Hierarchical spindle-like γ-Al2O3 materials were prepared in the form of fray ended bundles
of twisted nanoflakes by a non-template hydrothermal synthesis and sequential calcination …

The fabrication of dense alumina fibers at low cost by sol-gel and electrospinning, using
aluminum nitrate as precursor is reported. Polyvinyl pyrrolidone was used as spinning …

The adsorption of U (VI) onto dried and pyrolyzed tea and coffee wastes was investigated.
The adsorption properties of the materials were characterized by measuring uranium uptake …

Macroporous α-alumina can be obtained by polymer-induced phase separation during the
sol-gel process based on dissolved aluminum salts. Polyethylene oxide (PEO) acts as …

In the research, microwave–ultraviolet (MW–UV) irradiation was applied for the regeneration
of MnO x/Al 2 O 3 which adsorbed glyphosate. The mineralisation percentage of the …

We adapt the sol–gel process to synthesize monodisperse metallic iron (80–155μm), iron
oxide (117–200μm), xerogel (130–224μm), and-PVA hydrogel (300–600μm) microspheres …

A simple sol-gel method and external gelatinization method of hollow alumina spheres
synthesis were developed in this study. The spheres were modified with polyethyleneimine …

In the present investigation, γ-alumina nanoparticles with high specific surface area (351
m2/g) and relatively narrow pore size distribution was prepared using sol-gel method in the …

Ozone initiated oxidation of environmentally unfriendly organic compounds is one of the
powerful tools that is utilized to convert and/or completely mineralize these substances. Here …

In this paper, spherical, smooth and unagglomerated ultrafine amorphous powder particles
were prepared by ultrasonic spray pyrolysis (USP) of easy-handling aqueous aluminum …
