Innovative electrospun geopolymer/zeolite/PVA composite membranes

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Proposed scheme of gas adsorption mechanisms on electrospun geopolymer/zeolite/PVA composite membranes. Abstract Innovative electrospun poly(vinyl alcohol) (PVA)–geopolymer–zeolite 13X composite membranes were successfully fabricated and systematically characterized.

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Post‐Synthetic Bimetallic Assembly of 2D CoFe‐MOF Composite as an Electrocatalyst for the Oxygen Evolution Reaction

open access: yesCleanMat, EarlyView.
Post‐synthetic bimetallic assembly constructs a 2D CoFe‐MOF composite. DFT confirms Fe→O→Co synergy optimizes the OER pathway (ΔGmax = 1.67 eV), leading to ultralow overpotential (290 mV) and robust stability. ABSTRACT Metal‐organic frameworks (MOFs) are promising oxygen evolution reaction (OER) electrocatalysts, yet their commercial viability is ...

Detection of Particulate Matter With Lock‐In Thermography

open access: yesCleanMat, EarlyView.
Accurate quantification of black carbon is essential due to its significant impact on climate, air quality, and human health. Lock‐in thermography (LIT), as implemented by NanoLockin's instrument Calorsito, offers a sensitive, scalable, and reproducible approach for detecting black carbon on filter substrates.
