Abstract. Nanotechnology seems to hold the key that allows construction and building materials to replicate the features of natural systems improved until perfection during millions of years. This paper reviews current knowledge about nanotechnology and nanomaterials used by the construction industry. It covers the nanoscale analysis of Portland. One of the main disadvantages of the bactericidal effect associated with photocatalysis relates to the need of UV radiation with a wavelength between 200 nm and 400 nm, however, recent findings show some possibilities in the development of composite materials with photocatalytic properties even when exposed to visible light , .The use of titanium and trioxide tungsten based films showed high photocatalytic capacity under visible light above 400 nm , The goal of nanotechnology is to be able to manipulate materials at the atomic level to build the smallest possible electromechanical devices, given the physical limitations of matter. Much of the mechanical systems we know how to build will be transferred to the molecular level as some atomic analogy Agriculture has also gotten benefits from nanosciences and biotechnology, enhancing the production and protection of crops for affordable and innocuous food. Other areas such as medicine, manufacture of daily use products, electronic, among others, also have been benefited by the joint findings between nanoscience, nanotechnology, and biotechnology Nanotechnology is a rapidly developing area in science involved with manipulating matter at the atomic or molecular level. Nanotechnology is typically defined at a scale on the order of less than approximately 100 nm. Matter possesses unique properties at these size levels that are neither Newtonian

Nanotechnology has the ability to improve catalysis and that is helping at improving fuel production efficiency. It enables higher efficiency combustion and decreased friction which results in lower energy consumption in vehicles and power plants. Nanotechnology has found application in gas and oil extraction Producers in developing countries could also be disadvantaged by the replacement of natural products (including rubber, cotton, coffee and tea) by developments in nanotechnology. These natural products are important export crops for developing countries, and many farmers' livelihoods depend on them Nanotechnology can easily merge with other technologies and modify, endorse or clarify any existing scientific concept, which is why it is so called a platform technology (Shmidt, 2007). The use of nanotechnology in the future is expected to expand into numerous industrial applications and help decrease production costs b

Disadvantages: Impossible to extract an exact amount for input; Inability to compare multiple points of data in one chart; Stem and Leaf Plots. Stem and leaf plots are charts that allow you to split data values into a stem and leaf pattern. This usually consists of putting the first value into the stem column and last digits into the leaf. Disadvantages of remote sensing: Remote sensing is a fairly expensive method of analysis especially when measuring or analyzing smaller areas. Remote sensing requires a special kind of training to analyze the images. It is therefore expensive in the long run to use remote sensing technology since extra training must be accorded to the users of. Nanotechnology - Chemistry bibliographies - in Harvard style .
