This article investigated new macro-cellular carbons, called carbon meringues, formed by whipping an aqueous solution of tannin until liquid foam is obtained. Carbon meringues were fully investigated, and thermal conductivity ...Read More
Porous monoliths, often referred to as polymerised High Internal Phase Emulsions (polyHIPEs), are materials made of polymers that have applications ranging from chemical engineering to biomedicine. In this paper, a ...Read More
Carbon foams are novelty materials that have a wide range of applications such as radiators, thermal protection, and fire-resistant cores. The main carbon sources of carbon foams are sucrose, coal, ...Read More
This article discusses the creation and characterization of albumin based rigid and elastic foams. These foams were created using formaldehyde as the hardener for the protein, while camphor was used ...

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. ...Read More
The purpose of this study was to produce an environmentally friendly foam using tannins, that did not contain any formaldehyde or blowing agents. Two experimental tannin foams were compared to ...Read More
Rigid foams were prepared using quebracho tannins and their physical and thermal properties were determined experimentally. These properties were then compared to those of rigid foams derived from mimosa tannins ...
