Harnessing γ‐Valerolactone: Green and Low‐Toxic Solvent for Enhanced Dye‐Sensitized Solar Cells Performance Under Indoor Lighting

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This research explores the use of γ‐valerolactone (γ‐VL), a sustainable and low‐toxic solvent, as an alternative for dye‐sensitized solar cell electrolytes. Results indicate that while γ‐VL is less suitable for outdoor applications, it significantly outperforms traditional solvents like acetonitrile and 3‐methoxypropionitrile under indoor lighting ...

Organic‐Inorganic Photosynthetic Interfaces Built on Intertwined WO3 Nanosheets for Enhanced HBr/H2O Photoanodic Oxidations

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Three‐dimensional WO3 nanosheets (3D‐NS) with exposed {001} facets are grown in situ, forming a highly interconnected 3D architecture, which is sensitized with a polymeric perylene bisimide layer and test for HBr photooxidation. The self‐assembly of a quantasome architecture—based on perylene bisimide dyes, templated around a tetra‐ruthenated ...

A Machine Learning Perspective on the Brønsted–Evans–Polanyi Relation in Water‐Gas Shift Catalysis on MXenes

open access: yesAdvanced Intelligent Discovery, EarlyView.
Machine learning predicts activation energies for key steps in the water‐gas shift reaction on 92 MXenes. Random Forest is identified as the most accurate model. Reaction energy and reactant LogP emerge as key descriptors. The approach provides a predictive framework for catalyst design, grounded in density functional theory data and validated through ...

Analysis of the Navigation of Magnetic Microrobots through Cerebral Bifurcations for Targeted Drug Delivery

open access: yesAdvanced Intelligent Systems, EarlyView.
The motion of magnetic microrobots through cerebral bifurcations depends on various parameters such as the microrobots size, the blood velocity, and the imposed magnetic field gradients, among others. This work presents an in‐depth analysis of the effects of these parameters and equations predicting the required magnetic gradients based on the ...
