to enhance the output performance and efficiency of nanogenerators.

This Special Issue on “Nanotechnology and Nanomaterials for Energy Applications” aims to cover recent achievements in the fields of novel nanomaterial fabrication and characterization as well as nanotechnology applications in environmental energy harvesting and self-powered systems.

The issue of wellbore instability poses a significant challenge in the current exploration of shale gas reservoirs. Exploring more efficient shale stabilizers has always been a common goal pursued by researchers. In this paper, a novel shale stabilizer, denoted as ANS, was prepared by employing a silane-coupling modification method to graft (3-Aminopropyl) triethoxysilane (APTES) onto the surface of nano-silica. The structure of ANS was characterized through Fourier transforms infrared spectroscopy (FT-IR), thermo-gravimetric analysis (TGA), and particle size tests (PST). The shale stabilizing properties of ANS were evaluated through tests such as pressure penetration, BET analysis, hydration expansion and dispersion. Furthermore, the interaction between ANS as a shale stabilizer and clay was explored through clay zeta potential and particle size analysis. The results indicated that ANS exhibited a stronger plugging capability compared to nano-silica, as evidenced by its ability to increase the shale pressure penetration time from 19 to 131 min. Moreover, ANS demonstrated superior hydration inhibition compared to commonly used KCl. Specifically, it reduced the expansion height of bentonite from 8.04 to 3.13 mm and increased the shale recovery rate from 32.84% to 87.22%. Consequently, ANS played a dual role in providing dense plugging and effective hydration inhibition, contributing significantly to the enhancement of wellbore stability in drilling operations. Overall, ANS proved to be a promising shale stabilizer and could be effective for drilling troublesome shales. Full article
