• alkaloid found in black pepper (Piper nigrum) and long pepper (Piper longum). It is responsible for the pungency of these spices and is known for its numerous therapeutic effects. PRN exhibits significant anti-inflammatory, antioxidant, antimicrobial, antitumor, and neuroprotective properties [150][151

• obtained by Vasimalai et al. using various spices, such as cinnamon, red chili, turmeric, and black pepper, for a simple hydrothermal method. They found that black pepper yields CDs with the highest QY up to 43.6% [62]. Vandarkuzhali et al. also obtained a very high quantum yield of 48% using pseudo-stem

• . This geometry change is most likely prompted by co-adoption of oxide spices on the platinum surface. In the IR spectra the absorption band at 1000 cm−1, which corresponds to the P–(OH)2 stretch vibration, decreases at higher potentials and indicates this symmetry change. So far all studies had been
