Nanostructured Surfaces and Detection Instrumentation for Photonic Crystal Enhanced Fluorescence

Sensors, 2013
Photonic crystal (PC) surfaces have been demonstrated as a compelling platform for improving the sensitivity of surface-based fluorescent assays used in disease diagnostics and life science research. PCs can be engineered to support optical resonances at

Sustained and Enhanced Nucleate Boiling Using Hierarchical Architectures at Large Superheats

Exploration, EarlyView.
Sustained nucleate boiling and Leidenfrost delay are critical for thermal and energy industries. Leveraging vapor buffer and reducing water‐hammer pressure, this study realizes the enhancement of nucleate boiling and postponement of Leidenfrost by rationally designing and developing hierarchical nano–micro structured surfaces. Besides, AI technology is

Enhancing the efficiency of high-order harmonics with two-color non-collinear wave mixing in silica

Nature Communications
The emission of high-order harmonics from solids under intense laser-pulse irradiation is revolutionizing our understanding of strong-field solid-light interactions, while simultaneously opening avenues towards novel, all-solid, coherent, short ...

Uncovering Hidden Resonances in Non‐Hermitian Systems with Scattering Thresholds

Laser &Photonics Reviews, EarlyView.
The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non‐Hermitian systems are referred to as scattering thresholds. Close to these branch points, resonances from different Riemann sheets can tremendously impact the optical response.

Synthesis and Characterization of Methacrylamide‐Based Block Random Copolymers via Amine Functionalization of Polystyrene‐Block‐Poly(Pentafluorophenyl Methacrylate) Toward Enhanced Amenability to Manufacturing Criteria in Nanolithography

Macromolecular Chemistry and Physics, EarlyView.
Polystyrene‐block‐poly(pentafluorophenyl methacrylate) (PS‐b‐PPFMA) is functionalized with primary amines to develop A‐block‐(B‐random‐C) block copolymers (BCPs). These BCPs exhibit high thermal stability and circumvent sources of undesired side reactions upon heating on account of its methacrylamide functionality.

Optimizing the Performance of Printed Indium Oxide Thin‐Film Transistors through Gallium Incorporation

physica status solidi (a), EarlyView.
This study reports gallium incorporation into indium oxide nanoparticle inks for low‐temperature fabrication of electrolyte‐gated transistors. Electrical analyses reveal threshold voltage modulation and suppressed leakage currents, due to the incorporation of gallium.

Substrate‐Versatile and Stress‐Free Tellurization of PtTe2 Films

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step (platinum deposition followed by tellurization) scalable process that can be easily combined with lithographic techniques is developed for the growth of PtTe2 films. By optimizing a slower tellurization thermal ramp, stress‐free PtTe2 growth both on silicon and dielectric substrates is achieved, proving substrate versatility.
