Three-dimensional nanomaterials of desired structural/morphological properties and highly porous with a high specific surface area are important in variety applications. In this work, glycerol-mediated self-growth 3-D dandelion flower-like nickel chloride (NiCl2) from nickel-foam (NiF) is obtained for the first time using room-temperature (27 °C) processed wet chemical method electrocatalysis a...

Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of fo...

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. The pressure distribution directly affects its performance. So an investigation on the flow characteristics inside the annular foam breaker is important to optimize its structure. In this paper, the computational fluid dynamics (CFD) code, FLUENT, is employed to simulate the flow ...

Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

Materials. The PEDOT:PSS (Clevios PH 1000, 1 wt%) aqueous dispersion was purchased from Heraeus. Waterborne polyurethane (PU) was provided by DSM (China). Poly(dimethylsiloxane) (PDMS, Sylgard 184, Dow Corning) prepolymer was prepared by mixing base silicone gel with a curing agent in a 10:1 weight ratio. Dimethyl sulfoxide (DMSO) was purchased from Aladdin Chemistry Co., Ltd., Shanghai, China....
