2 What is it that we do? We provide environmentally friendly solutions for protecting a wide range of common building surfaces We Tune the Nano-world to Serve the Macro-world

3 What is nanotechnology? 10 5 nm 10 4 nm bulk 10 3 nm 10 2 nm 10 nm 1 nm 1 Å nanoparticles quantum dots molecules SurfaShield nanoparticles are 25nm in diameter: 16 billion could fit on the surface of a Euro cent!

4 Nanotechnology based protection against water, moisture, stains, mould and heat transfer

5 Applications across the globe Monastiraki Square (Greece) Copenhagen Concert Hall (Denmark) Byzantine Churches (Cyprus) Øleng Beton (Norway)

8 SurfaPore C Application Process on Cement or Mortar Grout: Mixing: Mix diluted SurfaPore C with cement or mortar grout, instead of water. No other modification is required. The final product is water protected after 24 hours. Surface Application: Apply diluted SurfaPore C on the cement or mortar grout surface, using a roller or spraying. No other modification is required. The final product is water protected after 24 hours. Simple, Quick, Trouble Free! SurfaPore C is resistant under UV irradiation, salts, ageing and acid rain attacks. More than 96% of water exclusion is achieved.

9 SurfaPore C The need: Water induces corrosion of cement surfaces and development of efflorescence stains. Unprotected mortar grout wall cladding causes failures and deterioration of decorative surfaces. Mould growth. The solution: SurfaPore C shields surfaces against water penetration, whilst it enables respiration phenomena and moisture removal. Cement surfaces retain strength and original appearance.

10 The problem: Save Energy in a Simple Cost Effective Manner Opportunity: Start blocking heat on the very surface of the wall The solution: A nanotechnology and microtechnology paint additive that: Reflects Heat Radiation before it enters the wall Blocks heat on the surface Minimizes humidity and therefore makes walls better insulators

11 The need: Paints absorb water and allow heat transfer Blocks and reflects heat at the surface of the wall Water absorption makes heat transfer easier Mould growth due to condensation The solution: SurfaPore ThermoDry blocks heat transfer and humidity.

12 Surfapore ThermoDry Treated Regular Paint Incident heat & radiation Surface temperature T 1 Wall T 2 Incident heat & radiation T 1 Temperature difference due to Reflection & Paint conductivity T 1 -T 3 >> T 1- T 2 Increased temperature difference due to relative humidity reduction T 3

13 Surfapore ThermoDry Treated Regular Paint 对流热 & 辐射热 Incident heat & radiation Surface temperature T 1 Wall 墙壁表面温度 T 1 T 2 Incident heat & radiation T 1 Temperature difference due to Reflection & Paint conductivity T 1 -T 3 >> T 1- T 2 Increased temperature difference due to relative humidity reduction T 3

14 Triple Protection 1. Thermal radiation reflectance 2. Resistance in heat transfer 3. Water repellence Reflects 92,35% of infrared heat radiation Reduces paint thermal conductivity by at least 4 times (0,1292 W/(mK)) Extends paint life Increases paint volume by 60% Improves applicability of paint

15 Maintains Internal Temperature Keeps Heat Out

HOMEWORK 4 = G. In order to plot the stress versus the stretch we define a normalized stretch:

HOMEWORK 4 = G. In order to plot the stress versus the stretch we define a normalized stretch: HOMEWORK 4 Problem a For the fast loading case, we want to derive the relationship between P zz and λ z. We know that the nominal stress is expressed as: P zz = ψ λ z where λ z = λ λ z. Therefore, applying
