A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.

Cleaner and greener technologies for process and product selection and design have gained popularity in recent years. Life cycle assessment (LCA) is a systematic approach that enables selection of cleaner and greener products and processes. Recently, significant progress has been made for the use of LCA for product/process evaluation and selection, however, its use in process design and environ...

Cleaner technology is central to sustainable development. It has the potential, at least in some industries, to reduce environmental impacts whilst enabling economic growth. Indeed, cleaner technology can be seen as resource efficiency, enabling firms to become both cleaner and more competitive at the same time. In contrast, conventional ('end-of-pipe') treatment imposes costs on society which ...

Colombia is a remarkable coal producer and exporter worldwide; several sectors use this resource for electricity and thermal energy production. Among them, the ceramic industry consumed 118,590 tons in 2011. Most of the pottery production companies in this country are located effects to the population nearby. Despite of the importance of these industries to the small rural economies, the govern...

China's industry accounts for 46.8% of the national Gross Domestic Product (GDP) and plays an important strategic role in its economic growth. On the other hand, industrial wastewater is also the major source of water pollution. In order to examine the relationship between the underlying driving forces and various environmental indicators, values of two critical industrial wastewater pollutant ...

In this paper we report our study on the user experience of robot vacuum cleaner behaviour. How do people want to experience this new type of cleaning appliance? Interviews were conducted to elicit a desired robot vacuum cleaner personality. With this knowledge in mind, behaviour was designed for a future robot vacuum cleaner. A video prototype was used to evaluate how people experienced the be...

What are the mechanisms that prevent partners from cheating in potentially cooperative interactions between unrelated individuals? The cleaner fish Labroides dimidiatus and client reef fish both benefit from an interaction as long as the cleaner eats ectoparasites. However, the cleaner fish prefers some client mucus, which constitutes cheating. Field observations suggested that clients control ...

Signals transmit information to receivers about sender attributes, increase the fitness of both parties, and are selected for in cooperative interactions between species to reduce conflict [1, 2]. Marine cleaning interactions are known for stereotyped behaviors [3-6] that likely serve as signals. For example, "dancing" and "tactile dancing" in cleaner fish may serve to advertise cleaning servic...
