Cobalt Single‐Atom Sites Engineered in Poly(Heptazine Imide) Photocathodes as Benchmark for Alkaline Hydrogen Evolution: A Comparative Transition Metal Study

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt single‐atoms in poly(heptazine imide) photocathodes maximize active‐site availability and outperform Fe, Cu, and Na in alkaline hydrogen evolution. Atomic precision (not bulk loading) proves predominance, establishing a design principle for the next generation of solar fuel devices.

Pragmatic screening for autoimmune‐associated epilepsy in drug‐resistant epilepsy of unknown etiology in resource‐limited settings: A hypothesis‐generating study

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective To evaluate the feasibility of investigating autoimmune etiology in adults with drug‐resistant epilepsy (DRE) of unknown origin in resource‐limited settings and to develop a pragmatic, hypothesis‐generating screening approach to guide autoantibody testing. Methods A prospective observational study including adults with DRE of unknown

DFT and Machine Learning Analysis of Eco‐Friendly Formamidinium Tin Iodide Perovskite Solar Cells: Optimizing Charge Transport Layers Through SCAPS‐1D Simulations

open access: yesEnergy Science &Engineering, EarlyView.
Machine learning using Random Forest, GB, XGBoost, and LightGBM regression algorithms: SHAP plot for PCE. ABSTRACT Tin‐based solar cells are the eco‐friendly alternative to the toxic lead‐based cells that are currently in use. In this context, Formamidinium Tin Iodide (FASnI3) emerges as a promising candidate due to its superior performance, exhibiting

Numerical Design and Performance Optimization of Lead‐Free CsSnGeI3 Perovskite Solar Cells Using Cu2O Hole Transport Layer via SCAPS‐1D

open access: yesEnergy Science &Engineering, EarlyView.
The optimal structure of the device FTO/ZnS/CsSnGeI3/Cu2O/Au consists of a CsSnGeI3 absorber layer and ZnS as the buffer layer, FTO as the electron transport layer, and Cu2O as the hole transport layer. For the back contact, gold is utilized. According to the current density–voltage curve, efficiency increases with thickness concurrently.
