Investigating the ball-milled calcined coal gangue on the hydration of limestone blended cement

Lei Xu

Calcined coal gangue (CCG) exhibits promising application potential in limestone-cement binary binders. However, the activity of CCG would possibly be weakened due to the particle agglomeration after calcination. In the present research, we tried to overco ...

ECO2 framework assessment of limestone powder concrete slabs and columns

Hisham Tarek Mohamed Hafez

Producing limestone powder requires comparably far less energy than the production of ordinary Portland cement (OPC), making it a promising sustainable solution for partial replacement of OPC in concrete. Lower production energy could be translated into lo ...

Does powder averaging remove dispersion bias in diffusion MRI diameter estimates within real 3D axonal architectures?

Marco Pizzolato

Noninvasive estimation of axon diameter with diffusion MRI holds the potential to investigate the dynamic properties of the brain network and pathology of neurodegenerative diseases. Recent studies use powder averaging to account for complex white matter a ...

Ultrafast carbothermal reduction of silica to silicon using a CO2 laser beam

Jaeki Jeong

We report the extraction of silicon via a carbothermal reduction process using a CO2 laser beam as a heat source. The surface of a mixture of silica and carbon black powder became brown after laser beam irradiation for a few tens of seconds, and clear peak ...

A high-performance compact electromagnetic actuator for a PMMA ball-valve micropump

Martinus Adela Maria Gijs, Christophe Yamahata, Meng Shen

We present the microfabrication and characterization of a reciprocating-type poly(methylmetacrylate) (PMMA) ball-valve micropump which is actuated with a high-performance and compact electromagnetic circuit of centimeter size. We have improved by finite el ...

Modélisation quantitative du procédé de frittage sélectif par laser : relation paramètres/microstructure

Cédric André

The Direct Metal Laser Sintering process (DMLS) is a Rapid Manufacturing (RM) technique. A 3D object is built layer by layer through laser consolidation of metallic powders. Several industrial DMLS stations are commercialised. The current performances of t ...
