International journal of Nanoparticles and Nanotechnology (IJNN) is a multidisciplinary, peer reviewed journal which includes all the major fields in nanotechnology and Nano science. Nanoscience and nanotechnology brought up an unprecedented excitement in the scientific and engineering communities, especially the last decade. It is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.  International journal of Nanoparticles and Nanotechnology   publishes original research papers during a broad area of nanoscience & engineering. IJNN provides an ideal forum for presenting original reports of theoretical and experimental nanoscience and nanotechnology research. Nanotechnology is a gathering of rising innovations in which the structure of matter is controlled at the nanometer scale, the size of little quantities of molecules, to create novel materials and gadgets that have valuable and one of kind properties. IJNN is naturally multidisciplinary, and welcomes submissions across biological, physical, engineering, and computer sciences. Contributions from both academia and industry are equally encouraged. IJNN also publishes innovative techniques and instrumentation for the fabrication, characterization and testing of nano-enabled devices and technologies, as well as advanced modelling and simulation methods.

We are interested in Organic Synthesis towards Pharmaceutical and Biologically-Active Compounds using Green Chemistry principles. In this regard, my research team is working on the following research fields:

1) Heterogeneous Catalysis Especially Synthetic Nano-Sized Materials or Natural Nano-Biocomposites.

2) Homogeneous Catalysis Especially Organocatalysis (Transition Metal-Free Catalysis). Indeed, some efficient organocatalysts have been introduced to the Chemical Community by our research group. These include Potassium Phthalimide-N-oxyl (POPINO), TetrabutylammoniumPhthalimide-N-oxyl (TBAPINO) and Tetraethylammonium 2-(N-hydroxycarbamoyl) benzoate (TEANHCB).

3) Application of Biopolymers such as chitosan or alginic acid in pure or modified forms. Indeed, this part of our research interest is a bridge between the Heterogeneous Catalysis and Organocatalysis.

4) Environmental and Sustainable Chemistry (Multicomponent Reactions, Rearrangement Reactions, Reactions under Solvent-Free conditions, Reactions in Aqueous Media, Production of Chemicals from Agriculture Supplies, and New Energy Inputs Such as Microwaves, Ultrasound, and Ball Milling).
