Materials containing 2–20 wt% zirconia supported on γ-alumina were prepared by multiple step incipient wetness impregnation with solutions of zirconium acetylacetonate in benzene. The materials were calcined at 823 K and were characterised by X-ray diffraction, XPS, DRS in the UV-visible region and FTIR in the regions of OH stretching and skeletal vibrations of adsorbed pyridine. The results demonstrated that the zirconium is present as isolated species at the surface and in the bulk of a mixed ...

Metakaolin is obtained by dehydroxylation of kaolin; its dealumination is carried out with sulfuric acid. 29Si MAS NMR studies show that a three-dimensional framework of SiO4 is formed with an increase in kaolin calcination temperature. On the other hand, 27Al MAS NMR shows that calcination temperatures up to 850°C bring on a decrease of the hexa-coordinated aluminum nuclei, while tetra- and penta-coordinated aluminum nuclei are being formed. In the range of temperatures studied, the amount of Brönsted ...

Catalysts containing from 8 to 28% wt. of niobia supported on γ-alumina by impregnation with niobium pentaethoxide solutions were characterized by infrared spectroscopy of adsorbed pyridine as a probe for acidic sites and CO2 adsorption as a probe for basic sites. The catalysts had their activity measured in isopropanol dehydration at 453 K, 1-butene isomerization at 348 K and in cumene dealkylation at 728 K. The density and strength of the Lewis acid sites and of the basic sites decreased with ...

The thermal spreading of MoO3 onto silica was studied in comparison with the thermal spreading onto alumina using different characterization techniques. X-ray diffraction results showed that MoO3 crystals were transformed into Mo amorphous species on alumina and silica supports by thermal treatment. Laser Raman spectroscopy results also evidenced the transformation of MoO3 bulk into small Mo clusters and/or dispersed Mo species, which are highly distorted, interacting with alumina and silica supports. ...

Ultrastable Y zeolites with different degrees of steaming severity were further acid leached. They were characterized by multiple quantum magic angle spinning (MQMAS) NMR and infrared spectroscopy, examining the hydroxyl regions as well as the ring vibration region of probe molecules (pyridine and 2,6 dimethyl-pyridine (2,6-lutidine)). The isotropic chemical shifts of the aluminum species observed through 2D MQMAS technique when compared with the 1D MAS spectra showed unambiguously that the peak in ...

FTIR has been used to investigate structural and acidic modification carried out upon calcination of La-, Nd-, Sm-, Gd- and Dy-exchanged NaY zeolite. The introduction of RE cations brought about no significant changes in the structural region of the zeolites. However, in the hydroxyl region, a band ranging from 3530 to 3498 cm−1 may be observed. This band was attributed to OH groups interacting with RE cations and the position thereof is shifted to higher wavenumbers as the ionic radius of the cations ...

Leprosy is a chronic infectious disease caused by Mycobacterium leprae, which affects mainly the skin and peripherical nerves. Brasil has not yet achieved its goal of elimination of the number of cases of this disease, ranking second in terms of absolute numbers worldwide, with India occupying the first position. Primary Neural Leprosy is considered to be a challenge in diagnosis, since it affects the peripherical nerve system with the absence of skin lesions, thus mimicking rheumatological disorders, ...

The effects of different stocking rates and ratios of red tilapia (Oreochromis spp) in combination with snook (C. undecimalis) were evaluated in 0.01 ha ponds. Initially, six ponds were stocked with red tilapia fingerlings at 22,500 fish/m2 and reared for two months. After this period, three different batches of 3.6 and 9 snooks were introduced into three of these ponds with one replicate. The ponds were fertilized with chicken litter and tilapia fed with commercial food at 1% body weight daily. ...
