Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

A Co‐Deposition Approach for Self‐Assembled Molecules and Perovskites Achieving > 20% Efficiency in Wide‐Bandgap Perovskite Solar Cells

EcoEnergy, EarlyView.
Developing the π‐conjugation extended carbazole self‐assembled molecule, written as XS22, for efficient co‐deposited wide‐bandgap perovskite solar cells. ABSTRACT Co‐deposited strategy of self‐assembled molecule (SAM) and perovskite could simplify the fabrication process as well as achieving the high‐performance solar cells.

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Synthesis of α‐C‐Glycoside Conjugates Promoted by 4CzIPN‐Based Porous Organic Polymers Through Giese‐Like Reaction of Glycosyl Bromides in Batch and Continuous Flow

European Journal of Organic Chemistry, EarlyView.
Visible light and a 4CzIPN‐based porous organic polymer (4CzIPN‐POP) enable Giese‐like coupling of glycosyl bromides with electron‐poor alkenes to access α‐C‐glycoside conjugates. The study shows how heterogeneous thermally activated delayed fluorescence photocatalysis can be combined with continuous flow to overcome light penetration limits and ...
