Enhanced Contribution of Biexciton‐Mediated Decay Kinetics in Perovskite Nanocrystals Via Sequential Ultrafast Excitation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sequential ultrafast excitation is shown to increase the relative kinetic weighting of biexciton‐mediated decay in CsPbBr3 nanocrystals without increasing the total excitation fluence. By temporally structuring excitation within the exciton lifetime, the early‐time fast decay contribution becomes more pronounced while the fitted fast decay constants ...

Enhancing g‐C3N4 Photocatalytic Activity: K‐Doping and CuO Heterojunction for Selective CO2 Conversion to CH4

open access: yesElectron, EarlyView.
The CuO/K‐g‐C3N4 heterostructure photocatalyst achieves selective CO2 reduction to CH4 (93.03% selectivity) under visible‐light irradiation. K‐doping enhances crystallinity, whereas CuO forms a p‐n heterojunction to promote charge separation and electron transfer.

Effectiveness and safety of implantable vagus nerve stimulation in people with primary generalized tonic–clonic seizures

open access: yesEpilepsia Open, EarlyView.
The impact of prompt diagnosis and treatment, and early predictors of outcome severity in this cohort. Abstract Objective Most therapies for drug‐resistant epilepsy (DRE) focus on focal‐onset seizures, the most common seizure types. Studying primary generalized tonic–clonic seizures (PGTCS) is more challenging due to diagnostic and recruitment ...

Renewable Energies in Kazakhstan: Current Status, Potential, Challenges, and Opportunities

open access: yesEnergy Science &Engineering, EarlyView.
Kazakhstan has strong renewable energy potential, with wind as the leading resource and solar and other sources offering additional opportunities. Key challenges include limited infrastructure, investment needs, and grid‐related technical issues. Despite these barriers, renewables can boost economic diversification, enhance energy security, create jobs,

Inter‐Material Transfer Learning for Accelerated Nanofluid Heat Transfer Prediction: A Machine Learning Approach for Energy Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study presents an inter‐material transfer learning framework for nanofluid heat transfer prediction in energy systems. By leveraging knowledge from Al2O3‐water data, the model accurately predicts hybrid Al2O3‐TiO2 nanofluid performance with only 20 simulations, achieving R2 = 0.985 and reducing computational requirements by 78.
