Transportation and power generation have historically relied upon Internal Combustion Engines (ICEs). However, because of environmental impact inefficiency, considerable research has been devoted to improving their performance. Alternative fuels are necessary concerns the depletion non-renewable fuel stocks. Biodiesel potential reduce emissions improve sustainability when compared diesel fuel. Several researchers examined using nanofluids increase biodiesel performance in internal combustion engines. Due thermal physical properties, nanoparticles a host fluid engine efficiency. This comprehensive review examines three key areas for ICE efficiency: as an alternative fuel, application nanofluids, artificial intelligence (AI)/machine learning (ML) integration. The integration AI/ML nanoparticle-infused offers exciting possibilities optimizing production processes, enhancing article first discusses, benefits concerning environment various difficulties associated with its usage. then explores effects characteristics IC engines, aiming know on After that, this discusses utilization techniques biodiesel-nanofluid process. sheds light ongoing efforts make technology more environmentally friendly energy-efficient by examining current emerging patterns these fields. Finally, presents challenges future perspectives field, paving way improvement.

Despite progress in many countries, air pollution, and especially fine particulate matter pollution (PM2.5) remains a global health threat: over 6 million premature cardiovascular respiratory deaths/yr. have been attributed to household outdoor pollution. In this viewpoint, we identify present gaps monitoring regulation, how they could be strengthened future mitigation policies more optimally reduce impacts. We conclude that there is need move beyond simply regulating PM2.5 mass concentrations at central site stations. A greater emphasis needed on: new portable affordable technologies measure personal exposures particle mass; the consideration of submicron (PM1) quality standard; further evaluations effects by composition source. emphasize enable studies on exposure–health relationships underserved populations are disproportionately impacted but not sufficiently represented current studies.
