The effect of adding Sn to Pt/CeO2–Al2O3 and Pt/Al2O3 catalysts was studied with X-ray photoelectron spectroscopy (XPS), 119Sn Mössbauer
spectroscopy, and adsorption microcalorimetry of CO at room temperature. Catalysts were reduced in situ at 473 (non-SMSI state) and 773 K

In this article I intend to highlight some of the main ideas in Paton’s ideology in order to understand what made him an outstanding person in the white minority during the apartheid period; it is also intended to highlight what…

A new analytical approximate expression for the period of the simple pendulum is obtained by using a heuristic but pedagogical derivation. This formula depends on two parameters obtained by comparing term-by-term the power-series expansions of the approximate and exact expressions…

We tracked the daily movements of three juvenile golden eagles (Aquila chrysaetos) using satellite telemetry. Straight distances covered in an hour and throughout a day were calculated. Daily movements of golden eagles are mostly characterized by short-distance excursions, with 64%…

Nowadays, deploying service robots and adapting their services to a new environment is a task which might require several days. This is an important problem of robotics in general, but specially when the goal is to bring robots to our…

Background: Lipocalin-2 (Lcn2) a newer adipocyte-secreted acute phase protein was recently reported to be correlated with potential effects in obesity and inflammation. The reactions of this protein in progressive exercise have not yet been evaluated. Purpose: This study was designed…

Despite its frequent use, there is little understanding of the concept of differential
among upper high school and undergraduate students of physics. As a first step to identify the origin of this situation and to revert it, we have done…
