Operando X‐Ray Diffraction and Total Scattering Characterization of Battery Materials: Not Just a Pretty Picture

Advanced Energy Materials, EarlyView.
This review focuses on operando studies of battery materials by X‐ray diffraction (XRD) and total X‐ray scattering (TXS). This work highlights potential pitfalls and identify best‐practices for operando studies and reviews some unusual experiments to illustrate how these methods can be applied beyond the evaluation of the early‐stage cycling mechanisms

Mechanically Activated Luminescence in Polyurethanes Incorporating Calixarene Mechanophores

Angewandte Chemie, EarlyView.
The conformational flexibility of a calix[4]arene is exploited to obtain a reversible mechanoluminophore featuring a pyrene excimer couple at the upper rim. Stretching a linear polyurethane incorporating such mechanophore results in luminescence color change from yellow–green to blue, consistent with a force‐induced conformational motion of the ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Hydrogen Production by Reforming of Methane over NiAl₂O₄/Ce_xZr_1-xO₂ Catalysts

Chemical Engineering Transactions, 2017
This work was focused on the study of the catalytic behaviour of nickel aluminate supported either on ceria or ceria-zirconia (NiAl2O4/CexZr1-xO2, x= 0.13 and 1, 14 wt.% Ni) for the steam reforming and partial oxidation of methane.

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

Catalytic pyrolysis of impregnated biomass [PDF]

, 2005
An innovative way of catalysis was tested for its potential to reduce the amount of hydrocarbons produced during pyrolysis of oak wood. The experiments were carried out in a horizontal tubular reactor fed with a controlled flowrate of Nitrogen and ...

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

Comparison in Dimethyl Ether Steam Reforming of Conventional Cu-ZnO-Al₂O₃ and Supported Pt Metal Catalysts

Chemical Engineering Transactions, 2014
The catalytic performance of platinum based catalysts supported on CeO2/Al2O3 (with different proportion of both oxides) was compared to the conventional Cu-ZnO-Al2O3 (CZA) catalyst for methanol steam reforming (MeOH-SR), which is the second stage in the

Exploring Quantum Support Vector Regression for Predicting Hydrogen Storage Capacity of Nanoporous Materials

Advanced Intelligent Discovery, EarlyView.
In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...
