Mechanistic Origin of Capacity Limitation in Sidorenkite‐Type Na3‐xFe(PO4)(CO3) Carbonophosphate Cathodes for Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The potential–capacity profile reveals a one‐electron limitation in sidorenkite Na3−xFe(PO4)(CO3). Structural analysis shows that Fe4+ formation induces lattice strain and suppresses electronic conductivity, blocking further Na extraction. These findings establish key design rules: preserve crystallinity, avoid Jahn–Teller–active d4 configurations, and

Role of Graphene Oxide in the Nucleation and Growth of Gold Nanoparticles Revealed by Operando Time‐Resolved Studies

open access: yesAngewandte Chemie, EarlyView.
Graphene oxide accelerates AuCl4− reduction under irradiation and directs edge‐selective nucleation and quasi‐one‐dimensional organization of gold nanoparticles at oxygen‐rich boundaries. Operando SAXS and UV–vis spectroscopy, supported by pulse radiolysis and DFT, reveal how progressive conversion of GO to rGO removes interfacial constraints, shifting

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

The Interoperability Challenge in DFT Workflows Across Implementations

open access: yesAdvanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

Dyotropic Rearrangement of Hypervalent Iodine Species: Migrative Heterofunctionalization of Quaternary Carbons

open access: yesAngewandte Chemie, EarlyView.
1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.
