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...

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...

This paper discusses the innovative application of interwoven fiberglass mesh (FM) to strengthen lightweight foamed concrete (LFC).

Foamed concrete is a special type of and it can be used widely in construction reinforced structures. this study very helpful for understanding about foamed mechanical properties concrete. Lot researches are going on material finally we got It has lot advantages compared to conventional Fluidity Flowability good the foam low cost high Manufacturing Production poly urethane simple easy. because ...

In our previous study, a precursor of porous aluminum consisting uniform alloy was foamed by frictional heating during friction stir processing. It found that the temperature at tool gradually increased as traversed owing to heat stored in steel plate. this welding lower-foaming-temperature ADC12 (Al-Si-Cu) and higher-foaming-temperature A6061 (Al-MgSi) processing shown placing first-half regio...
