Low cost fabrication of continuous flow optofluidic microreactor for efficient dye degradation using graphene QDs@MOF (Ti) photocatalyst.

The optofluidic microreactor, a convergence of optics and microfluidics, offers advanced functionalities that can be pivotal in the rapid assessment of nanocatalysts for tackling environmental contamination issues. This article presents an efficient approach for degrading Methylene blue (MB) dye, commonly used in the textile industry, within a cost-effective polydimethylsiloxane (PDMS) based continuous flow optofluidic microreactor. This microreactor combines graphene quantum dots (QDs) and NH-MIL-125 (MOF(Ti)) as a highly effective photocatalyst coating within its microchannels.

Solar photocatalytic degradation of metformin by TiO synthesized using Calotropis gigantea leaf extract.

A novel TiO nanoparticle was prepared through green synthesis using Calotropis gigantea (CG) leaf extract. Morphological analysis showed dispersed spherical CG-TiO nanoparticles with an average size of 42 nm. The prepared catalyst was used for the degradation of metformin (a widely used diabetic medicine) by solar photocatalysis.

A Rare Case of Large Bowel Obstruction Secondary to Bone Grafting.

Anterior abdominal wall incisional hernias can occasionally present as acute intestinal obstruction. Incisional hernias occurring at uncommon sites or after uncommon surgeries may contribute to diagnostic dilemmas. Herein, we report the case of a 53-year-old lady who presented with obstructed incisional hernia following autologous iliac bone grafting.
