The world faces a number of grand challenges such as climate change, environmental degration, energy, water and food shortages, and public health issues. A nanometer (nm) is one-billionth of a meter. At nanoscale (around 100 nm or less) materials can show marked changes in optical, magnetic, electrical, chemical and physical properties, facts that have been known for some time but are only recently being exploited. Such properties mean that nanotechnology is a very exciting area and may help to find solutions to medical, social and environmental problems which adversely impact upon the quality of life of the people. This research aims to highlight nanotechnology and some of their applications, in addition to some analytical methods and equipments used to measure the structures of nanomaterials and potential risks when dealing with this technology. We also present the results obtained from application of nanotechnology in the field of gas sensors.

The study aims to shed light on the conceptual framework of IOT as a modern term in the field of informatics, and determine its importance and its various applications, In addition to analyzing its contribution on the creation value for different act ors (institutions, governments, individuals ...), Because of its investment and connection to this huge information system, Generally the IoT market revenue is expected to reach $600 B by the end of 2020
The research deals with the development of nanotechnology and its influence on building, in addition to many terms related Nano field; and what it allowed of advanced properties of construction systems and building materials, which influenced the building architectural shape and helped in increasing building efficiency. Nanotechnology added new dimensions to the architectural designer enabled him to embodiment his ideas and fully expressing it , which led to get an infinite magnificence and complicated architectural formations which was impossible to get to it without Nanotechnology.
This research shows a reference study about the technique of the nanotechnology, kinds of nano materials, methods of its manufacturing, its characteristics, its applications, and the role of nano in electronics and optoelectronic. As well this rese arch explains the possibility of manufacturing of a computer with carbon nanotubes and the technique of the paper battery and the capacitor with high capacity. This study gives too an overvieo of the devices and the used technique to in vestigate the nano materials.The article shows too the behavior of the quantum mechanics with the nano electronics. Finally it gives a general overvieo about the quantum devices and their own simulation processes.
