Setting an Agenda for the Social Studies of Nanotechnology by Hyungsub Choi, Sarah Kaplan, Cyrus C. M. Mody and Jody A. Roberts To foster greater collaboration between social scientists and stakeholders in the nanotechnology arena, the Wharton School and the Chemical Heritage Foundation presented a joint symposium to encourage debate about the most productive role of the social sciences in nanotechnology. Social scientists benefited from hearing various nanotechnology stakeholders discuss what research would be most helpful. Stakeholders, in turn, had the opportunity to consider what social scientists can offer in terms of understanding the evolution of technology, technology-in-use, and the economics of technical change, risk analysis, and communication.

The Hidden Danger of Static Electricity – A White Paper
Typical examples include liquids flowing through pipelines or filling into drums and tanks, powder dropping down a chute – even a person walking across an insulating floor. Static electricity is particularly hazardous in operations involving flammable solvents or other flammable, low-conductivity materials. A static spark in such hazardous locations can result in fires or actual explosions, causing property damage, lost production… even serious injuries or fatalities.

What is Yield Stress and Why does it Matter?
Some materials can better be described as soft solids than as fluids. Strong gels and thick pastes possess an inherent structure to such a degree that they will not flow appreciably unless left for a very long time. Many less obvious robust materials also possess such a structure, albeit more delicate. One property of
soft solids that will give us a more representation characterization is yield stress.
For example, open a new jar of mayonnaise and, without shaking or stirring; lay it on its side. If it hasn’t been disturbed recently it shouldn’t move noticeably over a period of a few minutes. It is safe to say that it has a very high viscosity but we can also say that under the gentle conditions here the mayonnaise is, in fact, exhibiting behavior more akin to a soft-solid than a thick liquid. Turn the jar upright again and carefully insert a large cooking spatula into it.
