Introduction

In advanced technological era corrosion is still considered a major problem because it is the main cause of industrial failures and loss of billions of dollars annually for preventive maintenance and restoration of metal substrates. Corrosion resistant paints protect metal components against degradation due to the moisture, salt spray, oxidation or exposure to a variety of industrial chemicals. Anti-corrosion coating allows for added protection of metal surfaces and acts as a barrier to inhibit the contact between chemical compounds or corrosive materials. Addition of nanoparticles as fillers to the polymeric paints not only increases their efficiency in terms of corrosion resistance but also improves their mechanical properties.

Introduction

ABS polymer is composed of three different monomers, including Acrylonitrile, Butadiene and Styrene, in which each monomer gives unique properties to the final product. Some of these properties are transparency, flexibility, and polarity and chemical resistance which are created by styrene, butadiene, and acrylonitrile, respectively. Therefore, by changing the percentage of each monomer in composition, several grades of ABS can be produced. This material has different applications such as plastic parts that are used in home appliances. ABS masterbatch granules are produced using modified antibacterial nanomaterials. To gain better properties which facilitate the use of ABS in fabrication of components with antibacterial feature, this material can also be mixed with other polymers, such as polyvinyl chloride or polycarbonate.

Introduction

Geomembrane is a very low permeable synthetic membrane which is used in various geotechnical engineering projects to control water or gas leakage. It has been confirmed that for this application, geomembranes are more efficacious than other traditional products such as concrete, asphalt, and compacted clay. This product has a wide range of properties, i.e. physical, mechanical and chemical resistance, to protect our environment and water resources. It is worth mentioning that the antibacterial activity of polymers reinforced with silver nanoparticles is stable and its high antibacterial efficiency has been observed against different species of bacteria. Silver ions and its compounds can kill a wide range of bacteria, while they have no toxic effect to the human body. Therefore, the use of silver in different forms is a common method of protection against bacteria. 

Introduction

Petroleum resources are limited and the excessive use of non-biodegradable polymers has caused serious environmental problems. Therefore, degradable and/or biodegradable polymers have received more attention these days. Since synthetic polymers are expensive, the focus is mainly on natural polymers which are inherently biodegradable and can be promising candidates to meet different requirements. Among the natural polymers, starch is of main interest. It is regenerated from carbon dioxide and water by photosynthesis in plants. Due to its complete biodegradability, low cost, and renewability, starch is considered as a promising candidate for developing sustainable materials. Addition of starch to the synthetic polymers creates biodegradable feature but decreases mechanical properties. To deal with this problem, nanofibers are added to the polymers.

Introduction

Desalination is considered as a common solution for the regions with shortage of fresh water resources. There are various methods for brackish and sea water desalination.

PNF Company has developed modified electro dialysis technology as an appropriate and efficient for desalination.

The developed process is an electrochemical technique in which the ionic contaminants are removed from the aqueous solution. In this method, separation of salt from water is conducted in the presence of anionic and cationic membranes under the influence of an electric field. 

Introduction

This product is Paclitaxel albumin bound (Abraxane). Paclitaxel is a natural anti-cancer material which inhibits the process of cell division and growth of cancer cells. This drug uses albumin as carrier of water insoluble molecules in the body which selectively accumulates in tumor tissues. Unlike other solvent based chemotherapy drugs, this drug has no side effects because the effective anti-cancer material, paclitaxel, is placed inside albumin.

Introduction

This device is a colored wastewater treatment apparatus using nanostructured graphite electrodes which operates based on electrolysis process. These electrodes are produced by cold plasma method. Carbon compounds, especially graphite, have great properties which make them interesting for utilization as a cathode electrode. Using different types of modification methods in different systems make colored compounds, p-nitrophenol contaminants, azo dyes elimination and hydrogen peroxide production possible. Among electrode modification methods, plasma- based methods are generally cheap, clean and easy, which require less time. In order to purify the wastewater, firstly the carbon electrodes are modified by the plasma process to increase specific surface area and H2O2 production on the surface of the electrodes and then, modified electrodes are used as a cathode for electrolysis of wastewater.
