A onestep method which involves exfoliating graphite materials (GIMs) off into graphene materials (GEMs) in aqueous suspension of CL20 and forming CL20/graphene materials (CL20/GEMs) composites by using ball milling is presented. The conversion of mixtures to composite form was monitored by scanning electron microscopy (SEM) and powder Xray diffraction (XRD).
Singlecrystalline ZnO nanostructures were synthesized by solvothermal method using methanol as solvent. The effect of counterions of zinc salts (nitrate, acetate, and chloride) on the morphology of ZnO nanostructures was investigated. ZnO nanorods (NRs) were formed for all kinds of zinc salts except zinc chloride, where nanoparticles (NPs) were formed.
In various other industrial applications, powders are processed with a spray drying method [16] . In the spray dr ying method, fine material is agglomerated to larger particles. Depending on the process parameters, shape, size, size distribution and qualities of the agglomerates can be modified. In this study, the goal was to manufac
It is good to see that the fabrication of micrometer‐sized Si/G/C composites mainly relies on simple, low‐cost, and easily scaled‐up manufacturing methods such as ball milling/mechanical milling, spray drying, CVD, wet processing, and combinations of these methods. However, the whole synthesis processes are generally complicated.
Nanoparticles are claimed which consist of % by weight of alumina and % by weight of metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminum chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.

Abstract. This is a review and an overview on hydrothermal synthesis of fine oxide powders. The term hydr othermal today includes methods which involve water at pressures (from 1 atm –several kilobars) and high te mperatures from 100 –10,000°C. Hydrothermal is one of t he best methods to produce pure fine oxide powders.

In this report, we first investigated the selfassembly processes of charged colloidal nanoparticles in charged droplets during spraydrying. Silica nanoparticles and polystyrene spheres are used as a model system. To induce a positive or a negative charge on the droplets, we used an electrospray method.
Nanoparticles are materials that are confined to the nanoscale in all three dimensions. Engineered nanoparticles play an important role in nanotechnology. The specific properties of nanoparticles is defined by particle size, chemical composition, crystallinity and shape. During production these can be controlled by temperature, pHvalue, concentration, chemical composition, surface ...
