Fragmentation of molecular cations formed by electron-impact ionization is governed primarily by the redistribution of internal energy deposited during the collision event. A detailed understanding of how this energy drives the transition from bound vibrational motion to irreversible bond cleavage is essential for interpreting energy-resolved fragm...

Artificial intelligence (AI), especially generative artificial intelligence (GAI), is quickly changing education, work, and everyday life. Slovenia is an interesting example for studying these changes because it has adopted GAI very rapidly and there is already a growing number of empirical studies on its social and organisational impacts. This pa...

Sweet cherry pits, a significant fraction of agro-industrial bio-waste, are often underutilized despite their richness in bioactive compounds. In line with sustainable resource management and circular economy principles, their valorization using green extraction techniques has gained attention. Microwave-assisted extraction (MAE) and ultrasound-ass...

Nicotine is a naturally occurring bicyclic alkaloid, composed of a pyridine ring connected to a pyrrolidine ring. Possessing two heterocyclic nitrogen atoms, it behaves like a dibasic compound in water. The pyrrolidine nitrogen has a pKa of approximately 8.0 while the pyridine nitrogen has a pKa of 3.12-3.41. Therefore, at physiological pH of 7.4 a...
