Partial Oxidation of Bio-methane over Nickel Supported on MgO-ZrO Solid Solutions.

Syngas can be produced from biomethane via Partial Oxidation of Methane (POM), being an attractive route since it is ecofriendly and sustainable. In this work, catalysts of Ni supported on MgO-ZrO solid solutions, prepared by a one-step polymerization method, were characterized by HRTEM/EDX, XRD, XPS, H-TPR, and in situ XRD. All catalysts, including Ni/ZrO and Ni/MgO as reference, were tested for POM (CH:O molar ratio 2, 750 ºC, 1 atm).

Alkaline Modification of -Coffee and -Cocoa Agroindustrial Waste for Effective Removal of Pb(II) from Aqueous Solutions.

Arabica-coffee and Theobroma-cocoa agroindustrial wastes were treated with NaOH and characterized to efficiently remove Pb(II) from the aqueous media. The maximum Pb(II) adsorption capacities, qmax, of Arabica-coffee (WCAM) and Theobroma-cocoa (WCTM) biosorbents (qmax = 303.0 and 223.

Cross Species Analysis and Comparison of Tumors in Dogs and Cats, by Age, Sex, Topography and Main Morphologies. Data from Vet-OncoNet.

The animal cancer burden is essential for the translational value of companion animals in comparative oncology. The present work aims to describe, analyze, and compare frequencies and associations of tumors in dogs and cats based on the Animal Cancer Registry created by Vet-OncoNet. With 9079 registries, regarding 2019 and 2020, 81% ( = 7355) belonged to dogs.
