Skin symbiotic bacteria on amphibians can play a role in protecting their host against pathogens. Chytridiomycosis, the disease caused by Batrachochytrium dendrobatidis, Bd, has caused dramatic population declines and extinctions of amphibians worldwide. Anti-Bd bacteria from amphibian skin have been cultured, and skin bacterial communities have been described through 16S rRNA gene amplicon seq...

Molecular sieve catalysts containing transition metals have been attracting attention for their potential applications in various fields, including environmental and industrial catalysis. A Cu-Ce-Zr/SAPO-34 series of molecular were prepared by the impregnation method, effect Zr introduction on selective catalytic reduction NO Cu-Ce/SAPO-34 was explored. Through characterization methods, physica...

Hydrocarbon species trapped in the catalyst that work as the reaction center and govern the conversion and product selectivity of chloromethane transformation were revealed by a very efficient home-made ultra-short contact time pulse reaction system over pre-coked SAPO-34.

This communication reports the discovery of several small-pore Cu-zeolites and zeotypes that produce methanol from methane and water vapor, and produce more methanol per copper atom than Cu-ZSM-5 and Cu-mordenite. The new materials include Cu-SSZ-13, Cu-SSZ-16, Cu-SSZ-39, and Cu-SAPO-34.

SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. hydroisomerization activity (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane base oil. All experiments were achieved at fixed bed plug flow reactor temperature...

Neste trabalho, vou me dedicar a três tópicos relacionados entre si: 1) importância da Linguística Moderna no processo de ensino e aprendizagem leitura escrita; 2) alguns comentários especiais sobre política educacional em geral elaboração dos currículos escolares; 3) informações respeito do projeto alfabetização, chamado O Pulo Sapo. Dos tópicos, o que recebe mais destaque é Sapo, um alfabetiz...

X-/Q-band electron paramagnetic resonance (EPR) and hyperfine sublevel correlation (HYSCORE) spectroscopies have been employed, in conjunction with density functional theory (DFT) modeling, to determine the location of Cr5+ions SAPO-5 zeotype materials. The interaction unpaired Cr5+ species 27Al could be resolved, allowing for first detailed structural analysis ions SAPO interpretation experime...

Silicoaluminophosphates SAPO-5 and SAPO-11 were synthesized using the hydrothermal method, 170 ºC with triethylamine dipropylamine as structure directing agents, respectively. This work aimed incorporation of boron into structures obtained by modifying composition system, a reaction equation: Al2O3:P2O5:x SiO2: yB2O3:1,5TEA (or DPA):50H2O, x, y=0-0.2. The phase was identified XRD characterized ...
