Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Modular π‐Extended IF‐TTF Systems: Tuning Redox and Optical Properties in Donor–Acceptor and Donor–Donor Frameworks

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Donor–acceptor and donor–donor systems incorporating an indeno[1,2‐b]fluorene‐extended tetrathiafulvalene (IF‐TTF) donor motif were prepared by Suzuki coupling reactions. The compounds were studied for their optical and redox properties. The compounds showed multiredox behavior with several accessible redox states. A series of π‐extended donor–acceptor

Chiral HPLC Separation of Phosphonothrixin and Phosphonate Derivatives and Electronic Circular Dichroism Characterization of the Isolated Enantiomers

open access: yesELECTROPHORESIS, EarlyView.
Natural compound phosphonothrixin's herbicidal activity resides exclusively in its (S)‐enantiomer, yet existing enantioselective syntheses are cumbersome, and direct chiral LC separation is hampered by the compound's high polarity, lack of aromatic groups, and metal chelation–induced peak tailing.
