Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

open access: yesChemistry – A European Journal, EarlyView.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Front Propagation Through a Perforated Wall

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Maternal and Neonatal Complications Associated with Breast Cancer Systemic Treatments—A VigiBase Disproportionality Analysis Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pregnancy‐associated breast cancer (PrBC) presents therapeutic challenges. Understanding maternal–fetal safety of systemic anticancer therapies is critical. We performed a case/non‐case disproportionality analysis using the WHO global pharmacovigilance database up to January 2024, to evaluate maternal–fetal outcomes associated with breast cancer (BC ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Enhanced Contribution of Biexciton‐Mediated Decay Kinetics in Perovskite Nanocrystals Via Sequential Ultrafast Excitation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sequential ultrafast excitation is shown to increase the relative kinetic weighting of biexciton‐mediated decay in CsPbBr3 nanocrystals without increasing the total excitation fluence. By temporally structuring excitation within the exciton lifetime, the early‐time fast decay contribution becomes more pronounced while the fitted fast decay constants ...

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Toward Comprehensive Climate Action: Assessing Mitigation Approaches Across Canadian Municipalities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Local governments are widely regarded as key leaders in the global response to climate change. Understanding if and how municipalities commit to climate mitigation is crucial for assessing their contribution to global emission‐reduction goals and identifying barriers to effective climate transitions.

A Green Scalable Method to Prepare Zr Oxide Dicarboxylate Metal–Organic Frameworks

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A greener approach for large‐scale synthesis of MIL‐140(Zr) family for cultural heritage preservation. We report the synthesis of a series of isoreticular hydrophobic microporous zirconium dicarboxylate metal–organic frameworks (MOFs), MIL‐140(Zr)s, under green ambient pressure conditions.
