This study aims to modify barium hexaferrite (BaFe 12 O 19 ) by physically mixing it with cobalt ferrite (CoFe 2 O 4 ). BaFe 12 O 19 /CoFe 2 O 4 magnets were produced by ball-milling and pressing sol-gel-derived ferrite powders. The ferrite composites showed variations in magnetic properties from BaFe 12 O 19 magnets with a saturation magnetization of 69.46 emu/g and a maximum energy product of 0.4529 MGOe. For the BaFe 12 O 19 :CoFe 2 O 4 weight ratio of 4:1, both satura-tion and remanent magnetizations were increased due to the addition of CoFe 2 O 4 with high magnetizations. However, the magnetizations were reduced when the BaFe12O19:CoFe2O4 ratio was reduced to 2:1. On the other hand, the coercivity was monotonously decreased with increasing CoFe 2 O 4 . Interestingly, the maximum energy product in this study was linearly decreased with the bulk density of the magnets from 3.59 to 3.15 g/cm 3 . It is concluded that magnetic properties could be modified from a facile physical mixing of ferrites.","PeriodicalId":17782,"journal":{"name":"Karbala International Journal of Modern Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47974326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thanks to functional genomics approaches, mycorrhizae and symbioses with host plants have emerged for their fea-tures. Besides improving nutritional supply, plant-fungal interactions increase plants' tolerance to abiotic stresses such as drought, salinity and cold, as well as their resistance to diseases. Recent studies have investigated the interactions between plants and mycorrhizae, however the mechanisms often remain unclear. Indeed, plants in the field are affected by various stresses and results often appear contradictory. This review is aimed at presenting the most relevant studies in this field in order to highlight the possible benefits of mycorrhizal interactions and their application in agriculture.","PeriodicalId":17782,"journal":{"name":"Karbala International Journal of Modern Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48506858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This suggests that we can have the dried reactions at ¡20 °C for long-term storage until needed.

Hamad, Q. M. Atiyea, D. Hameed, A. H. Dalaf","doi":"10.33640/2405-609x.3275","DOIUrl":"https://doi.org/10.33640/2405-609x.3275","url":null,"abstract":"Severe acute respiratory syndrome type 2 caused by coronavirus 2 is responsible for SARS that led to the emergence of coronavirus disease 2019 (COVID-19). Recent studies have demonstrated a high correlation between secondary bacterial infections and worse outcomes and death in COVID-19 patients. The extensive use of medicines during the last SARS-CoV epidemic led to an increase in the prevalence of multi-drug-resistant germs. Nanoparticles have important characteristics and applications in health, industry, and applied fields, etc. In medical fields, they curb and stop antibiotic-resistant diseases and pathogens. In this study, strawberry leaf extract was used to synthesize copper nanoparticles. The benefits of copper nanoparticles in inhibiting the growth of Pseudomonas aeruginosa and S. aureus bacteria isolated from COVID-19 patients' sputum were tested using the agar well diffusion method. P. aeruginosa and S. aureus bacteria play a significant part in the series of bacterial infections that arise with COVID-19 infection. (1 ml) of strawberry leaf extract was mixed with (50 ml) of copper chloride solution prepared at a concentration of 2 mM at room temperature. The mixture was blended for 7 h to produce copper nanoparticles with a concentration of 2 mM as a stock solution in an environment-friendly manner. The first indication of the production of copper nanoparticles was the increase in the color intensity of the mixture after 7 h. The nanoparticles were detected using UV spectrophotometers, and a scanning electron microscope SEM, XRD, FTIR, and UV-VIS spectral, which appeared at the absorbance of two absorptive peaks, namely: 299 and 804 nm. UV-VIS spectral examination was conducted after a month and was very intense. It also showed two absorbance peaks (300 and 805 nm) with increasing intensity. This is evidence of the insolubility of the nanomaterial and its stability over the month. The scanning electron microscopy results showed that the dimensions of the prepared copper nanoparticles ranged between (46.59 and 58.82 nm). The production of copper nanoparticles in this inexpensive and environmentally friendly biological way has given excellent results in inhibiting the growth of bacteria isolated from COVID-19 patients. The effectiveness of copper nanoparticles was tested against cancerous cells isolated from laryngeal carcinoma, called HeP-2, of a 60-year-old man. The concentration of 50% of the copper nanoparticle solution, which is equivalent to 0.5 mM, gave an inhibition rate of 44.081% in cell cultures. Its effect was compared with the sensitivity of the normal cell line of liver cells (WRL-68);the concentration of 50%, which is equivalent to 0.5 mM, gave an inhibition rate of 5.997% in cell cultures, which showed a good affinity for copper nanoparticles. From this, we conclude that the copper nanoparticles were more effective in inhibiting cancerous cell lines than the normal ones. © 2023 University of Kerbala.","PeriodicalId":17782,"journal":{"name":"Karbala International Journal of Modern Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41927636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
