Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Ligand‐Intercalated MOFs Enable Reaction‐Pathway Engineering in Biomass Electrooxidation via Steric and π‐Electronic Microenvironment Control

open access: yesAngewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Through ligand length and π‐electron density modulation, metal–organic frameworks (MOFs) improve mass transport and hydrogen atom transfer (HAT), thus improving biomass electrooxidation. ABSTRACT Controlling reaction pathways in electrocatalytic biomass upgrading remains challenging because mass transport, substrate adsorption, and elementary kinetics ...

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

open access: yesMaterials and Corrosion, EarlyView.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.

Antiferromagnetic Chains in a Monolayer of Molecular Qubits Assembled on Graphene

open access: yesSmall, EarlyView.
This work explores the deposition onto graphene of a dithiazole‐based molecular qubit, [Cu(dttt)2], (dttt− = 1,3,2‐dithiazole‐4‐thione‐5‐thiolate), under ultra‐high vacuum conditions. Analytical techniques, including STM, XPS, and X‐ray absorption, reveal the molecular arrangement and magnetic interactions, emphasizing the role of vdW interactions in ...

The Resistance–Amplitude–Frequency Effect of In–Liquid Quartz Crystal Microbalance

open access: yesSensors, 2017
Due to the influence of liquid load, the equivalent resistance of in-liquid quartz crystal microbalance (QCM) increases sharply, and the quality factor and resonant frequency decreases.

Advances in cholesterol and lipoproteins detection for healthcare: A review

open access: yesVIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most
