Nitro-Grela-type complexes containing iodides – robust and selective catalysts for olefin metathesis under challenging conditions

Beilstein Journal of Organic Chemistry, 2015
Iodide-containing nitro-Grela-type catalysts have been synthesized and applied to ring closing metathesis (RCM) and cross metathesis (CM) reactions. These new catalysts have exhibited improved efficiency in the transformation of sterically, non-demanding

Thermally Conductive and Electrically Insulating Thermal Interface Materials for Advanced Packaging: From Filler and Interface Engineering to Thermal Networks

Electron, EarlyView.
This review establishes a hierarchical framework linking physical fundamentals, filler and interface engineering, and thermal‐network construction for thermally conductive yet electrically insulating thermal interface materials. It identifies package‐level co‐optimization of heat transport, electrical insulation, processability, and reliability as the ...

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.
