Coupled Optical Response of Armchair Graphene Nanoribbons and Single Wall Carbon Nanotube Hybrid Structures

open access: yesAdvanced Optical Materials, EarlyView.
A strong interaction between the five‐armchair graphene nanoribbons (GNRs) and the encapsulating single‐walled carbon nanotubes is identified. A reduction of the bandgap of the hybrid structure as well as additional proof for the single H‐terminations of the GNRs are confirmed through a combination of optical absorbance spectroscopy and density ...

Regio‐, Stereoselective, Aerobic and Metal‐Free Synthesis of Z‐Vinyl Sulfides: One‐Pot Hydroiodination of Internal Alkynes and in situ Sulfenylations

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A novel, metal‐free, air‐ and moisture‐compatible one‐pot tandem protocol for the regio‐ and stereoselective synthesis of Z‐vinyl sulfides (achieving yields up to 99%), is reported. This straightforward and efficient process combines the selective hydroiodination of internal alkynes, promoted by the eutectic mixture choline iodide (ChI)/p‐TsOH

Printed Recyclable and Flexible Thermocouple Temperature Sensors

open access: yesAdvanced Sensor Research, EarlyView.
Printed recyclable thermocouple sensors with low cost, easy processing, and compatibility with mass production are developed. Using re‐dissolvable polymeric binders, the printed sensors decompose without harsh treatments, while ferromagnetic Ni flakes enable efficient magnetic separation of materials.
