10 Nanotechnology What is Nanotechnology? Nano = nánnos (greek: dwarf) Prefix for SI-Units: 1 nm = 10-9 m. The proportion of 1 m compared to 1 nm is equal to the diameter of earth to a 1 cent coin

11 Nanotechnology Definition of Nanotechnology: Technologies that deal with the research, development or production of objects, that have a maximum size of 100 nm in at least one dimension are called nanotechnologies. What does this mean in our case? A very large surface compared to the volume Surface properties are getting more important New chemical and physical properties

12 Nanotechnology Application area of Nanotechnoloy: Lacquer (anti-dirt sealing, UV-protection..) Computer (Intel-Chips: < 32 nm) Textiles (water barrier, anti-dirt) Pest management (Nano instead of poison) Medicine (selective action) Cosmetics (TiO 2 as UV-protection, toothpaste, ) Food (color, taste, )

13 VTA Nanofloc VTA Nanofloc is a : Nanostructured product (particle size: 70 nm) with new properties. Advantages of the nano structure: - a very small volume diffusion into the floc is possible - a large active surface the charge is transported into the floc flocs with a high density maximizing the settling speed

15 VTA Nanofloc Nano-scale iron particles are sub-micrometer particles of iron metal. They are highly reactive because of their large surface area. In the presence of oxygen and water, they rapidly oxidize to form free iron. They are widely used in medical and laboratory applications and have also been studied for remediation of industrial sites contaminated with chlorinated organic compounds. 2 Fe 0 (s) + 4 H + (aq) + O 2 (aq) 2 Fe 2+ (aq) + 2 H 2 O(l) Fe 0 (s) + 2 H 2 O (aq) Fe 2+ (aq) + H 2 (g) + 2 OH - (aq) H 2 S 2H + (aq) + S 2- (aq) Fe 2+ (aq) + S 2- (aq) FeS (s ) precipitant, black in colour
