Perimeter‐intensified inverse Zr‐Co oxygen carrier for biomass chemical‐looping gasification with high CO selectivity

AIChE Journal, EarlyView.
Abstract Chemical‐looping gasification (CLG) offers a promising route for renewable biomass valorization, yet conventional oxygen carrier regeneration with O₂/H₂O is energy‐intensive and often produces low‐quality syngas. Here, we develop an inverse ZrO2/Co3O4 oxygen carrier that enables selective biochar oxidation and efficient lattice‐oxygen transfer

Facet‐Dependent Water Inhibition of Alkanol Dehydration on TiO2 via Distinct Water–Alkanol Complexes

Angewandte Chemie, EarlyView.
Water inhibits alkanol dehydration on TiO2 through facet‐dependent manners via distinct IPA‐water complexes. On TiO2(001), water forms a strongly hydrogen‐bonded isopropoxide–H2O complex that readily dominates the surface and substantially elevates the activation barrier, whereas on TiO2(101), water weakly hydrogen‐bonds to molecular IPA, resulting in ...

An Autonomous Large Language Model‐Agent Framework for Transparent and Local Time Series Forecasting

Advanced Intelligent Discovery, EarlyView.
Architecture of the proposed large language model (LLM)‐based agent framework for autonomous time series forecasting in thermal power generation systems. The framework operates through a vertical pipeline initiated by natural language queries from users, which are processed by the LLM Agent Core powered by Llama.cpp and a ReAct loop with persistent ...

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

Angewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Talk to Your Data: An Agentic Artificial Intelligence‐Driven Decision‐Support Framework for Prosumer Energy Optimization and Recommendations

Advanced Intelligent Systems, EarlyView.
An agentic AI‐driven decision‐support framework for prosumers is proposed, integrating PV generation, load profiling, and multihorizon optimization within a four‐agent architecture. The approach significantly reduces grid dependence, enhances self‐sufficiency and prevents system oversizing.

Ketazine‐Linked Covalent Organic Framework for Metal‐Free Electrocatalytic Nitrate‐to‐Ammonia Conversion

Angewandte Chemie, EarlyView.
A metal‐free fluorinated ketazine‐linked COF is introduced as an efficient electrocatalyst for nitrate reduction to ammonia under neutral conditions. Fluorine substitution enhances π–π stacking and crystallinity, enabling a Faradaic efficiency of 59.9% and an NH3 yield rate of 1639.9 µmol h−1 mgCOF−1 at −0.9 V versus RHE. This establishes an unexplored
