Recovery and recycling of silica fabric from waste printed circuit boards to develop epoxy composite for electrical and thermal insulation applications.

Printed Circuit Boards (PCBs), a primary component of electronic waste (E-waste), contain silica fabric as a major non-metallic material, which needs to be reutilized for high-performance applications. This study focuses on the separation and recovery of silica fabrics through pyrolysis and their subsequent use in developing silica fabric-epoxy composites (SFR). Extracted silica fabric was characterized through FTIR, XRD, XPS, and SEM for morphology analysis.

Photophysical behavior of meso-N-butylcarbazole-substituted BODIPY in different nano-scale organized media.

The present work focuses on the photophysical behavior of meso-N-butylcarbazole-substituted BODIPY (CBZ-BDP) in different organized media towards exploring the possible use of the dye as a molecular sensor and imaging agent. The molecule shows an appreciable change in absorption and emission spectra at 75% water-acetonitrile mixture compared to pure acetonitrile. In water-acetonitrile mixture, it displays aggregate-induced emission (AIE) bands.
