Special Issue Information

Dear Colleagues,

Over the last 40 years, nanotechnology has enabled many important scientific discoveries as materials at the nanoscale present fascinating properties compared to their bulk counterparts. Nanotechnology has been instrumental in achieving higher efficiency in energy systems, allowing better utilization of incident power with tunable optical, electrical, mechanical, and magnetic properties. These nanomaterials and nanostructures have been fabricated with various techniques, from bottom-up approaches such as chemical synthesis to top-down approaches such as lithography. Developments in spectroscopy and theoretical modeling techniques have further pushed the boundaries of nanomaterial exploration.

This Special Issue aims to present and disseminate the most recent advancements in material development, design, experimentation, theory, and modeling of energy systems based on nanotechnological research and development.

Topics of interest for publication include but are not limited to the application of nanotechnology for:

  • Fuel cells;
  • Solar cells;
  • Batteries;
  • Steam generation;
  • Waste heat recovery;
  • High-efficiency lighting;
  • Hydrogen generation;
  • Heating and cooling buildings;
  • Energy storage;
  • Piezoelectricity.

In this study, the effects of pristine carbon nanotubes (CNTs), sodium dodecylbenzene sulfonate (SDBS), and diesel blends on the ignition delay and burning rate are examined experimentally. For this purpose, single-droplet combustion tests were conducted in a combustion system for 21 days using CNTs at concentrations of 50 ppm and 100 ppm, which were dispersed in Colombian commercial diesel and stabilized by SDBS. Videos of the diesel droplet burning were obtained using a high-speed camera, and the Shadowgraph optical technique was used to observe the development of the droplet size during combustion. Thus, records of the process were collected, and the treatment was carried out using a MATLAB algorithm. The measurements and processing were carried out along with a stability study, which included measurements of dynamic light scattering (DLS), pH, potential Zeta, and properties such as thermal conductivity and surface tension. The results demonstrated that the temporal stability has a direct impact on the single-droplet combustion tests because a concentration of CNTs of 100 ppm showed a higher stability than those achieved by 50 ppm. Consequently, improvements were found with a concentration of 100 ppm—for instance, the thermal conductivity increased by about 20%, the ignition delay time increased by 16.2%, and the burning rate increased by 30.5%.
