“…Another possible pathway is the dehydroxylation of gibbsite into anhydrous alumina (). [ 37,41,51 ] However, this could not be confirmed since no corresponding peaks were identified for anhydrous alumina in the powder XRD pattern. This could be due to either the alumina phase contributing towards the formation of sodium aluminium silicate carbonate hydrate or transforming to the amorphous phase:

Al {(OH)}_{3} \to {Al}_{2} O_{3} + H_{2} normalO

“…This section was attributed to three separate processes occurring within this temperature range: evaporation of free water within the range of 24°C to 150°C, [ 8–10 ] decomposition of goethite to hematite according to , [ 41,51–53 ] and dehydroxylation of gibbsite to boehmite at 150°C to 350°C according to .

“…The first mass loss section was observed in the range of 24 C to 350 C and resulted in a mass loss of 3.2%. This section was attributed to three separate processes occurring within this temperature range: evaporation of free water within the range of 24 C to 150 C, [8][9][10] decomposition of goethite to hematite according to reaction R3.1, [41,[51][52][53] and dehydroxylation of gibbsite to boehmite at 150 C to 350 C according to reaction R3.2.

“…Considering the phases identified in the XRD profile at 1000 C, this mass loss was attributed to the evaporation of the structural water existing in the hydrate salts and, at higher temperatures, to the decomposition of calcite to calcium oxide and CO 2 (R3.5). [41,[52][53][54][55][56][59][60][61][62] Another possibility is the reaction of calcium oxide with titanium and silicon oxides [41,51] : [52,62,63] Another change is the transformation of quartz to its polymorph beta-cristobalite [51,52] : Quartz ! β −Cristobalite ðR3:7Þ…”

An iron‐based catalyst from bauxite residue (aka BR and red mud) was developed for removing biomass gasification tar. Its performance was investigated with naphthalene as the model tar compound. This was achieved by measuring the catalytic naphthalene conversion at five space velocities and at four temperatures in the 500°C to 800°C range, both in a N2 environment and in 13 vol% H2 with the balance N2 for 14 hours to determine the long‐term performance. The physical and chemical characteristics of the catalyst were studied prior to and after exposure to naphthalene to track the evolution of the catalyst as a result of the chemical reaction. In addition, the effects of calcination temperature and reduction with H2 on the surface characteristics were investigated. The bauxite residue catalyst was shown to be significantly active for naphthalene cracking, with its activity comparable to that of an industrial Ni catalyst. Activity measurements over 14 hours of testing showed that the catalyst activity decreased from 98% to 65% naphthalene conversion with time as a result of catalyst deactivation when tested in a N2 reaction environment. In the presence of 13 vol% H2; however, the activity maintained >95% conversion for the entire duration of the experiment.

Rice root knot nematode, Meloidogyne graminicola is an important nematode pest with a devastating potential that causes serious damage to rice crop. There is an intensive search for eco-friendly, sustainable alternative to the existing nematode management practices. Host plant resistance offers propitious results in managing this minuscule crop enemy. Preliminary screening of 1731 Oryza sativa germplasms followed by periodic evaluation of nine resistant / tolerant germplasms shed new insights on nematode resistance. We observed seasonal inconsistency in the resistance in previously reported germplasms 'Ramakrishna', 'TKM6', 'Abhisek', 'Laxman sal', 'Ratna', and 'TKM1'. Hence, we strongly recommend repeated screening of identified resistant/tolerant rice germplasm lines against M. graminicola in both winter and summer season to confirm the consistency in resistance scale. Further investigation is needed to nullify other chance factors like nematode pathotypes.
