Advanced Sensor Research, EarlyView.The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.

Global bifurcation and highest waves on water of finite depth [PDF]
arXiv, 2020 We consider the two-dimensional problem for steady water waves with vorticity on water of finite depth. While neglecting the effects of surface tension we construct connected families of large amplitude periodic waves approaching the limiting wave, which is either a solitary wave, the highest solitary wave, the highest Stokes wave or a Stokes wave with

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications
Advanced Intelligent Systems, EarlyView.Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Single-mode silica microsphere Raman laser tunable in the U-band and beyond
Results in Physics, 2020 We demonstrate experimentally a silica microresonator-based single-mode Raman laser tunable in the U-band and beyond. The Stokes wavelength is tuned in the 1631–1685 nm range when tuning a C-band pump laser in the 1520–1570 nm range.

Nonlinear modulational instabililty of the Stokes waves in 2d full water waves [PDF]
arXiv, 2020 The well-known Stokes waves refer to periodic traveling waves under the gravity at the free surface of a two dimensional full water wave system. In this paper, we prove that small-amplitude Stokes waves with infinite depth are nonlinearly unstable under long-wave perturbations.

Advanced Physics Research, EarlyView.The geometrical shaping of coumarin‐153 single crystals into next‐generation disc and ring resonators using Xe‐plasma FIB milling is demonstrated. Optimized beam parameters (30 kV, 100 pA/50 pA) enabled precise fabrication. This approach minimizes structural damage while ensuring high‐quality photonic traits.
