As scientists and engineers, we publish papers because we want others to read and learn from our work. We hope to make substantial contributions to the body of knowledge. For this reason, it is critical that the journals we publish in are widely read and cited. Since its start on 9 May2011, the editorial board and guest editors have been working to make Catalysts an outstanding journal that receives the highest quality submissions. Our go...

Catalysts | Special Issue : Electrocatalysis in Fuel Cells Fuel cells are expected to come into widespread commercial use in the areas of transportation, stationary and portable power generation, and thus will help solve the global problems of energy supply and clean environment. Despite their great promise, commercialization has been hindered by lower than predicted efficiencies and the high cost of electrocatalysts in the electrodes....

JMSE | Special Issue : Tsunami Science and Engineering Recent earthquake-tsunamis including the 2004 Indian Ocean Tsunami, with over 230, 000 casualties, and the 2011 Tohoku Tsunami in Japan, with over 18, 500 people missing or dead, serve as tragic reminders that such waves pose a major natural hazard to human beings. Landslide-tsunamis, including the 1958 Lituya Bay case, may exceed 150 m in height and if similar waves are generated ...

The articles in this volume collectively represent the latest advances in how people think of social dilemma problems, how we may be able to enhance cooperation and reduce free-riding in such problems and how we can extend the lessons learned to a host of other similar issues facing us. We have learned, for instance, that a "take" frame does not necessarily lead to lower cooperation compared to a "give" frame but combining a "take" f...

The degradation of air quality by the release of volatile organic compounds (VOC) into the air particularly harms human health and our environment. Regulation of outdoor VOC emissions are required to prevent the formation of ground-level ozone, which is principally responsible for photochemical smog. Indoor emissions of VOC have been the subject of recent consideration from many governments around the world because of the adverse impact of VOC...

Water is not only an interesting object to be studied on its own, it also is an important component driving almost all ecological processes occurring in our landscapes. Plant growth depends on soil water content, as well is nutrient turnover by microbes. Water shapes the environment by erosion and sedimentation. Species occur or are lost depending on hydrological conditions, and many infectious diseases are water-borne. Modeling the comple...
