Surface Structure Dependent Activation of Hydrogen over Metal Oxides during Syngas Conversion.

Despite the extensive studies on the adsorption and activation of hydrogen over metal oxides, it remains a challenge to investigate the structure-dependent activation of hydrogen and its selectivity mechanism in hydrogenation reactions. Herein we take spinel and solid solution MnGaO with a similar bulk chemical composition and study the hydrogen activation mechanism and reactivity in syngas conversion. The results show that MnGaO-Solid Solution (MnGaO-SS) is a typical Mn-doped hexagonal close-packed (HCP) GaO with a Ga-rich surface.

Effectiveness of Standardized Nursing Terminologies for Nursing Practice and Healthcare Outcomes: A Systematic Review.

Purpose: This review evaluates the effectiveness of using standardized terminologies in nursing.

Methods: A systematic literature review was performed via PubMed, Web of Science, CINAHL, and OVID databases for articles published between January 1973 and September 2020. The Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies was used to assess the quality of all included studies.
