1. Environmental and health hazards of chemicals in plastic polymers and products
Abstract : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. READ MORE

2. Low Band-Gap Conjugated Polymers for Plastic Solar Cells
Abstract : Today, fossil fuels like coal, oil, and natural gas are used for more than 60% of the world's electricity production. These fuels have a very negative impact on the environment and many researchers agree that the earth's climate is changing as a consequence of fossil fuel emissions. READ MORE

3. Thermoset polymers and coatings subjected to high compressive loads
Abstract : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed.

4. Antioxidant-Impregnated Polymers / Antioxidant Ability and Interactions with Food
Abstract : Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. READ MORE

5. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris
Abstract : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. READ MORE
