This study used <em>aloe vera</em> as a natural coagulant to remediate wastewater. This objective was to use response surface methods to optimize operating parameters on the removal efficiency of nitrate removal through the application of response surface methodology (RSM). The influence of four factors such as <em>aloe vera</em> dosage, agitation time, agitation speed, and settling time on the removal of nitrate was examined to determine the optimal conditions for water treatment. The selected range of operating parameters is 20–40 min agitation time, 60–120 min settling time, a dosage of 0.5–1.5 g/L, and an agitation speed of 150–250 rpm respectively. Validation was carried out on the acquired data using the quadratic model. The optimal conditions for achieving the highest nitrate removal were determined as follows: 20 min agitation time, settling time of 120 min, 0.5 g/L dosage of <em>aloe vera</em> and 150 rpm agitation speed. The established conditions were confirmed through replication, resulting in 97% removal of nitrate. Functionalized groups that cause coagulation were revealed by Fourier-transform infrared spectroscopy (FTIR) and a firm, dense structure shown by scanning electron microscopy analysis suggested that contaminants had adhered to the coagulant.

Traditional methods have been widely used in cancer treatment for many years. However, the unavoidable side effects of these approaches are undeniable. Nanotechnology Through combination therapy offers the potential to improve traditional cancer treatments by reducing side effects and enhancing efficacy. In this project, we examined the potential of single-walled carbon nanotubes (SWCNTs) as advanced delivery systems for chemotherapy agents directly to tumors, as well as their role as platforms for the development of radiation sensitizers to enhance the efficacy of radiation therapy without drugs and combination therapy with chemotherapy. To confirm the successful formation of the nanoparticles, we conducted various techniques such as Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR), UV–visible spectroscopy, and X-ray diffraction (XRD) to ensure accurate verification. To evaluate the cytotoxicity of SWCNTs -Au-CUR nanoparticles, we performed MTT and hemolysis assays. Subsequently, we assessed the effectiveness of the synthesized nanoparticles against cancer cells at different concentrations, with and without the aid of X-ray. Observed results showed the correct creation and high efficacy of these nanoparticles on cancerous cells. It also showed that the presence of X-rays amplified nanoparticle toxicity, increased the ROS levels in the cancerous cells, and resulted in more effective induction of DNA damage.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"14 ","pages":"Article 102113"},"PeriodicalIF":2.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
