Content Title: The Chemistry of Nanotechnology: Exploring the properties and applications of Nano Materials
1-INTRODUCTION
Nanotechnology is transforming numerous areas such as science, medicine, engineering, energy, plastics, and aerospace by manipulating materials at the atomic and molecular levels. With nanotechnology, it becomes feasible to fabricate materials from fundamental units, at the atomic scale, which possess improved electronic, magnetic, optical, and chemical characteristics.
- Technologies that operate, function, or apply at the “nanometer” level are grouped together under the term “Nanotechnology”.
- The term “Nano” derives from the Greek word “Nanos” meaning, “dwarf”.
- Nano materials refer to the substances that have sizes ranging from one to 100 nanometers (nm).
- 1nm=10-9
2-OBJECTIVE
This study focuses on the properties and applications of Nano materials.
3-PROPRTIES OF NANO MATERIALS
3.1-Surface Area
The surface areas of Nano materials are typically greater than that of their bulk equivalents. As the particle size reduces, a larger fraction of atoms or molecules are situated at the surface, which greatly affects their chemical reactivity.
3.2-Magnetism
The magnetic properties of elements may exhibit changes at the Nano scale, allowing a non-magnetic element to attain magnetic characteristics when examined at this scale.
3.3-Quantum Effects
At the Nano scale, materials start to display quantum phenomena, such as quantum confinement, which causes alterations in the electronic properties of Nano materials as their dimensions approach the wavelength of electrons.
3.4-Thermal and Electrical Conductivity
Due the intrinsic properties of Nano materials, exceptional thermal and electrical conductivity which be observed at the Nano scale level when compared to their bulk counterparts. A notable example of this phenomenon is graphene, which is derived from graphite.
3.5-Mechanical Properties
Nano materials demonstrate remarkable mechanical properties, which are not present in their larger-scale equivalents.
3.6-Antimicrobial Activity
Certain Nano materials exhibit antiviral, antibacterial, and antifungal characteristics, demonstrating a remarkable ability to combat diseases associated with pathogens. For instance, Silver Nanoparticles are recognized for their extensive antimicrobial activity.
