High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures
Advanced Functional Materials, EarlyView.Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...

Deep learning-assisted reconstruction of Raman speckle images transmitted through biological tissues
Journal of Innovative Optical Health SciencesPrecise delineation of tumor tissues during surgery is hindered by the strong scattering and absorption of photons in biological tissues, which obscure molecular imaging signals and hinder intraoperative navigation.

Spectral interferometric coherent Raman imaging
Optics Express, 2005 We propose a low-background and sensitive coherent Raman imaging technique that uses selective excitation of Raman levels with chirped pulses from a single femtosecond laser. The proposed scheme uses spectral interferometric detection to obtain the real and imaginary parts of chi(3) simultaneously.

Advanced Functional Materials, EarlyView.2,2,2‐trifluoroethanamide‐mediated coordination regulation reconstructs the local Li+ environment in PVDF‐HFP polymer electrolytes by weakening residual DMF‐dominated coordination and promoting TFSI−‐involved anion‐rich solvation. This strategy facilitates Li+ migration and interfacial desolvation, promotes the formation of a thin inorganic‐rich SEI ...

Raman Hyperspectral Imaging for Detection of Watermelon Seeds Infected with Acidovorax citrulli
Sensors, 2017 The bacterial infection of seeds is one of the most important quality factors affecting yield. Conventional detection methods for bacteria-infected seeds, such as biological, serological, and molecular tests, are not feasible since they require expensive

Advanced Functional Materials, EarlyView.USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Advanced Functional Materials, EarlyView.Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...
