The cathode interlayer (CIL) plays a crucial role in organic solar cells (OSCs), which can establish an Ohmic contact between the active layer and electrode, lower electron extraction barriers, minimize charge carrier recombination. CIL modification is useful strategy for improving performance of OSCs. Herein, inexpensive water–alcohol‐soluble material known as L‐Arginine (L‐Arg) introduced modifier PFN‐Br CIL, leading to successful optimization quality. Following L‐Arg modification, work...

This work synthesized polyethyleneimine and chitosan modified winter melon-derived biochar (PEI-CTS@WBC) using chemical crosslinking method for uranium(VI) removal. The factors influencing adsorption by PEI-CTS@WBC, including pH, adsorbent dosage, time, temperature, initial U(VI) concentration were explored. material's performance was characterized, the underlying mechanism of removal analyzed various techniques. results demonstrated that PEI-CTS@WBC effectively removed U(VI), achieving a...

Unsteady cloud cavitation significantly impairs the performance of marine systems. Active flow control method has shown promise in effectively reducing cavitation, yet its specific mechanisms action require elucidation. This study investigates continuous water injection on a NACA66 (MOD) hydrofoil as an active against unsteady cavitation. Results show notable reductions volume: 52.57% at number 0.83 and 86.24% 1.29. Employing Lagrangian approach, tracks ideal particles to explore jet's...

Tuning the three-dimensional morphology in active layer is an effective method to improve performance of bulk heterojunction organic solar cells (OSCs). In this work, acceptor–donor–acceptor structured small molecule ST10-CN-1 was synthesized and employed as guest donor fabricate ternary OSCs based on a PBDB-T:IT-M host binary system. The incorporation could broaden layer's absorption range light thereby leading promotional short-circuit current. Moreover, adding appropriate amount...
