Application of Phanerochaete Chrysosporium on Biochemimechanical Pulping Process of Terentang Wood (Campnosperma Auriculata Hook.f) [PDF]

, 2016
Terentang wood (Campnosperma auriculata Hook.f) is relatively low in specific gravity (0.3), hence its utilization as pulp by chemi-mechanical is an alternative process.

Estimating the effective elastic modulus and specific fracture energy of snowpack layers from field experiments

Journal of Glaciology, 2016
Measurements of the mechanical properties of snow are essential for improving our understanding and the prediction of snow failure and hence avalanche release. We performed fracture mechanical experiments in which a crack was initiated by a saw in a weak

Flat Energy Bands within Antiphase and Twin Boundaries and at Open Edges in Topological Materials

, 2019
A model for two-dimensional electronic, photonic, and mechanical metamaterial systems is presented, which has flat one-dimensional zero-mode energy bands and stable localized states of a topological origin confined within twin boundaries, antiphase ...

Clues on black hole feedback from simulated and observed X-ray properties of elliptical galaxies [PDF]

, 2009
The centers of elliptical galaxies host supermassive black holes that significantly affect the surrounding interstellar medium through feedback resulting from the accretion process.

Specific Mechanical Energy and Thermal Degradation of Poly(lactic acid) and Poly(caprolactone)/Date Pits Composites

International Journal of Polymer Science, 2018
The compatibility of date pits (DP) with polylactic acid (PLA) or polycaprolactone (PCL) is investigated. Composites were prepared by compounding PLA or PCL with date pits at 10, 20, 30, and 40% wt/wt and extruded.

Role of the kinematics of probing electrons in electron energy-loss spectroscopy of solid surfaces

, 2015
Inelastic scattering of electrons incident on a solid surface is determined by the two properties: (i) electronic response of the target system and (ii) the detailed quantum-mechanical motion of the projectile electron inside and in the vicinity of the ...

Plasma activation mechanisms governed by specific energy input: Potential and perspectives

Plasma Processes and Polymers, 2023
AbstractIn a low‐temperature plasma, the electrons pick up energy from the electric field in collisions with atoms and molecules, gaining high kinetic energy that must be sufficient for ionizing reactions to sustain the plasma. For molecular gases, an average energy per heavy gas particle is thus available in the plasma, the specific energy input ...

The Impact of Mechanically-Imposed Shear on Clogging, Fouling and Energy Demand for an Immersed Membrane Bioreactor

Membranes, 2018
The impact of the application of mechanically-imposed shear on the propensity for fouling and clogging (or “sludging„—the agglomeration of sludge solids in the membrane channel) of an immersed flat sheet (iFS) membrane bioreactor (MBR ...
