Researchers propose reason for capacity loss in metal-oxide battery materials

Green Car Congress

Magnetite, among other conversion-type electrode materials (i.e., In the following charge, this conversion reaction is not completely reversible—residues of metallic iron and lithium oxide remain. Because the conversion reaction is not fully reversible, these residual products accumulate.

Wireless Worries Overshadow Triumphs of RF Research

Cars That Think

IEEE Spectrum carried out its conversation with Foster by email to find out more about why RF exposure assessment research has been such a success, what makes RF dosimetry so difficult, and why public worries about health and wireless radiation never seem to go away. Foster: Measuring RF fields in free space is not a problem.

NYU Researchers Paving New Path for Robotics

Cars That Think

This is a sponsored article brought to you by NYU Tandon School of Engineering. New York University’s. From the very first day of joining NYU, we started a conversation about how we can collaborate on different aspects of this new initiative. Creating a shared physical hub leads to a convolution of what we do.

Researchers visualize lithiation of magnetite electrode in real time; hunting for new Li-ion electrode materials

Green Car Congress

A team of scientists from the US Department of Energy’s (DOE) Brookhaven National Laboratory, the University of Pennsylvania, and the University of Maryland, College Park, has developed an electron microscopy technique to visualize—in real time and at high resolution—lithiation pathways in electrode materials.
