Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

open access: yesEnergy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

Bridging Flavour and Fragrance: A Behaviour‐Based Olfactory Pyramid for Whisky Maturation Inspired by Perfumery Principles

open access: yesFlavour and Fragrance Journal, EarlyView.
This framework transposes the perfumery olfactory pyramid to whisky maturation by sequencing aromas into top, heart, and base notes according to their temporal persistence. Using Log P as a behaviour‐based classification axis and oak macromolecules as natural fixative analogues, it proposes a behaviour‐based aromatic wheel bridging flavour chemistry ...
