Understanding foams & foaming
Most of the common foams are a two-phase medium of gas and liquid with a particular structure consisting of gas pockets trapped in a network of thin liquid lms and plateau borders. Some well known foams are bubble baths, dishwater detergents and the foam head on beers. Many oils foam when trapped gas is suddenly released under conditions of an abrupt drop in pressure. In some re ners in which t...
متن کاملFoaming in Apple Wine
At Kiviks Musteri AB, situated in the southeast part of Scania, a wide variety of products based on fruits and berries, are produced. One of these products is base apple wine, which is used for the production of cider and mulled wine and also is sold to other producers of cider. A foaming problem has occurred at some customers when the cider is bottled, and this problem has been traced to the b...
متن کاملSeparation Using Foaming Techniques
Separation of various chemical components from each otheJO is often the most difficult step in analytical procedures. The problems attached to separation become further magnified when the species concentations are extremely low. A group of techniques that has proven useful especially in dilute solutions for separating and concentrating metallic as well as nonmetallic ions and complexes, protein...
متن کاملMembrane enhanced peptide synthesis.
This communication reports a new technology platform that advantageously combines organic solvent nanofiltration (a newly emerging technology capable of molecular separations in organic solvents) with solution phase peptide synthesis-Membrane Enhanced Peptide Synthesis (MEPS).
متن کاملEnhanced electrical conductivity in graphene-filled polycarbonate nanocomposites by microcellular foaming with sc-CO2
Electrically conductive polycarbonate foams containing a low concentration of graphene nanoplatelets (0.5 wt.%) were produced with variable range of expansion ratio by applying a high pressure batch foaming process using sc-CO2. The structure of the foams was assessed by means of SEM, AFM and WAXS, and the electrical conductivity was measured in the foam growing direction. Results showed that e...
