چکیده
Ordered mesoporous carbonaceous spheres with variable structures have been successfully prepared by using phenolic oligomers as a carbon precursor and amphiphilic triblock copolymers as a template via a one-step aerosol-assisted organic-organic self-assembly method.

One-pot synthesis of silicon nanoparticles trapped in ordered mesoporous carbon for use as an anode material in lithium-ion batteries.
Silicon nanoparticles trapped in an ordered mesoporous carbon composite were prepared by a one-step self-assembly with solvent evaporation using the triblock copolymer Pluronic F127 and a resorcinol-formaldehyde polymer as the templating agent and carbon precursor respectively. Such a one-pot synthesis of Si/ordered mesoporous carbon nanocomposite is suitable for large-scale synthesis. Characte...

In this paper, 4,4ʹ-bipyridinium dichloride supported SBA-15 (SBA@BiPy2+ 2Cl-) was used for the synthesis of dihydropyrimidinones. The synthesized catalyst was characterized by FT-IR spectroscopy, scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Thermogravimetric analysis (TGA). This nanocomposite was shown to be an efficient heterogeneous ca...
متن کاملAerosol-assisted self-assembly of single-crystal core/nanoporous shell particles as model controlled release capsules.
Single-crystal NaCl core/nanoporous shell particles have been synthesized by evaporation-induced self-assembly. By variation of the hydrophobicity of the mesoporous shell, we can control the release rates by over 4 orders of magnitude.
متن کاملPatterning Porous Oxides within Microchannel Networks
Nature abounds in hierarchical structures that are formed through highly coupled and often concurrent synthesis and assembly processes over both molecular and long-range length scales. The existence of these structures such as abalones and diatoms has both biological and evolutionary significance. It has been a long-sought goal to mimic the natural processes responsible for these exquisite arch...
