The rechargeable metal-air battery technology is a well-interested smart method for eco-friendly and sustainable energy storage. Both of the two order magnitude lower global market price per tonne Zn compared to lithium multiple theoretical practical specific density ZAB worldwide Li-ion designs contributes developing continuously Zn-air battery. air electrode as cathode has vital role in incre...

We have developed a new class of bistable Pickering foams, which can remain intact for weeks at room temperature but can be destroyed rapidly and on-demand with the use of a magnetic field. Such responsive foam systems can find application in various industrial and environmental processes that require controlled defoaming. These foams are stabilized by particles of hypromellose phthalate (HP-55...

Coffee beverage known as espresso, must be topped by a velvety thick, reddish-brown foam called crema, to be considered properly prepared and to be appreciated by connoisseurs. In spite of the relevant role played by crema as a quality marker, espresso coffee foam has not yet been the subject of detailed investigations. Only recently, some aspects of the Physics and Chemistry behind the espress...

In the Niger Delta, low oil recovery rates less than 30% results mainly due to production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, remaining becomes a good candidate for EOR methods CO2 injection, polymer foam in-situ combustion steam injection. But it stands, practice of these known enhanced is scarce in Nigeria’s Oil Gas industry. However, this project...

This paper introduces a new real-time air pollution alert system using mobile devices. Through the location awareness capability of mobile devices, Androidand iOS-based apps are developed to inform the public residing in the vicinity of air pollution areas. The apps have shown to be working successfully sending push notifications as well as a regional map to convey the air pollution information...

Finite element analysis, of regular Kelvin foam models with all the material in uniform-thickness faces, was used to predict the compressive impact response of low-density closed-cell polyethylene and polystyrene foams. Cell air compression was analysed, treating cells as surface-based fluid cavities. For a typical 1 mm cell size and 50 s impact strain rate, the elastic buckling of cell faces, ...

Residents living near a polyurethane foam manufacturing facility expressed concern to health officials over chemical emissions from the plant. Environmental monitoring of ambient air near the plant indicated the presence of toluene diisocyanate (TDI), which was used in foam production. Health officials collected blood samples from 113 residents and analyzed the blood sera for antibodies to TDI ...

the main factor affecting the economics of foam-assisted water alternative gas (fawag) process isthe loss of foaming agent by adsorption onto reservoir rocks. in this study, the effects of phases,surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density wereinvestigated by special adsorption experiments. moreover, a series of fawag tests were performedto examin...
