    Critical Impact of Graphene Functionalization for Transition Metal Oxide/Graphene Hybrids on Oxygen Reduction Reaction

    Transition metal oxides (TMOs) anchored on a carbon nanostructure have been widely pursued for oxygen reduction reaction (ORR) catalysis. The high ORR activity of TMO/graphene has been often attributed to the synergistic nature between TMO and carbon but with little relevant mechanistic study. In this report, the focus is made on how the type of majority oxygen-containing functional group of graphene affects the ORR performance of the resulting TMO/graphene nanocomposites. Our TiO<sub>2</sub>/carboxylated graphene and ZrO<sub>2</sub>/hydroxylated graphene rendered an ORR activity very close to that of Pt/C with an equal mass loading, via a four-electron transfer dominant process unlike other TMO/graphene variants of study. It is revealed that a stable anchoring of nanoparticles (NPs) on the graphene surface, which is essential to prevent the restacking of graphene layers, is established only through a specific type of functional groups on the graphene. In addition, the interplay among TMOs, graphene, and functional groups is found to be deterministic in the activity and electron transfer pathway of ORR, which is supported by density function theory (DFT) calculations. The calculations indicate that the electron transfer pathway is dependent upon the structure of NPs interfacing with functional groups of the graphene as it affects the preferred sites for oxygen dissociation

Design, setting and participants This was a crosssectional, nationwide survey conducted in Brazil and Venezuela from February 2006 to June 2007 to obtain information about glycaemic control and its determinants in patients with diabetes mellitus attending outpatient clinics. Main outcome measures Haemoglobin A1c (HbA1c) level was measured by liquid chromatography, and patients with HbA1c ≥7.0% (53 mmol/mol) were considered to have inadequate glycaemic control. The association of selected variables with glycaemic control was analysed by multivariate linear regression, using HbA1c as the dependent variable. Results A total of 9418 patients with T2D were enrolled in Brazil (n=5692) and in Venezuela (n=3726). They included 6214 (66%) women and 3204 (34%) men. On average, HbA1c levels in women were 0.13 (95% CI 0.03 to 0.24; p=0.015) higher than in men, after adjusting for age, marital status, education, race, country, body mass index, duration of disease, complications, type of healthcare, adherence to diet, adherence to treatment and previous measurement of HbA1c. Sex modified the effect of some factors associated with glycaemic control in patients with T2D in our study, but had no noteworthy effect in others. Conclusions Women with T2D had worse glycaemic control than men. Possible causes for poorer glycaemic control in women compared with men include differences in glucose homeostasis, treatment response and psychological factors. In addition, sex modified factors associated with glycaemic control, suggesting the need to develop specific treatment guidelines for men and women
