Nicholas Lodge and other equipment for the home economics department. Lodge traveled to the United States in the 1980s to demonstrate at the International Cake Exploration Societé (ICES) convention. At the time, most American cakes were covered with thick buttercream icing. Many of the students in Lodge's classes had never seen the techniques he was using to decorate cakes with royal icing and rolled fondant. Feeling like the cake decorating field had become saturated in England, Lodge decided to move to the United States and teach classes on cake decorating. During a two-week class in Atlanta, Georgia, he decided to make the
Graphene foam A physically flexible battery was created using the foam for electrodes. The anode was made by coating the foam with a lithium-titanium compound () and the cathode by coating the foam with . Both electrodes were lightweight and their large surface area provided high energy density of 110 Wh/kg, comparable to commercial batteries. Power density was much greater than a typical battery. At a rate that completely discharged the material in 18 seconds, power delivered was 80 percent of what it produced during an hour-long discharge. Performance remained stable through 500 charge/discharge cycles. In 2017 researchers used carbon nanotubes to
