Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology

open access: yesAdvanced Photonics Research, EarlyView.
This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Life in Hot Carbon Monoxide: The Complete Genome Sequence of Carboxydothermus hydrogenoformans Z-2901 [PDF]

open access: yes, 2005
We report here the sequencing and analysis of the genome of the thermophilic bacterium Carboxydothermus hydrogenoformans Z-2901. This species is a model for studies of hydrogenogens, which are diverse bacteria and archaea that grow anaerobically ...

Beam Combining of a Tunable Tilted Quantum Cascade Laser Array

open access: yesAdvanced Photonics Research, EarlyView.
The four‐channel tilted waveguide with varying angles in the quantum cascade laser array, achieving a free tuning range of 100 nm and common‐aperture output simultaneously, is reported. The fabrication eliminates the necessity of electron‐beam lithography and is very promising for mass production in gas sensing industry.

Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...
