Metal leaf Metal leaf A metal leaf, also called composition leaf or schlagmetal, is a thin foil used for decoration. Metal leaves can come in many different shades. Some metal leaves may look like gold leaf but does not contain any real gold. This type of metal leaf is often referred to as imitation leaf. Metal leaves are usually made of gold (including many alloys), silver, copper, aluminium, brass (sometimes called "Dutch metal" typically 85% Copper and 15% zinc) or palladium, sometimes also platinum. Vark is a type of silver leaf used for decoration in Indian cuisine. Goldbeating, the technique of producing
High entropy alloys High entropy alloys High-entropy alloys (HEAs) are substances that are constructed with equal or nearly equal quantities of five or more metals. These alloys are currently the focus of significant attention in materials science and engineering because they have potentially desirable properties. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. For example, additional elements can be added to iron to improve its properties, thereby creating an iron based alloy. Hence, high entropy alloys are a novel material. Furthermore, research indicates that some HEAs have considerably better
