CO(2) can be used to separate surfactant and organic solvent completely in various surfactant/solvent solutions without contaminating the surfactants and solvents. We believe that the simple, efficient, and greener method has wide applications.

The natural composition of terrestrial ecosystems can be shaped by climate to take advantage of local environmental conditions. Ecosystem functioning (e.g., interaction between photosynthesis and temperature) can also acclimate to different climatological states. The combination of these two factors thus determines ecological– climate interactions.Aglobal empiricalmap of the sensitivity of vege...

This article explores the adequacy of international governance mechanisms to address environmental issues. It examines the impact of increased global economic integration on national and regional environmental standards, the role of market mechanisms in facilitating the dissemination of environmental standards from greener nations to less green ones and the impact of international agreements on...

A single clean, good-yielding, environment-friendly microwave-assisted procedure for O-silylation of uridine with tert-butyldimethylsilyl chloride (TBDMSCl), 1,8-Diazabicyclo(5.4.0)undec-7-ene (DBU) and potassium nitrate as catalyst under solvent-free conditions is reported. Subsequent silyl ether deprotection accomplished a reusable acidic resin via microwave irradiation. Both the silylation d...

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...

The in situ generated μ-oxo-bridged reactive hypervalent iodine(iii) species 1 or their analogues are introduced as more efficient organocatalysts for the catalytic strategy for realizing practical and greener oxidations.

A method developed for the screening of diethylene glycol (DEG) in toothpaste was released by the FDA in 2007. This method could not only quantify the DEG but also confirm if any potential interfering peak is present. However, disadvantages of this method such as intermittent shortages of the key reagent acetonitrile and the shorter than expected column-life issues have prompted a search for al...

The current circumstances on a worldwide level urgently impose to exploit technology in order to reduce environmental pollution, CO2. emissions and waste. The current technologies and the provisioned evolution steps take into consideration these facts and contribute to achieve greener footprint. This paper describes technologies as important elements in the design of Energy-aware Future Network...

Adopting “greener” manufacturing technologies is one means of reducing facility environmental impacts. To justify such capital investment, more informative environmental impact assessments are needed to determine their effects on the local environment. Since conventional life cycle assessment methods and manufacturing process models ignore consideration of space, time, and local environmental u...
