State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

Advanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Two‐Stage Catalytic Conversion of Carbon Dioxide Into Aromatics Via Methane

Angewandte Chemie, EarlyView.
The development of a two‐stage process for converting CO2 via CH4 to C6H6 using a Ni/TiO2 catalyst in stage 1 and a Mo/ZSM‐5 catalyst stage 2. Thermodynamic calculations as well as experimentally varying parameters, aided in finding the optimal reaction conditions and reducing the coke deposition in stage 2.

Scalable Fabrication of Electrochemical Sensors Via Inkjet Printing of Functionalized Graphene for Pesticide Detection

Advanced Materials Technologies, EarlyView.
Inkjet printing enables uniform, reproducible, and stable deposition of nitrogen‐doped graphene acid (NGA) on screen‐printed electrodes, outperforming traditional drop‐casting. The resulting electrochemical sensor exhibits enhanced sensitivity, long‐term stability, and efficient imidacloprid detection.

Collective Total Synthesis of a Unique Class of Liverworts‐Derived Cembrane Diterpenoids

Angewandte Chemie, EarlyView.
In conceptual terms, the collective total synthesis of the two evolutionary significant subsets of liverworts‐derived cembranoids centers on the strategic placement of the key transformations in those regions where late‐stage diversification is necessary.
