Physical Review Letters, 2003 We investigate the mechanical response of an aqueous foam, and its relation to the microscopic rearrangement dynamics of the bubble-packing structure. At rest, even though the foam is coarsening, the rheology is demonstrated to be linear. Under flow, shear-induced rearrangements compete with coarsening-induced rearrangements.

The Effect of Hydrogen Peroxide and Sodium Laureth Sulfate Concentration on the Mechanical Properties of Foamed Geopolymers [PDF]
Archives of Metallurgy and MaterialsTo achieve the need for sustainable development and integration of a circular economy in the production of products with porous structures, the need for removing high-temperature stages and raw material consumption has increased extensively.

Catalytic chemical vapor deposition synthesis of single- and double-walled carbon nanotubes from α-(Al1−xFex)2O3 powders and self-supported foams [PDF]
, 2009 An investigation of the potential interest of α-alumina–hematite foams, as opposed to powders, as starting materials for the synthesis of carbon nanotubes (CNTs) by catalytic chemical vapor deposition method was performed.

Operator Spin Foam Models [PDF]
, 2010 The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as the main tool.

Modeling polycrystals with regular polyhedra
Materials Research, 2006 Polycrystalline structure is of paramount importance to materials science and engineering. It provides an important example of a space-filling irregular network structure that also occurs in foams as well as in certain biological tissues.

Frontiers in Environmental Science, 2021 Microplastic pollution is a topic of increasing concern, especially since this issue was first addressed in soils. Results have so far been variable in terms of effects, suggesting that there is substantial context-dependency in microplastic effects in ...

Sl(N) link homology using foams and the Kapustin-Li formula [PDF]
, 2007 We use foams to give a topological construction of a rational link homology categorifying the slN link invariant, for N>3. To evaluate closed foams we use the Kapustin-Li formula adapted to foams by Khovanov and Rozansky.

Investigation of shear banding in three-dimensional foams [PDF]
, 2010 We study the steady flow properties of different three-dimensional aqueous foams in a wide gap Couette geometry. From local velocity measurements through Magnetic Resonance Imaging techniques and from viscosity bifurcation experiments, we find that these
