This present study was undertaken to investigate the ultrasonic delignification of switchgrass (Panicum virgatum L.) and effects irradiation on molecular microstructure switchgrass. We investigated this question using response surface methodology (RSM) featuring a four-factor, three-level Box–Behnken experimental design with acoustic power (120, 180, 240 W), solid–solvent ratio (1/25, 1/20, 1/1...

Transversal applications of 3D-printing (or Additive Manufacturing) have been recently implemented in the field Geomechanics. In a process, printed volume is obtained from successive layering adjacent soil filaments. this work, fabric an as-printed has carried out by combining Mercury Intrusion Porosimetry (MIP) tests and Scanning Electron Microscope (SEM) observations, with aim to highlight ho...
