Limited, finite, contaminated, unavailable or expensive, water divides people all around the globe. We all cannot do without water for long, but can for long enough to fight for it. This commonsensical narration of water conflicts, however, follows a pattern of scarcity and necessity that is remarkably unvaried despite different social and geographical

Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2015
For many tasks in evaluation campaigns, especially those modeling narrow domain-specific challenges, lack of participation leads to a potential pooling bias due to the scarce number of pooled runs. It is well known that the reliability of a test collection is proportional to the number of topics and relevance assessments provided for each topic, but ...

Water Splitting by Cooperative Catalysis
Angewandte Chemie International Edition, 2009A mononuclear Ru complex is shown to efficiently split water into H2 and O2 in consecutive steps through a heat- and light-driven process (see picture). Thermally driven H2 formation involves the aid of a non-innocent ligand scaffold, while dioxygen is generated by initial photochemically induced reductive elimination of hydrogen peroxide.

Photocatalytic Water Splitting
2016This chapter deals with the topic of photocatalytic water splitting. Photosynthesis in nature is discussed leading into artificial photosynthesis in the lab. The basic principles of photocatalytic water splitting are introduced, followed by materials used for artificial photosynthesis, visible-light-driven photocatalysis, and dye-sensitized visible ...

Water splitting means a chemical transformation that separates water into its elements which are molecular oxygen (O2) and molecular hydrogen (H2). The transformation can be done by various processes such as: electrolysis, photochemical, photocatalytic, thermal decomposition.

Chemistry Widespread use of functional electrocatalytic water-splitting systems in conjunction with solar power infrastructure will probably require a composition of Earth-abundant materials that remain stable under the reaction conditions and operate efficiently at minimal overpotential (a measure of how much of the input energy gets stored in the ...
