In this study, we propose a novel ion formation simulation method for electrospray ionization (ESI) and atmosphere pressure interface (API). In this method, not the sheer particle trajectory, but the evolution of droplets and the offspring of gaseous ions are introduced instead. For the first time, the dynamic droplet-to-ion transformation process in the API of ESI-MS is visualized. The results suggest that this model provides a better understanding of the ion evolution mechanism and we propose a way for mass spectrometer structure optimization and ion source parameter adjustment in new aspects.

Metal ions are essential for all life. In microbial cells, potassium (K) is the most abundant cation and plays a key role in maintaining osmotic balance. Magnesium (Mg) is the dominant divalent cation and is required for nucleic acid structure and as an enzyme cofactor.

Mitochondria, commonly referred to as "energy factories"of cells, play a crucial role in the function and survival of cardiomyocytes. However, as research on cardiac fibrosis has advanced, mitochondrial dysfunction(including changes in energy metabolism, calcium ion imbalance, increased oxidative stress, and apoptosis)is now recognized as a significant pathophysiological pathway involved in cardiac remodeling and progression, which also negatively affects the function and structure of the heart. In recent years, research focusing on targeting mitochondria has gained significant attention, offering new approaches for treating cardiac fibrosis.

Within the coral reef habitat, members of the Symbiodiniaceae family stand as pivotal symbionts for reef-building corals. However, the physiological response of Symbiodiniaceae on microplastics are still poorly understood. Research conducted in this investigation assessed the harmful impact of polystyrene microparticles (PS-MPs) on Cladocopium goreaui, a Symbiodiniaceae species with a broad distribution.

Bacterial nanocellulose (BNC) has attracted considerable attention in the field of biomedical engineering due to its potential for use in bone regeneration applications. The present study investigates the in vitro and in vivo efficacy of bacterial nanocellulose (BNC) combined with calcium and cerium ions (BNC-Ce:CaP) in bone regeneration applications. XRD analysis confirmed the presence of monetite and hydroxyapatite phases in BNC-CaP, while BNC-Ce:CaP revealed an additional brushite phase.
