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,

Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

The research progress in polyethylene oxide polymer electrolytes

open access: yesFlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Synthesis of hydrazone derivatives of quinoline / Amira Safwani Abd Rahim [PDF]

open access: yes, 2013
Twenty five new series of hydrazones derivatives of quinoline were synthesized starting from quinoline-6-carbohydrazide. Firstly, methyl quinoline-6-carboxylate was reacted with hydrazine hydrate to form quinoline-o-carbohydrazide as a starting material.

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.
