A Long and Productive Life On his 96th birthday today, John Goodenough and his research team’s latest findings are the subject of much speculation.  He, fellow scientist Maria Braga, and his research team have created a battery claimed to be three times as energy dense as existing lithium-ion contemporaries, but exhibiting the counterintuitive property of improving with repeated charging cycles. Goodenough’s career began in 1943 (a year after your editor was born) with the award of his bachelor’s degree in mathematics from Yale University, followed his master’s and Ph.D. in physics from the University of Chicago in 1951 and 1952 respectively.  He worked at MIT and in 1976, left to become head of Oxford University’s Inorganic Chemistry Laboratory from 1976 …

Glass Like Metal, Plastic Like Steel

 Two very different materials forming techniques using materials that seem to defy their “normal” characteristics promise lighter, stronger, more efficiently manufactured products – with potential applications for green flight.  Dr. Seeley shared this item from Science Daily, regarding the potential use for this new material in the solar highways reported here.  One critique of that design is the need to maintain structural integrity with semi-trucks passing over a layer of glass through which everything from lane markers to warning messages could be displayed.  Jan Schroers, a materials scientist at Yale University, is experimenting with a new class of materials called bulk metallic glasses (BMG), or metal allows with randomly arranged atoms.  “Normal” metals have more well-ordered crystalline structures, but the …
