The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

open access: yesChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents

open access: yesChemistry – A European Journal, EarlyView.
Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

Non‐State Regulators? Civil Society as Extension of the State in a Context of a Regularization Scheme for Undocumented Migrants

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT “Opération Papyrus” was implemented in the Swiss Canton of Geneva between 2017 and 2018 with the aim of granting residence permits to undocumented migrants who met pre‐established criteria. This program serves as an exemplary case of involving nongovernmental actors to facilitate what were originally state‐controlled procedures.

Cardiorespiratory cross‐frequency coupling biomarker for sudden unexpected death in epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Sudden unexpected death in epilepsy (SUDEP) often follows generalized tonic–clonic seizures during sleep, likely resulting from impaired brainstem cardiorespiratory function. We used ictal electrocardiogram (ECG)‐based cross‐frequency phase–amplitude coupling (PAC) to detect cardiorespiratory disruptions, comparing SUDEP to non‐SUDEP

Synchrotron‐generated microbeams as a radiosurgical alternative for drug‐resistant epilepsies: Proof of concept in a mouse model of mesiotemporal lobe epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective One‐third of patients with epilepsy, particularly those with mesial temporal lobe epilepsy (MTLE), remain resistant to medication. Resective surgery, the gold standard, is highly invasive and carries significant risks. Here, using a mouse model, we explored the potential of microbeam radiation therapy (MRT), a new technique based on ...

Navigating the Digital World: Pre‐Service Teachers' Processes and Perspectives on Evaluating Online Information

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT This descriptive case study examined how undergraduate pre‐service teachers (PSTs) enrolled in a digital literacies course evaluated online information as part of a module digital project. PSTs were tasked with assessing peer‐selected online texts using multiple strategies in an unrestricted web environment.
