Life Cycle Assessment of Sweet Sorghum as Feedstock for Second-generation Biofuel Production [PDF]

open access: yes, 2017
There exist few life cycle assessments (LCAs) in the literature that focus on the second-generation biofuel production from sweet sorghum, a non-food-source feedstock that offers several advantages in terms of farming requirements compared to corn or ...

MRI investigation of granular interface rheology using a new cylinder shear apparatus [PDF]

open access: yes, 2009
The rheology of granular materials near an interface is investigated through proton magnetic resonance imaging. A new cylinder shear apparatus has been inserted in the MRI device, which allows the control of the radial confining pressure exerted by the ...

Oxide dispersion strengthened nickel produced by nonreactive milling [PDF]

open access: yes
It is shown that oxide dispersion strengthened alloys can be produced by a postulated nonreactive milling mechanism whereby the dispersoid is trapped at the interface between welding metal powder particles. This interparticle welding is possible because,
