Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

Advanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Reconstructing Three‐Dimensional Optical Anisotropy with Tomographic Müller‐Polarimetric Microscopy

Advanced Science, EarlyView.
Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...

Harnessing Dynamic Electrostatic Fields for Energy Generation with Diode Cells

Advanced Science, EarlyView.
Stationary diode cells (DiCes) are fabricated to harvest energy from dynamically changing electrostatic fields by leveraging the unique current modulation properties of diodes. The DiCes can directly output DC voltage and current. Their applications range from energy harvesting and powering implanted devices to use in sensors.

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...
