Therefore, development of cost- effective technologies employing attractive biomaterials to reduce the load of hazardous metals is investigated in this study. Exceeding concentrations of cadmium and iron in water bodies wrap up the choice of interest, to minimize their occurrence from industrial discharges. Thespesia populnea Seeds (TPS), as unique biomaterial, has been identified / modified chemically / activated, employed to analyse its sorption behavior in the process of trapping cadmium and iron ions and characterized using microscopic / FTIR / SEM / EDAX techniques. The role of operating factors viz. impact of agitation time, adsorbent dose, initial metal ion concentrations, temperature and solution pH in arriving the sorption equilibrium has been optimized under specified conditions.

Aguadulce) and the possibility of reducing it by using two growth hormones by soaking seeds (Kinetin 150 ppm and Gibberellin 100 ppm). This experimental work has been conducted in field and greenhouse. Three doses of NaCl (S0:0 ppm, S1:3000 ppm and S2:7000 ppm) were applied four times during the vegetative stage, the floral stage and at maturity. The obtained results show that the level of stress S2 affects the growth and photosynthesis in a significant way. Proline and soluble sugars accumulate to a higher extent in the leaves of plants exposed to salt stress (farming in greenhouse and field). The accumulation of these osmolytes represents an adaptation to salt stress. In other way, the application of hormones by soaking seeds on stressed plants induced an anti-salts stress action by stimulation of growth and photosynthesis.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":"173 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139289162","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}

It has a negative impact on nutritional supply because it is mostly manufactured from vegetable oils. Due to the possibility that oleaginous microbe lipids (such as those produced by bacteria, fungi and yeasts) could serve as an alternative raw material for the synthesis of biodiesel, the biomass and lipid buildup of Rhodococcus opacus were examined in several environmental settings. The study's current objective is to use the Response surface methodology's central composite design (CCD) to discover the ideal values of specific variables. Rhodococcus opacus, an oleaginous bacterium, was subjected to a CCD design using independent variables such as inoculum ratio, nitrogen concentration and magnesium concentration. The response variable used for the analysis was lipid content. Regarding the experimental data's lipid content%, a polynomial with a second-order model yielded good results (R2 = 96, (P ≤ 0.01)). Rhodococcus opacus produced the best results in the trials with glucose and hydrolysate with biomass concentrations of 4.75 g/L and 4.55 g/L and lipid contents of 71.18% and 66.55% respectively at pH 7. Compared to the starting values prior to optimization, these demonstrate a boost in the lipid concentration and an enhancement in the lipid coefficient. This study further supports the viability of R. opacus as a variant for the generation of biofuel from readily available, low-cost biomass resources.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139289359","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}

Among all nanoparticles, magnetic nanoparticles play a predominant role to shows their targeted drug delivery using a magnetic field, also helps to diagnose the diseases like cancer. The present study included preparation of four different mesoporous nanoparticles using the Pluronic block copolymer P123 as a surfactant template, then insert iron oxides using co-precipitation method. The resulted formed mesoporous magnetic nanoparticles are examined for structural characters by using FTIR, XRD, HRSEM and Elemental Mapping techniques. The results of X-ray diffraction (XRD) showed that the formed composites conserved ordered mesoporous structure after the formation of iron oxide nanoparticles in the pores. FTIR results indicated that the surface contains silanol group and Fe–O on the surface of the materials at 1060 cm-1 and 1020 cm-1 peaks respectively. Scanning electron microscopy (SEM) results showed that all mesoporous magnetic nanoparticles within the range of size from 50 to 100nm also possessed a regular spherical shape. These particles possessed high surface area, high pore volume and showed magnetic response sufficient for drug targeting in the presence of an external magnetic field. Elemental mapping data indicated about the percentage of all elements present in the mesoporous materials. We concluded that all four types of magnetic nanoparticles are structurally arranged in their structure with sufficient percentage of elements on their particle surface along with good size range. Further loading of drug into all types of magnetic nanoparticles decides the loading efficiency, stability and drug release nature.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139288838","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}

The biological applications of nickel oxide include the enhancement of magnetic resonance imaging, the storage of magnetic data and the purification of biological samples using ferrofluids for catalysis, drug delivery, sensors and pigments. In this study, a new inorganic (NIO) nanoparticle's potential photocatalytic and antibacterial activities were examined. A straightforward chemical process was used to effectively produce nickel oxide nanoparticles. Polyvinyl alcohol serves as a polymer capping agent.

The majority of approaches in controlling weeds in rice used herbicides including the use of glyphosate as a synthetic herbicide. However, using glyphosate in the long-term results in soil and water pollution accumulation, resulting in decreased soil fertility. This study aims to find new herbicide candidates by mimicking glyphosate's mechanism in inhibiting EPSP synthase, ACCase and photosystem II found in three types of weeds (broad-leaved and grasses and sedges). Representatives of the three types are Monochoria vaginalis (broad-leaved weeds), Cyperus rotundus (sedges) and Eleusine indica (grasses). The PyRx AutoDoc Vina docked fourteen potential bioherbicide candidate compounds at specific sites. The binding affinity value is calculated and ranked to determine the best compound as a bioherbicide candidate. In predicting biological activity, the discovery studio visualized the interaction of each complex. Benzoate and Cinmethylin are the most potent compounds as bioherbicide candidates with binding affinities of -8.2 and -6.9 kcal/mol. This interaction shows 50-59% similarity with glyphosate, so this compound inhibits PEP synthesis, amino acid biosynthesis, photosynthesis and controlling weeds in rice plants.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139288761","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}
