Toward a Universal Czochralski Growth Model Leveraging Data‐Driven Techniques

open access: yesAdvanced Theory and Simulations, EarlyView.
This data‐driven study investigates Czochralski growth using Decision Trees, Symbolic Regression, ANN, and SHAP to assess the impact of 21 process and design parameters on crystal quality. Trained on 632 CFD simulation datasets across four crystalline materials, it demonstrates the feasibility of a universal Cz model applicable to various ...

Sobre la electrodinámica de los cuerpos en movimiento

open access: yesMemoria Investigaciones en Ingeniería, 2005
Es bien conocido que la electrodinámica de Maxwell—como se le entiende usualmente en la actualidad—aplicada a los cuerpos en movimiento, conduce a asimetrías que no parecen ser inherentes a los fenómenos.

Boosting Electrochemiluminescence of Carbon Nitrides via Molecular Capacitor‐Mediated Spatiotemporal Electron Coordination

open access: yesAdvanced Science, EarlyView.
Molecular capacitors are modified on carbon nitrides (CN) to dynamically regulate electron capture and accumulation in the defect states under different potentials. As a result, the electrochemiluminescence (ECL) efficiency increases by up to 100 times, owing to a new spatiotemporal coordination mechanism.

Unveiling Alkali‐Induced Redox Modulation: In‐Situ Spectroscopic Insights from RWGS on Alkali‐Modified ZrO2‐Supported Cu Catalysts

open access: yesAdvanced Science, EarlyView.
Revisiting the prevailing views that alkali only enhances adsorption properties and stabilizes metal particles against sintering, this study highlights the key role of Na+ in modulating Cu redox properties. Na+ added via wet impregnation (WI) hinders Cu2+ reduction but promotes oxidation and leads to Cu site loss by sintering/coverage. In contrast, the
