Cation modified silicates for catalytic production of phenol from benzene [PDF]
, 2017 In this work, we produced phenol directly from benzene using silicates modified with Al and Fe. The preparation of Al and Fe-silicates was done at 373 K by mixing a silicate solution with Al and Fe sources and the resulting material were dried at 373 K ...

Advanced Science, EarlyView.This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This
