Synthesis of Sulfated Sn–Zr Mesoporous Catalysts for the Selective Dehydration of Hexose‐Type Monosaccharides

open access: yesChemistryOpen, EarlyView.
The synthesized SO4/Sn–Zr–SBA‐15 shows high activity in fructose‐to‐5‐hydroxymethylfurfural (HMF) dehydration. Acid sites with positive synergy effect between metals and SO4= improve catalytic behavior Synthesis of combined Brønsted and Lewis acid sites in SBA‐15 by Zr and Sn incorporation onto the mesoporous support, followed by a sulfation procedure ...

Dynamic Behavior of Pressure‐Responsive Microphase‐Separated Diblock Copolymers

open access: yesJournal of Polymer Science, EarlyView.
A dynamic theory based on a lattice vacancy model provides quantitative physical insights into nonequilibrium behavior and flow properties of pressure‐responsive block copolymers. ABSTRACT The dynamics of pressure‐induced order–disorder transitions in diblock copolymer systems and their effect on the flow properties are investigated.
