Green Synthesis of Stereodefined Tri- and Tetrasubstituted Alkenes via 100% Atomeconomic and Regio-, and Stereoselective Halo-chalcogenation and Sulfonylation of Alkynes

open access: yesCHIMIA
Achieving 100% atom economy in an organic transformation is a challenging task but it is always desirable in the context of green chemistry. Difunctionalization of alkynes using a bifunctional reagent is a useful strategy to achieve 100% atom economy ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...
