“…Compared with the M10, the M10A100's in-cylinder pressure and peak heat release rate have been increased by a maximum of 3.6% and 7.12%. This is because the adhesion bond between fuel molecules and Al2O3 nanoparticles produces denser droplets and ligaments, which improves the atomization effect of methanol-based nanofluid fuel injection [13] . In addition, Al2O3 particles can improve the thermal conductivity of fuel, and accelerate the evaporation and mixing of fuel and air [14] .…”

With the increasingly strict domestic emission regulations, how to reduce diesel emission without affecting its output power has become a hot and important research topic. Due to their unique physical and chemical properties, the combined use of methanol and Al2O3 nanoparticles plays a unique role in promoting combustion and reducing emissions. In this study, Al2O3 methanol nanofluid fuel was injected into the inlet and diesel fuel was injected into the cylinder to explore the influence of Al2O3 nanoparticles on the performance, combustion and emissions of diesel methanol dual fuel (DMDF) entered. The experienced results showed that with the addition of Al2O3 nanoparticles in methanol, the peak pressure and heat release rate in the cylinder of the diesel engine were improved, the combustion delay period and the combustion duration were shortened, the fuel consumption rate was reduced by up to 10.8%, and the braking thermal efficiency was increased by 12.11% at most. With the addition of Al2O3 nanoparticles, NOx, CO, HC and soot ratio emissions of the engine were reduced, among which the NOx reduction ratio was small, and the maximum reduction ratio of the last three was 28.82%, 83.33% and 29.27% respectively.

“…Nanocatalysts are improving the efficiency of many conversion processes in petroleum processing industries [92]. Moreover, car fuel consumption can be reduced by adding metallic nanoparticles to fuel, which ensure more efficient combustion [93]. Already described CNTs have proved effective as a low-temperature adsorbents for carbon dioxide (CO 2 ) capture from power plant flue gas [94].…”

Nanoscience and nanotechnology are already improving our lives in numerous ways. The aim of this paper is to give an insight into the vast array of their potential future uses, as well as current applications, and present the major breakthroughs, which made their development possible. A special section is reserved for the development in the field of microelectronics, which is facing numerous challenges due to the downsizing of devices to the nanometre level. Current situation in microelectronics industry and predictions for the next few years are presented. Furthermore, the use of nanotechnology and future prospects in the fields of medicine, energetics, environmental protection and transport are described. A significant part of this paper is devoted to the field of electronics and information technology, where some potential nanotechnological solutions for the challenges of microelectronics are implied. The use of carbon nanotubes in logic circuits and memory applications is presented. The basic principle of single-electron transistor is also described. Basic concepts of the use of spintronics in magnetoresistive random access memory (MRAM) structures are explained. Memristor is also presented as an important future prospect. In the last part, the investments in nanotechnology and nanoscience under the funding programmes of European Union are presented, followed by some predictions of these fields' future development. However, the review paper focuses only on positive effects of the use of nanotechnology, and thus does not discuss its possible negative impact on public health and environment.

“…Nanofluid addition not helps to improve the thermal conductivity of the vehicle engine, but also helps to reduce pollutant emissions [75,76]. An experimental study [75] was performed by adding silver nanoparticles to pure diesel fuel. From the result evaluation, it was concluded that the inclusion of the nanomaterial greatly reduced the emission rates of NO x and CO by up to 13 and 20.5%, respectively [75].…”
