Summary: This review article systematically introduces the applications of various fluorescence chemosensors in the fluorescence detection of organoarsenic feed additives. The sensors are classified and grouped according to their structures and functions, and a detailed report on the structure, photophysics, and fluorescence sensing properties of different chemosensors is provided. Finally, future prospects for the design and development of practically useful sensor systems for selectively and discriminatively detecting organoarsenic compounds are stated.

Summary: Organoarsenic compounds are commonly used feed additives, but their degradation produces toxic inorganic arsenic, causing severe soil and groundwater pollution. Therefore, it is necessary to develop methods for trace detection of organoarsenic additives in wastewater. Fluorescence-based sensing has become popular for detecting water and environmental contaminants, and various fluorescence chemosensors have been designed for the detection and quantification of organoarsenic additives in different environmental samples. This review discusses the recent developments in fluorescence-based chemosensing of organoarsenic feed additives. Future perspectives on the design of sensor systems for selective and discriminative sensing of organoarsenic compounds are also discussed.

Summary: A novel layered magnesium phosphate (MgP) was synthesized using an ionothermal approach. Adding the MgP to lithium grease resulted in superior lubrication compared to the typical lubricant MoS2. The crystal structure and resource endowment of layered materials were discussed to understand the lubrication mechanism. This finding could aid in the development of new high-efficiency solid lubricants.

Summary: Emerging and re-emerging zoonotic viral diseases, particularly enveloped viruses like SARS-CoV-2, have a significant impact on public health. The lipid composition of the viral envelope and changes in host cell lipid metabolism during viral infection provide an opportunity to understand how these viruses infect cells. In this study, the lipid composition of VeroE6-TMPRSS2 cells infected with SARS-CoV-2 was characterized, with a focus on the ceramide to sphingomyelin ratio. This lipid profile can help in the development of antiviral strategies and vaccines.

Summary: The study reveals significant differences in structure and mechanical properties between the furcation and collar regions of the periodontal ligament (PDL). The dense collar region is stiffer and acts as a scaffold for tooth stabilization, while the furcation region contains more proteins related to remodeling and load transfer, suggesting a critical role in these processes.

Summary: A novel TiO2 thin film was prepared on ceramic hollow fibers using sol-gel method with PVP and PVA as additives. The effects of different PVP and PVA contents on the properties of TiO2 sol and the performance of ultrafiltration membranes were thoroughly investigated. The membrane with 1.0 wt% PVP and 0.8 wt% PVA showed superior separation performance and antifouling properties.

Summary: Different extraction protocols were compared for extracting prolamins from kidney beans, showing that 70-80% ethanol concentrations and a two-step protocol were beneficial for higher protein content. Variations in protein subunits and properties were observed, with potential applications in food packaging materials due to the hydrophobic nature of kidney bean prolamins.

Summary: This study evaluated the effectiveness of a thermal-based model in predicting the rubber chemical composition of end-of-life vehicle tyres (EOLT)-derived crumb rubber. The thermal model successfully predicted the composition of EOLT-derived crumb rubber enabling rapid screening of such products to match engineering applications.

Summary: This study developed a GC-MS identification workflow for carbohydrate fragmentation compounds, built a library of compounds detected by five different GC-MS methods, investigated and compared compound coverage among the methods, and explored possible reaction pathways for some analytes. A total of 389 compounds were detected, with solid-phase microextraction detecting the highest number of analytes and derivatization GC-MS technique detecting the lowest but largest molecules.

Summary: The study aimed to explore the relationships between the molecular fine structure of starch and the composition of storage proteins and metabolic enzymes in chickpea seeds. Results showed that storage proteins and starch biosynthetic enzymes influence each other, with a positive correlation between amylopectin size and total protein content. Higher seed globulin content may indicate higher amylose content and more short-medium amylose chains. This research could aid in selecting chickpea varieties with desired qualities, such as low starch digestibility.
