"Failed states, conflict, technology - both in terms of the ability to use materials and the ability to learn about how materials are used - contribute to our concern about that as a threat, including what we know about what terrorists may have previously planned to do and may be planning to do," she said.
Superconductivity, which was discovered early in the 20th century, was a baffling phenomenon that seemed to defy conventional wisdom about how materials should behave.
In the context of chemistry learning, Ebenezer and Erickson (1996) used a phenomenographic approach to describe high school students' conceptions about solubility and discovered that students inappropriately apply knowledge about how materials behave at the macroscopic level to the microscopic level.
"Printed Page Beats PC Screen for Reading, Study Finds" (Aug. 10), about how material is comprehended more readily on the printed page than on the computer screen, omits one significant consideration.
Struck by how differently African objects were encountered in display cabinets in the UK with how they were actively used in festivals back home, she began to think about how material culture could be preserved and presented in a way that was more in keeping with local traditions.
In our fourteenth episode, we talk about how Material Design was built, how to create your own design language within your company, and why strong culture plays a critical role in the design process.
For most drug products, practical reasons dictate that the majority of studies to obtain knowledge about how material attributes and process parameters impact the CQAs of the drug product will be performed at a scale significantly smaller than commercial.
We discuss the dilemma of students wanting to share information in a mixed social network in order to remain popular, while also being wary about how material shared will make them appear.
"The kind of properties we're talking about are the kind of battery voltages possible with compounds, the mobility of ions and electrons in materials, chemical stability, safety, also indications about how the materials might be made," he says.
Another potential drawback that arises when using protein-based (or any polymer) materials is the lack of knowledge about how the materials will react to bacteria in their environment.
Although it is well documented that the materials comprising artificial structures influence the composition of organisms that use them as habitat, little is known about how these materials may chemically react with changing seawater conditions, and what effects this will have on associated biota.
