Nanofiltration : towards a breakthrough

International conference on System Science and Simulation in Engineering - Proceedings 2010, Pages 71-76Membrane unit operations with a pressure gradient as the driving force have already known a breakthrough in the past decades. Reverse osmosis in the 60s, Ultrafiltration in the 70s, Crossflow Microfiltration in the 90s. The newcomer among those methods, the Nanofiltration strives also to gain a wide application field that would justify the occurrence of a breakthrough! Recent experimental work in our Laboratory of Transport Phenomena and Applied Thermodynamics, at the Technical University of Crete, show that this field of wide application is the brackish water desalinatio

Rural Women and the Development of the Agritouristic Cooperatives in Greece: The Case of Petra, Lesvos

The role of rural women in Greece is changing gradually within a broad framework of socio-economic transformations the rural sector has been facing in the recent years. This article is concerned with the broadening of rural women's activities to include matters of public life such as the women's agritouristic cooperatives. The moving force behind the development of these cooperatives has been the General Secretariat for Equality as a way to make known the socio-economic role of women in rural communities and to enhance their income. The first cooperative of this type was established in 1984 in Petra, a small village in the island of Lesvos. In its twelve years of existence, this project has seen the smooth shift of this community from an agricultural economy to an agritouristic one, a pattern that has been quite fulfilling in terms of occupation and income for the local population

Catalytic Transfer Deuteration and Hydrodeuteration: Emerging Techniques to Selectively Transform Alkenes and Alkynes to Deuterated Alkanes

Increasing demand for deuterium-labeled organic molecules has spurred a renewed interest in selective methods for deuterium installation. Catalytic transfer deuteration and transfer hydrodeuteration are emerging as powerful techniques for the selective incorporation of deuterium into small molecules. These reactions not only obviate the use of D2 gas and pressurized reaction setups but provide new opportunities for selectively installing deuterium into small molecules. Commercial or readily synthesized deuterium donors are typically employed as easy-to-handle reagents for transfer deuteration and hydrodeuteration reactions. In this minireview, recent advances in the catalytic transfer deuteration and hydrodeuteration of alkenes and alkynes for the selective synthesis of deuterated alkanes will be discussed
