ZnO-based hollow microspheres: Biopolymer-assisted assemblies from ZnO nanorods

Article Abstract:

A new synthetic route is developed for three-dimensional (3D) ZnO-based hollow microspheres by a facile solution-based method through a water-soluble biopolymer (sodium aliginate) assisted assembly from ZnO nanorods. The results have shown that the biopolymer-directed crystal growth and mediated self-assembly of nanocrystals have provided promising routes to rational synthesis of various ordered inorganic and inorganic-organic hybrid materials with complex form and structural specialization.

Interlayer expansion and mechanisms of anion sorption of Na-montmorillonite modified by cetylpyridinium chloride: A Monte Carlo study

Article Abstract:

The experimentally got suggestions that CP(super +) ions build monomolecular, bimolecular, or pseudotrimolecular layers depend on their content in interlayer spaces of the CP(super +) modified montmorillonite is discussed. It was concluded that interlayer sorption of inorganic anions of CP(super +) modified montmorillonite needs that CP(super +) ions possess a pseudotrimolecular arrangement in its interlayer space.

Determination of carbon nanotube density by gradient sedimentation

Article Abstract:

The densities of carbon nanotubes (CNTs) that have various structures are measured with the equilibrium density gradient sedimentation technique using sodium metatungstate as the gradient-generating agent. The differences in structural features of CNTs result in distinguishable differences in densities and they are found to be in agreement with theoretical computations based on their structures.
