Not like typical MCM-41 mesoporous materials, it is found that results of analysis are a little different and morphology of mesoporous materials synthesized in acid media does not rely on silicon sources, regardless of organic or inorganic silicon source.
Introduction Mesoporous materials are generall synthesized in alkaline hydrothemal method.
Conclusion In acid media, mesoporous materials can be made from inorganic silicon source like organic silicon source on mild condition.

Simultaneously, the service behavior of the bamboo/steel slabs is pecfect and there is execllent composite effect between the two different materials.
And the strain is basically the same at the interface of the two kinds of materials.
Bamboo/steel composite beam composites with two different plate materials by structural adhesive.
Because the thickness of composite beam's flange plate is large relatively, the strain gradient changes intersection between surfaces of two different materials.
