Herein, a new class of robust bicontinuous elastomer–metal foam composites with highly tunable mechanical stiffness is proposed, fabricated, characterized, and demonstrated. The smart composite network two foams, one metallic made low melting point alloy (LMPA) the other elastomeric polydimethylsiloxane (PDMS). can be tuned by inducing phase changes in its LMPA component. Below LMPA, Young's mo...

Metal hydride applications span a wide variety of tech! nologies\ e[g[\ energy conversion\ chemical compressors and hydrogen storage[ A knowledge of heat and mass transfer in a metal hydride reactor during the absorption and desorption of hydrogen is important for performance optimization of the reactor[ One of the key requirements in the design of metal hydride bed is the enhancement of the e}...

in many processes polymeric foams can be produced by using chemical or physical blowing agents. in this work for polyethylene foam production, the chemical blowing agents and compression moulding process were employed. at first, by using dsc diagram of two polyethylene grades, a suitable polyethylene grade was selected for foam production and then we discuss about blowing agent critical percent...
