Catalytic reduction of NO with CO at a lower temperature is an extremely challenging task, thus requiring conceivable surfaces to overcome such issues. Ru-substituted CeO catalysts prepared via the solution combustion method were employed in CO oxidation and NO-CO conversion studies. The characterization for material formation and surface structure was carried out through XRD, SEM, TEM, and BET surface area.

Recently, tuning catalytic material has gained huge importance for enhancing the catalytic performance of reactions. The present work describes the influence of aluminum in copper-manganese composite oxide with respect to the NO-CO redox reaction. The Al fabricated composite oxide showed the highest conversion in a lower temperature window.

The purpose of this study was to evaluate the reliability, sensitivity, specificity, and outcomes of surgical exploration, and the impact on free-flap survival of the venous anastomotic flow coupler for microvascular head and neck reconstruction in a consecutive series of patients. This is a retrospective review of consecutive patients treated in the department of oral and maxillofacial surgery who underwent reconstruction of a head and neck defect using venous anastomosis with a flow coupler-vascularised free flap between October 2015 and December 2020.

In the present study, designing of the catalyst was carried out using specific transition metals to boost the simultaneous NO-CO conversion reaction catalytically. These metal oxide systems have been prepared using the combustion and wet impregnation method.
