CeO-Supported Single-Atom Cu Catalysts Modified with Fe for RWGS Reaction: Deciphering the Role of Fe in the Reaction Mechanism by In Situ/Operando Spectroscopic Techniques.

Reverse water-gas shift (RWGS) reaction has attracted much attention as a potential approach for CO valorization via the production of synthesis gas, especially over Fe-modified supported Cu catalysts on CeO. However, most studies have focused solely on investigating the RWGS reaction over catalysts with high Cu and Fe loadings, thus leading to an increase in the complexity of the catalytic system and, hence, preventing the gain of any reliable information about the nature of the active sites and reaction mechanism. In this work, a CeO-supported single-atom Cu catalyst modified with iron was synthesized and evaluated for the RWGS reaction.

Comparison of some hematological parameters between male and female patients infected with COVID-19.

Background: COVID-19 is a highly contagious virus that is rapidly spreading across the world. As the number of COVID-19 patients is quickly rising, and certain nations and areas, such as the third world countries, lack the medical resources, it is critical to track and monitor a patient's status using blood parameters on regular testing. The aim of this study is to compare the serum D-dimer levels, Ferritin, CRP, WBCs, Lymphocytes, and Neutrophils in male and female patients infected with COVID-19.

Oxygen vacancies in Ru/TiO - drivers of low-temperature CO methanation assessed by multimodal operando spectroscopy.

Hydrogenation of CO is very attractive for transforming this greenhouse gas into valuable high energy density compounds. In this work, we developed a highly active and stable Ru/TiO catalyst for CO methanation prepared by a solgel method that revealed much higher activity in methanation of CO (ca. 4-14 times higher turnover frequencies at 140-210°C) than state-of-the-art Ru/TiO catalysts and a control sample prepared by wetness impregnation.
