Boron arsenide is a chemical compound of boron and arsenic. It occurs in cubic sphalerite, and it can be alloyed with gallium arsenide. It also occurs as an icosahedral boride.
Cadmium telluride is a crystalline compound formed from cadmium and tellurium. It is sandwiched with calcium sulfide to form a p-n junction photovoltaic solar cell.
Boron nitride is a chemical compound having chemical formula BN comprising equal numbers of nitrogen and boron atoms. BN exists in a number of crystalline forms and is isoelectronic to a similarly structured carbon lattice.
Graphene was first identified in 2004 and for the last few years has been the focus of much scientific research.
Natural honeycomb structures occur in many different environments. Based on these, man-made honeycomb structures have been built with similar geometry to allow the reduction of the quantity of material used, and thereby realizing minimal weight and material cost.
Gallium arsenide is a type III/V semiconductor, with high electron mobility and a high saturated electron velocity compared to silicon,.
Metal foam is a cellular structure made up of a solid metal containing a large volume fraction of gas-filled pores. These pores can either be sealed (closed-cell foam), or they can be an interconnected network (open-cell foam).
Composite materials have been used in the marine industry for various applications including gratings, ducts, shafts, piping, hull shells, etc for several decades.
