Performance, emissions, and lubricant oil analysis of a marine diesel engine powered by raw Schizochytrium sp. and its blends

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 136-154, January/February 2026.
Abstract Microalgae oil (MAO), a third‐generation biofuel, can support global transportation fuel demand as a fossil fuel substitute. Schizochytrium sp. MAO is particularly promising for direct use in compression ignition (CI) engines, especially in the marine sector, due to its adaptability and high oil yield.

The Synergistic Antiwear Performances of Organic Titanium Compounds Containing Sulfur with Borate Ester Additive

open access: yesJournal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Two oil‐soluble organic titanium compounds (OTCs) such as titanium dialkyldithiocarbamate (TiDDC) and sulfurized titanate (TiS) were synthesized and identified by Fourier‐transform infrared spectroscopy (FTIR). The antiwear and extreme pressure properties of TiDDC or TiS with borate ester containing nitrogen (BNO) additive in mineral base oils were ...
