Investigation of shear banding in three-dimensional foams [PDF]

open access: yes, 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

Modeling polycrystals with regular polyhedra

open access: yesMaterials 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.

Microplastics Increase Soil pH and Decrease Microbial Activities as a Function of Microplastic Shape, Polymer Type, and Exposure Time

open access: yesFrontiers 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 ...

An Evaluation of Non-Stochastic Lattice Structures Fabricated Via Electron Beam Melting [PDF]

open access: yes, 2006
Metal foam structures have many applications and can be used as structural supports, heat exchangers, shock absorbers, and implant materials. Stochastic metal foams having different cell sizes and densities have been commercially available for a number

Klein foams

open access: yesIndiana University Mathematics Journal, 2011
Klein foams are analogues of Riemann and Klein surfaces with one-dimensional singularities. We prove that the field of dianalytic functions on a Klein foam $Ω$ coincides with the field of dianalytic functions on a Klein surface $K_Ω$. We construct the moduli space of Klein foams and we prove that the set of classes of topologically equivalent Klein ...
