The results of study of the structure and properties of high-temperature oleogreases containing thickener components that can be derived from renewable natural materials are presented. The ...constitution of the primary structures of the oleogreases prepared by using calcium soaps of fatty acids of poultry fat and palm oil as the organic component of the thickener is established. It is proved that the distinctive properties of the oleogreases are ensured by the thickener system based on a dispersion of calcium carbonate and a natural surfactant. In bulk-mechanical, antioxidative, tribological, and protective properties, the obtained oleogreases are not inferior to commercial superalkaline sulfonate lubricant.
This presentation reports recent advancement of cellulose nanocrystals and cellulose nanofibers, followed by their possibilities as well as challenges for smart optics materials. Natural behaviors, ...extraction, modification of cellulose nanocrystals and fibers are explained and their synthesis with nanomaterials is introduced, which is necessary to meet the technological requirements for smart optics. Also, its possibilities and challenges for smart optics materials are addressed.

Today, the environment has become a main subject in lots of science disciplines and the industrial development due to the global warming. This paper presents the analysis of the tendency of Green ...Architecture in France on the threes axes: Regulations and Approach for the Sustainable Architecture (Certificate and Standard), Renewable Materials (Green Materials) and Strategies (Equipments) of Sustainable Technology. The definition of ‘Green Architecture’ will be cited in the introduction and the question of the interdisciplinary for the technological development in ‘Green Architecture’ will be raised up in the conclusion.
The aim of this research was to develop an improved recycled asphalt pavement by using reinforcement sheeting to decrease the shortcomings of reclaimed asphalt pavement (RAP), and take advantage of ...its merits. Evaluation tests showed that the use of reinforcement sheeting in combination with recycled asphalt mixture resulted in a paving material that significantly outperforms virgin asphalt mixture in rutting resistance, crack resistance and serviceability. Concern for the state of the environment has grown considerably in recent years throughout the world. Road construction is no exception to this. This report was submitted in the hope that the proposals it contains would contribute to further promotion and expansion of effective use of recycled asphalt mixture.
