Production and Characterization of Open Cell Cordierite from Boron and Waste Materials by Geopolymer Method for the Emission After Treatment System of Diesel Engines

Global Challenges, EarlyView.
Open porous geopolymer‐based cordierite materials are produced due to the porous structure, temperature resistance, easy and low cost applications of geopolymer. For the composition of cordierite, waste boron clay, metakaolin, fly ash and magnesium carbonate are used, while keeping the geopolymerization temperature constant, sodium silicate, sodium ...

Efficient Oxidative Polymerization of Hydroxytyrosol Using Horseradish Peroxidase Immobilized on a Magnetic Silica‐Coated Nanocatalyst

Global Challenges, EarlyView.
A magnetic Fe₃O₄@SiO₂@APTES@GA nanocatalyst is synthesized for horseradish peroxidase (HRP) immobilization, enabling efficient oxidative polymerization of hydroxytyrosol under mild conditions. The biocatalyst demonstrates high thermal and pH stability, strong reusability over 10 cycles, and effective polymerization performance.
