Insights into Redox Dynamics of Vanadium Species Impregnated in Layered Siliceous Zeolitic Structures during Methanol Oxidation Reactions
(2020-01-08)
Supported transition metal catalysts have been extensively applied to oxidative and reductive processes. The understanding of surface speciation and active site-support interactions in these materials play a substantial ...
Day and night in the subterranean: measuring daily activity patterns of subterranean rodents (Ctenomys aff. knighti) using bio-logging
(Oxford University Press, 2019-09)
While most studies of the impacts of climate change have investigated shifts in the spatial distribution of organisms, temporal shifts in the time of activity is another important adjustment made by animals in a changing ...
The thrombocyte aggregation process in the turtle Phrynopys hilarii (Chelonia). An ultrastructural study
(2002-07-01)
This study investigates the thrombocyte aggregation process in the South American fresh water turtle (Phrynopys hilarii) using electron microscopy. Blood was taken from surgically exposed lateral neck vessels often turtles ...

Cobalt Supported on Zirconia. Selective Catalytic Reduction of NO Using Propane as Reducing Agent.
(Betham Science, 2014-11)
The catalytic behavior of a series of cobalt catalysts supported on zirconia in the selective catalytic reduction(SCR) of NO has been studied using propane as reducing agent. The catalysts were characterized by Raman ...
Behavior of bimetallic PtSn/Al2O3 catalysts prepared by controlled surface reactions in the selective dehydrogenation of butane
(Elsevier Science, 2009-03)
The "one-pot" circulation reactor system was used for the modification of Pt/Al2O3 catalyst using Controlled Surface Reactions (CSRs) with the involvement of tetraethyltin. At 40 °C the tin anchoring reaction resulted in ...
Role of tyrosol on Candida albicans, Candida glabrata and Streptococcus mutans biofilms developed on different surfaces
(2017-02-01)
Purpose: To assess the effect of tyrosol on the production of hydrolytic enzymes (by Candida biofilm cells) and acid (by Streptococcus mutans biofilms), as well as to quantify single and mixed biofilms of these species ...
