Some recipes call for cream, non-fat milk solids, flour, or meringue powder. There are two types of meringue-based buttercream: Italian and Swiss. The meringues must be cooled to room temperature in order not to melt
Metal foam titanium foams are common for their tensile strength, corrosion resistance and biocompatibility. The back legs of Siberian Husky named Triumph received foam metal prostheses. Mammalian studies showed that porous metals, such as titanium foam, may allow vascularization within the porous area. Orthopedic device manufacturers use foam construction or metal foam coatings to achieve desired levels of osseointegration. The primary functions of metallic foams in vehicles are to increase sound damping, reduce weight, increase energy absorption in case of crashes, and (in military applications) to combat the concussive force of IEDs. As an example, foam filled tubes could be used as
