Thermal stabilization of alumina modified by lanthanum
Transition alumina, with different La loadings, were synthesized from boehmite (AlOOH) hydrosols containing a PEO/PPO/PEO triblock copolymer (Pluronics P123) and lanthanum nitrate. After calcination at 500 °C, the xerogels prepared from these sols have large specific surface area ( 400 m/g) and very large porous volumes, increasing with the amount of La to reach 2.5 cm/g for La/(La + Al) = 0.03...

متن کاملThermal expansion of doped lanthanum gallates
Thermal expansion of several compositions of Sr and Mg-doped LaGaO3 including an A-site deficient composition (La0⋅9Sr0⋅1)0⋅98(Ga0⋅8Mg0⋅2)O2⋅821 were measured in the temperature range from 298 to 1273 K. The effect of doping on thermal expansion was studied by varying the composition at one site of the perovskite structure (either A or B), while keeping the composition at the other site invaria...
متن کاملThermal Stabilization of an Endoglucanase by Cyclization
An intein-driven protein splicing approach allowed for the covalent linkage between the N- and C-termini of a polypeptide chain to create circular variants of the endo-β-1,3-1,4-glucanase, LicA, from Bacillus licheniformis. Two circular variants, LicA-C1 and LicA-C2, which have connecting loops of 20 and 14 amino acids, respectively, showed catalytic activities that are approximately two and th...
