Broadband Fourier-Transform Optical Photothermal Infrared Spectroscopy and Imaging [PDF]

arXiv
Optical photothermal microscopy is a powerful, emerging method that overcomes the diffraction limit in infrared hyperspectral imaging by utilizing a visible probe laser beam to detect local temperature-induced modulation at the visible diffraction limit.

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

Advanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Surface Reconstruction Induced by Preconditioning in Different Electrolytes Impacts Electrooxidation of Solketal on Multi‐Metal‐Based Catalysts

Advanced Functional Materials, EarlyView.
The electrocatalytic activity and stability of CoNiFeCu (1:1:1:0.5) toward glycerol and solketal electrooxidation are strongly impacted by the electrolyte composition used during the catalyst activation. Solketal tends to inhibit oxyhydroxide formation and suppresses Cu leaching, leading to increased activity while also supporting increased production ...

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

Advanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...

Symbiotic Miras vs. Planetary Nebulae in the Near Infrared [PDF]

ASP Conf.Ser. 303 (2003) 446, 2002
While symbiotic Miras and planetary nebulae are hard to distinguish by optical spectroscopy, their near infrared colors differ. We propose the near infrared two-color diagram to be an excellent tool to easily distinguish these two classes of objects.
