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 کاملInfluence of Permethrin and Cypermethrin on Behavior in the Mouse
Permethrin and Cypermethrin are synthetic pyrethroids, belonging to a group of insecticides with low mammalian toxicity and high insecticidal activity. The present study evaluated sub-acute toxicity of dermally administrated permethrin and cypermethrin in mice. Behavioral examination included assessments of lethality, weight gain, grooming, analgesymetry, anxiety, grasping, motor activity, and ...
