1Supporting IrO2 and IrRuOx nanoparticles on TiO2 and Nb-doped TiO2 nanotubes as electrocatalysts for the oxygen evolution reaction显示文摘IrO2 and IrRuOx(Ir:Ru 60:40 at%),supported by 50 wt%onto titania nanotubes(TNTs)and(3 at%Nb)Nb-doped titania nanotubes(Nb-TNTs),as electrocatalysts for the oxygen evolution reaction(OER),were synthesized and characterized by means of structural,surface analytical and electrochemical techniques.Nb doping of titania significantly increased the surface area of the support from 145(TNTs)to 260 m2g-1(Nb-TNTs),which was significantly higher than those of the Nb-doped titania supports previously reported in the literature.The surface analytical techniques showed good dispersion of the catalysts onto the supports.The X-ray photoelectron spectroscopy analyses showed that Nb was mainly in the form of Nb(IV)species,the suitable form to behave as a donor introducing free electrons to the conduction band of titania.The redox transitions of the cyclic voltammograms,in agreement with the XPS results,were found to be reversible.Despite the supported materials presented bigger crystallite sizes than the unsupported ones,the total number of active sites of the former was also higher due to their better catalyst dispersion.Considering the outer and the total charges of the cyclic voltammograms in the range 0.1–1.4 V,stability and electrode potentials at given current densities,the preferred catalyst was Ir O2 supported on the Nb-TNTs.The electrode potentials corresponding to given current densities were between the smallest ones given in the literature despite the small oxide loading used in this work and its Nb doping,thus making the Nb-TNTs-supported IrO2 catalyst a promising candidate for the OER.The good dispersion of IrO2,high specific surface area of the Nb-doped supports,accessibility of the electroactive centers,increased stability due to Nb doping and electron donor properties of the Nb(IV)oxide species were considered the main reasons for its good performance.Radostina V.Genova-Koleva Francisco Alcaide Garbine Alvarez Pere L.Cabot Hans-Jürgen Grande María V.Martínez-Huerta Oscar Miguel 2019Journal of Energy Chemistry2019,28,7:2

5Healthcare staff as promoters of parental presence at anesthetic induction:Net Promoter Score survey显示文摘BACKGROUND Surgical intervention is usually a traumatic event that causes stress and anxiety in the pediatric patient and the family environment.To reduce the harmful effects of presurgical anxiety,parental presence during induction of anesthesia(PPIA)is one of the more notable interventions used in medical centers.However,data on this measure are difficult to evaluate and often face resistance from healthcare staff.AIM To analyze the perception of the healthcare workers after the implementation of a PPIA program.METHODS A survey was developed and sent by email to all the healthcare staff working in the children’s area of a tertiary hospital.It consisted of 14 items divided into positive aspects of PPIA and negative aspects of PPIA evaluated with the use of a Likert scale(1 to 5).The demographics of the respondents were included in the data collected.The answers to the questions were interpreted through the Net Promoter Score(NPS).The statistical analysis compared the differences in the responses to each question of the survey made by the different groups of health personnel included.RESULTS A total of 141 surveys were sent out,with a response rate of 69%.Of the total number of responses,68%were from women and 32%from men.The average age of the participants was 42.3±10.6 years.As for the positive questions about the PPIA,83%had an NPS>50,and only one had a score between 0 and 50,which means that the quality of the service was rated as excellent or good by 100%of the respondents.On the other hand,100%of the negative questions about the PPIA had a negative NPS.Responses to the question“PPIA increases patient safety”were significantly different(P=0.037),with a lower percentage of pediatric surgeons(70%)thinking that PPIA increased patient safety,compared with anesthesiologists(90%),nursing(92%),and other medical personnel(96%).CONCLUSION The personnel who participated in the PPIA program at our center were in favor of implementation.There were no validated arguments to support worker resistance to the development of the PPIA.María Velayos Karla Estefanía María Alvarez María C Sarmiento Lucas Moratilla Pascual Sanabria Francisco Hernández Manuel V López Santamaría 2021World Journal of Clinical Pediatrics2021,10,6:1
