An improved strain-transfer model was developed for surface-bonded sapphire-derived fiber Bragg grating sensors. In the model, the core and cladding of the fiber are separated into individual layers, unlike in conventional treatment that regards the fibe...

In aluminium production, anode effects occur when the alumina content in the bath is so low that normal fused salt electrolysis cannot be maintained. This is followed by a rapid increase of pot voltage from about 4.3 V to values in the range from 10 to 8...

In this study, a method was suggested to produce dried powder from red mud (RM) sludge with 40%?60% water content without heating. The RM sludge is discharged from the Bayer process, which is used to produce alumina from bauxite ores. Nonthermally treate...

Synthesis of MTBE on dealuminated and leaching Beta zeolites is provided. Hydrothermal and chemical dealumination of HBeta zeolite leads to less active catalysts due to a decrease in the total concentration of Brönsted acid sites. Furthermore, it has bee...
