Blending Optimization on The Fuel Characterization of Sunflower Oil - Pentanol Binary Biofuel Blend

Journal of Engineering Technology and Applied Physics
Straight vegetable oil (SVO) such as Pure Sunflower Oil (PSO) is a possible alternative biofuel to petroleum diesel fuel because of its physical qualities identical to fossil fuel. However, the higher viscosity and density of PSO limits its direct use in

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

The Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5397-5408, October 2026.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Exergy‐Based Performance Analysis and Optimization of Autonomous Fuel Cell‐Based Energy Systems With Solid Oxide and Proton Exchange Membrane Fuel Cells Fed by Biogas of Variable Composition

Fuel Cells, Volume 26, Issue 5, October 2026.
ABSTRACT This study presents a unified thermodynamic and exergy‐based assessment of autonomous fuel cell energy systems operating on biogas with varying compositions. Two alternative configurations—a solid oxide fuel cell (SOFC)‐based system and a proton exchange membrane fuel cell (PEMFC)‐based system—were evaluated using a common balance‐of‐plant ...
