Ships, ports and particulate air pollution - an analysis of recent studies [PDF]

open access: yes, 2011
The duration of use is usually significantly longer for marine vessels than for roadside vehicles. Therefore, these vessels are often powered by relatively old engines which may propagate air pollution.

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

open access: yesAdvanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Methodological Design Optimization of a Marine LNG Internal Combustion Gas Engine to Burn Alternative Fuels

open access: yesJournal of Marine Science and Engineering, 2023
Marine emission policies are becoming more demanding; thus, ship propulsion and power generation technologies need to be adapted to current scenarios. LNG is already considered to be a transition fuel, and new alternative marine fuels are emerging.

Marine fuels after 2020 III

open access: yesPaliva, 2021
On 1st January 2020, a drastic change came into force to reduce the maximum permitted sulphur content of marine fuels from 3.5 % wt. to 0.5% wt. for the deep sea and oceans. This change had an impact not only on the shipping industry, but also on the entire refining sector, be it oil marketers, refineries, traders and manufacturers of fuels and end ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...
