The crystal was cut for irradiation as it was growing. Cesium sputtering was used to choose a swift heavy ion (SHI) of Au3+ from a source of negative ions (SNICS). Au3+ ions of (1013, 5 x1013, and 1014 ions/cm2 ) different fluence irradiated on the semi-organic samples. A luminescence study reveals that intensity decreased due to the loss of luminescence property of the material, which is caused by swift heavy ions (SHI). The formation of intermediate energy levels which converted the photon into phonon affected the radiative transition. Hence, the peak shifted and the intensity of the peak decreased. More ions were activated with lattice disorders at higher fluences, which boosted the activation of ion interactions. Capacitance increased due to this interaction of ions hence dielectric constant increased as increased the ion fluence 1013 ions/cm2 through 1014 ions/cm2 . When a semi-organic 2-amino-5-nitropyridinium chloride (2A5NPCl) was exposed to high fluence radiation, pores, cracks, and roughness could all be clearly visible in the SEM along with the material's roughness. SHI significantly changed the surface of 2-amino-5-nitropyridinium chloride (2A5NPCl) at higher fluence. When compared to pristine, it was determined that the non-centro symmetric system in 2-amino-5- nitropyridinium chloride (2A5NPCl) was less impacted than in the other derivatives of the 2-amino-5- nitropyridinium families of crystals. Irradiated crystals' nonlinear optical properties were less than pristine; however, they were still higher than reference material KDP.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69411579","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 inhibitory potentials of SPH against corrosion of mild steel in 1 N HCl media are analyzed through weight loss, electrochemical, and surface morphological techniques. The assessment of the inhibitor effectiveness, kinetic and thermodynamic variables was done at the temperature of 303 – 333 K. The studies exhibited superior anti-corrosion efficacy of 93 % for 10 ppm SPH at 303 K and good maintenance in corrosion control is seen with temperature rise. The SPH assimilation at the metal surface follows the Langmuir adsorption model with free energy values lower than -20 KJ/mol. Potentiodynamic polarization studies evince the mode of corrosion protection to be mixed overall with cathodic predominance. Electrochemical impedance spectroscopy describes the resistive and capacitive behavior through Rct and Cdl values signifying the physical barrier prevailing on the metal surface. Surface monitoring through SEM-EDS reveals the firm adherence of SPH to the metallic surface, XRD study characterizes the corrosion products formed in the process. The roughness variables derived from AFM imaging remark the stable protective layer formed by the SPH molecules. The defensive film formed smoothes the metal surface leading to an enhanced water contact angle.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69411712","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}

High blood glucose levels are produced by poor glucose management, which alters the overall metabolic process of the body. The accumulation of abnormal (excess) blood glucose and the inability to metabolize plasma glucose causes lethal damage to the body's major organs or organ systems such as heart disease, nephropathy, retinal degeneration, sensory loss, and even premature death. Despite the administration of long-term medications, available diabetes mellitus therapy is unable to cure and unable to prevent patients from key organ damage. Diabetics have a significant financial burden, in addition to drug-drug interactions. A tremendous amount of data and proof has been amassed, proving medicinal plants' enormous potential. Plants are a naturally occurring source of therapeutic strategy for mankind. In accordance with the literature review, people who have metabolic syndrome are more likely to contract COVID-19. To overcome pandemics, we need efficient and effective herbal management. Kabasurakudineer is a polyherbal formulation that is gaining acceptance in the medical world. It may have a synergistic impact that is advantageous in the therapy of metabolic illnesses such as diabetes. Type 2 diabetes is expected to affect 640 million people by 2040, with 70% of those affected being hypertensive and predisposed to obesity and dyslipidemia.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69410335","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}
