Enhanced Performance of Optoelectronic Devices Using Metal Chalcogenide Complex Ligands‐Capped InAs/ZnSe Quantum Dots as Electron Transport Layers

Advanced Energy Materials, EarlyView.
Thin‐shell InAs/ZnSe quantum dots functionalized with metal chalcogenide ligands were employed as electron transport layers in organic optoelectronic devices, yielding optimized conduction band alignment and film morphology. Consequently, the devices achieved enhanced charge transport, a detectivity of ∼1013 Jones, and a power conversion efficiency of ...

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

BJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Lymph Node Metastasis Pattern and Influencing Factors in Esophageal Squamous Cell Carcinoma

AGING MEDICINE, EarlyView.
Among 388 patients with esophageal squamous cell carcinoma who underwent curative resection, 144 (37.1%) developed lymph node metastasis. Upper thoracic tumors mainly involved upper mediastinal and upper right paratracheal nodes, whereas lower thoracic tumors more often involved paracardial and abdominal nodes.
