Advancing Bipolar Electrochemistry for Targeted Deposition of Biocompatible Polymers in Electrolyte‐Free Solutions via Finite Element Modeling

open access: yesChemElectroChem, Volume 12, Issue 6, March 15, 2025.
Modeling and experimental data for the synthesis and deposition of conducting polymers in high‐resistance solutions enabled by bipolar electrochemistry indicate the reaction control via homogenous rather than heterogeneous electron transfer conventionally postulated for bipolar electrochemical systems.

Tailoring Photophysical Processes of Er3+‐Doped Gd3Ga5O12 Garnets for Enhanced Photoluminescence via Al3+ Ion Preference Substitution

open access: yesCarbon Energy, EarlyView.
The preferential substitution of Al3+ ion at octahedral‐coordinated GaI sites of Er3+‐co‐doped Gd3Ga5O12 garnets achieved a PLQY enhancement of the down‐shifting luminescence from 35.1% to 68.5%. Al3+ ion also influences electron relaxation during up‐conversion luminescence, resulting in a color shift from red to yellow to green.

Kinetically arrested SERS‐Active aggregates for biosensing

open access: yesChemistry – A European Journal, Accepted Article.
There is a demand for biosensors capable of long‐term, non‐invasive monitoring of low analyte concentrations in various biofluids for diagnostics, personalized healthcare, and disease monitoring. Biofluids present challenges to biosensor sensing and stability on account of their complex composition and dynamic nature.

Antibacterial and antiviral activity of a highly efficient electrospun r‐PET nanofiber

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Since the COVID‐19 pandemic, the emergence of clean air has increased interest in developing antimicrobial air filters, targeting sterilization and public health concerns. Nanofibers are a promising approach due to their high efficiency in air filtration, while nanoparticles adhered to the fibre surfaces can improve safety due to the biocidal ...

Correlative Characterizations Reveal the Structure‐Bonding‐Property Relationship at a Local Scale

open access: yesChemistry–Methods, EarlyView.
Grain boundaries (GBs) modify the local microstructures, chemical bonding, and carrier transport of polycrystalline materials, influencing their overall mechanical and functional properties. We developed a correlative characterization method by combining several advanced ex‐situ and in‐situ techniques to reveal the relationship between structure ...

Machine Learning–Driven Screening of High‐Activity Antitumor Nanozymes Using an Ensemble Enzymatic Oracle System

open access: yesCancer Nexus, EarlyView.
ABSTRACT Nanozymes, by mimicking the catalytic sites of natural enzymes, have emerged as effective substitutes for traditional natural enzymes. However, the relationship between the physicochemical properties and activity of nanozymes is complex and nonlinear.

Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

open access: yesChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated

Tackling Environmental Impact: A New Support Tool for Sustainable Healthcare Waste Management

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study proposes a novel framework integrating Environmental Risk Assessment (ERA) and Material Flow Analysis (MFA) within the Deming Cycle framework to address this gap. While valuable tools, ERA and MFA offer limited perspectives on environmental impact when used alone.
