VEROGLAZE – color and protection for metal

Piesslinger-Schweiger S., POLIGRAT GmbH, DE

VEROGLAZE is a new revolutionary method, which applies long living hard and dense protective layers of quartz glass onto solid surfaces of numerous materials like Steel, Stainless Steel, Aluminum, Copper Alloys, Zinc, concrete, ceramics, stone, [...]

Degradability of polymeric composites (ENR/PLA) from renewable resources

Masek A., Zaborski M., Lodz University of Technology, PL

In our research, we reported on biodegradable composites exhibiting specificity properties by melt blending of polylactide (PLA), one of the commercially available biodegradable material, and epoxidized natural rubber (ENR). Blending of ENR with different types [...]

Natural polyphenols as pro-ecological antioxidants and pigments for polymer composites

Masek A., Zaborski M., Lodz University of Technology, PL

In our studies, we propose the use of natural, pro-ecological substances such as polyphenols to protect elastomers against ageing. This natural compounds were incorporated into ethylene-norbornene (COC-material is commercially available under the name of TOPAS); [...]

Ageing of elastomeric composites with natural antioxidants

Masek A., Zaborski M., Institute of Polymer and Dye Technology, PL

The natural antioxidants which were added to ethylene-octene elastomer (polyolefin elastomer-Engage). Vulcanizates were then subjected to numerous ageing: weathering (climat of Floryda), UV (0,7 W/m2), thermo-oxidation ageing (1000C/10days) and thermal-shock (-600C/+1000C) as a function of [...]

Loss of Elasticity of Ageing Epithelial Cells, and Its Possible Reversal

Sokolov I., Woodworth C.D., Clarkson University, US

We investigated human epithelial cells of different age in-vitro by means of the atomic force microscopy. We found that older cells are considerably (~2-10 times) more rigid that younger cells. This helps to explain why [...]
