Article Synopsis
- Co-based metal-organic frameworks (MOFs) are effective electrocatalysts for the two-electron oxygen reduction reaction (2e ORR) used in hydrogen peroxide (H₂O₂) production, but typically face activity-selectivity challenges.
- The study introduces a ZnCo bimetal-triazole framework (ZnCo-MTF) that enhances 2e ORR efficiency through improved Co activation via 1,2,3-triazole coordination, allowing better adsorption and reduction of oxygen molecules.
- ZnCo-MTF demonstrates impressive performance metrics with nearly 100% selectivity for the 2e ORR, an onset potential of 0.614 V, and a hydrogen peroxide production rate of 5
Fungi and bacteria afflict humans with innumerous pathogen-related infections and ailments. Most of the commonly employed microbicidal agents target commensal and pathogenic microorganisms without discrimination. To distinguish and fight the pathogenic species out of the microflora, novel antimicrobials have been developed that selectively target specific bacteria and fungi.

Objective: To explore the role of cardiopulmonary bypass (CPB) with vacuum assisted venous drainage(VAVD)in the management of newborns with congenital heart diseases.
Methods: Total 15 newborns with congenital heart diseases (11 males and 4 females)underwent heart operations. Their age ranged from 2 days to 28 days [mean:(15.
Periodic mesoporous organosilicas (PMOs) with controlled structures have been synthesized by using cetyltrimethylammonium bromide (CTAB) and sodium perfluorooctanoate (PFONa) as co-templates, 1,2-bis (triethoxysilyl)ethane (BTEE) as an organosilica precursor. By increasing the weight ratio of PFONa/CTAB, a structure transformation from a cubic (Pm-3n) to a two-dimensional hexagonal (p6m) mesostructure and then to multilamellar vesicles can be observed. The cubic and hexagonal samples have similar particle size (200-750 nm), pore size (2.
