Dissecting Binary and Ternary Iminoboronate Assemblies: A Calorimetric Study of Thermodynamics, Kinetics, and Allosteric Effects

Abstract Dynamic covalent assemblies derived from ortho-boronoaldehydes, including iminoboronates and boronate esters, are key structural motifs in adaptive materials, chemical sensors, and reversible bioconjugation strategies. Herein, we report a label-free assay based on isothe...

An ‘Empty’ [Fe 16 ] Cage and its Transformation into [Fe 17 ] and [Fe 30 ]

ABSTRACT Polymetallic clusters of Fe III constructed without organic bridging ligands are an emerging class of molecules with structures akin to iron oxide minerals, possessing large spin ground states and/or displaying spin frustration effects. All previous examples, [Fe 8 ], [F...

Evaluating Multimodal Emotion Recognition in Proactive Conversational Agents: A User Study

ABSTRACT This article presents a multimodal emotion recognition module integrated into a proactive Socially Interactive Agent (SIA) powered by generative artificial intelligence. The system evaluates real‐time affective states through two distinct channels: a computer vision‐base...

Mapping tourism potential: a GIS-based analytical model applied to Aragón, Spain

This poster presents a GIS-based analytical model for assessing tourism potential in Aragón, Spain. The framework integrates three dimensions: heritage attractiveness, tourism infrastructure and services, and accessibility to potential demand markets. Using the Eurostat 1 km² pop...

A detailed processing route and electrochemical validation of fuel-electrode supported planar solid oxide cells toward scalable manufacturing

Planar fuel electrode supported 5 cm × 5 cm solid oxide cells (SOCs) were manufactured by conventional methods such as tape-casting, lamination and screen printing. The chosen materials were a Ni–8% mol Y 2 O 3 -stabilized ZrO 2 (Ni-YSZ) cermet as fuel electrode, YSZ as electroly...

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

ABSTRACT Here, we demonstrate that sub‐stoichiometric amounts of alkali cations (Na + and K + ) critically govern defect formation during the synthesis of Silicalite‐1 (MFI), enabling precise control over framework integrity and surface properties after calcination. Combining sys...

Citrate-mediated structure and enthalpy-entropy trade-off in Ni-CeO2 catalysts for low-temperature CO2 methanation

Catalytic activity in heterogeneous reactions is often interpreted in terms of activation enthalpy, although reaction rates are governed by the activation free energy, which includes both enthalpic (Δ H ‡ ) and entropic (Δ S ‡ ) contributions. This simplification is particularly...
