Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...

Liquid–liquid equilibrium studies of n‐butane–bitumen system with application to solvent‐aided in situ bitumen recovery

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Solvent‐assisted recovery methods have gained attention as an alternative to conventional thermal methods which have significant environmental drawbacks and high greenhouse gas emissions. Solvent‐assisted recovery methods can lead to various phase equilibria, such as vapour–liquid equilibrium (VLE) and liquid–liquid equilibrium (LLE), under ...

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

The Role of High‐Gradient Diffusion Nuclear Magnetic Resonance in Exploring Peculiarity of Water in Ionic Liquids Doped with Alkali Metals

open access: yesChemistry–Methods, EarlyView.
Applying high gradients during diffusion nuclear magnetic resonance experiments allows for the determination of isolated microenvironments in ternary solutions composed of an imidazolium‐based ionic liquid, water and alkali metal halide. Two separate water populations are detected, forming either the isolated solvent network or the first solvation ...
