“…In the late stages of crystallization (30−40 min), the CSD curve's changing trend reverses. 4 The stirring speed does not change the micro mechanism of crystal nucleation and growth, but mainly affects the crystal by changing the flow characteristics of the system. With the increase of stirring speed, the crystal accumulation degree weakens, the probability of breakage increases, and the average particle size decreases.…”

The environmentally friendly and efficient preparation of high-purity P-xylene (PX) through suspension crystallization technology holds great significance for further advancement of the petrochemical industry. This review innovatively conducts experimental research on the entire process of PX intermittent suspension crystallization without the addition of crystal seeds in order to further clarify the details of the PX crystallization behavior. Online in situ imaging technology is used for the first time to monitor the real-time changes in the shape and particle size information on PX crystals during the crystallization process of low melting point xylene systems. Then, we derive the nucleation and growth kinetic equations of PX crystallization without adding seeds and further explore its crystallization kinetics and thermodynamic mechanism. The results can be concluded as follows. The PX crystal shape is primarily regular elongated rectangles. Without the addition of seeds, the crystal number and size rapidly increase at the moment of nucleation, the final average particle size is around 425 μm. The solution supersaturation decreased rapidly in the initial stage of crystallization and stabilized after 20 min. As the stirring speed increases, the crystal aggregation decreases, the fragmentation degree increases, and the average particle size decreases monotonically. The crystal purity is highest at 400 rpm. The mechanism by which stirring speed affects the particle size distribution of PX crystals will vary with changes in the crystallization time. The fitted crystallization kinetic equations can accurately reflect the actual nucleation and growth rates. This work is expected to theorize, model, and parametrize the PX suspension crystallization process.

Medicinal plant extracts are a promising source of bioactive minor contents. The present study aimed to evaluate the distinguished volatile content of Algerian Cymbopogon citratus (DC.) Stapf before and after the microfluidization process and their related antimicrobial and anti-mycotoxigenic impacts and changes. The GC-MS apparatus was utilized for a comparative examination of Algerian lemongrass essential oil (LGEO) with its microfluidization nanoemulsion (MF-LGEO) volatile content. The MF-LGEO was characterized using Zetasizer and an electron microscope. Cytotoxicity, antibacterial, and antifungal activities were determined for the LGEO and MF-LGEO. The result reflected changes in the content of volatiles for the MF-LGEO. The microfluidizing process enhanced the presence of compounds known for their exceptional antifungal and antibacterial properties in MF-LGEO, namely, neral, geranial, and carvacrol. However, certain terpenes, such as camphor and citronellal, were absent, while decanal, not found in the raw LGEO, was detected. The droplet diameter was 20.76 ± 0.36 nm, and the polydispersity index (PDI) was 0.179 ± 0.03. In cytotoxicity studies, LGEO showed higher activity against the HepG2 cell line than MF-LGEO. Antibacterial LGEO activity against Gram-positive bacteria recorded an inhibitory zone from 41.82 ± 2.84 mm to 58.74 ± 2.64 mm, while the zone ranged from 12.71 ± 1.38 mm to 16.54 ± 1.42 mm for Gram-negative bacteria. Antibacterial activity was enhanced to be up to 71.43 ± 2.54 nm and 31.54 ± 1.01 nm for MF-LGEO impact against Gram-positive and Gram-negative pathogens. The antifungal effect was considerable, particularly against Fusarium fungi. It reached 17.56 ± 1.01 mm and 13.04 ± 1.37 mm for LGEO and MF-LGEO application of a well-diffusion assay, respectively. The MF-LGEO was more promising in reducing mycotoxin production in simulated fungal growth media due to the changes linked to essential compounds content. The reduction ratio was 54.3% and 74.57% for total aflatoxins (AFs) and ochratoxin A (OCA) contents, respectively. These results reflect the microfluidizing improvement impact regarding the LGEO antibacterial, antifungal and anti-mycotoxigenic properties.

In recent years, nanotechnology has achieved a remarkable status in shaping the future of biological applications, especially in combating fungal diseases. Owing to excellence in nanotechnology, iron nanoparticles (Fe NPs) have gained enormous attention in recent years. In this review, we have provided a comprehensive overview of Fe NPs covering key synthesis approaches and underlying working principles, the factors that influence their properties, essential characterization techniques, and the optimization of their antifungal potential. In addition, the diverse kinds of Fe NP delivery platforms that command highly effective release, with fewer toxic effects on patients, are of great significance in the medical field. The issues of biocompatibility, toxicity profiles, and applications of optimized Fe NPs in the field of biomedicine have also been described because these are the most significant factors determining their inclusion in clinical use. Besides this, the difficulties and regulations that exist in the transition from laboratory to experimental clinical studies (toxicity, specific standards, and safety concerns) of Fe NPs-based antifungal agents have been also summarized.
