Biodegradable, superhydrophobic walnut wood membrane for the separation of oil/water mixtures

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 9,   Pages 1377-1386 doi: 10.1007/s11705-022-2157-z

Abstract: Freeze-drying of wood after lignin removal yields wood aerogels, which can be used as substrates to prepareA study using cross-sections of pristine wood chips as substrates retains the original strength of wood, but the use of the cross-sectional of wood pieces limits their thickness, strength, and size.The tensile strength results show that superhydrophobic films with pristine or activated wood substratesmaintained the strength of pristine wood and were 2.2 times stronger than the wood aerogel substrate

Gripping mechanisms in current wood harvesting machines

D. GOUBET, J. C. FAUROUX, G. GOGU

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 42-61 doi: 10.1007/s11465-013-0358-3

Abstract:

This paper focuses on the structural synthesis of gripping mechanisms used in the mechanization of the harvesting process. The importance of the gripping function in current devices like harvesting heads is underlined. This function is performed with several typical mechanisms which are listed and described in this article. This study distinguishes two kinds of planar gripping mechanisms mainly used in opening and closing the rollers: five concentric and two lateral ones. Both kinds have advantages and drawbacks. So a third kind of hybrid mechanism has been designed in order to orientate the axis of the rollers during gripping motion in order to combine concentric and lateral gripping advantages. Two planar and one spatial existing mechanisms are described. The last part of this paper presents a structural synthesis of such a spatial parallel mechanism by using the structural parameters and the general formulae established by the third author. Nine kinematic diagrams of spatial parallel mechanisms are provided.

Keywords： structural synthesis     parallel mechanisms     gripping mechanisms     wood harvesting     harvesting head
