Integration of Sustainable Carbon Nanoparticles Into Inverted Hybrid Perovskite Solar Cells to Enhance Optoelectronic Performance

open access: yesGlobal Challenges, EarlyView.
Carbon nanoparticles (CNPs) synthesized from sustainable chemicals, that is, citric acid and L‐tryptophan, using a green synthesis method, are used as additives in methylammonium PbI3 (MAPI)‐based hybrid perovskite (HPSCs) solar cells. The use of CNPs improves the device's fill factor, giving power conversion efficiencies up to 10% in comparison to 8.2%

Recycling Thermoset Systems by Vitrimerization Using Solid‐State Shear Extrusion‐ A Feasibility Study

open access: yesGlobal Challenges, EarlyView.
Vitrimerization converts permanent thermoset networks into dynamic covalent ones (vitrimers) that can be reshaped and recycled. Solid‐state shear vitrimerization via extrusion (SSSE) offers a continuous, ambient‐temperature alternative to high‐energy batch ball milling: metal‐carboxylates ligands formed during SSSE serve as junctions for the ...

Imitation of location choices for rare foreign ventures: Tax‐motivated relocations of headquarters

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary Peer firms tend to imitate each other's location choices for foreign subsidiaries. We examine whether they also engage in location choice imitation when undertaking rare, high‐stakes foreign ventures in the form of tax‐motivated relocations of headquarters.
