Materials Science and Engineering Initiative focuses on sustainability

Materials Science and Engineering Initiative focuses on sustainability: "Materials Science and Engineering Initiative focses on sustainability"

"UC Santa Cruz researchers are developing new materials for a wide range of devices and products, from solar cells to surfboards

"It sounds like something out of science fiction, but a magnetic skyrmion is a real thing, and skyrmion-based devices might someday dominate data storage and processing, combining high speed, low energy consumption, and small size.
UC Santa Cruz physicist David Lederman studies the materials needed to create and control skrymions, which are very stable, very small magnetic structures. He leads a team of scientists and engineers at three UC campuses and a national laboratory who are working to understand the fundamental physics of these structures while assessing the feasibility of using them in data storage and processing devices."
"Like the field of materials science in general, the project straddles the divide between basic and applied research. "There's a lot of fundamental science involved, but at the end of the day, you want to come up with something useful," Lederman said.
Materials science is also inherently interdisciplinary, he said, involving chemistry, physics, engineering, and even biology. Lederman directs the Materials Science and Engineering Initiative at UC Santa Cruz, which includes faculty in several departments in the Division of Physical and Biological Sciences and the Baskin School of Engineering."

Raising the standards_How nickel-containing stainless steel make food safer

How nickel-containing stainless steel make food safer

The FDA considered this Listeriosis outbreak to be “yet another reason to fully implement the Food Safety Modernization Act” (FSMA) which was signed into law on January 4, 2011. The Act aims to ensure the US food supply is safe by shifting the focus of federal regulators from responding to contamination to preventing it, and provides the FDA with the authority to require preventive controls across the food supply chain; perform inspections and ensure compliance; recall contaminated food and ensure imported foods meet US standards.

Are these standards met in the EU.? 
The arguements are well illustrated in the Ni-Institute News Letter under the following 3 paragraphe headed as follows:

The full letter may be consulted at the link beleow. 

Raising the standards:

"A fifth of all nickel production is destined for food contact materials, primarily stainless steel, which because of its outstanding properties meets the stringent requirements of the industry. To ensure that food is completely safe, standards and guidelines for equipment must be adhered to. Yet there are many different standards, by different organizations, in different countries, with different approaches, even if they have the same ultimate goal. Some standards are mandatory, others are voluntary, and they are regularly updated to address new concerns."

-Need for standards Explained.

-A stainless steel for every application.

-Not just clean and shiny.
