Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

Systematic experimental study of the physico-chemical factors controlling the foaming and defoaming performance of several Pluronic nonionic block copolymers is performed in solutions of sodium caseinate. Dynamic light scattering measurements and microscopic observations confirm that a significant defoaming is observed above the cloud point of the nonionics, which is almost independent on the p...

We were able to produce the first ever meltderived bioactive glass scaffold that met the requirement of an ideal bone scaffold by using the gel-cast foaming process and a new glass composition. However, initially a small fraction of sodium potassium sulfate crystals formed during processing. The purpose of this work was to study and prohibit the growth of those crystals, which was the result of...

An easy method that combined gel casting and physical foaming was used to fabricate modified carbon foams. The design of carbon foams from sucrose/polyacrylamide hydrogel is a new concept for controlling the microstructure and improving the compressive properties of carbon foams. This article provides the micrographs obtained from optical and scanning electron microscope for foaming solution an...

A novel electro-thermal laminated ceramic composed of ceramic tile, carbon-based layer, dielectric layer, and foaming ceramic layer was designed and prepared by tape casting. The surface temperature achieved at an applied voltage of 10 V by the laminated ceramics was 40.3 °C when the thickness of carbon-based suspension was 1.0 mm and the adhesive strength between ceramic tile and carbon-based ...

The objective of this research was to evaluate new types of surfactants based on renewable materials (sugar and protein-based surfactants) for use in ink removal from recycled paper via flotation deinking. By applying green chemistry approaches we aim to minimize the environmental impact of deinking agents and also to open an avenue for a number of products that are to be generated from the uti...
