Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, Volume 29, Issue 13, 1 May 2026.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Navigating uncertainty in life cycle assessment‐based approaches to biodiversity footprinting

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1387-1404, May 2026.
Abstract The use of life cycle assessment (LCA) methods is rapidly expanding as a means of estimating the biodiversity impacts of organisations across complex value chains. However, these methods have limitations and substantial uncertainties, which are rarely communicated in the results of LCAs.

ANALYSIS OF EXHAUST GAS EMISSION IN THE MARINE TWO-STROKE SLOW-SPEED DIESEL ENGINE

Brodogradnja, 2016
This paper explores the problem of exhaust emissions of the marine two-stroke slow-speed diesel engines. After establishing marine diesel engine regulations and defining the parameters influencing exhaust emissions, the simulation model of the marine two-

What Is the Best Use of Biomass? A Harmonized LCA‐TEA Framework Quantifying Economic and Environmental Metrics for Bioenergy Pathways

GCB Bioenergy, Volume 18, Issue 5, May 2026.
A harmonized LCA and TEA framework evaluates 19 bioenergy pathways, quantifying carbon intensity (CI), minimum fuel selling price (MFSP), and marginal abatement cost (MAC). CCS reduces CI to net‐negative values and lowers MAC by up to 64%, with bioelectricity achieving the lowest MAC and liquid biofuels critical for hard‐to‐abate sectors.
