Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

open access: yesAdvanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.

Reducing Personalization Time and Energy Cost While Walking Outdoors with a Portable Exosuit

open access: yesAdvanced Robotics Research, EarlyView.
Rapid Real‐World Optimization! An AF‐based human‐in‐the‐loop optimization strategy rapidly personalizes a portable hip extension exosuit for incline walking. Real‐time Bayesian optimization of assistive force significantly reduces metabolic energy—up to 16.2%—while converging in just 3 min 24 s.

Colorimetric Sensors with Enhanced Sensitivity and Angle‐independence

open access: yesAdvanced Sensor Research, EarlyView.
This review discusses various approaches, including the use of photonic crystals and colloidal photonic crystals as structural materials, and surface plasmon resonance as a light manipulation mechanism, to improve the sensitivity of colorimetric sensors.

Upregulation of miR-489-3p and miR-630 inhibits oxaliplatin uptake in renal cell carcinoma by targeting OCT2

open access: yesActa Pharmaceutica Sinica B, 2019
Renal cell carcinoma (RCC) is one of the most common malignant tumors affecting the urogenital system, accounting for 90% of renal malignancies. Traditional chemotherapy options are often the front-line choice of regimen in the treatment of patients with

Sustainable 3D‐Printed Platforms with Durable Photocatalytic Coatings for Efficient Water Treatment

open access: yesAdvanced Sustainable Systems, EarlyView.
This work presents a sustainable 3D‐printed scaffold with a bioinspired, wear‐resistant surface for photocatalyst coatings. The nano‐enabled scaffolds demonstrate exceptional stability, maintaining performance after 30 cycles of chemical regeneration and UV irradiation, while achieving a removal efficiency of 93%.

Optically Switchable Fluorescence Enhancement at Critical Interparticle Distances

open access: yesAdvanced Theory and Simulations, EarlyView.
In this work, we present the results of a complete FDTD (Finite Difference Time Domain) model specifically tailored for the precise determination of critical interparticle distances yielding observable fluorescence enhancement. We further report an optical switch applied on a metal nanoparticle to actively control the radiative decay rate of a closely ...
