Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.

Effect of particle size of Martian dust on the degradation of photovoltaic cell performance [PDF]

open access: yes
Glass coverglass and SiO2 covered and uncovered silicon photovoltaic (PV) cells were subjected to conditions simulating a Mars dust storm, using the Martian Surface Wind Tunnel, to assess the effect of particle size on the performance of PV cells in the ...

A Facile Protocol for C(sp2)–C(sp3) Bond Formation Reactions Toward Functionalized E3 Ligase Ligands

open access: yesChemMedChem, EarlyView.
A robust C(sp2)–C(sp3) decarboxylative coupling strategy enables access to new CRBN ligands and degraders with improved physicochemical properties. This synthetic approach is expanding the chemical space beyond C(sp2)–N linkages, fine‐tuning proteolysis‐targeting chimera activities and unlocking previously inaccessible degrader chemotypes.

Green Synthesis of SnO2/Carbon Composite Anode for Low‐Temperature Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A green synthesis strategy is used to fabricate SnO2 nanoparticles with banana peel extract and convert the leftover biomass into carbon for composite anode materials. The resulting SnO2/hard carbon (7:3) exhibits high‐reversible capacity and excellent cycling stability at subzero temperatures, offering a scalable, eco‐friendly solution for next ...
