Advanced Materials Interfaces, EarlyView.Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Terahertz quantum cascade laser with non-resonant extraction
AIP Advances, 2019 In order to improve the maximum operating temperature of THz quantum cascade lasers (QCLs) we propose to modify the three well resonant phonon design by increasing the energy of the separation between the bottom transition levels and the ground states ...

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, EarlyView.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
Advanced Optical Materials, EarlyView.An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...
