Preparation of Cellulose Particles with a Hollow Structure

Langmuir, 2020
In this study, we report the preparation of hollow cellulose particles via a solvent-releasing method with the ionic liquid 1-ethyl-3-methylimidazolium acetate ([Emim]Ac). A dispersion comprising [Emim]Ac droplets with dissolved cellulose and a hexane medium containing a stabilizer was poured into a large amount of acetone (precipitant), resulting in ...

Fatigue of Metal Hollow Spheres Structures

Advanced Engineering Materials, 2008
A study was conducted to examine and formulate the effect of the microstructure of metal hollow spheres structures (MHSS) on their fatigue properties. Standard compression/compression fatigue tests were conducted to measure the macroscopic properties of microstructures with different structural parameters.

Structures of a hollow filamentary conical helix

Acta Crystallographica Section A Foundations of Crystallography, 2003
A hollow conical helix (HCH) of graphitic materials broadens the conical configuration by introduction of wrapping about 120 degrees symmetry positions in addition to the traditional rotation about 60 degrees symmetry sites. Complete structural models are established for a HCH and examined taking into account the rotation mode, coincidence site lattice

Ultralight Fractal Structures from Hollow Tubes

Physical Review Letters, 2012
A fractal design is shown to be highly efficient both as a load bearing structure and as a general metamaterial. Through changing the hierarchical order of the structure, the scaling of material required for stability against loading can be manipulated.

Production of hollow spheres (HS) and hollow sphere structures (HSS)

Materials Letters, 2009
In our paper we focus on component materials, production and prospective applications of metallic hollow spheres. We give an insight into technology, production, and the hollow spheres' diversity. It is our aim to provide an overview of the technology and enable the reader to evaluate whether the hollow spheres technology meets their specific needs.
