Mid-infrared Extinction toward the Galactic Center
The Astrophysical JournalWe determine the mid-infrared (MIR, ∼5–22 μ m) extinction toward the Galactic center using MIRI/Medium-Resolution Spectrometer (MRS) integral field unit observations of the central 3″ × 3″ region (near 5 μ m) to 7″ × 7″ region (near 22 μ m).

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2
Advanced Optical Materials, EarlyView.Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.

High energy emission from the Galactic Center: Theory and observations
EPJ Web of Conferences, 2015 Galactic Centre is a bright γ-ray source with the GeV-TeV band spectrum composed of two distinct components in the 1–10 GeV and 1–10 TeV energy ranges. The nature of the two components is not clearly understood.

Journal of Physics: Conference Series, 2012 We present for the first time, an infrared data-cube of the central parsec of our Galaxy in the 2.8 to 4.2 micron range. This spectral band (the L-band) harbors important signatures of the interstellar and circumstellar medium, since the water ice absorption feature at 3 micron traces the dense medium and the hydrocarbon absorption at 3.4 micron is ...

Advanced Optical Materials, EarlyView.Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Advanced Optical Materials, EarlyView.A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
