On the Use of Carbon Cables from Plastic Solvent Combinations of Polystyrene and Toluene in Carbon Nanotube Synthesis

open access: yesNanomaterials, 2021
For every three people on the planet, there are approximately two Tonnes (Te) of plastic waste. We show that carbon recovery from polystyrene (PS) plastic is enhanced by the coaddition of solvents to grow carbon nanotubes (CNTs) by liquid injection ...

Mechanical work performed by individual limbs of transfemoral amputees during step-to-step transitions: Effect of walking velocity [PDF]

open access: yes, 2014
The greater metabolic demand during the gait of people with a transfemoral amputation limits their autonomy and walking velocity. Major modifications of the kinematic and kinetic patterns of transfemoral amputee gait quantified using gait analysis may ...

How should we assess the mechanical properties of lower-limb prosthesis technology used in elite sport?: An initial investigation [PDF]

open access: yes, 2013
Despite recent controversy, it is not yet formally recognised how lower-limb prosthesis should be assessed for their performance. To assist in this process, experiments are undertaken to investigate the linearity, stiffness and assessment of feet based ...
