Photolithographic Patterning of Colloidal Quantum Dots Enabled by Plasma‐Induced Ligand Polymerization

Advanced Materials Technologies, EarlyView.
Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...

Rethinking the Secrecy Outage Formulation: A Secure Transmission Design Perspective

, 2011
This letter studies information-theoretic security without knowing the eavesdropper's channel fading state. We present an alternative secrecy outage formulation to measure the probability that message transmissions fail to achieve perfect secrecy.

MEOX1 Coordinates Autocrine‐Paracrine Programs via SPHK1/S1P to Promote Lymph Node Metastasis in Ovarian Cancer

Advanced Science, EarlyView.
In ovarian cancer, MEOX1 activates the SPHK1/S1P pathway to promote both tumor progression and tumor–stroma crosstalk. MEOX1‐dependent signaling drives CAF activation, enhances VEGF‐C expression, and stimulates lymphangiogenesis, ultimately facilitating lymph node metastasis.
