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

Detection and monitoring prostate specific antigen using nanotechnology approaches to biosensing

Grant Perry, Fernando Cortezon-Tamarit, Sofia I. Pascu

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 4-18 doi: 10.1007/s11705-019-1846-8

Abstract: Prostate cancer has a high incidence in men and remains the second cause of mortality due to cancer. As the development of the disease is greatly correlated to age, the identification of novel detection methods reliable, efficient, and cost effective is a matter of significant importance in the ageing population of western societies. The detection of the prostate specific antigen (PSA) in blood samples has been the preferred method for the detection and monitoring of prostate cancer over the past decades. Despite the indications against its use in massive population screening, PSA still remains the best studied biomarker for prostate cancer and the detection of its different forms and incorporation in multiplexed designs with other biomarkers still remains a highly valuable indicator in the theranostics of prostate cancer. The latest developments in the use of nanomaterials towards the construction of PSA biosensors are reviewed hereby. The incorporation of gold nanoparticles, silica nanoparticles and graphene nanostructures to biosensing devices has represented a big leap forward in terms of sensitivity, stability and miniaturization. Both electrochemical and optical detection methods will be reviewed herein for the detection of PSA.
