ompanies can extract from a well. The unusual product is a biological detergent or surfactant, called a Pepfactant because it is made from peptides, the building blocks of proteins.
One of the possible applications that we are aware of is a surfactant that would switch between the wash cycle and rinse cycle during clothes washing, which would mean you could remove visible suds without having to use as large a quantity of water, said researcher Annette Dexter.
The unique aspect of the Pepfactant is that it can be switched on or switched off depending on its intended application. For example, in laundry detergents there is a built-in pH change that occurs between the wash and rinse cycles. Pepfactants that are designed to respond to that pH change could be added to the detergent to reduce the rinse time, Dexter noted.

Helping the carbon nanotube industry avoid mega-mistakes of the past
A new analysis of by-products discharged to the environment during production of carbon nanotubes (CNTs) expected to become the basis of multibillion-dollar industries in the 21st Century has identified cancer-causing compounds, air pollutants, and other substances of concern, researchers reported.
Desire L. Plata and colleagues described their work as totally new,? noting that past analyses of the environmental impact of the emerging nanomaterials industry have been based on the toxicity of ingredients used in the recipes, rather than the actual pollutants formed during CNT manufacture. While expressing concern about the possible health and environmental effects of
