Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Phosphine-Catalyzed (4 + 2) Annulation of Sulfonamido-Substituted Enones with 1,1-Dicyanoalkenes: Synthesis of Piperidine Derivatives

, 2021
The δ-sulfonamido-substituted enones were employed as phosphine acceptor in phosphine-catalyzed (4 + 2) annulation of 1,1-dicyanoalkenes. They served as a four-membered synthon to react with 1,1-dicyanoalkenes under mild reaction conditions, producing ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Phosphine-Catalyzed Intramolecular Cyclizations of α‑Nitroethyl­allenoates Forming (Z)‑Furanone Oximes

, 2016
A novel and efficient phosphine-catalyzed intramolecular cyclization of α-nitroethyl­allenic esters is reported. This process appears to be practical for the stereoselective syntheses of (Z)-furan-2­(3H)-one oxime derivatives in excellent yields ...

Phosphine-Catalyzed Aryne Oligomerization: Direct Access to ,Bisfunctionalized Oligo(ortho-arylenes)

, 2021
A phosphine-catalyzed oligomerization of arynes using selenocyanates was developed. The use of JohnPhos as a bulky phosphine is the key to accessing α,ω-bisfunctionalized oligo­(ortho-arylenes) with RSe as the substituent at one terminus and CN as the ...
