Insight‐Guided Optimization of the Individual Steps in Ambient Slot‐Die‐Coated Perovskite Solar Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This graphical abstract presents an integrated workflow for optimizing perovskite thin film fabrication by tuning ink rheology, refining processing parameters, and controlling crystallization. Viscosity control and process optimization precisely regulate wet film thickness and drying time, while crystallization directed by solvent additives yields ...

A Model for Induction Motors with Non-Uniform Air-Gap [PDF]

open access: yes, 2005
Equations to calculate inductances of induction motors, considering non-uniform air-gap, are proposed. The analyzed air-gap variations are static and dynamic eccentricity and stator slots.

Electron microscopy study of CeOx–Pd/α-Al2O3 catalysts for methane dry reforming [PDF]

open access: yes, 2009
We have investigated the interaction between Pd and Ce in a 0.47 wt % CeOx–Pd 1 wt %/ -Al2O3 catalyst that is used in the reforming reaction of CH4 with CO2.

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

open access: yesAdvanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.
