Summary: This study reports on the ion-trap mass spectrometry investigation of methanol-catalyzed proton transfer in para-aminobenzoic acid. The results suggest that single-solvent catalyzed intramolecular proton transfer is possible and must be considered during the late stages of electrospray ionization to predict the protonation site(s) and ion stability in the presence of solvent molecules.

Summary: A characteristic fragmentation pattern was observed for PUFAs containing allylic vicinal diol maresin 2), which were derivatized with N,N-dimethylethylenediamine (DMED), in positive-ion ESI-MS/MS. The presence of an allylic hydroxyl group distal to the DMED moiety resulted in aldehyde formation, while an allylic hydroxyl group proximal to the DMED moiety led to allylic carbene generation. These specific fragmentation pathways could be utilized for the identification of these PUFAs.

Summary: This study investigated the characteristic volatile compounds across the fermentation process of Dongbei Suancai (DS) using HS-GC-IMS combined with PCA, identifying 19 representative flavor substances in the samples. Differences in volatiles between naturally and inoculated-fermented DS at different fermentation stages were detected, with notable changes in flavor profile observed as fermentation progressed, particularly with the addition of Lactobacillus Plantarum as a starter culture. The combination of HS-GC-IMS and PCA proved to be an effective tool for analyzing the characteristic volatiles in DS samples, showing potential for identification and classification of DS flavor.

Summary: The study on the protonated cyclic dipeptide cyclo histidine-phenylalanine reveals that stereochemical factors have a significant impact on the collision-induced dissociation processes, primarily due to proton mobility and the formation of different intermediate cyclic structures. This contrasts with the minor stereochemical effects observed for other cyclic dipeptides where the proton is carried by an amide CO.

Summary: In this study, a lumped electrical characteristic model is developed for lithium-ion batteries with strong working condition characterization capability. An adaptive forgetting factor recursive least squares-linearized particle swarm optimization algorithm is proposed for accurate modeling and efficient parameter identification. Experimental results show that the proposed algorithm significantly reduces voltage tracking error and improves parameter identification accuracy.

Summary: Biodegradable plastic mulches (BDMs) have the potential to be an eco-friendly alternative to conventional plastic mulches in agriculture. However, their long-term impacts on soil ecosystems are still uncertain, and further research is needed. Incorporating BDMs into the soil may stimulate microbial activity, but there is also a risk of incomplete degradation and release of residual microplastics and additives.

Summary: Carbon nanomaterials (CNMs) have excellent capabilities in terms of adsorption, enhanced oxidation, and photocatalysis, attracting widespread attention in different fields. Metal-organic frameworks (MOFs) have been widely used due to their regular network structure, porous nature, and large specific surface area. However, the instability of MOFs in aqueous solutions limits their applications in chemical sensing. Recent studies have focused on increasing the stability of MOFs in water-based matrices through chemical modifications using CNMs.
