Production of’renewable Methane’has attracted renewed research interest as a fundamental probe reaction and process for CO_(2)utilization through potential use in Cl fuel production and even for future space exploration ***_(2)methanation is a structure sensitive reaction on Ni/CeO_(2)*** precisely elucidate the size effect of the Ni metal center on the CO_(2)methanation performance,we prepared2%Ni/CeO_(2)catalysts with pre-synthesized uniform Ni particles(2,4 and 8 nm)on a high surface area CeO_(2)*** electron microscopy(TEM)and ambient pressure X-ray photo spectroscopy(AP-XPS)characterization have confirmed that the catalyst structure and chemical state was uniform and stable under reaction *** 8 nm sized catalyst showed superior methanation selectivity over the 4 and 2 nm counterparts,and the methanation activity in term of TOF is 10 times and 70 times higher than for the 4 and 2 nm counterparts,*** DRIFTS studies revealed that the larger Ni(8 nm particles)over CeO_(2)efficiently facilitated the hydrogenation of the surface formate intermediates,which is proposed as the rate determining step accounting for the excellent CO_(2)methanation performance.

Nurses’perceptions about neonatal intensive care units providing family-centered care are associated with skin-to-skin contact implementation

Pediatric Investigation 2024年第1期8卷 61-65页

作者： Marilyn Aita Gwenaëlle De clifford-Faugère Geneviève Laporte Sébastien Colson Nancy Feeley Faculty of Nursing Universitéde MontréalMontrealCanada CHU Sainte-Justine Research Centre MontrealCanada Quebec Network on Nursing Intervention Research MontrealCanada Faculty of Medical and Paramedical Sciences CEReSSAix-Marseille UniversitéMarseilleFrance Ingram School of Nursing McGill UniversityMontrealCanada Centre for Nursing Research and Lady Davis Institute Jewish General HospitalMontrealCanada

Skin-to-skin contact(SSC)consists of positioning the diaper-clad infant against the parent’s chest and is considered a nursing practice rooted in family-centered care(FCC).1 SSC implies simultaneous parental presence and helps to facilitate their involvement from the earliest hours of their preterm infants’lives as this intervention is delivered by parents.1 FCC has gained worldwide popularity in recent years to promote parental presence and active participation of parents in care during neonatal intensive care units(NICUs)hospitalization.2 Both practices relate to developmental care(DC),which regroups specific interventions aimed at reducing stress and improving infant neurological development.
