An X-ray crystallographic study demonstrated that the tris complex of Al3+ with 2-methyl-8-quinolinol (Hmq), [Al(mq)3], had a discrete octahedral geometry in a meridional configuration with respect to mq-; the Al-N bonds were appreciably elongated. In organic solvents, the complex reacted with water to give a lower species of a mu-oxo dimer, [Al2O(mq)4], and a protonated ligand, depending on th...

Partículas de sílica dopadas com o complexo quercetina-Al foram preparadas através da hidrólise e condensação do tetraetilortossilicato (TEOS) utilizando catálise ácida e básica. A catálise ácida resultou em partículas com diâmetro em torno de 200 nm. A catálise básica com TEOS foi executada sobre um sol de alumina dopado com quercetina utilizado como precursor caroço e com este procedimento fo...

The thermal expansion coefficient of Al3Sc and Al3(Sc0:75X0:25), where X is Ti, Y, Zr or Hf, was measured by dilatometry between 25 and 1000 C. The measured value, ð16 1Þ 10 6 K , is constant between 25 and 900 C and insensitive to alloying element. Good agreement is found with a literature value determined from first-principle cal-

background: gnathostoma spinigerum causes larva migran in human which is endemic in southeast asia. information regarding larva migration is limited. in this study, we investigated the parasite migra­tion by recovery of worms from the whole body of mouse after oral infection with advanced third stage larvae (al3). the percentage of blood eosinophils was examined in parallel. methods: mice were ...

The primary phase of the Earth’s lower mantle, (Al, Fe)-bearing bridgmanite, transitions to post-perovskite (PPv) at deep mantle conditions. Despite extensive experimental and ab initio investigations, there are still important aspects this transformation that need clarification. Here, we address transition in (Al3+, Fe3+)-, (Al3+)-, (Fe2+)-, (Fe3+)-bearing bridgmanite using calculations valida...

As a cyan-emitting oxonitridosilicate phosphor, BaSi2O2N2:Eu2+ can be used as competent cyan compensator to improve the color rendering index of white light-emitting diodes (WLEDs). However, low luminescence efficiency and poor thermal stability this type phosphor seriously suppress its actual application in full-spectrum lighting. The replacements Ba2+ by Lu3+ Ba2+-Si4+ Lu3+-Al3+ greatly incre...

This paper has not been submitted elsewhere in identical or similar form, nor will it be during the first three months after its submission to Hydrobiologia Abstract The intercalibration (IC) exercise is a key element in the implementation of the Water Framework Directive (WFD) in Europe. Its focus lies on the harmonization of national classification methods to guarantee a common understanding ...
