This article reviews the state of the art in the field of porous amorphous metals by describing current processing techniques, mechanical properties, and potential applications. In addition to the reduction in density, the main benefit of introducing porosity in amorphous metals is the improvement in compressive ductility and energy absorption. This ductilizing effect is explained by: (1) shear...

Successful matrix acidizing for extremely thick carbonate reservoirs with long horizontal well sections and strong heterogeneity requires efficient temporary plugging diverting of acid fluid, ensuring fluid distribution to each production layer. Foamed-viscoelastic-surfactant (Foamed-VES) combines the benefits both foam viscoelastic surfactant (VES) acid, integrating viscous plugging. It can ac...

intercalation of lithium into ag-cnts sample is reported here. we have used a nano-porous silver foam as a frame for deposition of the cnts   inside   the   pores   by   electrophoresis   deposition   (epd) technique. by using  chronopotentiometry method,  we  have noticed that the li storage capacity of the prepared ag-cnts electrode was improved  noticeably  in  comparison  with  literature. ...

Foam fractionation is a process that has potential for application in the separation of proteins from aqueous solution because the molecules adsorb to the foam bubbles. However, some proteins are known to denature by unfolding upon adsorption to a gasliquid interface and, since the utility of unfolded proteins in pharmaceutical applications is low, it is possible that the use of foam fractionat...

Major limitations of calcium phosphate cements (CPCs) are their relatively slow degradation rate and the lack of macropores allowing the ingrowth of bone tissue. The development of self-setting cement foams has been proposed as a suitable strategy to overcome these limitations. In previous work we developed a gelatine-based hydroxyapatite foam (G-foam), which exhibited good injectability and co...

A new type of bioreactor for air pollution control has been developed. The new process relies on an organic-phase emulsion and actively growing pollutant-degrading microorganisms, made into a foam with the air being treated. This new reactor is referred to as a foamed emulsion bioreactor (FEBR). As there is no packing in the reactor, the FEBR is not subject to clogging. Mathematical modeling of...

Abstract Foamed rubber with a mixed cellular microstructure is compressible material used for various sealing applications in the automotive industry. For technical optimization, sufficiently precise model required. Here description porous elastic and viscoelastic response of low density foamed proposed adapted to ethylene propylene diene monomer (EPDM)-based rubber. The based on spherical shel...
