SOME ENGINEERING PROPERTIES OF PEA SHELLS [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2008
Drying of biomass is important to assure a year round supply of a certain feedstock and to minimize the loss of organic matter during storage. Egypt produces about 0.15 million ton of pea shells annually that can be used for the production of biofuel ...

Effect of Gravity on the Scale of Compliant Shells

Biomimetics, 2020
Thin shells are found across scales ranging from biological blood cells to engineered large-span roof structures. The engineering design of thin shells used as mechanisms has occasionally been inspired by biomimetic concept generators.

Texture of the Freshwater Shells from the Unionidae Family Collected in the Czech Republic Investigated by X-ray and Neutron Diffraction

Crystals, 2021
Bivalve shells exhibit extreme mechanical resistance despite using a minimal amount of material. The shells thus represent an inspiration and a source of information for environmental, geological, and engineering sciences.
