The deposition properties of tetrahedral amorphous carbon coatings deposited on piston ring: Molecular dynamics simulation

Journal of Applied Physics, Journal Year: 2024, Volume and Issue: 135(6)

Published: Feb. 13, 2024

The tetrahedral amorphous carbon (ta-C) coatings are deposited on piston rings to improve the tribological property of ring-cylinder liner system internal combustion engines. deposition parameters optimized by molecular dynamics simulation reduce cost coatings’ fabrication. ta-C with higher sp3 fraction, lower friction coefficient, and superior anti-wear properties achieved optimizing incident energy substrate temperature atoms. second nearest-neighbor modified embedded-atom method potential Tersoff used describe interatomic interactions. effects atoms discussed. numerical results show that high density, good interface mixing obtained, improved.

Decarbonizing the Transportation Sector: A Review on the Role of Electric Vehicles Towards the European Green Deal for the New Emission Standards

Air, Journal Year: 2025, Volume and Issue: 3(2), P. 10 - 10

Published: April 1, 2025

The transportation sector has a significant impact on climate change, as it is responsible for 20% of the global greenhouse gas (GHG) emissions. This paper evaluates role electric vehicles (EVs) in achieving Europe’s ambitious target carbon neutrality by 2050. limitations internal combustion engines (ICEs) along with recent advancements, such Euro 6 standards, are examined pseudo–lifecycle analysis (pseudo-LCA). While ICEs remain cost-effective initially, their higher long-term cost and environmental make them unsustainable. benefits EVs, including high energy efficiency, minimal maintenance, reduced GHG emissions, stated. However, challenges range limitations, charging infrastructure, battery production persist. Hybrid (HEVs) highlighted transitional technologies, offering improved thermal efficiency enhancing air quality both urban rural areas. extends to use alternative fuels, bioethanol, biodiesel, hydrogen. These provide interim solutions but face scalability sustainability issues. Policy interventions, subsidies, tax incentives, investments renewable energy, crucial factors EV adoption. As EVs pivotal decarbonization, integrating addressing systemic essential sustainable transition.
