As the rise of nonfullerene acceptors (NFA) has allowed lab‐scale organic solar cells (OSC) to reach 20% efficiency, translating these devices into roll‐to‐roll compatible fabrication still poses many challenges for researchers. Among these are the use of green solvent solubility for large‐scale manufacture, roll‐to‐roll compatible fabrication, and, not least, information on charge carrier dynamics in each upscaling step, to further understand the gap in performance. In this work, the reproducibility of champion devices using slot‐die coating with 14% power conversion efficiency (PCE) is demonstrated, under the condition that the optimal thickness is maintained. It is further shown that for the donor:acceptor (D:A) blend PM6:Y12, the processing solvent has a more significant impact on charge carrier dynamics compared to the deposition technique. It is found that the devices processed with o‐xylene feature a 40% decrease in the bimolecular recombination coefficient compared to those processed with CB, as well as a 70% increase in effective mobility. Finally, it is highlighted that blade‐coating yields devices with similar carrier dynamics to slot‐die coating, making it the optimal choice for lab‐scale optimization with no significant loss in translation toward up‐scale.

Light‐trapping nanostructures have for decades been researched as a route to enhance the performance of organic solar cells (OSCs). Whereas the power conversion efficiencies (PCEs) of OSCs have reached above 18 %, industrially compatible devices made by scalable processing in air, using only nontoxic solvents and materials, have shown significantly lower performance values. Although light‐trapping nanostructures may improve this, the methods for integrating the nanostructures are typically not compatible with industrial scale up. In this work, scalable, industrially compatible, nonfullerene‐based OSCs are developed with integrated light‐trapping nanostructures at the back electrodes in the devices. The OSCs are made by using scalable roll‐to‐roll (R2R) and sheet‐to‐sheet (S2S) processes and the nanostructures are made by using roll‐to‐plate (R2P) nanoimprint lithography. A fully scalable solution is thereby developed for industrially compatible nanostructured OSCs. The nanostructured devices show enhancements in PCE up to 25 % compared to reference cells, owing to an enhancement in the short‐circuit current density (15 %) by enhanced absorption, and improved charge carrier extraction leading to an enhancement in the fill factor (7 %). Optical modeling is utilized to verify the optical effect of the nanostructures. The best devices attain a PCE of 6.5 %, which is the highest reported efficiency for air‐processed slot‐die coated ITO‐free flexible PBDB‐T : ITIC devices, here using nontoxic solvents.

In clinical practice, tetracycline antimicrobial agents often lead to adverse events with drug fever and leukemoid reaction (LR) being rare occurrences. Here, we present a case of tigecycline-induced LR in a burn patient, which we believe is the first reported case of tigecycline-induced drug fever and LR globally in a burn patient and second overall., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Iatrogenic vascular injuries are rare but potentially serious complications that can occur during orthopedic procedures involving the proximal humerus. We present a case report of a patient who sustained a brachial artery injury during a long Proximal Humeral Interlocking System (PHILOS) plating procedure for a proximal humeral fracture. A 62-year-old female patient with a left humerus proximal 1/3 shaft fracture underwent open reduction and internal fixation with a long PHILOS plate. During the procedure, difficulty was encountered in achieving adequate plate positioning due to osteoporotic bone and fracture comminution. Upon insertion of a distal second last screw, brisk brachial artery bleeding was encountered. Immediate hemostasis measures were taken, and a plastic surgeon was consulted. The brachial artery injury was identified and repaired with a cephalic vein graft harvested and flushed. Postoperatively, the patient developed median nerve neuropraxia. This case highlights the risk of iatrogenic brachial artery injury during left humerus proximal 1/3 shaft fracture fixation, especially in cases with technical challenges due to osteoporotic bone or comminution. Prompt recognition, involvement of vascular surgery, and appropriate management are crucial in mitigating potential devastating consequences. Associated neurological complications, such as nerve injuries, can also occur and should be monitored. Meticulous surgical technique, anatomical awareness, and vigilant monitoring are essential to minimize the risk of vascular and neurological complications during these procedures. Iatrogenic brachial artery injury is a rare but potentially serious complication of humerus proximal 1/3 shaft fracture. Early recognition, multidisciplinary involvement, and appropriate management strategies are crucial in optimizing patient outcomes and preventing long-term morbidity., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.
