➀ Researchers have synthesized carbon quantum dots (CQDs) from almond resin using a green and sustainable method; ➁ The CQDs exhibit strong optical properties and biocompatibility, making them potential candidates for bioimaging and drug delivery; ➂ The study highlights the importance of using natural precursors in nanomaterial synthesis for environmentally friendly practices.

➀ Researchers developed a reusable nanocomposite by modifying cobalt zinc ferrite (CZF) with carbon quantum dots (CQDs) to enhance photocatalytic activity under visible light. ➁ The CZF@CQDs nanocomposite was synthesized through a two-step process and exhibited approximately 95% degradation of Reactive Blue 22 within 25 minutes. ➂ The study highlights the potential of this nanocomposite in environmental remediation efforts, particularly in treating dye wastewater.
