AbstractFoam‐mat drying is an alternative dehydration technique to tray, drum, freeze, and spray drying. Foam‐mat drying can be used to obtain high‐quality powders from fruit juices and other heat‐sensitive food products which are difficult to dry using traditional drying techniques. In foam‐mat drying, the product to be dried is first converted into a

Effects of foaming parameters on sized-foam properties
Textile Research Journal, 2016Foaming parameters are the foundations of foam-sizing technology. The impacts of foaming parameters, including temperature, agitator speed, quality fraction of the foaming agent, size recipe and concentration, on foam properties are remarkable. Aiming at optimizing the foaming parameters, foam height, foaming ratio, foam half-life and foam viscosity ...

β-Lactoglobulin aggregates in foam films: Correlation between foam films and foaming properties
Journal of Colloid and Interface Science, 2009Single foam films made from aqueous protein solutions containing aggregates have been studied using a thin film balance apparatus. When the solutions are free from non-aggregated proteins, the films are either fluid or gelified, depending on the aggregate size.

On How Surfactant Depletion during Foam Generation Influences Foam Properties
Langmuir, 2012Although it is known that foaming a surfactant solution results in a depletion of the surfactant in the bulk phase, this effect is often overlooked and has never been quantified. Therefore, the influence of surfactant depletion on foam properties using solutions of the two nonionic surfactants, n-dodecyl-β-D-maltoside (β-C(12)G(2)) and ...

Polyvinylcarbazole foams. II. Properties
Journal of Applied Polymer Science, 1966AbstractThe uniformity, heat and solvent resistance, and thermal conductivity of foamed polyvinylcarbazole have been examined. Compressive and tensile properties, dielectric constant, and loss factor have been determined between ambient temperature and the softening range.

Acoustic Properties Of Reticulated Plastic Foams
Journal of Sound and Vibration, 1994Abstract Some general aspects of sound propagation in rigid porous media are discussed, particularly with reference to the use of a single—dimensionless—frequency parameter and the role of this, in the light of the possibility of varying gas properties, is examined.

Elastic Properties of Nanoparticle Monolayer Foams
The Journal of Physical Chemistry B, 2012Monolayers of nanosized carboxylate-functionalized polystyrene particles at the air/water interface assemble into two coexisting liquid phases of different densities. The rheological properties of the individual phases and of the resulting nanoparticle texture is measured using a magnetic needle microrheometer. We show that, despite the liquid behavior

Properties of protective loose‐fill foams
Journal of Applied Polymer Science, 1998This study compared the performance of eight commercial starch and expanded polystyrene (EPS)-based loose-fill foam products. Density of starch-based foams is higher, by a factor of two to three times, than either EPS-based ones. Compressive stress of most starch-based foams did not differ significantly from 0.0893 MPa value for virgin EPS foam.

Electric conductance is the only electric property of liquid foams for which experimental data are available. Apparently no one has measured yet their dielectric constants, the dependence of this constant on bubble dimensions, and so forth. First, the electric conductance of single films is reviewed.

The properties of foams and lattices
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005Man and nature both exploit the remarkable properties of cellular solids, by which we mean foams, meshes and microlattices. To the non-scientist, their image is that of soft, compliant, things: cushions, packaging and padding. To the food scientist they are familiar as bread, cake and desserts of the best kind: meringue, mousse and sponge. To those who
