Electron paramagnetic resonance study of ErSc2NC80

open access: yes, 2010
We present an electron paramagnetic resonance (EPR) study of ErSc2N@C80 fullerene in which there are two Er3+ sites corresponding to two different configurations of the ErSc2N cluster inside the C80 cage.

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

open access: yesCarbon Innovation, EarlyView.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.
