Fondant icing sugar syrup, produced by processing fondant with invertase. Fondant fancies are a type of cake typically coated in poured fondant. "Rolled fondant," "fondant icing," or "pettinice," which is not the same material as poured fondant, is commonly used to decorate wedding cakes. Although wedding cakes are traditionally made with marzipan and royal icing, fondant is increasingly common due to nut allergies as it does not require almond meal. Rolled fondant includes gelatin (or agar in vegetarian recipes) and food-grade glycerine, which keeps the sugar pliable and creates a dough-like consistency. It can also be made using powdered sugar and melted
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
